Agents can code.
Kaimo lets them build.

Developers are giving coding agents more advanced tasks and letting them run longer.

But agents can only check their code and don’t know if an app actually works.

Kaimo is your coding agent’s testing partner, identifying what’s broken so it can fix its code.
