I built API Vault out of a problem I kept running into while working on side projects. Every time I needed an API, I’d end up opening 10+ tabs — checking if it was free, if it required auth, if CORS worked, or if the API was even still alive. It was messy and time-consuming. So I decided to build a single place where developers can discover, search, filter, and compare 2,300+ free public APIs across 50+ categories without leaving the browser. Some things I added to make it actually useful: • 🔍 Instant search with filters (category, auth type, CORS) • ⚡ API Finder Wizard — answer a few questions and get API suggestions • 📊 Compare up to 4 APIs side-by-side • 📦 Curated API bundles for common projects • 🎯 Integration tips and code snippets on every API page Would love to hear what you think ? Are there any APIs or features you’d want to see added?
