I Built 87 Free Browser-Based Tools — Here's What I Learned

Why I Built This As developers, we constantly reach for small online tools — format some JSON, test a regex, generate a UUID, compress an image. But each tool is on a different website, many with ads, popups, and dark patterns. I decided to build one site with all of them : ToolPilot . The Rules I Set Everything runs in the browser — no server processing, no data uploads No signup — just open and use No frameworks — pure HTML, CSS, and JavaScript Fast — every tool loads instantly What's Inside (87 tools) Developer Tools JSON Formatter — format, validate, minify Regex Tester — real-time matching with explanation JWT Decoder — decode without sending tokens to a server CSS Flexbox Generator — visual flexbox builder CSS Grid Generator — visual grid layout builder Diff Checker — compare text side by side Image Tools Image Compressor — compress without uploading Image Resizer — resize with presets for social media SVG to PNG — convert with custom dimensions Security Tools Password Generator
