Plan the workflow once you know where CoCalc runs.
Where CoCalc runs decides who operates it. The next decision is how people, agents, and compute should use the project there.
Agents and collaboration
See how people and agents use the same project files, notebooks, terminals, services, and review context.
Compute capacity
Compare moving the whole project to a dedicated machine with connecting a notebook to a machine you already have, before choosing capacity.
Execution model
Decide whether the work needs a persistent, shared project or an API-managed execution environment.
