Roundup: 12 popular third-party plugins for DeepSeek Harness

On October 21, 2026, Zhidongxi published a roundup of third-party plugins built for DeepSeek Harness. According to the report, the project had surpassed 250,000 stars on GitHub by that day, roughly two months after it was open-sourced. Over that period, a growing number of developers had begun building plugins for it, with related open-source projects continuing to appear.

The outlet said it gathered third-party plugins and adaptation projects for DeepSeek Harness from GitHub, X, Reddit and other platforms, then selected 12 projects worth watching. The selection weighed each project's GitHub star count alongside the attention it received on communities such as X and Reddit and recommendations from well-known developers. Some of the listed projects had already reached tens of thousands of stars on GitHub, and some had more than 100,000, the report said. It also noted that some had drawn attention and recommendations from Cui Tianyi, who leads DeepSeek's product division and the DeepSeek Harness team.

Among the specific projects mentioned, the main repository for the open-source design tool OpenDesign had reached 102,800 stars, and the sidebar enhancement plugin DSH Better Side was also included in the roundup. The report described other small tools aimed at specific problems: helping text-only models understand screenshots, allowing long-running tasks to continue after context compression, and editing a resume directly within a conversation. The report did not disclose the full list of the 12 projects or give release dates for individual entries.
