Restack is a backend framework designed to provide long-running workflows and infrastructure for reliable and accurate AI agents. It enables developers to build scalable AI agents capable of orchestrating millions of conversations in parallel. Restack’s long-running agents come with built-in memory, allowing chatbots to persist context and state for extended periods without requiring additional infrastructure management. The framework supports both Python and TypeScript, offering event-driven processes that maintain state and run continuously. Restack also features API endpoints for starting workflows and agents from any client, task queues for managing execution with rate limits and concurrency policies, and retry policies for error handling. Additionally, it includes cron-jobs for scheduled tasks and frontend integration with React Flow for creating visual agent interfaces. Restack can be deployed on Kubernetes clusters, offering flexible options such as Restack Cloud, on-premises, or custom cloud environments. The developer toolkit provides a UI for visualizing and replaying workflows, enhancing debugging and local development. Restack aims to build the framework for reliable and accurate AI agents, ensuring they are scalable, ready for real-world use, and capable of handling long-running tasks efficiently.
