Downcity Docs

Agent infrastructure docs for AI builders using Downcity.

Downcity is agent infrastructure for AI builders. These docs help you run local agents, connect City, connect models and powers, and turn agent workflows into real product surfaces.

The shortest product model:

  • products own the user experience
  • agents execute work inside explicit runtime boundaries
  • Downcity provides the reusable runtime layer for models, tools, tasks, memory, services, permissions, usage, billing, and control surfaces
