How Early products use PR coverage

At Early, Pull Request Coverage is built directly into our test-generation agents and dashboard.​
Every PR processed by our agents surfaces:​
  • Coverage of touched files​
  • Average PR coverage over time
  • Where coverage gaps remain
This gives teams instant visibility into the quality of every PR, whether written by a human or generated by AI.

The Code Quality Crisis

AI code gen tools are great for accelerating your development cycles, but the massive amounts of code they create adds a lot of complexity to your codebase.

This significantly reduces the quality of your code and increases the risk of critical bugs, making fast and efficient code testing and validation more critical than ever.
