Prosto Browser Interface
Tab dockSwipe up

Tabs live where your thumb already is.

The floating dock is the whole browser. It sits in the bottom third of the screen, inside the natural arc of your thumb, and keeps every frequent action one gesture away.

  • Swipe up. Start searching.

    01

    A short upward flick from anywhere on the dock opens a new tab and puts the cursor in the search field.

  • Tabs, not tab hunts.

    02

    Every open page stays visible in the dock. Tap to switch, drag to reorder, swipe to dismiss.

  • It gets out of the way.

    03

    The dock recedes as you read and returns the instant you scroll back up. No top bars, ever.

Thumb gestures in action. Swipe upward from anywhere on the dock to open quick search without reaching for the top of your screen.

The internet,with the noise turned down.

Ad and tracker blocking is not an extension. It is the engine. Prosto filters requests inside the browser, keeps pages intact, and never asks you to trust a black box.

EasyList, built in

Ads and trackers are matched against bundled EasyList rulesets before a request leaves the app.

Pages still work

Blocked images get a transparent pixel, beacons get a 204, and scripts receive benign stand-ins.

Nothing phones home

No analytics SDK. No telemetry. No account. Your tabs, history, and engines stay on your device.

Small by design.Fast by default.

Prosto uses the WebView already on your phone instead of shipping another Chromium. The result is a browser that opens instantly and stays out of your RAM.

Scroll down and the dock recedes. Scroll up and it is back before you notice.

Your WebView, ready to browse.

No bundled engine. Prosto reuses the WebView on your phone with pooled tabs and crash recovery.
