It enables the development of fault-tolerant, stateful distributed systems by managing execution state, retries, and timeouts. Engineers can write complex business logic that remains durable across infrastructure crashes, ensuring tasks complete successfully without manual intervention or custom state-tracking persistence layers.

Backend engineers, site reliability engineers, and distributed systems architects benefit most. It is designed for teams building mission-critical services that require high availability, complex state management, and robust error handling across distributed microservices environments.

The core system is available under the MIT License, making it open-source software. Users can self-host the infrastructure components at no cost, or opt for managed cloud offerings provided by the organization for enterprise-grade support and operational management.
