Requirements

• Nodejs 24.x. Check node -v. (Recommend: Volta).
• PostgreSQL 17+. The sync engine depends on logical replication row filters with REPLICA IDENTITY FULL (draft boundary) — the bundled docker compose already runs PG 17.
• Make sure you can work with Docker. (Recommend: OrbStack).
• Ideally you work with git over ssh and have the gh cli installed.

Create app

Do not fork this repo directly. Use the create CLI to get started:

pnpm create @cellajs/cella

Read the Quickstart so you can build something unique quickly.
