qr-api generates QR codes on demand. Send a GET request with any text, get back a ready-to-use PNG — no library to install, no encoder to maintain. $10/month, unlimited requests, no rate limits.
Built with Node.js, Express, Postgres, deployed on Railway with Stripe billing. This is my first project ever — went from never using git to a live paid product in two sessions, mistakes and all.
Would love feedback on pricing and positioning!
