deer-flow is an open-source long-horizon SuperAgent harness from ByteDance that researches, codes, and creates. It combines sandboxes, memories, tools, skills, subagents, and a message gateway to run tasks lasting minutes to hours.

You want a ready-made multi-agent harness for extended research, coding, and content-generation tasks rather than assembling one yourself.

Use it to

  • Run long-horizon deep research tasks
  • Delegate multi-step coding work to subagents
  • Generate content such as podcasts
  • Extend the harness with custom tools and skills
  • Study a LangGraph/LangChain-based agent architecture

For Developers building long-running agentic applications
