About

DeerFlow started as ByteDance's deep-research framework and was rebuilt for 2.0 as a general agent harness: the lead agent decomposes work, delegates to subagents only when parallelism or context isolation pays, and verifies their structured results. Skills provide progressive-loading capabilities (research, slides, web pages), memory persists across sessions, and sandbox modes range from local processes to Docker, Kubernetes, and E2B. An extension API exposes task-lifecycle hooks and middleware, and the gateway reaches IM channels from Telegram to DingTalk. Teams use it as a self-hosted agent platform where they control models — Doubao-Seed-2.0-Code, DeepSeek, Kimi — and data.
