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

Ricuicui is a desktop web browser that combines everyday browsing with AI assistance and browser-using agents. Its in-page AI can summarize, translate and answer questions about open pages, help complete forms and spreadsheets, and draft replies. Agents can carry out multi-step browser tasks by navigating pages and interacting with controls, while agent teams, A2A connections, webhooks and 13 Model Context Protocol (MCP) tools support automation and connections to other AI tools. Users can run Qwen models locally on a GPU or provide their own keys for Claude, GPT and Mistral. Ricuicui also describes action logging and safeguards intended to prevent AI from entering passwords or payment-card numbers. The browser offers Windows and macOS editions, a free version, and Ricuicui Pro at €12.90 for one year without automatic renewal.
