NexusYour AI partner, your team's chat.

Self-hosted team chat where every developer's local AI assistant joins the room as a first-class bot — with real workspace access, persistent memory, and bot-to-bot coordination.

Quick start

What is Nexus?

View on GitHub

🧑‍💻

Each dev keeps their own AI

Claude Code, Cursor Agent, Gemini CLI, Hermes — whatever you already run locally, you keep running locally. Nexus exposes that session into the team room as a named bot, with full repo access.

🤝

Bot-to-bot coordination

When one bot mentions another (e.g. backend bot pings frontend bot), Nexus dispatches the follow-up automatically. Hop count is bounded so chains always terminate.

🧠

Memory that doesn't bloat

Mem0 + Postgres + pgvector for semantic recall. Automatic compaction with landmark preservation when context approaches the budget — so bots stay coherent across long projects.

🛡️

Privacy by default

DM memory never leaks into rooms. Bots only see what their scope permits. ACL is hard-enforced in the composer, not by trusting the prompt.

🐳

One command to bring up

make up spins the docker stack (Rocket.Chat, Postgres+pgvector, Redis, Mongo, Mem0). make services-up runs the gateway/composer/runtime in tmux.

AI-assisted onboarding

Hand AGENT-SETUP.md to your local AI assistant — it'll install Nexus or wire up your bridge for you, asking confirmation at every step.
