I'm a frontend tech lead by day, and in my spare time (nights/weekends) I've been building DX Toolkit π β a free Chrome extension that drops a floating panel into any tab with the tools I kept wishing were built into the browser.
No ads, no marketing budget, just sharing on LinkedIn and with friends β and somehow it's sitting at 271 installs, only 13 uninstalls, and 34 weekly active users. Not huge numbers, but enough that I think it's worth putting in front of people who actually live in dev tools all day.
What's in it (12 modules so far):
- Storage Scout β browse/edit localStorage, sessionStorage, cookies, and IndexedDB, with a per-site usage breakdown
- Swagger Seeker β filter OpenAPI/Swagger UIs by keyword or HTTP method, download the raw spec
- Viewport Viewer β realistic device mockups (phone/tablet/4K/8K TV) that preserve scroll + form state when switching
- Routing Report β SPA navigation history (pushState, params, query, timing)
- Palette Probe β scan and live-edit a page's CSS custom properties
- Outline Hunter, Vision Validator (color blindness/low-vision simulation), Super Search, PERT Planner, and many mooore! π
Why it might earn your trust, not just your install:
- Manifest V3, content-script only β no background service worker, no remote calls
- Only requests the storage permission, nothing else
- No analytics, no tracking, fully client-side
Genuinely here for criticism as much as praise β what's missing, what's redundant, what would make you uninstall it on the spot.
Search for DX Toolkit on Chrome Web Store or (if you trust me) just click the link Chromewebstore. Thank you for your time π
