Code Review Linter – Free AI-Powered Code Feedback

I built Code Review Linter to help developers get quick, actionable feedback on their code — right from the browser.

It’s simple: paste a code snippet, pick a language, and the tool analyzes it using AI. You’ll get suggestions around readability, potential bugs, performance, and style — the kind of things you’d expect in a real code review.

No integrations needed. No sign-up required to try it. Just go to the site, paste code, and get feedback in seconds.

There’s a free tier that lets you run a few reviews per day. It’s meant for light use — checking a function, cleaning up a script, or learning how a piece of code could be better.

If you use it more heavily, there’s a $9/month Pro tier that unlocks unlimited reviews, longer file support, and priority processing. I kept the pricing low because I want this to be accessible, not locked behind a $20+/month paywall.

I started this because I was tired of pushing code just to wait for CI to fail or a teammate to comment on something obvious — a missed edge case, a confusing variable name, or a redundant block. This isn’t meant to replace human reviews, but to catch the easy stuff upfront.

It supports most common languages: JavaScript, Python, Go, Ruby, Rust, TypeScript, PHP, and more. The backend routes code securely, strips identifiers where possible, and avoids storing anything long-term.

Feedback so far has helped me improve the relevance of suggestions — some early outputs were too generic, but recent tweaks have made them more focused and practical.

Would appreciate any feedback, bug reports, or suggestions. I’ll keep improving it based on real use.
