SwiftGear

Offline developer utilities in Chrome's side panel: JSON, Base64, JWT, UUID, hashes, regex and more. Nothing leaves your browser.

SwiftGear All your everyday developer tools in your browser's side panel, and every one of them works offline. Format a JSON response, check the WCAG contrast ratio, decode a JWT, generate a UUID, hash a string, test a regular expression or make a QR code without pasting your data into a website. WHAT IT DOES - Opens in the side panel: click the toolbar button or press Alt+Shift+D. The panel stays open next to the page you are working on. - Search as you type: Enter opens the first match, the arrow keys move through the results and Escape goes back. - Favourites: star the tools you use most and they stay at the top of the list. - Right-click on selected text: send it straight to a matching tool (Format JSON, Check the WCAG contrast ratio, Decode Base64, Encode Base64, Decode JWT, Decode URL, Hash text, Convert timestamp, Make QR code, Format SQL, Explain cron expression, Format XML, Prettify YAML). - A complete User Guide built in, with a page for every tool: its options, its defaults and an example. - Light and dark mode, following your system. PRIVATE BY DESIGN - Everything runs inside your browser. Nothing you type or paste is sent anywhere. - No account, no analytics, no tracking, no advertising. - No access to the websites you visit: SwiftGear only sees the text you select, at the moment you pick an entry from its right-click menu. - Your favourites and settings stay in your browser's own storage for this extension, on this computer only.
