About
Kitesurf is an agent-first browser built specifically for AI agents and runs entirely on Cloudflare Workers instead of using Chromium. It is designed around what agents actually need: structured machine-readable content, scalable execution, low CPU and memory use, and safe interaction with untrusted web pages, rather than human-facing features such as tabs, themes, extensions, or pixel-perfect scrolling. Each page load is treated as untrusted input, every session starts fresh, and components are isolated with access only to the resources required for their function. Kitesurf uses native Rust compiled to WebAssembly where possible and is organized around an Engine, PageScript, and PageRenderer. The Engine exposes Chrome DevTools Protocol WebSocket and REST APIs and stores session state, while PageScript parses HTML and CSS and runs JavaScript and WebAssembly inside isolated Workers.

About
Project Solara is Microsoft’s early chip-to-cloud platform for agent-first devices, built to support a future where agents are easy to reach, naturally engaged, and always available across new device form factors. Instead of centering the experience around traditional apps, Project Solara is designed for an open, multi-agent world where specialized agents can be built, deployed, and experienced across every layer of the stack. Microsoft imagines a diverse ecosystem of agent-first devices, from small to large, fixed to hypermobile, and personal to professional, each supported by a base OS, shell, developer ecosystem, apps, web-based intermediation, and silicon integration. It is designed to make agents more capable and accessible by composing hardware, software, cloud services, and developer tools into a foundation for new interaction patterns. Project Solara includes two concept devices that show how agent-first computing could work in practice.
