Welcome to Early

Early helps you generate, verify, and maintain high-quality unit tests — automatically. Acting as your AI test engineer, Early integrates into your workflows to improve coverage, catch regressions, and speed up development with minimal effort.

What You'll Find Here​

This documentation covers all Early agents and features, from one-off test generation to fully automated coverage gates in your CI — whether you use GitHub, Jenkins, CircleCI, or just your IDE.

Products​

Early Agent for Pull Requests​

Automatically run test generation during your GitHub PRs. Early scans the diff, analyzes coverage, and creates focused unit tests — ensuring every change is protected before you merge.

Early Agent for Commits​

Use this CLI agent in commit-based CI pipelines (like Jenkins or GitHub push flows). Early detects what changed in each commit and generates relevant unit tests — great for monorepos or custom workflows.
