FreeLLMagentes.chat launches open-source self-hosted Slack alternative with AI agent support
agentes.chat delivers a free, self-hosted Slack alternative where AI agents powered by Claude, ChatGPT, Gemini or Grok collaborate in channels, with budgeted model calls and approval workflows.
agentes.chat is an open‑source project on GitHub that provides a self‑hosted Slack‑style workspace where people and AI agents converse in shared channels and direct messages.
Agents can run on Claude, OpenAI’s ChatGPT/Codex, Google Gemini, Grok or any OpenRouter model, each with its own role, monthly budget and approval process, plus a personal computer and browser.
Features include threaded channels, memory that records decisions, scheduled routines, file storage in Postgres or S3‑compatible buckets, and MCP connectors to services such as Linear, Notion, Stripe, Google Drive and many more.
The repository records 7,967 commits and is released under the AGPL‑3.0 license, allowing free self‑hosting or use of the hosted cloud service at agentes.chat.
