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

Lightpanda is an open source headless web browser designed specifically for AI systems and large-scale web automation workloads. Unlike traditional browsers such as Chrome or Firefox that are built primarily for human interaction and graphical rendering, Lightpanda is engineered from the ground up for machines and automated processes. It runs without a graphical interface and focuses only on the components required for programmatic web interaction, such as HTML parsing, DOM tree construction, and JavaScript execution. By eliminating visual rendering tasks like layout calculations, image loading, and pixel painting, the system dramatically reduces resource usage and improves performance for automation tasks. Lightpanda was built from scratch using the Zig programming language rather than modifying an existing browser engine, allowing it to be optimized for speed, reliability, and minimal memory consumption.
