Sentry is an error monitoring and performance tracking service reached as an external API: a small SDK in the application captures errors and sends them to Sentry's servers over HTTP.

Nothing runs on the application's own server; the SDK only sends telemetry out. There are SDKs for React, Next.js, Node.js, Python and others, and once one is dropped in it starts reporting. It catches unhandled exceptions, logs stack traces, groups similar errors and alerts on spikes, and its performance monitoring tracks request latency, slow queries and frontend render times.
