BrowserBox by DOSAYGO

Secure, modern Remote Browser Isolation (RBI) with a clientless experience

🖥️ NEW in v18.10.0 — the BrowserBox desktop app ^BETA

BrowserBox now ships with a desktop app for running your BrowserBox without the command line.
Start and stop sessions, pick how people reach it (Cloudflare, ngrok, Tor, ZeroTier or direct), copy the login link,
manage browser policy, and run any bbx command from a form, with live progress and the full output a click away.
On Linux hosts, the Fleet dashboard shows your whole seat pool at a glance: capacity, routes, health checks, and one-click actions per seat.

Open it with bbx gui. The app comes inside the BrowserBox binary you already installed, so there is nothing extra to download.
It installs for your user on first run and prints where it lives, so you can pin it to your Dock, Start menu or desktop.
Signed and notarized on macOS, signed on Windows, and available on Linux desktops (X11).

_{Beta: the desktop app is new and still evolving. The bbx command line remains the complete, supported interface. Please tell us what works and what doesn't.}

🔐 NEW in v18.0.1 — Passkey authentication on macOS: sign in to websites with real passkeys inside your remote browser.
Passkeys are created and stored on your Mac's Secure Enclave and unlocked with Touch ID via the BrowserBox Passkeys helper — a small signed & notarized app that BrowserBox prompts you to download when a site requests a passkey. Your keys never leave your device.

💻 Try it in your terminal — access BrowserBox over SSH via KRNL:

Notice: Legacy source code removed (March 2026)

When BrowserBox transitioned to a binary distribution model in late 2025, we retained legacy source code in this repository for a six-month period to give existing customers time to migrate. That period is now over and all legacy source has been removed.

Current BrowserBox source is private and proprietary. It diverges significantly from the legacy code that was previously housed here -- by over 1,000 commits -- with extensive bug fixes, security hardening, and performance enhancements that are absent from the legacy codebase and any forks thereof.

Legacy source code may still be visible in third-party forks as a historical curiosity. That code is not open source. Permission is not granted to use that source in your products, to train AI models, or to re-implement BrowserBox functionality from it. These acts violate BrowserBox terms. See LICENSE.md and TRADEMARK.md.

Current source is available to customers above a threshold ACV as part of due diligence, on request. Contact [email protected].
