DeepSeek to Launch Official Plugin Marketplace and Developer Grants for Harness AI App

DeepSeek plans to launch an official plugin marketplace and a creator program offering technical support and token grants to plugin authors for its Harness agent platform. The initiative aims to expand its open-source ecosystem and compete with agentic software from OpenAI and Anthropic. The Harness app reached 1.54 million daily active users on Nov. 4, up from a seven-day average of 271,000 on Sept. 30, with roughly 60% of users having installed or created one of the app's 35,000 plugins.
