Observe the real product
Run the same browser and API paths a real user depends on, from a clean state.
A ten-developer demand test
Ship agent-written code without finding the regression in production.
Failsafe is a proposed pull-request gate that opens the real app, runs critical browser and API flows, probes the edge cases coding agents skip, and returns a tested fix.
Join the first tenIt is not built yet. Ten qualified signups decide whether it should be.
The workflow being tested
The question is not whether another code scanner sounds useful. It is whether this exact gate solves a painful job for people already shipping with coding agents.
Attack the changed behavior
Exercise regressions, failure paths, load, and interactions that unit tests miss.
Return proof with the fix
Propose the smallest correction and rerun the complete flow before calling it safe.

The commitment
A real developer, not a throwaway address.
Signing up means you want this gate enough to be counted. In return:
- If Failsafe is built, the founding ten get the first year free.
- No one will add you to an email list or charge a card.
- An optional failure note can determine which failure mode matters first.
