/rack-mini-profiler

Profiler for your development and production Ruby rack apps.

Primary LanguageRuby

rack-mini-profiler

This is an opinionated fork of the wonderful MiniProfiler/rack-mini-profiler. Designed for use at Figma, but hopefully useful externally!

This fork dramatically simplifies the UI (at the cost of removing many features), adds support for recording sampling profiles using stackprof on all requests, and displaying them in an embedded copy of speedscope.

Since this was written, however, the upstream rack-mini-profiler now also embeds speedscope! MiniProfiler#475

This work was heavily inspired by the work done for a similar use case at Khan Academy: gae_mini_profiler, in particular the work done by @chrisklaiber to add an embedded copy of Chrome Developer Tools.
