Every developer has a graveyard of bookmarked tools:
- One site for JWT decoding
- Another for JSON formatting
- A third for Base64
- A fourth for Regex testing
I got tired of context-switching and built them all into one place:
DevBench
Here are the 5 I use most:
1. JWT Debugger
Paste any token → see header, payload, signature decoded instantly.
Shows expiry in local time, not UTC.
2. JSON Formatter
Validates + formats + highlights exactly where your JSON broke and why.
3. Base64 Encoder/Decoder
Handles both text and file input. Shows byte size before/after.
4. Regex Tester
Live match highlighting with a breakdown of what each part of your
pattern does in plain English.
5. UUID Generator
Generates v4 UUIDs, ULIDs, and NanoIDs — all explained with
use-case differences.
Everything runs in the browser. No login, no data sent anywhere,
works offline after first load.
