DevDock
Your daily dev toolkit, one keyboard shortcut away
19 essential developer tools in a Chrome side panel — JSON Formatter, JWT Decoder, Base64, Regex Tester, Diff Checker, UUID Generator, Cron Builder, and more. No more juggling bookmarks or hopping between jsonformatter.org, jwt.io, and diffchecker.com. Everything runs offline in your browser, no data leaves your machine, no accounts. Toggle with Ctrl+Shift+D. Free forever, open source utility lib.
I built DevDock because I got tired of having jsonformatter.org, jwt.io, diffchecker.com, base64encode.org, and a dozen other single-purpose tabs open while debugging.
Every backend dev I know does the same thing — paste a JWT into jwt.io to inspect a token, paste a response into jsonformatter to read it, paste two configs into diffchecker. It's all the same workflow: copy, switch tab, paste, read, switch back.
So I bundled the 19 tools I reach for daily into a Chrome side panel that opens with Ctrl+Shift+D.
What's inside:
– Encode/decode: JWT, Base64, URL, HTML entities
– Format: JSON, regex, diff, YAML↔JSON, markdown
– Generate: UUID, hashes (MD5/SHA), cron, passwords
– Transform: timestamps, case, timezones
Everything runs entirely in your browser — no servers, no API calls, no data leaves your machine. So you can paste production JWTs, internal JSON, secrets — none of it goes anywhere.
The utility library is open source on GitHub if anyone wants to use the formatters/decoders in their own projects.
Free forever, no accounts, no upsells.
Would love feedback — especially on which tools to add next. V2 already has cron builder and YAML↔JSON, working on what's next.
