Take the tool sales teams use to never forget a client detail and point it at the people who actually matter - friends, family, the colleague whose kid's name you keep blanking on: Monica is a personal CRM. It's a Laravel/PHP application over MySQL where each contact accumulates the texture of a real relationship: how you met, family members and pets, work changes, addresses, notes from conversations, activities done together, gift ideas and gifts given, even debts owed in multiple currencies. Two features set it apart from every contact app. Reminders with staying power: set per-contact intervals (weekly through yearly), get notified at 30 days, 7 days, and day-of, with automatic birthday reminders and CalDAV sync to your calendar. And a journal linked to contacts: write about dinner with friends, tag each person, and build a timeline that's part diary, part relationship log - plus a daily "how was your day" rating. Monica is deliberately manual and deliberately private: no social network features, no AI, no email scraping, no ads, no analytics - a quiet database of what you know about people you love, on your own server. Multiple vaults and users, labels, custom activity types, and document/photo uploads round it out. AGPL-licensed.

Your contacts live in four different address books; Contrack merges Apple, Google, LinkedIn, and Facebook into one self-hosted personal CRM you fully control. Importing merges the address books you already keep, and connecting a calendar or inbox lays past meetings and conversations along each person's timeline. Obvious duplicates merge themselves, borderline matches wait in a side-by-side review with field-level differences highlighted, and every merge can be undone for 90 days. A scribbled note such as 'met at Sarah's wedding, catch up quarterly' turns into fields, tags, dates, and reminders, while optional web research fills in roles and links with cited sources. Each morning, Pulse shows who is due a follow-up, whose birthday lands this week, and which friends have quietly gone a year without contact. Ask Contrack answers plain questions like 'who do I know in Lisbon' or 'who loves natural wine' by searching your notes and contacts locally. The map plots everyone by city, and drawing a loop around a neighborhood before a trip turns a visit into a dinner list in seconds. Households share one server while each profile keeps a private book, and the built-in MCP server lets Claude, ChatGPT, or Cursor look up context and log notes for you. One-click verified backups snapshot the whole address book, passkeys handle sign-in, and open exports mean your data leaves whenever you do. 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.

Friends drift away when nobody remembers to call; Meerkat CRM is a self-hosted personal CRM that keeps your relationships warm with birthday and stay in touch reminders, contact notes, and a living map of who knows whom. Organize every contact into circles like family, friends, or work, store spouses and children as linked relationships, and see the whole crowd on an interactive network graph that shows how people connect. Sync the same address book two ways: Meerkat runs its own CardDAV server for your phone and can also act as a CardDAV client against an external server you already use. Against each person you can keep the details that matter, dietary habits, kids names, the last conversation, plus a social style timeline of activities you have shared, from dinners to group projects. Reminders nudge you by email when it has been too long, with upcoming birthdays surfaced on the dashboard, so catching up becomes a habit instead of an afterthought. Move data in and out freely: import CSV, VCF, and even a Monica export, export back to CSV and VCF, connect external calendars, and fire webhooks into your own automations. Use it in English, German, Italian, Spanish, or French with light and dark modes, and SSO for whoever shares the house.

Salesforce's core workflow, open-source and on your own server: Twenty is a modern CRM built as exactly that alternative. It ships the standard CRM objects out of the box: people, companies, opportunities, notes, and tasks, displayed in table and kanban views with drag-and-drop and real-time updates. Its defining technical feature is a metadata-driven data model: you define custom objects and fields in the UI, and the backend regenerates its GraphQL schema at runtime, so a new object gets working queries, mutations, filters, and sorting within seconds, with no migrations to run - adapting the CRM to your sales process never requires code changes. A REST API is auto-generated from the same schema, GraphQL subscriptions push real-time updates, and webhooks fire on record changes for external integration. A visual workflow builder automates actions like notifications and field updates, TypeScript-based apps extend the platform with custom logic and frontend components, and email and calendar sync pulls Gmail messages and meetings onto contact timelines so communication history sits next to the record. The stack is NestJS with TypeORM, PostgreSQL, Redis, and BullMQ on the backend, React with Jotai on the frontend. Self-hosting on RepoCloud means unlimited users with no per-seat licensing - the pricing model that penalizes growing teams on commercial CRMs - and your pipeline, contacts, and deal history live in your own PostgreSQL database rather than a vendor's.

