I'm Ashish, and I built DevSpeedTools because I was tired of juggling 15 different browser tabs just to convert YAML to JSON, decode a JWT, or format some messy JSON. Every developer tool I found either: - Required signing up for an account - Uploaded my data to some mystery server - Had ads everywhere - Was painfully slow So I built 60+ developer tools that run entirely in your browser. Nothing you paste is ever sent to a server. You can verify this yourself by opening DevTools → Network tab — zero requests carrying your data. What makes it different: - 🔒 100% private — all processing happens client-side - ⚡ Instant — no server round-trips, results in milliseconds - 🌐 8 languages — EN, ES, FR, DE, JA, PT, KO, IT - 📱 Works offline — once loaded, no internet needed - 💰 Free forever — no freemium, no feature gating Tools include: YAML↔JSON, JWT decoder, Base64 encoder, regex tester, password generator, cron expression builder, markdown converter, and 50+ more. I'd love to hear what tools you'd want added next. Thanks for checking it out!
