About

Flue is an open agent framework for building durable AI agents with a programmable TypeScript harness. Created by the team behind Astro, it uses a React-like hooks API to compose agent behavior, persistent state, lifecycle events, models, tools, sandboxes, subagents, skills, and MCP servers in code. Agents are stateful and addressable over HTTP, keep context across conversations and events, and can change capabilities as work progresses. Flue records every session in a durable stream, so accepted work survives crashes, restarts, and deploys; interrupted sessions resume automatically and clients reconnect without starting over. Developers can run agents locally, in CI, from their own backend, or orchestrate them with systems such as Cloudflare Workflows and Inngest. Secure sandboxes let agents run commands, edit files, and do real work, while tools connect them to APIs and data. Flue is powered by Pi and supports different LLM providers, allowing teams to choose the models they want.

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.
