Root cause, faster

Stop rebuilding the investigation trail from scratch.

When production breaks, the issue is only part of the story. FaultLens keeps errors, releases, environments, and issue context attached so your team can diagnose faster instead of reconstructing what changed.

Selective early access. If it looks like a fit, we will reach out with founder-led onboarding.

See if FaultLens fits the way your team handles production incidents.

FaultLens is in selective early access for SaaS engineering teams that want a calmer, issue-led diagnosis workflow. Leave a work email and we will reach out when rollout opens for the right fit.

Talk to us

Leaving details does not create an account yet. FaultLens is still rolling out selectively and access remains conversation-led.

Best fit for teams that...
  • Handle recurring production issues across multiple releases or environments.
  • Lose time figuring out what changed before they can fix the problem.
  • Want a narrower diagnosis workflow instead of a broader observability platform.
Current rollout

FaultLens is still being introduced carefully. That means direct conversations, founder-led onboarding, and honest fit checks instead of a wide-open self-serve motion.

The investigation trail breaks down when context lives somewhere else.

The first 20 minutes of a production incident often disappear into Slack, git blame, and whatever the last engineer remembers about the deployment. FaultLens keeps that context attached to the issue before the team has to reconstruct it by hand.

What changes in practice
Less tab churnThe issue remains the anchor while release and environment clues stay nearby.
Faster context handoffThe next engineer sees the trail instead of inheriting a half-remembered story.
Clearer next actionDiagnosis ends with a direction, not another search loop.
02

Context stays attached

Release changes, environment differences, and investigation notes stay near the issue instead of being rebuilt from memory and scattered tabs each time.

03

Focused beats sprawl

We'd rather do one thing well than build a platform that does everything badly. FaultLens is intentionally narrower so the path to a diagnosis is shorter.

One investigation trail. No scattered tabs to close at the end.

Start with the issue. Pull in what changed. Check the environment. Leave with a clear next action. The whole path stays in one place so the team does not have to piece the story together again.

01

Issue

A production error appears. Do not start a search. Open the issue that needs explaining and stay anchored to it.

02

Release

Bring recent deployment history into the same view while the issue is still in front of you. See what changed without switching tools.

03

Environment

Check runtime differences before the diagnosis drifts. Production vs staging. EU vs US. Keep the signal close to the issue.

04

Next action

Leave knowing what to check next, not with a pile of half-closed tabs and a Slack thread to re-read tomorrow.

AnchorThe issue never loses priority.

The workflow begins with the production problem that needs explaining, not a hunt across dashboards.

Connected contextRelease and environment clues stay near the issue.

Teams can see what changed and where it changed without reconstructing the path from memory.

Operational outcomeThe investigation ends with a clearer next action.

That makes handoff easier and repeat incidents easier to understand when they happen again.

FaultLens is intentionally narrower so production diagnosis can be clearer.

The product is designed around focus over breadth, context over tool sprawl, and practical diagnosis over platform theater.

What that means for the team
The issue stays centralTeams do not have to leave the investigation trail to recover the release, environment, or next action.
Context arrives earlierThe first useful clues show up near the problem instead of after a fresh round of Slack and tab chasing.
Focus over breadthFaultLens is built for issue-led production diagnosis, not for becoming another all-purpose ops surface.
Context over noiseThe workflow keeps the issue, release, environment, and surrounding clues close instead of spreading them across separate tools.
Designed for the incident, not the demoFaultLens is built around how teams actually debug - under pressure, context switching, needing the next useful action fast. Not for a polished walkthrough.

Still rebuilding the investigation trail by hand?

If production diagnosis is costing your team time it should not, leave a work email and a little team context. If FaultLens fits the way you debug, we will reach out with next steps for early access.
