DevsTools is a free, no-login toolbox with 27+ developer utilities in one place. Format/validate JSON, encode/decode Base64, generate UUIDs, build QR codes, run regex tests, and create MD5/SHA hashes—fast and client-side, so your data never leaves the browser. Built for speed with a clean UI, works on desktop/mobile, and new tools are added regularly to cover daily dev needs

We built DevsTools as a free, no-login toolbox with 27+ utilities in one place—JSON format/validate, Base64 encode/decode, UUIDs, QR codes, regex tests, MD5/SHA hashes, and more. It’s fast, client-side (your data stays in the browser), clean UI, works great on desktop/mobile, and we keep adding tools. Would love your feedback on what to ship next!
