# DeepSeek Harness Open-Sourced: MIT-Licensed Agent Framework Where Everything Is a Plugin

> DeepSeek has open-sourced Harness, a developer-preview agent framework released under a permissive MIT license, and it went viral fast: roughly 95,000 GitHub stars and nearly 9,000 forks in about two days, which DeepSeek claims is the quickest adoption curve GitHub has recorded for a developer tool. The design idea is modularity taken to an extreme. Models, tools, skills, sessions, storage, and even the control loops are all treated as swappable plugins, so the framework is provider-agnostic and works with Claude Code, Codex, OpenAI, Anthropic, Bedrock, and Azure. It can even orchestrate other coding agents as sub-components inside a DeepSeek workflow. The bigger signal is commoditization. As the scaffolding around models becomes free, open, and interchangeable, the value shifts away from any single vendor's agent and toward whoever can wire the pieces together best. An MIT-licensed framework racking up stars this quickly shows how eager developers are to avoid lock-in.
