DeepSeek Harness Reaches 1.54M Daily Users, Plans Official Plugin Marketplace

DeepSeek Harness, DeepSeek's open-source agent runtime, had 1.54 million daily active users as of November 4, according to an update the Harness team posted on the evening of November 5. Pandaily reports the figures, citing IT Home and MyDrivers. The team also said it will build an official plugin marketplace.

The numbers

• Daily active users: 1.54 million as of November 4. The count covers only users who access the product through DeepSeek's official API.
• Token consumption: about 92 trillion tokens a day across those users.
• Third-party plugins: about 35,000 since launch.
• Plugin adoption: around 60% of active users have built or installed at least one plugin.

Growth timeline

DeepSeek Harness v0.1 went live on August 13. The desktop version launched on September 29. MyDrivers noted that daily active users stood at about 271,000 on September 30, which means the user base grew more than fivefold in a little over a month.

Everything is a plugin

The plugin count reflects the product's core design, often summarized as "everything is a plugin." Models, tools, skills, sessions, sandboxes, storage, loops, scheduling and the user interface are all assembled from plugins. Users can swap these out and recombine them.

What the team plans next

The update lists three priorities:

1. Improve the stability and compatibility of the plugin API.
2. Strengthen plugin security mechanisms.
3. Build an official plugin marketplace, so authors can publish plugins more easily and users can find the ones they need.

The team is also preparing a support program for plugin authors. It will offer token incentives, technical exchanges and featured placement, with details to be shaped by community needs and feedback. DeepSeek also invited startups and companies to bring their products, services and specialist capabilities into Harness as plugins and to explore partnerships.

The team did not give a launch date for the marketplace or the author program.

What this means

The figures show Harness usage is concentrated in plugins: with about 60% of active users having built or installed at least one, the plugin system is central to how people use the product rather than an add-on. The planned marketplace would give that ecosystem a central distribution point for the first time, alongside the community indexes and repositories developers have relied on so far.

The stated focus on plugin API stability and security matters because every major component of Harness is a plugin. Compatibility changes in the API affect models, tools and the interface alike. Token incentives for authors would also tie plugin development to consumption through DeepSeek's API. The 1.54 million figure excludes anyone not using the official API, so it does not measure total usage of the open-source runtime.
