Small team
Three to ten engineers, usually no dedicated SRE. You would rather have your engineers shipping than debugging.
Who it's for
Foam is for teams that ship fast and don't have time to debug.
On-call team
Foam triages the error and routes it to the engineer who should fix it. The team gets a root cause, not a flood of alerts.
Revenue on the line
When critical paths break, SLAs slip, customers lose trust, and revenue is lost.
Comparisons
How Foam compares.
Sentry vs Foam
What Sentry does
- Exceptions and stack traces
- Error grouping by frequency
- Session replay
What Foam does
- OTel-native across traces, logs, and metrics. Follows root cause across services.
- Decides what is worth your attention without alert rules or triage.
- Reports why it errored and a suggested fix.
- Alerts the appropriate engineer with the root cause.
Known pain points with Sentry
- Alert fatigue. Most teams either drown in Sentry notifications or spend significant time configuring and tuning alert rules.
- Stack traces or minified stack traces. Sentry tells you what errored but stops there. Often times their stack traces are also not very telling, making root cause hard.
- No cross-service visibility. Sentry operates per-service. It doesn't follow a request across your system.
