Peek is a Rails profiling tool, originally built at GitHub, that overlays a performance bar on your application showing request metrics like database queries, cache usage, and background workers. It is extensible via a plugin system of 'Peek Views' for custom metrics.
Use cases
- profile Rails requests in the browser
- show database query counts per request
- monitor Redis and cache performance in development
- add custom performance metrics to a Rails app
- debug slow pages with an in-app performance bar
When to choose
- you maintain a Rails app and want an extensible in-browser profiling bar
- you want per-request insight into DB, cache, and worker activity
When to avoid
- you need full APM with production tracing and alerting
- your stack is not Ruby on Rails
