Hey Product Hunt!
I built DevToys because I was tired of using 15 different ad-filled websites just to format JSON, decode a JWT, or generate a UUID. I wanted a dev toolbox that felt like a native app — instant, clean, and distraction-free.
DevToys has 40 essential tools in one single page. Everything runs client-side, so it's lightning fast. No ads, no sign-ups, no cookie banners.
Just bookmark it and you've got every dev tool you need one click away.
Would love your feedback! What other tools should I add?
Also check out ShrinkRay (file compressor), ConvertIt (file converter), and Cutout (background remover) — same privacy-first model!

finally a swiss army knife i actually want to keep open. the jwt decoder being instant and fully local is genuinely useful, no more pasting tokens into shady websites

the all client side approach is such a thoughtful call, no server round trips just instant tooling right in the browser.
