DeesseJS is a TypeScript-first ecosystem of libraries and tools for building production SaaS. Every package is MIT-licensed, end-to-end typed, and built to compose with the others. No lock-in, no proprietary runtimes, no magic — just solid, boring, modern choices.

• Comprehensive foundations — error handling, FP monads, ORM, RPC, admin UI, cloud
• Modern tooling — pnpm, Turborepo, Drizzle, better-auth, shadcn/ui
• Standards-driven — Standard Schema for validation, JSON-RPC 2.0 error codes, Protobuf-compatible wire formats
• Open-source, self-hostable — every library is MIT, including the cloud control plane
