Sentry
Application monitoring and error tracking platform that surfaces runtime exceptions, performance traces, and logs for engineering teams.
What it is
Sentry is an application performance monitoring and error tracking platform, as described on the Sentry welcome page. The Sentry platform guide lists the platforms it supports.
When it fits
Sentry fits teams running web apps, mobile software, or distributed APIs where fast incident triage matters. Sentry maps each incident to its release, pull request, and owner, as the Sentry welcome page describes. For teams that need air-gapped environments, the Sentry self-hosted guide says Sentry can run there and describes a Docker-based self-hosted deployment.
What to watch
On the managed cloud service, each plan includes a base event quota, as detailed on the Sentry pricing page. Usage above a plan's base quota is billed at pay-as-you-go rates, so teams should manage quotas to avoid surprise bills. Organizations that self-host run the install and upgrade scripts themselves and must meet the minimum Docker and Docker Compose versions in the self-hosted guide.
