Hi Product Hunt. We're Milo Kits, and this is Milo's Launch Check, a free Chrome extension. If you've built an app with Lovable, Bolt, Replit, Cursor or v0, there are things anyone can see on the live site that are easy to miss: a secret key in your JavaScript, a deployed .env file, public source maps, missing security headers. Open your site, click the icon, tick "I own this site", and you get a short list of what's fine and what needs a fix. Each fix is a few plain words you can paste into your AI builder. What it doesn't do: it doesn't log in, submit forms or attack anything. It only makes the same plain requests a visitor's browser makes, without your cookies. There's no tracking, and nothing is sent to us. Privacy policy: https://milokits.com/launch-chec... It's a passive check of public responses, so it can't see your database rules or anything behind a login, and a clean result doesn't mean the app is secure. We're new, with no customers yet, so honest feedback helps a lot. What did it flag on your app, and was anything confusing?
