Each community runs its own server. One Sblurp account signs you in to all of them. ## How it fits together - **sblurp.chat** holds accounts. It signs you in and nothing else. It never sees your messages. - **A community server** holds one community: its channels, messages, files and members. Anyone can run one. The server is open source. - **The app** at app.sblurp.chat shows every community you belong to as an icon on the left. It talks to each community server directly. Servers do not talk to each other. Only the login is shared. Think of IRC networks with one shared login. ## Run your own community Not a developer? You can probably set up a server by asking an AI assistant, such as Claude, to do it for you. Read [Set up a server with AI](/docs/ai). Developer? Start with the [Quick start](/docs/self-host). It uses Render. Railway, Fly.io, DigitalOcean, any VPS, Docker Compose and Podman also work. ## Where to start | You want to | Read | |---|---| | Understand accounts and communities | [Accounts and communities](/docs/accounts) | | Join a community | [Join a community](/docs/join) | | Start a community of your own | [Run a server](/docs/create) | | Keep a community friendly | [Moderation and roles](/docs/moderation) | | Stay safe and deal with unwanted messages | [Safety](/docs/safety) | | Know what is stored about you, and where | [Your data](/docs/data) | | Run the server with help from AI | [Set up a server with AI](/docs/ai) | | Run the server yourself | [Quick start](/docs/self-host) | | Change a setting | [Configuration](/docs/configuration) | | Add a bot | [Bots overview](/docs/bots) | | Build a client or an integration | [API reference](/docs/api) | ## Search Press / to search every page.
