Chatwoot is an open-source, self-hostable customer support platform that gathers all customer conversations into one inbox. It is presented as an alternative to Intercom, Zendesk and Salesforce Service Cloud, and aims to give businesses control over their customer data while managing conversations across channels.

The shared inbox takes in website live chat, email, SMS and messaging channels such as Facebook, Instagram, Twitter, WhatsApp, Telegram and Line. An AI agent called Captain automates replies to common questions to reduce agent workload, and a built-in Help Center portal lets you publish articles and FAQs so customers can find answers themselves. Collaboration tools include private notes with mentions, labels, canned responses, auto-assignment based on availability, custom views and filters, a command bar and multi-language support.

Chatwoot is built with Ruby on Rails and Vue and can be run with Docker, with deployment guides on its help center. The repository license is listed as 'Other', so confirm which parts are open source. A hosted cloud version is also available for teams that prefer not to maintain their own server.

Key features

  • Shared inbox across chat, email and social channels
  • Captain AI agent for automated replies
  • Built-in Help Center portal
  • Private notes and @mentions
  • Canned responses and auto-assignment
  • Custom views and filters
  • Support for multiple languages

Pricing: Hacker is free for up to 2 agents. Startups costs $19, Business $39 and Enterprise $99 per agent per month, with a 15-day free trial; extra Captain AI credits are $20 per 1,000.

Libredesk is an open-source customer support platform that you host yourself and run as one binary. It brings email, a live chat widget for your website, and WhatsApp conversations (connected through the Meta Cloud API) into a shared inbox, and positions itself as a lightweight alternative to Zendesk, Intercom, and Chatwoot. It is released under the AGPL-3.0 license.

Teams can organize conversations with tags, custom statuses and attributes, snoozing, and search. Automations tag, assign, and route conversations by rules, macros apply saved replies and actions in a single step, and auto-assignment distributes work by agent capacity. SLA management warns about conversations at risk of missing targets, and CSAT ratings and analytics track response times and resolution rates.

A multilingual help center publishes a searchable knowledge base, an AI assistant can answer chat questions from it and hand off to an agent, and an agent copilot drafts replies and summarizes threads. Roles with per-action permissions, OIDC single sign-on, activity logs, an API, and webhooks cover administration. It is written in Go and Vue and suits small and mid-sized support teams.

  • Searchable multilingual help center
  • AI assistant and agent copilot

gofly.uniqchat.comGoFly Live Chat homepage screenshot

GOFLY Live Chat is a self-hosted live chat system for customer support, built with Go for the backend and Vue with Element UI for the frontend. It is aimed at developers who want to run their own private live-chat infrastructure on Golang rather than relying on a third-party hosted chat widget.

Its backend stack includes Gin for routing, JWT-based authentication, WebSocket for real-time messaging, GORM for the database layer and Cobra for the CLI, backed by a MySQL database. Setup involves creating a MySQL database, configuring the connection in a config file, and running the compiled binary, which listens on port 8081 and can be placed behind a reverse proxy for domain access; a chat widget can then be embedded on a website or linked directly for agents.

The README carries an explicit notice that the project is intended solely for personal learning and testing, and that commercial use and any illegal or non-compliant use are strictly prohibited. It is written in Go and HTML and released under the Apache-2.0 license, so anyone evaluating it for business use should review these stated restrictions first.

Key features

  • Self-hosted live chat for customer support
  • Go backend with Gin, JWT and WebSocket
  • Vue and Element UI frontend
  • Embeddable chat widget
  • MySQL-backed data storage

Pricing: Free and open source under the Apache-2.0 license. The project's own README states it is intended solely for personal learning and testing, and prohibits commercial use.
