elmah.io
Cloud error logging and uptime monitoring service for .NET applications.
elmah.io is a cloud-based error logging and monitoring service for .NET developers. It collects uncaught exceptions and structured log messages from .NET web applications, mobile apps, and client-side JavaScript into a searchable cloud store, helping teams identify, diagnose, and fix issues in production.
Core capabilities include Error Management with intelligent error grouping, anomaly and burst detection, and advanced full-text and structured search. Uptime Monitoring pings HTTP(s) endpoints from multiple regions, while Heartbeats tracks scheduled tasks and services. Deployment Tracking integrates with Azure DevOps and Octopus Deploy to correlate releases with logged errors. Notifications reach teams via email, Slack, and Microsoft Teams, with a rule engine and App Store for further integrations. AI features include Bugster, an AI debugging companion that analyzes stack traces, an MCP server for querying logs from tools like ChatGPT and Claude, and AI-powered bot detection.
The service supports major .NET web frameworks, logging libraries such as Serilog, log4net, and NLog, CMS platforms like Umbraco and Sitefinity, and mobile logging for Xamarin and Uno Platform. It is packaged with a free trial requiring no credit card, and unlimited applications are available on any plan.
