As of 2019, Brave supports Windows, macOS, Linux, Android, and iOS. The current version features five search engines by default, including their partner, DuckDuckGo.[8]

Business modelEdit

Brave uses its Basic Attention Token (BAT) to drive revenue.[9] Originally incorporated in Delaware as Hyperware Labs, Inc in 2015, they later changed their name to Brave Software, Inc. and registered in California, where the company is headquartered.[10]


Brave is developed by Brave Software, which was founded on May 28, 2015, by CEO Brendan Eich and CTO Brian Bondy. On January 20, 2016, Brave Software launched the first version of Brave with an ad blocking feature, and announced plans for a privacy ad feature and a revenue sharing program.[11]

In June 2018, Brave released a pay-to-surf test version of the browser. This version of Brave is preloaded with approximately 250 ads, and sends a detailed log of the user's browsing activity to Brave for the short-term purpose of testing this functionality. Brave announced that expanded trials will follow.[12] Later that month, Brave added support for Tor in its desktop browser's private browsing mode.[13]

Until December 2018, Brave ran on a fork of Electron called Muon which was marketed as a "more secure fork". Nevertheless, Brave developers moved to Chromium citing a need to ease their maintenance burden.[7] The final Muon-based version was released with the intention that it would stop working and instruct users to update as the end of life approached.[14]

In June 2019 Brave started testing new ad-blocking rule matching algorithm implemented in Rust that Brave claims is on average 69 times faster than the previous implementation in C++. The new algorithm is inspired by uBlock Origin and Ghostery algorithms.[15]

Critical receptionEdit

In January 2016, in reaction to Brave Software's initial announcement, Sebastian Anthony of Ars Technica described Brave as a "cash-grab" and a "double dip". Anthony concluded, "Brave is an interesting idea, but generally it's rather frowned upon to stick your own ads in front of someone else's".[16] TechCrunch,[17] Computerworld,[18] and Engadget[19] termed Brave's ad replacement plans "controversial".

In February 2016, Andy Patrizio of Network World reviewed a pre-release version of Brave. Patrizio criticized the browser's feature set as "mighty primitive," but lauded its performance: "Pages load instantly. I can't really benchmark page loads since they happen faster than I can start/stop the stopwatch".[20]

In April 2016, the CEO of the Newspaper Association of America, David Chavern, said that Brave's proposed replacement of advertising "should be viewed as illegal and deceptive by the courts, consumers, and those who value the creation of content".

In April 2017, TechWorld praised Brave's "great speeds and advanced ad-tracking controls", but said that its "extension functionality is still lacking".[21]

Basic Attention TokenEdit

Basic Attention Token Logo

The "Basic Attention Token" (BAT) is an open-source, decentralized ad exchange platform based on Ethereum.[22]

Brave Payments, which formerly used Bitcoin, allows users to tip websites and content creators (such as YouTubers and Twitch streamers)[23] with BAT tokens, akin to patronage services such as Patreon.[24]

Integration of BAT into an application involves implementing BAT Ads, a system that displays ads to users based on locally stored data. Ad targeting is performed locally, removing the need for third-party tracking.[25]

In an initial coin offering on May 31, 2017, BAT sold 1,000,000,000 BAT for a total of 156,250 Ethereum (US$35M) in less than 30 seconds.[22][26] An additional 500,000,000 BAT was retained by the team for developer and user growth pools, which is used to promote the adoption of the platform.[22]

Additionally, they received at least US$7 million in angel investments from venture capital firms, including Peter Thiel's Founders Fund, Propel Venture Partners, Pantera Capital, Foundation Capital, and the Digital Currency Group.[27]

In early December 2017, the development team disbursed the first round of its user growth pool grants. A total of 300,000 BAT was distributed to new users on a first come first served basis.[28][29]
