About Bugsnag

Bugsnag is a commercial monitoring product for web and mobile applications, now part of SmartBear. It helps development teams find bugs and crashes quickly, fix them and release stable versions, with a focus on how errors affect real users.

Error monitoring offers stability scores as a snapshot of app health, an inbox that ranks bugs by severity and user impact, and dashboards that show breadcrumbs, stack traces, affected users and devices. Performance monitoring tracks rendering performance, memory use and CPU use, with real user monitoring and OpenTelemetry compatibility so customers keep ownership of their data. Distributed tracing follows requests across the stack, and a SmartBear MCP server is available for debugging with AI tools. Bugsnag is proprietary and vendor-hosted, with a free trial, demos, documentation and a pricing page.
