FailLens

FailLens is a web app (with lightweight SDKs) that captures user-facing errors and failed flows, then turns them into actionable UX fixes. Instead of just logging stack traces, it records the exact UI state: form inputs (redacted), clicked elements, validation messages, network failures, and the copy the user saw. It clusters incidents by “user intent” (e.g., checkout, signup, password reset) and highlights the most common friction points, with a replayable step timeline and suggested remediation patterns (better microcopy, inline validation, retry logic, clearer permissions prompts). It’s built for product and UX teams who don’t want to live in engineering tools. Realistically, you won’t beat incumbents on raw crash reporting; you win by focusing on UX failure analysis, privacy-safe capture, and fast prioritization that ties directly to conversion loss and support volume.
