# Constal

> The managed runtime for long-horizon agents

Durable, observable, governed execution for agents that need to run for months. Use Constal SDK or bring your own framework.

Constal keeps long-running Agent state durable, records execution history, applies Policy at external-call boundaries, and coordinates work across frameworks.

Need the Agent too? We offer a one-year build-and-launch partnership to qualified customers.

## Platform modules

- **SCHEDULER** — Timers, crons, webhooks, and human gates wake agents when work arrives. _CORE_
- **SANDBOX POOL** — Snapshot-warmed microVMs for tool and code execution. Hard isolation per run. _CORE_
- **MODEL GATEWAY** — One interface to every provider, with fallbacks, caching, and cost metering. _OPENAI-COMPAT_
- **MEMORY STORE** — Session, entity, and long-term memory with retention policies attached. _S3-COMPAT_
