About

Pixefy helps you spot layout issues instantly and fine-tune designs with live editing tools – right as you build.
It simplifies responsive testing by letting you preview, debug, and edit across multiple screen sizes in one place – no more switching tabs or resizing windows manually.

🚀 Key Features:

✔️ 🟢🟠 Live Responsive Previews – Test across multiple screen sizes side-by-side. Scroll, click, and interact on all screens simultaneously. Match real devices with optional browser bars + native UI spacing.
✔️ 🟠 Custom Screens & Presets – Create and save your own breakpoints, or use popular device resolutions out of the box.
✔️ 🟢 Screen Management – Rearrange, stack (horizontal/vertical), rotate, or zoom screens globally for a flexible workspace.
✔️ 🟢🟠 Inspect & X-Ray – Inspect styles, edit attributes live, and debug layouts with Visual Box Model, grids, and X-Ray overlays.
✔️ 🟢🟠 CSS Debugging Tools – View/edit computed styles, measure distances between elements, compare two elements, and track all changes in the Activity Tab.
✔️ 🟠 Content Editing – Instantly replace text or images, and check word/character counts directly on the page.
✔️ 🟠 Asset Downloads – Extract SVGs, PNGs, and other assets directly from Inspect Tool tabs.
✔️ 🟢 Screenshots & Annotations – Capture full pages, visible areas, or selected regions, then add notes, arrows, and highlights for clear, shareable feedback.
