DeepSeek has introduced DeepSeek Harness, an open-source agent framework now in worldwide public preview. The company describes it as available as a desktop app or a web interface launched from code, with plugins for tasks including document work, coding and scheduled jobs.

DeepSeek says its open-source agent framework, DeepSeek Harness, is now in worldwide public preview, offering a desktop app for macOS and Windows alongside a web interface developers can launch from code. The release matters to people exploring configurable AI agents because it packages task tools and interface extensions as plugins, while remaining at preview status rather than a documented stable release.

DeepSeek presents Harness as a system for everyday work, coding, research and background tasks. Its examples include organizing files, analyzing data, drafting documents and creating slides, as well as exploring code repositories, fixing bugs, building features and running tests. For research, the company says the agent can find information, verify facts and cite sources. These are capabilities described by DeepSeek; the announcement does not provide independent test results or performance measurements.

The product page says users can install plugins or create them through chat in a feature called Creator mode. Plugins can extend tools, skills and the interface. DeepSeek also points to a Scheduled tasks plugin for starting work at a chosen time or running recurring jobs, and says users can inspect progress and tool-call details. Developer-facing features include execution traces and runtime information for troubleshooting agent activity.

For access, DeepSeek’s page gives developers a web launch command using Node.js: npx @deepseek-ai/dsh web. It also links to a GitHub repository and gives a source-install route using git clone https://github.com/deepseek-ai/deepseek-harness. The page says the system can run as a desktop app or launch its web UI from code, but does not provide detailed installation steps or a feature-by-feature comparison between the desktop and web versions in the supplied announcement.

Plugins Put Users in Control

Harness’s stated design makes extensibility its central proposition: users can add tools or build plugins for their own workflows rather than relying only on a fixed set of built-in functions. A desktop option may also make an agent accessible outside a browser, while the web interface and source repository offer routes for developers to try or adapt the software.

Those options could appeal to users who want one assistant to handle several kinds of work, from documents to coding. But the announcement does not establish how reliably Harness performs these tasks, what models or services are required for each feature, or how it handles sensitive local files. The public preview signals availability for testing, not independently verified readiness for production or high-stakes use.

Desktop and Web Access

DeepSeek describes Harness as built on Cordis’s “everything is a plugin” architecture. The product page frames it as both an application and a framework: users can work through the desktop app, while developers can launch a web UI or install the source. That combination distinguishes the announcement from a release limited to a hosted chat service, although the page does not spell out the full technical architecture.

The company labels the release a public preview and says it is open source. The supplied material does not give a release date, supported operating-system versions, license terms, or a detailed account of what the preview includes on each platform. Readers evaluating the project should consult the linked repository and current installation documentation for those specifics rather than infer them from the general product description.

“DeepSeek Harness is now in public preview worldwide and open source, with composable plugins that extend what agents can do.”

Preview Details Still Missing

The announcement does not specify the desktop app’s minimum macOS or Windows versions, system requirements, or whether the same functions are available across desktop and web. It also gives no detailed information about pricing, account requirements, model access, data retention, privacy protections, or whether tasks run locally or through remote services.

DeepSeek’s descriptions of coding, research and office-work features are product claims, not reported benchmarks. The announcement does not include independent evaluations, known limitations, or a timetable for leaving preview. Users should check the repository and documentation for current technical and licensing details before installing or using the software with sensitive material.

Check the Repository for Updates

Interested users can follow DeepSeek’s GitHub repository and product documentation for installation guidance, platform requirements and changes to the preview. Developers can try the published web launch command after installing Node.js, while desktop users should confirm that current downloads support their operating system.

DeepSeek has not announced a date for a stable release or outlined a roadmap in the supplied material. The next concrete details to watch for are documentation on desktop setup, the scope of the open-source license, and further information on how plugins and scheduled tasks operate.
