workflowsto

Workflowsto is a modular framework for modeling, automating, and observing multi-step processes that span distributed systems. It offers a declarative language or API for composing tasks into workflows, plus runtime components that execute, monitor, and adapt workflows at scale.

Its architecture centers on a lightweight workflow engine, a pluggable task registry of executors, a persistent state store, an event bus, and adapters for external systems. Workflows are defined in a declarative format (JSON or YAML) and can express sequencing, parallelism, branching, retries, and compensation steps. Backends for storage and messaging are pluggable to fit different environments.

Execution is event-driven and stateful. It supports long-running tasks, timeouts, retry policies, and idempotent semantics. The engine can resume from checkpoints after failures and offers audit trails through event sourcing.

Common use cases include data processing pipelines, business process automation, ETL tasks, CI/CD orchestration, and infrastructure automation. Workflowsto integrates with cloud services, databases, and queues via adapters and connectors.

The project emphasizes language-agnosticism and portability, with client SDKs in several languages and a plugin architecture that encourages community contributions. It is used in organizations seeking to decouple process design from implementation details and to improve observability of complex workflows.
