DeepSeek Harness 0.2 Adds Windows and macOS Desktop Apps
Version 0.1 arrived in August 2026 and became the agent most used by DeepSeek API users, so the desktop build and plugin layer move the product from an API-side tool toward something users run directly on their own machines.

DeepSeek released version 0.2 of its coding agent DeepSeek Harness on October 1, 2026, adding desktop apps for Windows and macOS. The desktop build can display slide materials, web pages, and code diffs, and supports plugins such as one for periodic task execution and one for voice input. DeepSeek says more updates are planned, including stronger sandboxing, a memory function, and smartphone access.
DeepSeek opened the desktop version of its coding agent on October 1, 2026, with the 0.2 release adding Windows and macOS apps alongside the existing agent. Inside the desktop app, users can view slide materials and web pages created with AI, and code diffs are displayed there too.
The plugin system carries the rest of the release. Plugins cover periodic task execution and voice input, and the whale mascot in the corner of the interface comes from one as well. Users can write plugins themselves, and DeepSeek says AI can handle everything from creating a plugin to installing it.
