What is it?

Nubase is a backend and deploy layer intended to be driven by coding agents such as Claude Code or Codex through MCP tools. It bundles eight modules in one self-hostable service: Database, Auth, Storage, Assets, Functions, AI Gateway, Memory, and scheduled jobs (cron). Each project gets its own PostgreSQL database with a PostgREST-compatible REST API, and Auth follows Supabase-style conventions including JWTs and Row Level Security.

The project targets the gap between an AI-generated prototype and a running app. An agent can model tables, deploy edge functions, publish a frontend to a public CDN path, and schedule recurring work. Memory is a built-in primitive with LLM-based fact extraction and hybrid retrieval over pgvector and full-text search, rather than a separate vector store script.

The all-in-one Docker image bundles PostgreSQL, Redis, the Java backend and the Studio dashboard, and one control plane can provision multiple isolated project databases. The README lists Realtime and backups/HA as not yet implemented.

Key features

  • 01Per-project PostgreSQL database with a PostgREST-compatible REST API and Row Level Security.
  • 02Supabase-style auth with JWTs, OAuth providers, MFA and per-project API key roles.
  • 03S3-compatible object storage with public and private buckets and signed URLs.
  • 04Edge functions and static asset publishing that agents can deploy over MCP.
  • 05Built-in memory API with LLM fact extraction and hybrid pgvector and full-text retrieval.
  • 06One-line Docker image that bundles PostgreSQL, Redis, backend and Studio.

Use cases

  • Turning a prototype generated by Claude Code or Codex into a live app with a database and login.
  • Giving AI assistants persistent per-user memory backed by your own Postgres.
  • Self-hosting a multi-project backend where each project has an isolated database.
  • Publishing a generated frontend with edge functions and scheduled jobs on one self-hosted platform.

Quick start
