GLPI combines helpdesk ticketing, hardware inventory, license compliance, CMDB, and project management in a single PHP application with over 6,200 GitHub stars and 500,000+ Docker pulls, offering a unified ITSM platform that replaces ServiceNow, Freshservice, and ManageEngine without per-agent pricing. The ITIL-aligned service desk handles incidents, problems, changes, and service requests with configurable SLA management, approval workflows, satisfaction surveys, and business rules that automate ticket routing, escalation, and categorization. Native dynamic inventory through the GLPI Agent discovers Windows, Linux, and macOS endpoints with deep hardware profiling, while network discovery scans switches, printers, and infrastructure devices automatically. Software and license management tracks per-user and per-core license allocations with compliance reporting, expiration alerts, and financial cost tracking across the asset lifecycle from purchase through depreciation to disposal. Data center infrastructure management provides rack visualization with U-level positioning, PDU tracking, and connection mapping. The integrated forms editor builds custom request portals for end-users, while the self-service portal lets users submit tickets, browse the service catalog, and reserve assets. Webhooks trigger external HTTP calls on events, and the High-Level REST API v2 exposes every resource for automation. A plugin marketplace offers 90+ extensions for monitoring integration, advanced reporting, and authentication. Deploy via Docker with the glpi/glpi image alongside MySQL.

Keep every ticket tied to the servers, applications, and contracts it affects with iTop, an IT service management platform that joins a configuration management database (CMDB) to a helpdesk. Agents work user requests, incidents, problems, known errors, and changes through ITIL-style life cycles, and SLA targets for time to own and time to resolve move a ticket to an escalated status when a deadline passes. The CMDB models infrastructure, virtualization, end-user devices, software, and business applications, and its impact analysis graph shows what a failing server would take down. A service catalog of services and subcategories, backed by customer and provider contracts, feeds a user portal where employees and customers submit requests from a mosaic, tree, or list, follow progress, add comments and attachments, and reopen resolved tickets. Administrators bulk-load inventory from CSV, run consistency audits to catch data-quality problems, synchronize records from external sources, and connect other tools through REST web services. Sign-in works with local accounts, LDAP, or CAS, with optional two-factor authentication through authenticator apps, email codes, or recovery codes, and the console offers dark, high-contrast, and color-blind-friendly themes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Email-driven ticketing for IT, support, and operations teams: Request Tracker turns every message sent to support@, helpdesk@, or security@ into a tracked ticket with an owner, a priority, a due date, and a complete audit trail. Staff reply to customers and comment privately to colleagues from the web interface or straight from their inbox, while requestors follow their own tickets in a self-service portal. Lifecycles built in a visual editor define custom statuses, transitions, and rights per queue, and scrips fire notifications or automated actions whenever a ticket changes. Service level agreements honor business hours, escalations trigger as deadlines approach, and scheduled tickets recreate recurring chores such as monthly patch windows. A transaction query builder, saved searches, charts, and drag-and-drop dashboards turn ticket history into reports that export to CSV or arrive by email on a schedule. Asset catalogs track laptops, licenses, and servers beside the tickets that mention them, and an Articles knowledge base feeds canned answers into replies. Time worked is logged per ticket with a My Week timesheet, approvals route sensitive requests to the right people, and PGP or S/MIME protects email in both directions. A REST2 API, a command-line client, and more than 400 extensions connect RT to the rest of your tooling. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-2.0 licensed.

