About

is an open-source, MIT licensed, monitoring and alerting system by Stack Exchange. It has an expressive domain specific language for evaluating alerts and creating detailed notifications. It also lets you test your alerts against history for a faster development experience. Use Bosun's flexible expression language to evaluate time series in an exacting way. Save time by testing alerting against historical data and reduce alert noise before an alert goes into production. Runs on Linux, Windows, Mac, or any operating system supported by Go. Supports arbitrary dimensions (not just host based), aggregations, and automatically incorporating new tags as they appear. Scollector auto detects new services and starts sending metrics immediately; properly designed alerts will apply to these new services which reduces maintenance. Use our agent scollector to get monitoring of Windows, Linux, and many common applications.

About

NotiLens is a real-time alerting and monitoring platform that notifies founders and dev teams when critical events fail, spike, or go unexpectedly silent. Core functionality includes real-time push alerts, ML-powered anomaly detection that learns your baseline automatically, and silence detection that alerts when expected activity stops arriving. On-call scheduling with rotating shifts, escalation policies that auto-page the next person on no acknowledgement, and per-user DND with timezone-aware quiet hours ensure alerts always reach the right person. Broken flow detection monitors multi-step event sequences and alerts when they don't complete. AI agent monitoring tracks token usage, API response times, and cost spikes. Automation monitoring covers n8n, Zapier, and Make for silent failures. 40+ integrations: Stripe, Shopify, GitHub, Vercel, Sentry, Datadog, AWS, LangChain. SDKs for Python, Node.js, Go, Rust, Ruby, PHP, Java. MCP support for Claude and GPT. iOS and Android apps
