Overview

One popup, five tools. 100% offline — your tokens never leave the browser.

Five essential developer tools in one clean popup. Stop pasting sensitive tokens into random online converters. DevBox does everything locally, so your data never touches a server. WHAT IT DOES - Base64: encode and decode text in a click - JWT: inspect and decode JSON Web Tokens instantly - URL: encode and decode URL components safely - Hash: generate hashes for quick checks and comparisons - JSON: format, validate, and minify messy JSON PRIVATE BY DESIGN 100% offline. There is no account, no login, and no tracking. Every conversion runs inside your browser, so your tokens, payloads, and secrets never leave your machine. Permissions: - storage: remembers your preferences and last-used tool between sessions. - contextMenus: adds right-click shortcuts to encode or decode selected text. - activeTab: reads text you select on the current page when you invoke a tool. - clipboardWrite: lets you copy results back to your clipboard in one click. - alarms: schedules lightweight background cleanup tasks.
