DeepSeek Harness Adds Windows, macOS Preview

Desktop packaging removes much of the CLI setup friction around DeepSeek Harness, but unsigned installers and a still-changing plugin surface make this better suited to early adopters than production teams.

• –Bundled runtimes let developers launch the Harness web experience without separately installing Node.js or configuring a local server.
• –Windows x64 and Apple Silicon macOS are covered, while broader platform support remains unclear.
• –Users must provide their own DeepSeek API credentials; the desktop app does not include model access or usage credits.
• –Unsigned builds trigger Windows SmartScreen and macOS Gatekeeper warnings, adding trust and distribution friction.
• –The missing persistent-terminal backend limits the desktop build compared with the full CLI experience.
