Coverband
A Ruby gem for collecting and reporting production code coverage, tracking line-of-code execution frequency.
What is Coverband?
Coverband is a Ruby gem that collects and reports production code coverage by tracking how many times each line of code is executed in a live environment. It helps developers understand which parts of their application are actually used by real users, identify dead or rarely used code, and optimize performance based on actual runtime behavior.
Ruby developers and teams running Rails, Sinatra, or other Ruby applications in production who want to monitor code usage, identify dead code, and optimize their codebase based on real-world usage patterns.
Coverband provides unique insights into production runtime behavior that test coverage tools cannot offer, with low performance overhead and easy integration. Its ability to separate eager-loading from runtime coverage, combined with features like dead method detection and an AI-ready MCP server, makes it a powerful tool for maintaining and optimizing production applications.
