When a customer emails your support address, starts a live chat, or asks a question from your help center, opendesk lands it in one shared ticket inbox where every change appears live for the whole team. Agents work a single queue where tickets carry status, priority, assignee, team, tags, and an SLA clock, with internal notes, merging, snoozing, and bulk edits for busy days. Customers chat through a widget that offers identity verification, typing indicators, and 14 languages, and each widget can route to its own team and topics. Support leads publish collections and articles to a public help center, set SLA targets per priority, run automation rules on ticket events, and read reports on volume, response and resolution times, breaches, and CSAT. Ollie, the built-in AI, uses that help center to answer chats, draft replies, summarize threads, triage tickets, and translate both ways, through any Anthropic or OpenAI-compatible provider including local models. Admins can switch it off. Replies leave from your own address through Google, Microsoft, or any SMTP server. Developers connect Linear, GitHub, Jira, Sentry, Slack, Stripe, and any MCP server, or build on the REST API, signed webhooks, and a realtime socket. Desktop apps for macOS, Windows, and Linux and a native iPhone app keep agents reachable.

Support tickets that repeat the same twelve questions all week can answer themselves when Basjoo turns your website and documents into an embeddable AI support agent you host yourself. Knowledge bases are built independently of agents, fed by crawling a single page or an entire site, or by uploading PDF, Word, Excel, HTML, and text files that are parsed into searchable chunks. Visitors chat through a widget added with one script tag, in a floating bubble, inline frame, or iframe, and answers stream back with source citations so people can verify what the bot claimed. A curated question and answer index is matched before retrieval, which means correcting a wrong answer takes effect immediately without reindexing the whole collection, and a keyword fallback mode can answer matched questions with no model key at all. When a conversation needs a person, operators watching the live session wall can take over, reply with saved macros, release the chat back to the bot, or resolve it, with business hours deciding when the bot is off duty. Lead capture forms, an unanswered question queue that groups repeats into future answers, thumbs feedback rolled into analytics, and signed outbound webhooks for seven event types round out the operator side.

LibreDesk unifies live chat, email, and future channel integrations into a single agent inbox where every customer conversation converges regardless of origin, replacing per-seat-priced tools like Zendesk, Intercom, and Freshdesk with a zero-cost alternative that has surpassed 2,000 GitHub stars. Built on a Go backend with a Vue.js 3 and ShadcN UI frontend, it ships as a single binary requiring only PostgreSQL and Redis. The embeddable live chat widget drops onto any website with a snippet, while the AI assistant handles initial customer queries using answers grounded in your knowledge base before escalating to human agents when needed. Agent copilot drafts replies, summarizes conversation threads, and rewrites messages for tone adjustment directly within the inbox interface. Automation rules trigger on conversation events to tag, assign, and route tickets based on configurable conditions, while auto-assignment distributes workload by agent capacity or custom criteria. SLA management tracks response and resolution time targets with breach notifications, and automated CSAT surveys measure satisfaction after conversation closure. Macros save frequently sent responses as reusable templates that simultaneously set tags and assign conversations. Role-based access control provides granular per-action permissions for teams and individual agents, and SSO supports Google, Microsoft, and any OIDC provider. The HTTP/JSON API and webhook system enable custom integrations with external tools.

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.

Vocero CRM turns WhatsApp into your sales floor, with a shared team inbox, a visual pipeline, and an AI agent that answers customers using only what your business taught it. Incoming messages land in a three-column inbox within two seconds, showing sent, delivered, and read states, enforcing the official 24-hour window, and offering approved templates when it closes. Every person who writes becomes a contact automatically and enters a Kanban pipeline you can rename, where dragging a card, adding notes, or archiving a lead takes seconds. The AI agent learns from question-and-answer pairs and free-text knowledge blocks, and answers only from what it knows. It bundles message bursts into one reply and hands the conversation to a human whenever the customer asks or the rules say so. Before the agent ever meets a real customer, the Laboratory sends six simulated customers at it, from the decided buyer to the angry one, and an independent judge scores each conversation from 0 to 100 with findings and one-click fixes you can re-test after every change. Owners create team accounts, message templates sync their approval status from Meta, and WhatsApp tokens sit encrypted at rest while every customer record stays on hardware you own.

Add a live support desk to any website with Live Helper Chat, where visitors talk to operators or bots and you own every transcript. Site owners paste a generated embed snippet into any page, and the start-chat fields are customizable. Chats are routed by department, language, location, or custom attributes, wait in a priority queue, and move between agents. Operators, departments, and simultaneous chats are unlimited. Agents watch a visitor type before the message is sent, read pages visited and time on site in the online visitors list, and send proactive invitations to people who linger. Voice, video, and screen sharing run through Jitsi or Agora, and a screenshot shows what the visitor sees. Bot designers chain triggers and actions in a visual builder, call ChatGPT, Gemini, Ollama, Rasa, or any REST API, and hand the conversation to a person when needed. Incoming email becomes tickets beside chats, and extensions connect Telegram, WhatsApp, Facebook Messenger, and Twilio SMS. Staff answer from the browser, a desktop app, a Chrome extension, or iOS and Android apps. Management tools include roles, groups, statistics, transcripts, and an archive, and extensions add two-factor login, LDAP, and single sign-on. It suits banks, healthcare teams, universities, and game studios that must keep chat data in house.
