Kumiko is an open-source (MIT) backend framework for business software. You describe the domain in TypeScript, and tenant scoping, auth and roles, an audit trail, realtime updates and a schema-driven UI follow from it. It runs on Bun and Postgres, and you can host it yourself. The npm package ships an AGENTS.md, so coding agents can work from the installed docs. PublicStatus, Offlot and CashColt run on it in production.

Could you build this?
Partial A schema-driven framework with auth, roles, and an audit trail is buildable with AI help, and the UI layer is codeable. Multi-tenant isolation and security guarantees are high-stakes and need careful architectural judgment that vibe coding alone may not provide.
What it would actually take: The stack would be Bun or Node with Postgres, a typed schema DSL that generates the API, row-level tenant scoping, and a realtime layer such as Postgres LISTEN/NOTIFY or websockets. The hard part is getting tenant isolation, permissions, and audit guarantees right and proven, which takes a backend or security engineer who has built multi-tenant systems before.
