For the past year and a half I've been building Excalibase, an open-source platform as a service. One project gives you:
Databases: Postgres 15 17 or MongoDB-compatible DocumentDB, with backups and point-in-time restore
APIs: GraphQL and REST generated from your schema, with permissions per table and role, closed by default
Realtime, storage and edge functions (TypeScript on Deno)
App hosting: deploy any container next to your database, deploy from your CI
The newest part is an MCP server. Connect Claude Code, Cursor or Codex, give it one prompt, and the agent creates the tables and permissions, deploys the app and tests it. 2.5-minute demo: https://media.excalibase.io/demo...
Excalibase is an open-source backend platform. Spin up a project and get a full
stack instantly: Postgres (15/16/17), a MongoDB-compatible DocumentDB built on
Postgres, auto-generated GraphQL + REST APIs, role-based permissions, realtime
notifications, S3-compatible storage, Deno serverless functions, and container
deploys — plus automatic backups with point-in-time restore. Runs on Kubernetes;
free during beta.
