Maintainer stories

Real feedback from the people building the future of software.

"As a maintainer with limited time, I can't manually review every PR. Zento handles the linting and basic logic checks, leaving me to focus on the architectural decisions."

Ryan Dahl
Maintainer, Node.js

"The false positive rate is incredibly low. I trust Zento's suggestions enough to merge them automatically on minor fixes, which has sped up our release cycle significantly."

Sarah Jenkins
Lead Engineer, Vercel

"Finally, a tool that understands TypeScript's type system. It catches edge cases in generic type definitions that standard linters miss."
