DeepSeek Harness is an MIT-licensed developer-preview runtime built on Cordis, where the model adapter, tools, session log, agent loop, UI, and policies are composable plugins. Orkas is an MIT-licensed, local-first desktop product where a Commander coordinates built-in and reusable specialist agents across research, documents, operations, media, and code.
Both run locally and can delegate work. The difference is which layer you want to own.
DeepSeek Harness leads in low-level runtime composability; Orkas leads in packaged, cross-work desktop experience.

Not as a one-to-one replacement. DeepSeek Harness is a developer-preview agent runtime whose model adapters, tools, session log, agent loop, and UI are composable plugins. Orkas is a finished local-first desktop workspace where a Commander coordinates reusable specialist agents across research, documents, operations, media, and code. Choose by whether you want to build the harness layer or use the product layer.
DeepSeek Harness runs as an ordered Cordis plugin tree. Profiles stack bundles and patch layers, while an append-only session event log supplies model context and replay. Orkas packages the coordination model: one Commander recruits agents with skills and bounded context inside a desktop conversation.
Yes. Both are MIT-licensed and run locally. DeepSeek Harness supports DeepSeek, catalog providers, and custom compatible endpoints. Orkas offers optional managed official models or your own provider; with your own provider, model calls go directly to it.
Choose DeepSeek Harness when you need to replace the agent loop, tools, session system, policies, or UI; run custom profiles; or embed a headless runner. Choose Orkas when you want a downloadable desktop product with built-in specialists, memory, skills, connectors, and cross-work workflows.
Keep the Commander, specialists, memory, skills, and handoffs together in one desktop conversation.
