I built 42 browser-based dev tools — here's what I learned

I got tired of bouncing between 10+ sites for simple dev tasks — format JSON, test regex, decode JWTs, check headers, convert data. So I built ToolCrux — 42 browser-based developer tools in one place. No accounts. No frameworks. Most tools run entirely client-side — nothing leaves your machine. A few features (DNS lookup, shareable links, embeds) use Cloudflare Workers at the edge. What makes it different Runs in your browser — no data sent anywhere for most tools Tool chaining — output from one tool flows into the next, no copy-paste Shareable state — every tool can generate a short URL with its exact state Embeddable widgets — drop any tool into your blog or docs with one iframe Core tools JSON Formatter — tree view, JSONPath queries, TypeScript type generation Regex Tester — live match highlighting, named groups, pattern library Password Generator — entropy meter, breach check via HaveIBeenPwned, bulk generation Image Compressor — AVIF/WebP output, before/after slider, EXIF viewer A
