AI is accelerating code, but breaks behaviour silently

As AI accelerates code creation, regression risk grows and AI tools change behavior without understanding the full flow
High regression risk
Large codebases can’t change safely without verifying regression impact
AI coding blind
AI tools change code without understanding existing behavior
No regression standards
Every repo follows different quality benchmarks with no guardrails
Low visibility
It’s hard to see protection status and risk across repositories

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

Verified regression behavior for your entire codebase

Early Repo Agents analyze your repositories, understand flows and connections, and, if needed, generate missing regression tests automatically that  document behavior and give AI coding tools the context to modify code safely, bringing standardization, protection, and visibility across your org.

In four simple steps:
Onboard
Integrate to your source control and CI to map your codebase
Analyze
Detect regression risks across mapped flows
Generate & Verify
Create and validate missing regression reports and feedback loop to coding tools
Track
View protection status and regression across the repository
The result: verified regression behavior, stronger protection, and complete visibility into quality at repository level.
