Developer tools

devkit

8 tools · offline-first · no sign-up

Tools that work. Nothing else. Fast, offline-first developer utilities — format JSON, decode JWTs, test regex, all in the browser.

The problem

Every developer has the same ten tabs open for the same ten utilities — formatters, decoders, regex testers. Most of those sites are ad-supported, run slow, and stop working when the wifi flakes mid-flight.

What we built

devkit is a single fast site with the eight utilities developers reach for most. JSON formatting, JWT decoding, regex testing, UUID generation, Base64, hashing, URL encoding, and text diffing — all offline-capable and free of trackers.

  • JSON Formatter, JWT Decoder, Regex Tester, UUID Generator
  • Base64 Codec, Hash Generator, URL Encoder, Text Diff
  • Offline-first — works without a network connection
  • No sign-up, no tracking, no fluff

What's live

  • 8 developer tools (JSON Formatter, JWT Decoder, Regex Tester, UUID Generator, Base64 Codec, Hash Generator, URL Encoder, Text Diff)
  • Offline-first architecture — works without a connection
