Flue is an open-source TypeScript framework for building autonomous AI agents using a React-like hooks API ('use agent' directive, useModel, useTool, useSandbox). It provides durable sessions, sandboxed execution environments, tools, skills, subagents, and deploys to Node.js, Cloudflare Workers, or other runtimes.

Use cases

  • build autonomous coding agents in typescript
  • create ai agents that run tools in a sandbox
  • deploy durable ai agents to cloudflare workers
  • build multi-agent systems with subagent delegation
  • connect ai agents to slack or discord
  • run llm agents with durable session recovery
  • give agents filesystem and shell access safely

When to choose

  • you want a code-first, hooks-based framework for autonomous agents in TypeScript
  • you need durable, resumable agent sessions that survive failures and restarts
  • you want sandboxed execution (local, container, or cloud providers like E2B/Modal) for agent actions
  • you plan to deploy agents to Node.js, Cloudflare Workers, or CI environments
  • you want built-in support for tools, skills, subagents, and MCP servers

When to avoid

  • you only need simple chatbot-style LLM API calls without autonomy or tool use
  • your stack is Python-based (e.g., LangChain, CrewAI ecosystems)
  • you need a no-code or low-code agent builder
  • you require a mature, long-proven framework — Flue is young and evolving rapidly
