NexusLabs DevKit — 8+ Developer Tools

Description

8 essential developer utilities in one popup — format, encode, decode, hash, and validate without leaving your tab. Fully offline. Stop juggling browser tabs for basic dev tasks. NexusLabs DevKit puts 8 powerful, privacy-first developer utilities into a single beautiful popup — right in your browser toolbar. Whether you need to quickly format a messy block of structured data, encode or decode a string, generate a unique identifier, or test a pattern against sample text — DevKit handles it in one click without leaving your current tab. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ What You Can Do Paste in messy structured data and instantly format it with proper indentation, or minify it down to a single line. Built-in validation catches syntax errors and shows clear messages so you can fix problems fast. Need to encode or decode a string? The converter handles that in both directions with one-click copy. The same goes for URL components — percent-encode special characters or decode them back to readable text. Generate cryptographic hashes (SHA-1 through SHA-512) for verifying file integrity or creating checksums — all computed locally using the Web Crypto API. You can also generate unique identifiers one at a time or in bulk. Test your patterns against sample text with live match highlighting, flag support, and group capture display. When you need to switch text between naming conventions like camelCase, snake_case, or kebab-case, the built-in converter handles it instantly. Working with authentication tokens? Decode them right in the popup to inspect the header and payload separately, and check when they expire — no server round-trip needed. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 Privacy First This extension makes zero network requests. Everything runs 100% locally in your browser. There are no analytics, no trackers, and no data is saved, cached, or persisted. It requests no special permissions and has zero access to your browsing history, tabs, or bookmarks. The full source code is available on GitHub. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎨 Designed for Daily Use The interface uses a modern dark theme with a clean tabbed layout. Switch between tools instantly, and everything works at any zoom level with smooth animations and visual feedback. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ NexusLabs DevKit is part of the NexusLabs extension family.
