Zephium
Zephium is an open-source browser built in Rust that features a canvas where AI agents execute tasks.
Zephium is an open-source browser built in Rust using WebKit on macOS and WebView2 on Windows. It blocks ads and trackers natively, runs Chrome extensions, and includes an AI work environment called Work where agents execute complex tasks in parallel on a visual canvas. Users can describe outcomes in plain words, watch agents browse live pages, and keep results, plans, and documents organized. The browser also includes built-in task management, time tracking, and markdown notes. Users can bring their own API keys for various models or sign in to Zephium AI.
