# DeerFlow

> Open-source long-horizon agent harness with Docker sandboxes, memory, and sub-agents

DeerFlow is ByteDance's open-source autonomous agent harness built to execute long-running tasks spanning minutes to hours. It pairs a lead agent with parallel sub-agents inside isolated Docker sandboxes featuring full filesystem access, cross-session memory, and progressive skill loading. It works across major LLM providers including Claude, GPT-4, Gemini, DeepSeek, and local models via Ollama.
