What FaultLens helps with
FaultLens is a production issue diagnosis and error monitoring platform for SaaS engineering teams. It helps teams connect errors, releases, environments, and issue context so they can investigate production failures faster.
Release-aware tracking is useful when failures appear after deployment and the team needs to understand whether a change belongs in the investigation trail.
- Attach release versions to events.
- Compare failures by environment.
- Keep deployment context close to the issue.
Who should consider it
FaultLens is a fit for teams that already receive production error signals but lose time reconstructing the surrounding story.
It is not positioned as a generic logs platform, infrastructure monitor, or full APM suite.
How the workflow is different
FaultLens keeps diagnosis close to the issue instead of scattering the investigation across dashboards, release notes, chat, and ticket comments.
The result is a focused path from production failure to useful context: what failed, where it failed, what changed, and what the team has already learned.
SDK and docs
FaultLens currently documents .NET SDK setup, browser SDK setup, Angular and React integration, release tracking, environment tracking, and production diagnostics workflow guidance.
