What is Peek?
Peek is a profiling tool for Ruby on Rails applications that displays performance metrics in a bar at the top of the app. It helps developers monitor database queries, cache usage, background jobs, and other services in real-time to identify performance issues. Originally built at GitHub, it provides an extensible platform for adding custom monitoring views.
Rails developers and teams who need to monitor application performance during development, staging, or for specific users in production. It's particularly useful for identifying bottlenecks in database, caching, or background job systems.
Developers choose Peek because it's an extensible, Rails-native profiling tool that integrates seamlessly into the application. Unlike generic monitoring tools, it allows custom views and adapters, providing tailored insights without disrupting the development workflow.
