DeepSeek Harness Studio

DeepSeek Harness Studio wraps DeepSeek Harness's web workspace in an Electron desktop app, with the desktop process starting and managing a local dsh web service so no command line is needed to search for, verify, install, enable, disable or uninstall plugins. It discovers and recommends ecosystem plugins automatically, checks a plugin's version, permissions, compatibility and risk before installing it, and rolls back unfinished installs automatically, falling back to a safe mode that only allows disabling or uninstalling when its plugin list becomes inconsistent.

It organizes local projects into workspaces with searchable, renameable, archivable and forkable sessions, a session-wide table of contents for long conversations, a preset marketplace with seven built-in workflows, planning tools such as Plan, Goal, Todo and Jobs, sub-agent creation with parent-child session navigation, and configurable read-only, workspace-write or full-access permissions with explicit confirmation for risky actions.

It connects to DeepSeek and other compatible providers, including local inference through Ollama, vLLM, SGLang or a custom OpenAI-compatible endpoint, and ships as macOS arm64 and Windows x64 preview builds distributed only through its own GitHub Releases.