Znuny turns every customer request into a ticket with an owner, a priority, a deadline, and a complete history, no matter whether it arrived by email, phone, web portal, API, or a monitoring alert. Agents work from a dashboard that lists open and new tickets, escalations, running processes, a seven-day created-versus-closed chart, upcoming events, and logged-in colleagues. Queues route tickets to the right team, and automation handles classification, escalation, notifications, and state changes, from simple email filters up to multi-step business processes. Service level agreements are tracked against every ticket, with alerts before deadlines pass and overdue items highlighted. Customers help themselves through a self-service portal and a searchable FAQ knowledge base, while agents opening a ticket immediately see who the customer is, which company they belong to, the services they are entitled to, and their full support history. Configuration items in the CMDB link assets and services to the tickets they affect, statistics and reports turn ticket data into decisions, and calendar appointments can create tickets on schedule. Administrators shape the system with over 2,000 configuration options, dynamic fields, and granular permissions. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Trusted by thousands of organizations worldwide with over 14,700 GitHub stars, Snipe-IT has been the gold standard in open-source IT asset management since 2013. Built on Laravel 12 with PHP 8.2+, it provides a comprehensive web-based platform for tracking every physical and digital asset in your organization — from laptops and servers to software licenses, accessories, consumables, and components. The check-in/check-out system assigns assets to users with full audit trails, digital signature acceptance, and automated email notifications for checkouts, approaching deadlines, expiring warranties, and low inventory. License management handles multi-seat software with seat-by-seat tracking, compliance monitoring, and expiration alerts. Custom fields let you capture organization-specific metadata, while the advanced search engine supports logical operators including and/or conditions, exact matching with is:value, fuzzy exclusions with not:value, and null checks.

For teams that answer customers by email, UVdesk is a free, self-hosted helpdesk that keeps every conversation in one shared queue. Customers have three ways in: a connected mailbox, the support portal, or a public ticket link that opens a conversation without a login. Gmail, Yahoo, Outlook, or any IMAP mailbox can feed the queue, with no limit on how many. Agents work in a threaded ticket view, where they reply, forward to a colleague, leave private notes, add collaborators, and pin important messages. Saved replies answer repeat questions, and prepared responses set a status, tag, priority, or assignment from the ticket footer. Administrators route work through groups and teams, and agent privileges decide which tickets each person may see. Workflows run events, conditions, and actions in the background, while spam settings reject senders by address, domain, or IP. A knowledge base of folders, categories, and articles, with revision history and related articles, lets customers find answers without writing in. Customers can rate the support they received, and the Kudos report lists those ratings by agent, group, team, type, priority, customer, or source. Portal branding covers a logo, brand colors, a tag line, and custom CSS and JavaScript. The community edition places no cap on agents, groups, teams, customers, or tickets. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. OSL-3.0 licensed.

With over 3,200 GitHub stars, 900 forks, and backing from the team behind ERPNext, Frappe Helpdesk delivers a modern, streamlined alternative to Zendesk and Freshdesk with unlimited agents, no per-seat pricing, and full source code access under the AGPL-3.0 license. Built on the Frappe Framework with a Python backend and Vue 3 frontend using Frappe UI, the application collects customer inquiries from email, web forms, and the customer portal into a centralized ticketing queue with complete conversation history and threaded replies. Customizable SLA rules define response and resolution timelines by ticket type or team, triggering automatic alerts and escalations when deadlines approach or are missed. Assignment rules route incoming tickets to the appropriate agents based on priority, issue type, or workload balancing, while manual reassignment and transfer between teams remains available at any time. The customer self-service portal lets users submit tickets, track status, and search a knowledge base of published help articles that reduce repetitive support requests. Agents access saved reply templates for consistent, rapid responses to common queries. Custom fields, configurable workflows, and saved views adapt the interface to match each organization's support process. Real-time updates via WebSocket push ticket changes instantly to all connected agents. The PWA-compatible interface provides mobile access without a native app. Frappe Framework compatibility spans versions 15 and 16.

With nearly 3,900 GitHub stars, over 1,800 forks, and continuous development since 2013 culminating in the v1.18.4 release in June 2026, osTicket remains one of the most deployed open-source help desk systems worldwide, trusted by organizations from small businesses to universities and government agencies. The PHP backend on Apache or IIS with MySQL stores every ticket, response, and attachment while the web interface provides separate agent and customer portal views with role-based access control across departments, teams, and individual agents. Customers submit tickets through web forms, email piping, or phone-entry by agents, and configurable ticket filters automatically route incoming requests to the correct department, assign agents or teams, set priority levels, apply SLA plans, and trigger canned responses based on matching criteria including custom field values. Agent collision avoidance locks tickets during response composition to prevent duplicate replies, while SLA plans with business hour schedules track due dates and escalate overdue tickets automatically. Custom forms and fields let organizations capture structured data specific to each help topic — from IT asset tags to billing account numbers — with configurable required and internal-only visibility. The advanced search system with saved queries and CSV export enables reporting across all ticket metadata and custom fields. The customer portal provides ticket tracking, profile management, and knowledge base access. OAuth2 plugin support enables modern email authentication with Microsoft 365 and Google. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-2.0 licensed.

