Spend less
Claude or Codex plans the work and checks it. A cheaper model does the typing. Five kinds of worker to choose from, some free.
Free and open source
Stuntman
Your coding agent doesn’t do its own stunts.
You pay for the smartest AI, then watch it burn your limit on typing. Stuntman keeps it thinking and checking, and sends a cheaper model in to do the stunts.
You pay for the smartest model. Then you watch it burn your limit on boilerplate.
What you get
Keep working through the limit
Hit your usage cap and the job moves to another worker. It picks up where it stopped.
Projects that remember
Every project keeps its own memory, so tomorrow’s session starts where today’s ended.
A second brain
One knowledge graph across all your projects, so an agent finds what you already solved.
The Floor
A live pixel board of every agent you have running: who’s working, who’s stuck, who needs you. Reply from the board.
A launch plan in one command
Competitors, market size, pricing and a week-by-week plan, then attacked by critics before you see it.
Same job, two ways
One head-to-head: build the same landing page. The expensive model alone, against Stuntman. Measured from the tools’ own usage reports.
| Expensive model alone | Stuntman | |
|---|---|---|
| Cost | $4.92 | $0.65 |
| Time | 18 min, never finished | About 3 min |
| Review | Marked its own homework | Passed first time |
| Result | The slightly nicer page | About 90% of it |
How it works
The smart model plans
It reads your code and writes a brief with no decisions left open.
The stunt double works
A cheaper model follows the brief, fast and without supervision.
The smart model checks
It runs the tests itself and sends fixes back. It trusts nothing.
Fair questions
- Do I need to pay for another AI?
- No. It runs on the subscription you already have, plus free or cheap workers.
- Isn’t cheap code bad code?
- Cheap models are bad at deciding what to build. Give them a tight brief and a strict reviewer, and they’re fine.
- Does it work with Codex?
- Yes. Claude Code or Codex can lead, and either can send the work out.
