For the first time since Netscape pioneered the web in 1994, AI gives us the chance to completely reimagine the browser. We've seen tools like Cursor deliver 10x productivity gains for developers—yet everyday browsing remains frustratingly archaic.
You're likely juggling 70+ tabs, battling your browser instead of having it assist you. Routine tasks, like ordering something from amazon or filling a form should be handled seamlessly by AI agents.
At BrowserOS, we're convinced that AI should empower you by automating tasks locally and securely—keeping your data private. We are building the best browser for this future!
vs Chrome
While we're grateful for Google open-sourcing Chromium, but Chrome hasn't evolved much in 10 years. No AI features, no automation, no MCP support.
vs Brave
We love what Brave started, but they've spread themselves too thin with crypto, search, VPNs. We're laser-focused on AI-powered browsing.
vs Arc/Dia
Many loved Arc, but it was closed source. When they abandoned users, there was no recourse. We're 100% open source - fork it anytime!
vs Perplexity Comet
They're a search/ad company. Your browser history becomes their product. We keep everything local.
vs ChatGPT Atlas
Your browsing data could be used for ads or to train their models. We keep your history and agent interactions strictly local.
We'd love your help making BrowserOS better!
BrowserOS is open source under the AGPL-3.0 license.
