Regression Tests for
Every Pull Request or Commit

Early PR Agents automatically generates or verifies regression tests for every commit and pull request — protects your code from breaking changes and giving AI coding tools the context to modify code safely.

AI is accelerating code, but not confidence

As AI accelerates code creation, regression risk grows and AI coding tools change code without understanding what it does
Unguarded pull requests
New code merges without verified regression tests
AI coding blind
AI tools change code without understanding existing behavior
No regression standards
Different teams follow different regression practices, if any
Zero visibility
Hard to see which PRs are protected and which aren’t

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.

How It Works

How Early PR Agents Work

Generate and verify regression tests for every pull request.
Protects existing behaviour from breaking changes during your development flow.

In four simple steps:
Detect new code
Scans changed and newly added files with low coverage for each pull request or commit
Verify or generate regression tests
Verifies existing regression tests or creates new ones for code below your defined coverage threshold
Verify automatically
Runs and validates generated tests before merge
Show protection status
Reports coverage diffs and protection metrics
The result: every pull request and commit is fully tested, verified, and visible

Key Benefits

Engineering impact
Tests that document behavior, giving AI coding tools context to change code safely
Business impact
Deliver faster, reduce regression risk, and protect releases