CompDesk is a self-hosted help desk that gives small organizations department-based ticket queues, role-based access control, and a public Help Center without a per-agent subscription. Tickets land in department inboxes where agents work searchable queues with templates, custom fields, tags, and internal notes that customers never see. SLA policies set response and resolution targets per queue, and escalation rules push overdue tickets upward before they go stale. Requesters follow their own tickets, join public comment threads, and browse Help Center articles in English or French; agents keep the full immutable timeline behind each case. Private attachments stay out of the public file space, pass signature validation and quota checks, and can be scanned by ClamAV before anyone downloads them. Sign-in works with local accounts, Microsoft Entra ID, or any OpenID Connect provider, and four roles (User, Agent, department Admin, Super Admin) decide exactly who sees which tickets. Email notifications flow through SMTP or Microsoft 365, signed webhooks announce ticket events to other systems, and department-scoped API clients give external tools a way to open and update tickets. Runtime branding restyles the portal with your organization name, logo, and colors, and a guided setup wizard creates the first Super Admin and locks itself away when finished. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Small MSPs waste thousands of dollars annually on overlapping subscriptions for documentation, ticketing, and billing tools that don't talk to each other. ITFlow replaces that fragmented stack with a unified platform where client contacts, locations, vendors, computer assets, software licenses, domains, SSL certificates, passwords, and documents all live under one roof. The AES-encrypted password vault stores credentials with organized access controls, and domain plus SSL certificate tracking generates automated renewal alerts before expiration disrupts client services. Ticketing supports creation, prioritization, assignment, and SLA tracking, with a client portal where customers submit tickets, view invoices, approve quotes, and access their own documentation independently. The accounting module covers the full lifecycle: quotes, recurring billing, expense tracking, Stripe payment processing, and financial dashboards showing revenue and outstanding balances at a glance. AI integration through Ollama, LocalAI, or ChatGPT accelerates documentation writing and ticket responses directly within the interface. The modular architecture lets you enable only what you need, sidestepping the bloat of enterprise PSA platforms designed for organizations ten times your size. With stable releases since 2025 and zero per-user licensing, ITFlow removes the escalating costs that make commercial PSA tools unsustainable for growing teams. The PHP application deploys with MariaDB and Nginx, ready for production in minutes.

Django Helpdesk is a complete support ticketing system that gives a small business one shared place to receive, assign, and resolve customer requests. Customers write to a support address and each incoming email becomes a ticket in the right queue, with replies threading back into the same conversation. Queues separate products, departments, or clients, and each queue can poll its own mailbox and carry its own settings. The staff dashboard surfaces unassigned tickets the moment they land, and agents claim work, reassign it, or hand it to a teammate. Every ticket holds its follow-up history, attachments, priority, due date, and custom fields your team adds for the details generic forms miss. Duplicate reports merge into a single ticket, and saved searches keep recurring questions one click away. Customers help themselves first through the built-in knowledgebase, then submit and track their own requests in a portal that hides internal notes. A REST API creates and updates tickets from other systems, and webhooks push ticket events into chat tools, CRMs, or billing scripts. An embeddable iframe form drops ticket submission into any existing website, and spam filtering keeps junk out of the queue.

