BrowserDock — Developer Tools

A handy set of developer tools that open in your browser sidebar and run entirely on your device, so your data stays private.

BrowserDock brings a collection of everyday developer utilities into your Chrome sidebar, so you can work with them right next to whatever page you happen to be on. There are no tab switches, no sign-ups, and nothing ever leaves your computer. What you can do with BrowserDock You can clean up and check structured data with the JSON formatter, which formats, validates, and minifies your input. When you need to work with encoded text, the Base64 tool converts text to and from Base64 with full Unicode support, and the URL tool handles percent-encoding for addresses and query parameters. For working with tokens, the JWT decoder lets you inspect the header, payload, and expiry information inside a JSON Web Token. The hash tool produces MD5, SHA-1, SHA-256, and SHA-512 digests from any text. When you need identifiers or credentials, you can create version 4 UUIDs in bulk, and build strong random passwords with rules you control. Your data stays on your device Every tool runs locally in your browser. BrowserDock has no backend server, makes no network requests, and includes no analytics or tracking of any kind. Anything you type or paste stays in your browser's memory and is gone once you close the panel. Because everything runs on your machine, the extension also works without an internet connection. Why developers like it BrowserDock is lightweight, loads instantly, and gives you results without spinners or loading screens. It opens in the sidebar so it stays out of your way while remaining one click from whatever you are doing. It follows your system's light or dark theme, requires no account, and is free to use. Whether you are debugging an API response, checking a token from your authentication flow, generating test identifiers, or creating a secure password, BrowserDock keeps the tools you reach for most within easy reach.
