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.
