Why I Built API Finder
Venelin K.
Hey, I'm a developer who's spent way too much time searching through documentation, blog posts, and bookmarks just to find the right API. After years of collecting links and forgetting where I saw that one API, I decided to create API Finder.
This platform is my solution. It's a curated directory where developers can discover, compare, and choose the best APIs for their projects.
I built this for developers like us who value their time and want to focus on building great products.
