About DeepSeek Harness (DSH)
DeepSeek Harness (DSH) is an open-source agent framework released by DeepSeek in August 2026. Its core concept is that every tool, capability, and integration is implemented as an npm plugin rather than being built into the core system. This plugin-based architecture allows users to add only the functionality they need, reducing bloat and enabling customization. DSH is positioned as an alternative to proprietary agent frameworks like Claude Code, offering an open-source option with community-driven extensions. The framework supports both headless and web-based agent operations, with a verification process that tests plugin installation, loading, and execution before marking them as verified. Users interact with DSH through a web interface, configuring models, workspaces, and tasks via a local server running on port 3080. The project includes a growing directory of over 7,794 plugins, with 2,033 verified through a multi-level testing process that includes live execution checks.
