In 2008, building SaaS for API's took a few weeks to months. Have you built any tools in just a few hours?

Now. . it took me 5 hours

I built an API to extract RDFa, json-ld, microdata and opengraph from any URL

Build the API - 3 hours
Hosted at aws lambda - 1 hour
Added into RapidAPI's marketplace - 45 minutes
Created google ads - 10 minutes
Create a landing page - card- 10 minutes

It's a 5-hour product. 😍

Have you built any tools in just a few hours? Please share your experience.
