See every error.
Know every cause.
FailTrail captures unhandled errors, security findings, performance bottlenecks, and user context — then uses AI to group, analyze, and route them. Drop in one script tag, get a full observability dashboard.
Trusted by engineering teams shipping production software.
Capabilities
Everything you need to ship with confidence.
Stop asking users for screenshots. FailTrail captures errors, tracks performance, scans for vulnerabilities, and uses AI to surface what matters.
Autonomous Error Capture
Uncaught errors and unhandled promise rejections are captured, fingerprinted, and grouped into issues automatically — no manual reporting needed.
AI-Powered Analysis
Each issue gets an AI-generated analysis with root cause hypotheses, affected user context, and suggested fixes — so you spend less time triaging.
Security Scanning
The widget detects exposed tokens, unsafe cookies, mixed content, CSP violations, and sensitive data in URLs. Findings appear in your project dashboard.
Performance Monitoring
Real User Monitoring via sendBeacon — LCP, CLS, INP, long tasks, and resource timing aggregated per page route with p75 computed over 14-day windows.
Routing Rules
Define conditions on severity, error type, page URL, and status code to auto-route issues to the right team or escalate critical errors to Discord webhooks.
Issue Dashboard
Grouped issues with occurrence counts, environment tags, and AI summaries. Filter by status, severity, or date — and resolve them right from the dashboard.
One script tag. Full visibility.
Add the widget to any page and FailTrail immediately starts capturing errors, tracking performance, and monitoring security — no build step or config files needed.
