Exceptionless is an open-source real-time error monitoring and reporting service for .NET, JavaScript, and Node applications, with clients for ASP.NET, Web API, WPF, React, Vue, Angular, and more. It collects unhandled exceptions, logs, and feature usage events, groups them intelligently, and offers dashboards, notifications, and self-hosting via Docker.

Use cases

• track unhandled exceptions in asp.net apps
• real-time error reporting for javascript and node
• self-host an error monitoring service like sentry
• collect crash reports with stack traces
• monitor error regressions and get notifications
• log feature usage events with a dashboard
• group and deduplicate exceptions automatically

When to choose

• you need real-time error tracking for .NET or JavaScript stacks
• you want an open-source, self-hostable alternative to Sentry
• you need intelligent exception grouping, stacking, and regression monitoring
• you want configurable error monitoring without redeploying code

When to avoid

• you only need simple file-based logging without aggregation
• you require APM metrics like traces and performance profiling
• you cannot run Elasticsearch/Redis infrastructure and don't want the hosted plan
• your event volume exceeds your plan's monthly limits