Teams tired of paying Salesforce or HubSpot per seat run EspoCRM: an AGPL-licensed PHP application with a fast single-page frontend over a REST API, covering sales, support, and marketing in one uncluttered interface. The sales core is complete - leads, contacts, accounts, opportunities with customizable pipeline stages, kanban views, calendars, meetings, and calls. Email is deeply integrated rather than bolted on: IMAP sync links messages to CRM records automatically, and mass email campaigns run with reusable templates, tracking, and Web-to-Lead forms feeding the funnel. Support teams get case management and a customer portal where clients track their own tickets and access a knowledge base. The real differentiator is the Entity Manager: create custom entities, fields, relationships, and layouts from the admin UI without code, with dynamic logic showing or hiding fields conditionally - EspoCRM is as much a business-application platform as a CRM. Formula scripting handles calculated fields and record automation in the free core; the optional Advanced Pack adds visual BPM process design and workflow rules. Role-based permissions with team and territory scoping, full-text search, reports, and a straightforward REST API for n8n or custom integrations round it out. Runs on PHP 8.3+ with MySQL, MariaDB, or PostgreSQL - unlimited users, zero per-seat fees.

Warpdrive is a self-hosted sales CRM that gives business-development teams the complete Pipedrive workflow, pipelines, deal timelines, and two-way Gmail, on infrastructure they own outright. Drag deals across a Kanban board with custom stages while per-stage weighted totals, rotting-deal warnings, and saved filters keep the forecast honest without a weekly cleanup meeting. Every deal opens into one workspace where activities, notes, files, emails, and the full change history share a single timeline, with participants, followers, labels, and lost reasons attached. People and organizations carry custom fields, firmographics, and org-to-org relationships, and a leads inbox plus CSV import with an undo step keeps new data from corrupting the book. Contact enrichment from Apollo, RocketReach, and GetProspect fills empty people and organization fields, and every enriched value waits behind an explicit review step before it lands. Two-way Gmail sync threads every message onto its deal and contact automatically, and templates, signatures, merge fields, scheduled sends, and open tracking live in the same inbox. Boards, inboxes, and notifications update in real time across the team, while funnel and activity stats show exactly where deals stall and who is carrying the pipeline. An MCP server lets AI assistants query the pipeline and log activity under the same permissions, and role-based access keeps every seat scoped to its own work. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Krayin CRM gives sales teams a visual Kanban pipeline where leads flow through configurable stages — new, contacted, qualified, proposal, won, lost — with deal values tracked per stage, drag-and-drop transitions, and AI-powered document import that extracts contact details from uploaded PDFs, DOCs, and images without manual data entry. Built on Laravel 12 with a Vue.js frontend and MySQL database, the platform delivers complete customer lifecycle management through a two-stage contact model separating unqualified Leads from qualified Persons linked to Organizations, with a unified timeline displaying associated activities, notes, emails, and deals. The activity module schedules calls, meetings, and tasks on a drag-and-drop calendar with reminders and team assignment. A built-in product catalog supports line-item quoting with pricing and quantities. Email integration connects via SMTP, IMAP, and SendGrid parsing, linked to leads and contacts automatically. Workflow automation triggers actions on conditions and pushes events to external systems via webhooks. The dashboard visualizes pipeline performance, top customers, top products, and email engagement with pie charts and trend widgets. Custom attributes add text, number, date, boolean, and dropdown fields to any entity. Role-based ACLs manage team permissions per module. Extensions add multi-tenant SaaS, WhatsApp lead generation, and VoIP calling. Deploy via Docker Compose. 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 teams that have outgrown spreadsheets but balk at per-seat CRM pricing can run Django-CRM on their own server, with leads, deals, tasks, and email campaigns in one self-hosted system. Requests from website contact forms arrive automatically, email requests are imported from the company mailbox, and each gets a unique ticket and is matched against existing companies, contacts, and leads. When nothing matches, a new lead is created and later converted into a company and contact person. Deals carry products, payments, currencies, and price tiers, and the price list exports to Excel. Tasks can be individual or team-based with subtasks, memos can spawn tasks or projects, and participants chat and share files inside each one. Eight analytics reports cover the sales funnel, income forecasts, lead sources, conversions, and closing reasons. The built-in email client works over SMTP and IMAP, supports Gmail through OAuth 2.0, and links each message to its request, lead, or deal. Mass mailings are spread through the workday and can use additional mailboxes to protect managers' main accounts from spam filters. Web forms are protected by reCAPTCHA v3, IP geolocation fills in each requester's country and city, and VoIP callbacks and WhatsApp or Viber messages are supported. Object-level permissions control who can view, add, change, or delete each record, and the interface offers 22 languages. 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.

