DevTab
110+ dev tools. One tab. Zero server calls.
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.
