danmayer/coverband

• highreadme#1

  Reposition README opening to emphasize "dead code identification"

  Why:

  CURRENT

  A gem to measure production code usage, showing a counter for the number of times each line of code is executed. Coverband allows easy configuration to collect and report on production code usage. It reports in the background via a thread, can be used as Rack middleware, or can be manually configured to meet any need. **Note:** Coverband is not intended for test code coverage; for that we recommend using SimpleCov.

  COPY-PASTE FIX

  Copy

  Coverband is a Ruby gem designed to measure and report **production code usage** at the line level, specifically to **identify dead or unused code** in live environments. It shows a counter for each line of code executed, allowing you to safely remove unneeded code and optimize your application. Unlike general APM or test coverage tools, Coverband focuses purely on runtime code usage in production with minimal performance impact.

  ## Comparison to APM and Profiling Tools
  Coverband is often confused with Application Performance Monitoring (APM) tools like New Relic or AppSignal, or profiling tools like Stackprof. While these tools offer broad insights into application health and performance, Coverband has a singular focus: **identifying which lines of your Ruby code are actually executed in production.** It is not designed for general performance monitoring, error tracking, or test coverage. Instead, it provides the precise data needed to confidently remove unused code, reduce application footprint, and improve maintainability.
