Monitoring Tools & Alternatives
Monitoring is the largest category in DevAlt's data, with 15 tools and 5 marked open source, covering error tracking, APM, and observability rather than a single use case. Sentry is application monitoring and error tracking software, Datadog is a cloud-scale monitoring, APM, and security platform, and New Relic is an all-in-one observability platform for APM, infrastructure, and logs. The open-source options in this category are Highlight.io, SigNoz, GlitchTip, Grafana, and GoAlert, while the rest are listed with free tiers, usage-based pricing, or free trials, so this page is best used to narrow by error tracking versus full observability first. GoAlert, the fifth open-source tool in this set, is on-call scheduling, automated escalations and notifications, and SmartBear Insight Hub (formerly Bugsnag), the fourteenth tool, is error monitoring and stability management for your apps, listed with a free tier of 7,500 events a month. Honeybadger, the fifteenth tool, is error, uptime, and cron monitoring for developers, listed with a free tier of 5,000 errors a month for one user.
