Bugsnag

Error monitoring and crash reporting platform for web and mobile applications. Captures unhandled exceptions, ANRs, and performance bottlenecks across the full stack so teams can prioritize fixes by severity and user impact.

Trusted by companies such as Mercado Libre, Yelp, Square, and HotelTonight. Bugsnag differentiates with stability scores that provide an immediate health snapshot, an inbox-style view for prioritization, and native SDKs for over 50 platforms including JavaScript, React Native, iOS, Android, Go, Python, PHP, Ruby, and .NET. Integrates with SmartBear MCP for IDE error data and AI-powered fix suggestions, and supports OpenTelemetry for flexible instrumentation.

Key features:

• Stability scores and pre-configured dashboards with breadcrumbs, stack traces, and affected devices
• Error and performance monitoring with distributed tracing across the stack
• Native SDKs for 50+ platforms, from browsers and Node.js to Unity and Nintendo Switch
• Custom indexing, filtering, and search with timeline views for root cause analysis
• OpenTelemetry support alongside native SDKs, with burst protection and dynamic sampling

Development teams use it to catch crashes at critical customer moments such as purchases or bookings. Engineers debug faster with severity-based prioritization, custom alerts, code owner routing, and integration with MCP for in-IDE error context. SRE and mobile teams rely on stability metrics and ANR visibility to decide when to ship versus when to fix.