Your customer relationships deserve better than a spreadsheet and a prayer: SuiteCRM gives sales, support, and marketing teams one shared system for every account, contact, lead, and deal. Track opportunities through your pipeline with stages, amounts, and close dates, then quote and invoice directly from the won deal without retyping a single line item. Support agents work cases with queues, assignments, and email threading, while marketers build target lists, run email campaigns, and measure opens and clicks against the same records sales uses. Reports query across any modules with grouping, aggregation, and charts, export to CSV or PDF, land on dashboards as dashlets, and arrive by scheduled email so Monday's pipeline review writes itself. Workflow rules react to record changes by sending notifications, creating tasks, updating fields, or calling webhooks, quietly handling the follow-up work humans forget. Roles and security groups decide exactly which teams see which records, down to individual fields, and the audit log remembers every change. Administrators reshape the system without code in Studio, adding fields (including image and file fields), rearranging layouts, and building whole custom modules, while the REST API connects SuiteCRM to your website forms, telephony, and accounting tools. 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.

Customermates delivers a modern CRM purpose-built for teams who want practical customer management without enterprise-heavy complexity. The platform manages contacts, organizations, deals, services, and tasks through clean pipeline workflows while integrating AI agent capabilities, REST API access, webhook events, n8n automation connections, and Model Context Protocol tooling for AI-native operations. Team collaboration features include role-based permissions, comprehensive audit logging tracking every data change, and workspace organization for multi-team deployments. The deal pipeline provides customizable stages with drag-and-drop management, while task assignments and service tracking connect directly to contact and organization records for complete relationship context. API-first architecture exposes all CRM data through documented endpoints enabling custom integrations, reporting dashboards, and third-party tool connections. The n8n integration enables no-code workflow automation for lead routing, follow-up sequences, notification triggers, and cross-system data synchronization. Self-hosting requires only two files — a Docker Compose configuration and environment variables — with the published image at ghcr.io/customermates/customermates:latest running database migrations automatically on first boot. PostgreSQL provides the data layer with no additional infrastructure dependencies beyond a reverse proxy for TLS termination. The Community Edition includes unlimited users, unlimited records, full API access, n8n automation, and audit logging at zero cost. 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.

CRM mechanics applied to your actual relationships instead of a sales pipeline: Nametag is a Personal Relationship Manager (PRM). It exists to fix the things you keep forgetting: when you last talked to an old friend, their kids' names, the birthday you missed twice. Contacts are tracked with flexible attributes - names, birthdays, important dates, and free-form notes for everything else - and organized into custom groups. Where it goes beyond a contacts app is relationship mapping: you define how people connect to each other (family, friends, colleagues, or custom relationship types), and an interactive D3.js-powered graph renders your entire personal network so you can see clusters and connections at a glance. Staying in touch is automated: scheduled reminders fire for birthdays, important dates, and reach-out nudges, with optional email delivery via a Resend API key for password resets and reminder notifications. Built with Next.js, it is mobile-responsive, ships with full dark mode, and supports multiple languages including English and Spanish. Because it is self-hosted, there are no account tiers or contact limits - unlimited people and relationships, with every note about your personal life stored on your own server rather than a social-graph company's cloud. A lightweight, single-container deployment makes it one of the easiest personal tools to run.

