A free, open-source, self-hostable AI workspace for shared pages, conversations, and AI tools.
OpenSpaces brings shared workspaces, editable pages, conversations, and AI tools into one place. Run it on infrastructure you control, inspect and change the code, and connect it to supported AI services such as MuAPI.
OpenSpaces is an independent community project. It is not affiliated with or endorsed by OpenAI. ChatGPT and ChatGPT Spaces are trademarks of OpenAI.
The software is free to use. Hosting, database, and third-party AI provider usage may have separate costs; OpenSpaces does not include free model inference.
Project status: OpenSpaces is under active development. Some interface flows are prototypes or simulated, and several README claims from earlier versions described planned behavior. In particular, the current WebSocket is not a collaborative editing system; agent execution and meeting transcription are not complete production workflows. Check the code and issues before relying on a feature.
The current codebase does not yet enforce authentication and per-Space authorization consistently across API routes. Do not expose it as a multi-user service or use it with sensitive data until that boundary has been implemented and reviewed. Configure secrets and database access privately; never commit .env files or credentials.
cd server
python -m venv .venv
source .venv/bin/activate # Windows: .venv\Scripts\activate
pip install -r requirements.txt
cp .env.example .env
Edit server/.env and set MUAPI_API_KEY. For persistence, set DATABASE_URL (and DIRECT_URL if needed) to your PostgreSQL connection string. Keep this file private.
python run.py
The API runs at http://localhost:8000; its interactive docs are at http://localhost:8000/docs.
In another terminal:
cd client
npm ci
npm run dev
Open http://localhost:3000.
The API reads these settings from server/.env:
| Variable | Purpose |
|---|---|
PORT |
API port; defaults to 8000 |
HOST |
API bind address; defaults to 0.0.0.0 |
CORS_ORIGINS |
Comma-separated allowed browser origins |
DATABASE_URL |
PostgreSQL connection string |
DIRECT_URL |
Optional direct database connection string; takes precedence when set |
DEFAULT_MODEL |
Default configured chat model |
MUAPI_API_KEY |
Provider key for MuAPI-backed features |
