Faultline

AI incident response

Every incident leaves a fault line. We trace it in seconds.

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

One graph. Every signal. One root cause.

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.

  1. 01

    Ingest

    Logs, metrics, traces, and deploy events stream in from every service — no new instrumentation required.

  2. 02

    Correlate

    Faultline links signals across services by causality, not just timestamp proximity.

  3. 03

    Isolate

    The graph collapses to the single node most likely to be the origin, with a confidence score attached.

  4. 04

    Resolve

    Jump straight to the offending deploy, config change, or dependency — and the matching runbook.

Features

Built for the moment everything breaks.

Six pieces of the same graph, each one built to shave minutes off the worst part of your week.

01

Signal correlation

Every log line, metric spike, and trace span lands on one timeline, automatically — no manual stitching between five dashboards.

02

Root-cause graph

A live dependency graph pinpoints the node that actually started the incident, not just the one making the most noise.

03

Blast-radius map

See every downstream service an incident touches before your customers open a ticket.

04

Auto-triage

The moment the graph identifies an origin, the incident routes straight to the team that owns it.

05

Postmortem drafts

A first-draft retro — timeline, root cause, impact — written before the incident channel goes quiet.

06

Runbook match

Faultline surfaces the fix that worked last time, pulled straight from your own incident history.

"We stopped debating who broke prod and started fixing it. Root cause used to be a 40-minute Slack thread — now it's the first thing we open."
