Temporal is a durable execution platform that enables developers to build scalable applications by automatically handling failures and retries for units of application logic called Workflows. The platform solves the problem of building reliable distributed systems by providing a server that executes Workflows in a resilient manner, automatically managing intermittent failures and retrying failed operations without requiring developers to implement complex fault-tolerance logic themselves. The approach abstracts away the infrastructure challenges of distributed systems, allowing developers to write application logic as if it were running on a single machine while the platform handles durability, retries, and recovery across failures.
Temporal originated as a fork of Uber's Cadence and is now developed by Temporal Technologies, the startup founded by Cadence's creators. The tool suits teams building microservices, orchestration systems, and workflow automation that need to handle long-running operations reliably. It is particularly valuable for applications requiring distributed cron jobs, service orchestration, or complex multi-step processes where failures are inevitable and must be handled gracefully. The platform provides a Web UI for viewing workflow execution, a CLI for interaction, and SDKs for multiple languages including Go and Java, with sample implementations available for reference.
The project maintains active development with regular contributions to the core server implementation. The codebase includes comprehensive documentation on server architecture and testing practices, with a structured contribution process that includes a proposals system for new features. The project sustains an engaged community through forums and chat channels where developers can discuss implementation details and architectural decisions.
