Frontend error monitoring and intelligent crash triage
Analytics and frontend observability together in one platform. Automatically capture uncaught JavaScript exceptions, promise rejections, stack traces, and action breadcrumbs.
Why separate error monitoring tools fragment workflows
Running independent crash monitoring services like Sentry alongside separate analytics creates disjointed stacks, multiple heavy client SDKs, and billing overhead for duplicate visitor data.
- xTraditional error monitors inject 30KB-80KB SDKs that slow down initial page rendering
- xEngineers can't see whether a crash affected an important marketing route or high-value conversion funnel
- xNoise from third-party extensions and benign script errors clutters triage queues
- xHigh per-error volume pricing makes comprehensive production error tracking expensive
Unified analytics + error observability
Open Analytics captures runtime errors directly through our single 3.2KB beacon, correlating crashes directly with user paths and visitor analytics.
Browser error interception architecture
Passive global listeners capture runtime exceptions without altering application execution flow.
Window Error & Rejection Hooks
Hooks into `window.onerror` and `window.onunhandledrejection`, extracting error message, filename, line number, column, and stack trace.
Contextual Action Timeline
Attaches recent user action breadcrumbs, browser version, operating system, URL path, and device memory context.
Edge Deduplication Engine
The telemetry edge fingerprints the crash signature and increments milestone counters (5x, 10x, 25x, 50x+) with automated alerting.
Production Use Cases
How engineering and growth teams rely on Open Analytics in production.
Zero-Setup Crash Detection
Deploy without modifying your React, Vue, or Next.js components; global listeners start capturing immediately.
High-Traffic Error Storm Alerting
Receive instant desktop alerts and notifications when error velocity exceeds 10 errors within a 5-minute window.
Edge Noise Suppression
Filter out noisy browser extension errors, ad-blocker interference, and known benign warnings at the API gateway.
Captured Signals & Benchmarks
Precision telemetry captured with zero browser performance overhead.
| Signal | Unit | Benchmark | Description |
|---|---|---|---|
| Crash-Free Rate | Percentage | > 99.8% Healthy | Proportion of visitor sessions that completed without experiencing an unhandled JavaScript runtime error. |
| Error Occurrence Count | Total | Aggregated | Cumulative count of times an identical error fingerprint has been encountered across all users. |
| Affected Route | URL Path | Correlated | Direct correlation linking runtime crashes to specific page templates and user journeys. |
| Error Velocity | Errors / Min | < 2/min Normal | Real-time rate of incoming errors to detect active production regressions immediately after deploy. |
Privacy by Design & GDPR Exemption
Open Analytics processes telemetry without invasive user surveillance.
- User credentials, passwords, and authorization tokens are automatically redacted from payloads
- URL query parameters are stripped of common sensitive tokens (e.g. token, key, secret, code)
- Error stack traces contain only public JavaScript execution traces and line numbers
- 365-day automated TTL retention cleanses legacy logs automatically
