Description
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.

Could you build this?
No Building a complete Backend-as-a-Service (like Supabase) with multi-engine databases, MongoDB-over-Postgres wire protocol translation, secure Deno sandboxing, and real-time CDC engines requires heavy systems and infrastructure engineering.
What it would actually take: Requires deep systems architecture: custom Postgres extensions or wire-protocol proxies (such as FerretDB) for Mongo compatibility, isolated multi-tenant execution sandboxes (Deno/V8 isolates or Firecracker microVMs), logical replication decoding (pgoutput) for real-time pub/sub, and automatic schema-to-GraphQL/REST compilers.
