Fasterer is a Ruby command-line static analysis tool that scans your codebase and suggests performance improvements, such as replacing Array#select.first with Array#detect. It is inspired by the fast-ruby project and configurable via a .fasterer.yml file.

Use cases

• find slow ruby idioms in my codebase
• lint ruby code for performance anti-patterns
• suggest faster alternatives like detect instead of select.first
• run performance checks in CI or pre-commit hooks
• exclude vendor files from performance analysis

When to choose

• you maintain performance-sensitive Ruby code like frameworks or Rack middleware
• you want automated suggestions for faster Ruby idioms
• you want a lightweight performance linter integrated into CI

When to avoid

• you have a typical Rails app where readability matters more than micro-optimizations
• you need general-purpose linting beyond performance suggestions
• you expect the suggestions to always be safe to apply blindly
