## Introduction
Brave is a Chromium-based web browser that integrates ad and tracker blocking directly into the browser engine. It aims to provide faster page loads and better privacy without requiring third-party extensions, while remaining compatible with the Chrome Web Store ecosystem.

## What Brave Does
- Blocks ads, third-party cookies, and cross-site trackers by default via Brave Shields
- Upgrades connections to HTTPS automatically where possible
- Prevents fingerprinting techniques used to identify users across sites
- Includes a built-in Tor mode for private browsing through the Tor network
- Supports all Chrome extensions through the Chrome Web Store

## Architecture Overview
Brave is built on top of the Chromium engine with a custom content filtering layer called Brave Shields. The ad-blocking engine uses a Rust-based library (adblock-rust) that processes filter lists efficiently. Privacy features like fingerprint randomization and bounce-tracking protection are integrated at the browser level rather than added as extensions, which reduces overhead and improves reliability.

## Self-Hosting & Configuration
- Available as pre-built binaries for Windows, macOS, Linux, Android, and iOS
- On Linux, install via APT, Snap, or Flatpak depending on distribution preference
- Build from source by following the Chromium build instructions with Brave-specific patches
- Configure Shields settings globally or per-site via the address bar shield icon
- Sync bookmarks, settings, and open tabs across devices using an encrypted sync chain

## Key Features
- Blocks ads and trackers at the engine level without needing extensions
- Rust-based ad-blocking engine that is faster than extension-based alternatives
- Built-in Tor integration for anonymous browsing sessions
- Chromium compatibility means full support for Chrome extensions and DevTools
- Reduces page load times and bandwidth usage by eliminating unwanted network requests

## Comparison with Similar Tools
- **Firefox** — Independent engine with strong privacy add-ons; Brave offers ad blocking built-in on a Chromium base
- **Chromium** — The upstream project without Brave's privacy enhancements and ad blocking
- **Vivaldi** — Feature-rich Chromium fork focused on customization; Brave prioritizes privacy and ad blocking
- **LibreWolf** — Privacy-hardened Firefox fork; Brave provides a similar philosophy on the Chromium platform

## FAQ
**Q: Is Brave fully open source?**
A: Yes. The browser source code is available on GitHub under the Mozilla Public License 2.0. Some optional services like Brave Search have separate licensing.

**Q: Does Brave break websites with its ad blocking?**
A: Most sites work correctly with default Shields settings. For sites that break, you can lower the blocking level per-site through the Shields panel.

**Q: Can I use Chrome extensions in Brave?**
A: Yes. Brave supports the Chrome Web Store and is compatible with Chrome extensions.

**Q: Does Brave collect telemetry?**
A: Brave collects minimal anonymous usage statistics that can be disabled in settings. No browsing history or personal data is sent to Brave servers.
