It gives users a mix of audits, developer tools, examples, and technical guides that help catch issues earlier and act on them faster.

What's the story behind your product?

CodeAva's answer:

CodeAva stands for Automated Validation Assistant. It was created around a simple frustration: too many quality checks happen too late, across too many disconnected tools. The goal is to make validation faster, clearer, and more useful for teams that ship real code, real websites, and real products.
