xueboyang1985 Posted on May 31 I Built 24 Free Browser Tools in 6 Weeks — Here's What I'd Do Differently # webdev # javascript # indiehackers # startup Six weeks ago, I had zero browser tools. Now I have 24. Revenue: $0. This is not a success story. It's a reality check on what happens when you focus on building and ignore distribution. What I Built 24 tools, each a single HTML file with vanilla JavaScript. Hosted on GitHub Pages. No server, no database, no frameworks. Hub: 24 Free Browser Tools The tools span four categories: PDF & Document: Merge, split, convert, extract — 7 PDF tools Image: Compress, resize, crop, AI background remover, color picker Developer: JSON-CSV converter, text diff, base64 encoder, UUID generator, markdown editor Productivity: Password generator, QR codes, timestamp converter, case converter, word counter All running client-side. Your files never leave your browser. What Went Right 1. Single HTML File Architecture No build step. No npm install. No node_modules . Each tool is one file: <!DOCTYPE html> <html> <head> <style> /* all CSS inline */ </style> </head> <body> <!-- all HTML --> <script> // all JavaScript </script> </body> </html> Enter fullscreen mode Exit fullscreen mode This means: instant deploys, zero dependencies, trivially auditable. Users can view source and confirm nothing shady is happening. 2. Browser APIs Are Incredible Now Canvas API — Image compression, resize, crop. All at native speed. Web Crypto API — crypto.getRandomValues() for true-random UUIDs and passwords. WebAssembly — Runs a full AI neural network for background removal. ~5 seconds per image, no cloud GPU. EyeDropper API — Pick any color from your screen. I didn't need a single server-side dependency. The browser IS the platform. 3. Free Hosting That Scales GitHub Pages: free, global CDN, auto-deploys on git push . Even if 100,000 people use a tool simultaneously, GitHub's CDN
