DeepSeek says its open-source agent app Harness passed 1.54 million daily users and plans a plugin marketplace
Daily users grew more than fourfold from about 271,000 at the end of September, less than three months after launch.
DeepSeek says its open-source AI agent application, DeepSeek Harness, had 1.54 million daily active users as of November 4. The app launched less than three months ago. The company shared the figures on X on Sunday and compared them with about 271,000 users at the end of September. DIGITIMES describes that as more than a fourfold increase. Seeking Alpha reports that DeepSeek also plans a plugin marketplace, and DIGITIMES says the app's plugin ecosystem is growing. The usage numbers come from DeepSeek and have not been independently verified. They matter because open-source agent tools compete with closed products from US labs for developers and businesses, and a plugin marketplace would let outside developers add features to Harness. The supplied reports do not say when the marketplace will open or what terms will apply to plugin developers. Harness is a separate product from DeepSeek's Super-agent coding prototype.