A deliberately simple ticketing system standing in for both Zendesk and Jira: Peppermint handles internal staff requests and external customer support alike. The stack is modern full-stack TypeScript: Next.js and React over Prisma and PostgreSQL, which makes it light to run and approachable for developers extending it. Ticket creation is straightforward - a markdown editor with file uploads, assignment, status tracking, and a logical workflow that new agents grasp without a manual. Mailbox integration converts email into tickets automatically: configure SMTP/IMAP per mailbox and incoming messages become trackable tickets. Each client accumulates an interaction history, giving agents context on every past request before replying. Two touches distinguish it from bare-bones ticketing: a built-in markdown notebook with todo lists for internal documentation and knowledge sharing, and OIDC authentication so agents sign in through your existing identity provider - Keycloak, Okta, Authentik, or Azure AD. Configurable webhooks and email notifications push ticket events to third-party services. The UI is responsive from mobile to 4K, and everything works fully offline in air-gapped environments. Docker-native and scalable via Kubernetes, with an active community of 3,000+ GitHub stargazers.

With 5,700+ GitHub stars and over a decade of active development since 2012, Zammad is the open-source helpdesk platform that unifies every customer communication channel — email, live chat, telephone, WhatsApp, Telegram, Facebook, SMS, and web forms — into a single ticket management interface backed by PostgreSQL, Elasticsearch, and Redis. Version 7.0 introduced native AI features including automated ticket categorization, priority assignment, and title rewriting via AI agents that plug into triggers, macros, and scheduler jobs, plus one-click AI ticket summaries and a writing assistant — all configurable with your choice of LLM provider: OpenAI, Anthropic, Mistral AI, Azure AI, Ollama for local models, or any custom OpenAI-compatible endpoint with full audit logging of every AI action. Define service level agreements with first response, update, and solution time tracking tied to business hours calendars, with automatic escalation notifications. The knowledge base provides multilingual FAQ management with internal and public visibility. Core workflows enable dynamic ticket masks with conditional field dependencies per group. Text modules let agents insert predefined responses via the double-colon shortcut, while macros execute multi-step actions with one click. Security includes two-factor authentication, S/MIME and PGP email encryption, and single sign-on via SAML or OpenID Connect. Integrations connect to GitHub, GitLab, Microsoft 365, LDAP with nested group support, and Exchange. Deploy via Docker Compose, Kubernetes with the official Helm chart, or DEB/RPM packages. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.

ClientSt0r is a self-hosted operations platform for managed service providers that keeps client documentation, IT assets, credentials, and the service desk in one multi-tenant system running on your own infrastructure. Open any ticket and the client's active contract, the asset it concerns, the runbook that covers it, and the vault entries you are allowed to use appear alongside the conversation, so nobody switches between four products during an outage. Readiness scoring grades every client against what should be documented, explains each gap, and queues the fixes, while versioned documents with owners and review dates keep runbooks from quietly going stale. The credential vault encrypts secrets with AES-256-GCM, isolates them per client, enforces IP, geography, and time-of-day access rules, logs every reveal, generates TOTP codes, checks passwords against known breaches, and imports existing Bitwarden or Vaultwarden libraries. Asset records cover hardware inventory, IP address management, rack layouts, and printable QR labels. The service desk adds queues, SLA timers, dispatch views, time entries, quotes with electronic signatures, invoices, contracts, approvals, a workflow rule builder, a threading email engine, and guided client portal forms, while procurement, profitability reporting, CVE scanning, SSL expiry tracking, and uptime monitoring round out daily operations. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Ralph tracks thousands of assets across data centers and back offices through a unified CMDB, DCIM, and asset management platform, providing the same capabilities as ServiceNow, Device42, and Sunbird dcTrack without per-asset licensing fees. Used by Allegro in production and backed by over 2,500 GitHub stars, it is built on Python 3 with Django and Django REST Framework. Interactive data center floor plans support drag-and-drop rack placement, front and rear rack views showing U-level asset positioning, power consumption tracking per PDU, and ethernet and fiber connection mapping. The back office module manages laptops, desktops, printers, mobile phones, and accessories with user assignment tracking, warehouse inventory, stock-taking audits, and automated loan workflows. IP address management handles network environments with DHCP and DNS integration alongside network topology visualization. Software license tracking monitors per-user and per-core allocations with usage calculations, compliance reporting, and expiration alerts, while vendor support contracts track SLA agreements and warranty renewal dates. The transitions system automates asset lifecycle processes through configurable workflows that trigger HTTP webhooks, custom Python scripts, email notifications, and Puppet and Ansible configuration management integration. Custom fields extend the data model with text, numbers, dates, choices, and URLs per asset type, accessible via the REST API. Multi-tenant architecture organizes assets by regions, data centers, service environments, and business units. Deploy via Docker with the allegro/ralph image alongside MySQL and Redis.

