Watch a crew of five agents build your idea
Product Owner → Engineering Lead → Backend → Frontend → Test — streamed live, one handoff at a time.
How it works
Five agents, one pipeline. Each one reads what came before, does its job, and hands off to the next — live, streamed straight from a real run.
- 01
Product Owner
Turns your idea into a lean PRD — what to build, what to leave out, and why.
prd.md - 02
Engineering Lead
Designs the system: the backend's structure, and the API that connects it to the UI.
design.md - 03
Backend Engineer
Writes the backend in plain Python — no frameworks, no dependencies.
backend.py - 04
Frontend Engineer
Builds a real page that calls that backend, live.
index.html - 05
Test Engineer
Reviews the code, writes tests, and leaves a README for how to run it all.

# your OpenAI key never leaves your browser — held in memory for this tab, sent only with your own run, never logged or saved anywhere.
# curious how the crew is put together? clone the repo and tweak agents.yaml / tasks.yaml to see how it changes the result — every agent here runs on gpt-5.4-mini.
