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

Modsurfer provides ops & dev teams with the first system-of-record and diagnostics application to search, browse, validate, audit, and investigate WebAssembly binaries. At-a-glance insights into WebAssembly module data (code size & complexity, imports/exports & more). Search for details about modules (hash, ID, function names, strings, namespaces, errors & more). Easily audit and track all the WebAssembly code in your stack. Debug & triage issues otherwise difficult to pinpoint in opaque WebAssembly format. Write or generate a "check file" to track binary requirements. If a module fails validation, a helpful report is created to get things back on track. Validate your modules for import/export existence, function signature, security compliance, runtime complexity, & more. The CLI puts all your Modsurfer data at your fingertips and is the easiest way to interact with the Modsurfer desktop or enterprise server.
