Start with the question that keeps you up at night

Record who knows what across your system areas - then see exactly where you're exposed when someone leaves.

02 // CONCENTRATION

Single-person dependency

See how many team members have knowledge of each system area. Find areas that rely on one person.

03 // DEPTH

Depth distribution

See depth per team member in each system area (Deep, Working, Limited). Use it to plan pairing and handoffs.

04 // PRIORITIZATION

Automatic risk labels

Areas are labeled Hotspot, Watch, or Healthy automatically. Summaries explain the main risk factors at a glance.

A clear snapshot, always ready

Your knowledge risk at a glance - hotspots, watch areas, and single-person dependencies, all in one view.

Common questions

Does it need access to our code or systems?

No. Faultline doesn't connect to GitHub, your infrastructure, or any external system. Knowledge is entered by your team - no integrations, no read access, no monitoring required.

Is this a performance management tool?

No. Faultline looks at system areas, not individuals. There are no individual scores or rankings - just team-level coverage data to help you plan ahead.

How long does it take to get started?

Most teams are up and running in under 30 minutes. Add your team, define your system areas, and map who knows what. No integrations or installation required.

How does absence simulation work?

Select any team member and Faultline shows which areas lose coverage without them - and which become single-point dependencies.

Stop guessing.
