AnterSurf
The most private browser ever built.
Zero telemetry · Zero tracking · Zero compromise
SCROLL
AnterSurf was built from zero for one purpose: absolute privacy. Every byte stays on your machine. No exceptions. No asterisks. No "opt-out" buried in settings nobody reads.
No analytics, no crash reports, no phone-home. AnterSurf sends exactly zero bytes to anyone. Ever.
We don't collect, store, sell, or access your browsing data. Not now. Not ever. There's nothing to collect.
No sign-up. No sync. No cloud. No "Sign in with Google." Your browser doesn't need to know who you are.
Built on Electron with minimal overhead. No background services, no telemetry daemons, no crypto miners.
Built-in AnterGet handles all downloads with pause, resume, speed control, and progress tracking.
All data in local SQLite. Bookmarks, history, settings, sessions — yours, on your disk, nowhere else.
Security Architecture
AnterSurf never sends tracking headers, fingerprinting signals, or unique identifiers. Your browsing sessions are invisible.
All your data — bookmarks, history, sessions — is stored locally in an encrypted SQLite database. No cloud sync means no cloud breach.
When you're browsing a page, AnterSurf itself makes zero background requests. No update checks. No DNS prefetching. No safe browsing API calls with your IP.
All downloads are handled through AnterGet, our built-in download manager. Files go directly to your machine. No cloud intermediary.
About
AnterSurf is the most private desktop browser ever built. Not "privacy-focused." Not "privacy-friendly." The most private. Full stop.
Most browsers are built around advertising. They track you, profile you, and sell your attention. AnterSurf was built around the radical idea that a browser should just be a browser — a tool you control, not a platform that controls you.
Every feature in AnterSurf was designed with one question: does this serve the user, or does this serve us? If it doesn't serve the user, it doesn't ship.
Chrome tracks you. Firefox phones home. Safari sends telemetry to Apple. Edge is Microsoft's advertising vector. Opera is owned by a Chinese consortium. Every major browser has a conflict of interest.
AnterSurf has no advertisers to please. No shareholders demanding engagement metrics. No product team optimizing for data harvesting. Just a browser that works for you, and only you.
Version 26.1 "Cosmo Atlas" adds tab favicons, pinning, mute, per-tab dark mode, context menus, drag-reorder, built-in download manager, and a Chromium-grade interface — all without compromising a single byte of your privacy.
Architecture
Built on Chromium with full process isolation. Sandboxed rendering, GPU acceleration, and modern web standards.
All persistent data in a single local SQLite file. No JSON dumps, no IndexedDB, no cloud-backed storage.
Curl-based download manager with pause, resume, progress tracking, and speed display. No third-party services.
Full session persistence. Close and reopen exactly where you left off. No account sync needed.
Each tab is an isolated webview. Separate process, separate session, separate memory space.
The browser itself never phones home. No update checks, no telemetry, no DNS prefetching in the background.
