What is FaultLens?
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.
Who is FaultLens for?
FaultLens is for SaaS engineering teams that need a focused way to diagnose production errors, connect them to releases and environments, and keep issue context in one investigation workflow.
Is FaultLens an error monitoring tool?
Yes. FaultLens includes error monitoring, but its positioning is narrower than a full observability platform: it focuses on production issue diagnosis and the context needed to act on failures.
How is FaultLens different?
FaultLens documentation focuses on sending useful production error context into a diagnosis workflow rather than documenting a broad observability stack.
Which SDKs does FaultLens support?
FaultLens supports any platform. Official SDKs cover .NET (FaultLens.SDK on NuGet) and browser, Angular, and React (the @faultlenshq npm scope). Any other language or runtime integrates directly using the HTTP ingestion API.
