Le verdict

Choisissez Tulsk si
you need a hosted system for projects, tasks, team collaboration, agent governance, and cross-functional work beyond software development.
Choisissez DeepSeek Harness si
you want to inspect, extend, and self-host a developer-preview coding harness whose models, tools, loop, persistence, and interface are plugins.
La principale différence porte sur
Tulsk manages shared company work; DeepSeek Harness gives developers direct control of an extensible agent runtime inside a code workspace.

Où elles divergent vraiment

Les différences qui comptent une fois l'outil en usage.

Team workspace vs developer harness

Tulsk

Tulsk is where a company defines, assigns, discusses, and reviews work. People and agents share projects, tasks, comments, files, schedules, and activity history.

The managed runtime stays behind the product surface, so teammates can use agents without installing or operating agent infrastructure.

DeepSeek Harness

DeepSeek Harness is the runtime and developer interface. A user selects a local code workspace, starts a session, and lets the agent inspect files, edit code, run commands, delegate work, and maintain a plan.

It does not provide a collaborative project-management layer comparable to Tulsk.

Managed configuration vs plugins

Tulsk

Tulsk exposes product-level controls: agent roles, model selection, skills, tool grants, approvals, integrations, schedules, channels, and run history.

DeepSeek Harness

DeepSeek Harness is built on Cordis and treats every major subsystem as a plugin. Developers can replace model adapters, tools, persistence, the agent loop, policies, interfaces, and other capabilities through profiles and configuration layers.

That flexibility is powerful, but it makes the operator responsible for composing and maintaining the runtime.

Hosted budget vs self-hosted cost

Tulsk

Tulsk includes managed compute and an agent-work allowance in each plan. The team sees usage and outputs in the same hosted workspace.

DeepSeek Harness

DeepSeek Harness is free, MIT-licensed software. The operator supplies model credentials and the machine, storage, networking, and optional sandbox services, so total cost follows provider usage and deployment choices.
