Disclosure: I built it. I am a solo indie dev. Revenue so far: zero. It went live this week.
Backstory. I used to be a CIO. Checking if a website was really healthy took most of a day. Domain expiry, certificates, DNS, mail authentication, what a page actually does in a browser, what it loads before the visitor agrees to anything. Nobody ever had that day, so it did not get done.
I wanted the tool for myself. Then I saw who else wants it: agencies and freelancers. A report like this helps them win a client, and then keep one.
Stack. Java 25 and Spring Boot 4 for the engine. Postgres. Selenium driving Chromium for the browser part. React and TanStack on the front end. One VPS I manage myself. No third party API does the checking. Every check runs against public records and the site itself.
Try it. No account needed. Paste a domain and you get 118 of the 134 checks in about three seconds. finetooth.net
What I want from you: tell me what it gets wrong. A check that fires when it should not is worth more to me than a compliment. Roast the landing page too. I have read it too many times to see it.
