110 free developer tools that run entirely in your browser — JSON formatter, JWT decoder, regex tester, base64, diff checker, SQL formatter, and 100+ more. No uploads. No server. No signup.
Hey PH! 👋
Every dev tool lives on a different website.
jwt.io for JWT decoding. regex101 for regex. Some random site for JSON formatting. Another for diff checking. Another for curl → code.
10 bookmarks. 10 different UIs. 10 different servers that just received your API keys, tokens and .env files — and you never know where that data goes.
So I built DevTab — one place for all of it, with zero network calls.
Everything runs 100% in your browser. Open DevTools → Network while using it. Nothing fires. Your data never leaves your tab.
110+ tools so far:
→ JWT decoder
→ JSON formatter & validator
→ Regex tester
→ Diff checker
→ curl → code
→ SQL formatter
→ .env diff checker
→ Chmod calculator
→ Color converter
→ HTTP status codes
→ + more added every week
Free forever. No signup. No uploads. Ever.

Been looking for a quick JWT decoder without the usual upload-to-server nonsense, and this nailed it. The regex tester was a nice bonus I wasn't expecting to actually use.
How do you keep all 110 tools updated when browser standards or new dev formats shift, and is there any plan to add team sharing or sync for saved snippets?
would love a way to save my frequently used tools as a custom sidebar, plus maybe a quick keyboard shortcut to jump between tools. also adding a dark/light theme toggle would be nice since some of these visual tools are easier on the eyes in dark mode
How do you handle tools that usually need to call an external API, like an OpenAPI tester or anything that hits a real endpoint, since everything runs purely client-side?
How do you handle really large files like massive JSON payloads, does it still stay snappy or does the browser start to choke at a certain size?