Consolidate daily to-do lists, encrypted passwords, household spending, contacts, and family photo galleries into Personal Management System, a self-hosted private command center for everyday life. Individuals can organize recurring schedules and calendar milestones with proactive notification alerts so important appointments, vehicle servicing dates, and recurring bill renewals are never overlooked. Users can balance household budgets and track expenditure across custom spending categories, calculating monthly cash flow balances while monitoring debts owed to friends or family members. Privacy-conscious users can safeguard account credentials inside an encrypted password vault featuring quick-copy buttons and secondary lock protection for sensitive personal entries. Goal setters can track multi-step personal targets and link financial milestones directly to dedicated savings pools. Home organizers can catalog contacts, log travel destinations with mapped imagery, and maintain categorized notes containing voice memos, bookmarks, and reference materials. Collectors can sort family photos and video recordings into interactive masonry galleries with built-in lightbox previews and file download tools.

Roughly 40 integrated business apps forming a full ERP: Odoo's open-source suite runs companies end to end. The Community Edition, licensed LGPL-3.0, ships roughly 40 apps covering CRM, sales, invoicing, basic accounting (journals, chart of accounts, taxes, reconciliation), inventory and warehouse management with multi-step routes, manufacturing with BOMs and work orders, purchasing, project management, timesheets, HR, a website builder, and eCommerce. Each app works standalone, but they share one PostgreSQL database and one data model, so a confirmed sale updates stock, triggers procurement, and posts invoices without integration glue. The modular design means you enable only the apps you need and extend with 40,000+ community modules from the Odoo app store covering nearly any vertical requirement. Inventory supports multi-warehouse stock, reordering rules, and lot and serial tracking with barcode-ready operations; manufacturing ties BOMs, work orders, and work-center routing directly to sales demand and stock levels; and the website builder sells straight from your product catalog with payment provider integrations. You can start with just CRM and invoicing on day one and switch on inventory or eCommerce later - new apps integrate with existing data instantly because the schema is shared. The server is Python with an XML/JavaScript view layer, and because data lives in plain PostgreSQL there is no proprietary format: you can query, back up, migrate, and extend business data directly, with unlimited users and no per-seat licensing - where enterprise ERP pricing is per user per month, headcount here costs nothing.

Salesforce's platform model, 100% open-source (Apache 2.0): Corteza is a Go/Vue.js low-code platform developed under a foundation, so there is no open-core bait to grow out of. The heart is Corteza Compose: namespaces contain applications, modules define record structures the way Salesforce objects do, and a drag-and-drop page builder assembles record pages, list pages, dashboards, and charts from configurable blocks. Automation comes from a visual, BPMN-style workflow engine plus JavaScript automation scripts, so cross-application business logic - approval chains, field updates, notifications - is configured rather than programmed. Granular role-based permissions reach down to individual modules, fields, and records, mirroring real organizational hierarchies. Corteza CRM ships as the flagship application built entirely on Compose: leads, accounts, opportunities, campaigns, and cases with a 360-degree customer view, covering most Salesforce standard objects - and because it is just a Compose app, adding or reshaping modules is configuration, not a fork. Everything is reachable over REST APIs, deliberately familiar tooling eases Salesforce admin migration, and a CLI can even generate synthetic records for load-testing what you build.

GroupOffice checks your whole company in at one address: mail, meetings, projects, invoices, and files behind a single login on your own server. The built-in mail client saves messages straight onto projects or contacts, signs and encrypts with S/MIME, and shares folders and accounts across the team. Shared calendars offer team views, bookable resources, and video meetings, while address books carry custom fields and comments so customer knowledge survives staff changes. Projects gather their tasks, files, and discussions in one place, track hours as work happens, and turn those hours and costs into invoices and reports. Support tickets arrive from your website or by email and stay organized by team, and newsletters compose campaigns from templates filled with your own data. Files co-edit in the browser through OnlyOffice or Collabora, connect to desktops over WebDAV, and sync to native phone and computer apps over open protocols. Two-factor authentication, encryption, and a module system you can extend with your own tools keep the office private and shaped to how you actually work. 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.
