Signal correlation
Every log line, metric spike, and trace span lands on one timeline, automatically — no manual stitching between five dashboards.
AI incident response
Faultline correlates logs, metrics, traces, and deploy events the moment something breaks — and points straight at the node that caused it. No more war-room guesswork.

Product
Faultline ingests everything your stack already emits and turns it into a single traversable graph — so the answer to "what broke" is a click, not a war room.
Logs, metrics, traces, and deploy events stream in from every service — no new instrumentation required.
Faultline links signals across services by causality, not just timestamp proximity.
The graph collapses to the single node most likely to be the origin, with a confidence score attached.
Jump straight to the offending deploy, config change, or dependency — and the matching runbook.
Features
Six pieces of the same graph, each one built to shave minutes off the worst part of your week.
Every log line, metric spike, and trace span lands on one timeline, automatically — no manual stitching between five dashboards.
A live dependency graph pinpoints the node that actually started the incident, not just the one making the most noise.
See every downstream service an incident touches before your customers open a ticket.
The moment the graph identifies an origin, the incident routes straight to the team that owns it.
A first-draft retro — timeline, root cause, impact — written before the incident channel goes quiet.
Faultline surfaces the fix that worked last time, pulled straight from your own incident history.
