Why suprow?

🔒 Privacy first, always

Zero cloud sync. Zero telemetry. Passwords encrypted with your system keychain (macOS Keychain / Windows DPAPI). Lock sensitive spaces with a password. Auto-lock after idle. No account required. No data leaves your machine – ever.

🧩 Spaces instead of tabs

Organise your tools into spaces like Work, Personal, Banking. Each space has its own apps, colors and identity. Isolate any space to get separate cookies, logins and storage. Switch with ⌘1–9.

⭐ Quick Access

Pin your most-used sites to the topbar. Hover the star icon and your favorites appear instantly. One click opens, mouse away hides. Zero friction.

🛡️ Built-in Ad Blocker

uBlock Origin ad and tracker blocking out of the box. No extensions needed. Faster page loads, less noise, more focus. Works on YouTube too.

🎹 Keyboard-centric

Terminal-style command palette (⌘T), tab switcher (⌘S), space shortcuts, find-in-page. suprow feels like a window manager for the web.

📐 Adaptive topbar

Three topbar sizes — Compact (36px), Normal (48px), Large (60px). Every element scales proportionally. Your browser, your size.

Local first. No exceptions.

💾 Your data, your disk

All settings, spaces, passwords and history live in a single JSON file on your machine. Export it, back it up, version-control it. You own it completely.

🔐 Encrypted vault

Login credentials are stored in an encrypted local vault (AES-256-GCM) protected by a master password. No cloud vault, no third-party service. Backup and restore your vault anytime.

👻 True incognito

Incognito mode uses a fully isolated session. No cookies persist, no history is saved, no data bleeds between normal and private browsing.

Space Isolation — total separation

In a regular browser, all tabs share the same cookies, logins and storage. Log into Gmail in one tab, and every other tab knows about it.

suprow's Space Isolation gives each workspace its own separate browser profile — own cookies, own cache, own service workers. Like having multiple browsers in one window.

🔐

Isolated sessions Each space gets its own cookie jar. Log into different Google accounts per space.

🔑

Space Lock Password-protect any space. Unlock required on every app restart or after idle timeout.

⏱️

Auto-lock on idle Configure 1–60 min idle timeout. Spaces auto-lock when you step away.

🗑️

Clean delete Delete a space and all its isolated data (cookies, cache, storage) is wiped from disk.
