I built an AI that reviews every PR automatically (because nobody was reviewing mine)

The article describes how the author built "PushSafe," an AI tool that automatically reviews every pull request (PR) on GitHub by posting inline comments on code diffs. It was created because the author was shipping code quickly with AI assistance but missing critical bugs—such as null errors, missing awaits, and hardcoded secrets—that caused production crashes and user churn. PushSafe is free, requires no credit card, and aims to catch basic but embarrassing mistakes that a human reviewer would normally spot.

I've been vibe coding for months. Cursor writes the code. Claude fixes the bugs. I ship. Fast. Really fast. But nobody was reviewing my code. Not me. Not a teammate. Nobody. I'd read the diff quickly, it looked fine, I merged it. Then a user found the bug I missed. They didn't email me. They just left. The real problem with vibe coding AI helps you write code faster than ever. It does not stop you from shipping broken code. You prompt Claude. It writes 200 lines. You read it once. Looks fine. You merge it. But did you check what happens when the user object is null? Did you check what happens when the API times out? You didn't. Nobody does. The bugs that kill your SaaS They're not exotic. They're embarrassing. js // null not handled const user = getUser id console.log user.email // crashes in prod // missing await const data = fetchUserData id return data.profile // returns Promise not data // hardcoded secret const stripe = new Stripe "sk live 4eC39..." // committed to GitHub. game over. Basic stuff. The kind of thing a junior dev catches in 30 seconds. But you have no junior dev. What I built PushSafe connects to your GitHub repos and automatically reviews every PR you open. Posts inline comments on the diff. Like a teammate who never sleeps.
