Catch every error before your users do
Real-time error tracking software for modern applications. Capture every exception with full stack traces, source map support, and contextual breadcrumbs. Smart grouping cuts through noise so your team fixes what matters — not what duplicates.
Full context for every exception
When an error occurs, context is everything. Mihari's crash reporting automatically captures the complete stack trace, browser and OS information, user session data, and a timeline of breadcrumbs leading up to the exception. Your team sees exactly what happened, in what order, and for which user — without reproducing the bug manually.
- Full stack traces with original source code via source map support
- User session replay with breadcrumbs timeline leading to the error
- Browser, OS, device, and network metadata captured automatically
- Custom context tags for environment, feature flags, and A/B tests
- Lightweight SDK (<10KB gzipped) with zero impact on page performance
TypeError: Cannot read property 'id' of undefined
Noise down, signal up
A single bug can generate thousands of identical error events. Mihari's application monitoring uses fingerprinting algorithms to intelligently group duplicate exceptions into unique issues. See occurrence counts, trend indicators, and affected user counts at a glance. Prioritize by impact, not by volume — and assign issues to the right team member directly from the dashboard.
- Fingerprint-based grouping that merges duplicate errors into unique issues
- Trend indicators showing errors that are growing, stable, or declining
- Affected user count and impact score for data-driven prioritization
- Custom grouping rules for fine-tuned control over issue classification
- Merge and split issue groups manually when automatic grouping needs adjustment
Debug with original source code
Minified stack traces are useless. Upload your source maps to Mihari and see the exact original line of code that caused each error. View local variable values, function arguments, and surrounding code context. Source map support works with JavaScript, TypeScript, and any language that compiles to JS. Your source maps are encrypted at rest and never exposed publicly.
- Upload source maps via CLI, API, or as part of your CI/CD pipeline
- View original TypeScript, JSX, or compiled code with error line highlighted
- Local variable inspection showing values at the exact frame of failure
- Source maps encrypted at rest and never publicly accessible
- Support for JavaScript, TypeScript, and any compile-to-JS language
Know which deploy broke things
Tag errors by release version and see exactly when regressions were introduced. Mihari overlays deploy markers on your error rate timeline so you can instantly correlate spikes with specific releases. Track error budgets per release, identify the commit that caused a regression, and decide whether to roll back — all from one view.
- Deploy markers overlaid on error rate timelines for instant correlation
- Per-release error budgets and regression detection with auto-alerts
- Commit-level resolution linking errors to the exact code change
- Automated rollback recommendations when error rates spike post-deploy
Works where your team works
Errors are only useful if the right people see them. Mihari integrates with your existing development workflow — GitHub for automatic issue creation and suspect commit detection, Slack for real-time notifications, Jira for ticket management, and PagerDuty for critical alert escalation. Resolve errors without leaving the tools you already use.
- GitHub: Auto-create issues, link commits, detect suspect changes
- Slack: Real-time notifications, in-channel resolution and assignment
- Jira: Two-way sync between error groups and project tickets
- PagerDuty and Opsgenie: Escalate critical errors to on-call engineers
- Webhooks: Send error events to any custom endpoint or internal tool
Performance monitoring, built in
Errors don't happen in isolation. Mihari tracks transaction performance alongside exceptions so you can see whether an error is causing slowdowns — or whether a slow endpoint is triggering timeouts and cascading failures. Monitor Apdex scores, throughput, and response times without deploying a separate APM tool.
Transaction Tracing
Trace every HTTP request through your application. See database queries, external API calls, and cache hits.
Apdex Scoring
Industry-standard user satisfaction scores. Set custom thresholds per endpoint and alert on degradation.
N+1 Detection
Automatically detect N+1 query patterns and slow database queries. Get suggestions for optimization.
