Agent Reliability Platform

Your agent works in dev.
WatchLLM makes it work in prod.

Stress test with real failure scenarios. Replay any run graph. Fork from any node. Ship agents that don't embarrass you.

Stress test. Replay. Fix. Ship.

Your agent passed every test. Then it hit production and dropped your database. WatchLLM lets you rewind to exactly where it went wrong.

No credit card · Deploy in 5 min · Works with any agent framework

Agents fail silently

You don't know it's broken until a user hits it.

Logs don't replay

You see the crash. You can't reproduce it.

Every debug costs money

Rerunning agents burns API credits fast.

Stress test

Break it before users do

Run 20+ attack categories against your agent. See exactly which failure modes it can't handle.

Graph replay

Rewind to the exact moment it went wrong

Every run recorded as a graph. Every decision node inspectable. Time-travel debugging for agents.

Fork & replay

Fix once. Don't rerun everything.

Branch from any node in any run. Test your fix from that exact state. Zero wasted API calls.

Three lines. Any framework. CI/CD ready.