Shelf answers the three questions every equipment manager dreads — who has it, where is it, and when is it coming back — using QR-code-first tracking where every asset gets a unique scannable label, every handover is logged with timestamps and e-signed custody agreements, and every scan captures GPS coordinates displayed on a map. Built on React Router 7 with React 19, TypeScript 5, Prisma 6 ORM, and Tailwind CSS 3 with Radix UI components, the platform generates QR codes and barcodes (Code128, Code39, Datamatrix) printable on DYMO, Brother, and Zebra label printers. The custody system records every handover with user details and generates PDF custody agreements with e-signatures for high-value items, while a complete audit trail tracks responsibility from check-out to return. The visual booking calendar prevents double-bookings automatically, supports partial check-outs and returns with segmented lifecycle bars, and handles quantity-tracked consumables alongside individually serialized equipment. Asset Models enable bulk creation of identical items with shared defaults while maintaining individual QR codes and custody histories. Location tracking displays last-scanned GPS coordinates on MapTiler maps. Supabase Auth provides email and SSO authentication, pg-boss handles background job queuing, and Nodemailer delivers SMTP email. The Shelf Companion app on iOS and Android enables field scanning and bookings. Export Asset Inventory, Asset Distribution, and Custody Snapshot reports for compliance. Deploy via Docker with PostgreSQL and Supabase. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL v3.0 licensed.

Spreadsheets and sticky notes stop scaling the day your network grows past a rack or two, so JT-IPAM keeps every address, subnet, and device in one searchable system of record. Track subnets and individual IPs with their hostnames, MAC addresses, and owners, then reconcile what you documented against what scan agents actually find through ICMP, ARP, reverse DNS, and SNMP collection from routers and switches. Connect the DNS servers you already run, from PowerDNS and BIND 9 to Windows DNS and Technitium, and flag records that have no matching address in IPAM. Pull devices and virtual machines in from LibreNMS, Zabbix, Proxmox VE, ESXi, Hyper-V, and OpenStack so monitoring and address records stop drifting apart. Draw floor plans and rack elevations, trace a cable across multiple hops, and open an SSH terminal, SFTP browser, or RDP desktop to a device straight from its address page. Route new address requests through configurable multi-stage approval workflows, distribute certificates to web servers and firewalls from central encrypted storage, and keep a full audit trail of every change and console session. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Publish the answers your team keeps repeating as a multilingual, searchable FAQ with phpMyFAQ, a knowledge base whose admin area handles writing, review, and permissions. Organize entries in nested categories that you rearrange by drag and drop, attach files, add tags and related FAQs, and let visitors leave comments. A WYSIWYG editor with an image manager writes each answer, a wiki-style revision history restores earlier versions, and a news system posts announcements. Full-text search covers every language, and optional Elasticsearch or OpenSearch backends handle larger collections. The interface covers more than 40 languages with right-to-left layouts, automatic content negotiation, and translated categories and entries. Privileges work per user and per group, so an editor can change an entry without being allowed to delete it, and categories can be limited to chosen readers. Sign in through LDAP, Active Directory, or Microsoft Entra ID, protect accounts with two-factor authentication, or try experimental passkeys. The dashboard charts 30 days of visits, lists inactive FAQs, and checks installed files against published hashes. Export entries to PDF, publish a dynamic sitemap, back up your content, and filter spam with built-in protections. Dark, light, and high-contrast themes keep the public site comfortable to read. Scripts and AI assistants reach the knowledge base through a REST API with an OpenAPI specification or an experimental MCP server, and plugins extend it.
