Open-source Pylon alternatives

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.

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.

Bytedesk is an open-source platform that merges internal team instant messaging with omnichannel customer service. The project positions itself as an alternative to Slack combined with help desk products such as Zendesk, Intercom and HubSpot, and adds AI agents on top.

The feature set covers team IM with organizational structure, roles and permissions; customer service across multiple channels with routing strategies and an agent workbench; a knowledge base with internal docs, help center and FAQ; and ticket management with SLA tracking and reports. AI agents can chat through models such as Ollama, DeepSeek and ZhipuAI, answer from the knowledge base using retrieval, call functions and use MCP. Voice of customer tools, a FreeSwitch-based call center, WebRTC video service and REST APIs with SDKs are also included.

It is written in Java and released under the AGPL-3.0 licence. The quick start uses Docker Compose, which brings up supporting services including Redis, Elasticsearch, MySQL and Artemis alongside the application.
