Constal. The fully equipped agent cloud.

Constal gives you the infrastructure and primitives to define agents and run them at any scale. Write one in a few lines, then scale it safely to billions.

Run any agent on Constal.

SWARMSRun agent swarms on frontier problems.
FACTORIESBuild autonomous software factories.
ASSISTANTSScale to billions of personal assistants.

From one agent to a swarm, in one file.

Every agent is a single definition. Constal handles the sandbox, state, scaling, and governance.

Frontier infrastructure for frontier problems.

ISOLATION
The agent lives outside the sandbox.
Agents run on Constal; the code they write runs in the sandbox. Credentials, state, and control never touch untrusted execution.
DURABILITY
Durable, observable, debuggable.
Every step is checkpointed and every call is traced. Replay any run, step by step, and see exactly what happened.
CONTROL
Steer, interrupt, compose.
Redirect a running agent, pause it mid-step, or wire agents together. Emergent behavior, kept in hand.
GOVERNANCE
Humans in the loop. Policy on everything.
Gate any action behind a person. The platform enforces policy on every call, every time.
PAYMENTS
Agents that pay agents.
Give an agent a budget and it can pay other agents and services per call, inside hard spend limits, with every transaction on the ledger.
MODELS
Any model, any gateway.
Bring your provider, your router, and your keys. Switch without rewriting a line.

Your agents, running today.
