JezView — Responsive Viewport Browser

Viewports

Zoom — 65%

Proxy mode

Loads pages through the JezView proxy: unblocks sites that refuse to be framed, and phones/tablets get a real mobile user-agent — the server responds as it would to the actual device.

Sync scrolling & clicks

Viewports scroll together, and a link clicked in one device navigates all of them. Needs Proxy mode on.

Engine mode (Jezweb devs)

Each viewport becomes a REAL Chromium page with engine-level device emulation (true DPR, touch, per-request UA — same as the desktop app), streamed live. Interactive: click, scroll and type in the tiles. Requires a render node: cd cloud && npm start.

Quick presets

Tip: device widths render at true CSS pixels (sites respond as on the real device), then scale to fit via Zoom. If a site refuses to load (blank frame), turn on Proxy mode above — or use the JezView desktop app for full engine-level emulation. ⎙ Screenshot captures all viewports at once via screen capture — pick “This Tab” when prompted.
