Describe a service.
Ship it.
Skipper turns plain English into a tested, running backend service — routes, types, validators, and unit tests. It iterates until it works, like a compiler for backends.
How it works
A closed loop — closer to compilation than conversation.
Tools like Claude Code or Codex keep you in the loop. Skipper takes the human out of the iteration — the review-and-refine cycle happens inside the agent itself.
Describe it
Write what the service should do in a plain-English prompt.md — or hand it an OpenAPI 3.1 spec for precise control.
Generate, test & iterate
Skipper closes the loop itself: it generates the code, type-checks it with a sound type checker, runs unit tests, and retries until it passes — no back-and-forth from you.
Run it
npx @skiplabs/skipper run starts the service in a container at localhost:3000. No local toolchain required.
What you get
Built for stateful, real-time services.
Stateful & real-time
Built for multi-user, collaborative, real-time apps — managing state is what the reactive Skip Runtime does best.
Talks to the outside world
Fetch and combine data from external APIs as first-class reactive inputs.
Sound, incremental types
A from-scratch TypeScript type checker gives the agent fast, trustworthy feedback as it iterates.
Tests, generated
Unit tests are generated and executed as part of every build, then handed back as a quality gate.
Multi-model routing
Each task is routed to the best-fit model rather than forcing one model to do everything.
Zero-cost caching
Every AI call is cached by content hash — re-running unchanged work is instant and free.
What you can build
From a sentence to a real service.
Skipper generates the backend — where the logic and state live. Pair it with a frontend from Lovable, Vercel, or Replit for a full app.

Pricing
Pay as you go.
Buy credits and spend them as you build — no subscription. Caching means re-running unchanged work is free, so you only pay for new generation.

Skipper is in beta — the focus is correctness over cost. Caching keeps re-runs free.
