BugSnag

BugSnag is an error and crash monitoring service for mobile and web applications, part of SmartBear. SDKs added to the application capture crashes, ANRs and unhandled exceptions, and send them with their context to a dashboard.

Each error comes with breadcrumbs, stack traces, impacted users and affected devices, and errors are grouped and prioritised by severity and user impact. A stability score per release indicates whether an application is ready to ship or needs fixing. Performance monitoring and distributed tracing follow slow requests across the stack, and an MCP server gives AI assistants access to the data. Used during test phases, it captures failures with the details needed to reproduce them.

BugSnag is a commercial service with a free plan for one user and paid plans.
