How it works

01

Cuts through the noise

Foam monitors every error across every service. Groups them by root cause. Only flags what's new or spiking. The rest stays quiet.

Root cause: a config change in queue-worker flooded card-store, which exhausted checkout's connection pool.

02

Finds the root cause

Foam investigates across your entire stack including services that aren't even remotely in the original error.

03

Notifies the right person

Foam identifies who's responsible based on the root cause, not git blame. They get a Slack message with the RCA.
