Every step you take, every call you make: the reliable agent stack — Giselle van Dongen, Restate

Running AI agents reliably in production requires moving beyond simple SDKs toward robust infrastructure that supports durable execution and state management. As agentic systems evolve into persistent, asynchronous entities, they demand capabilities like automatic failure recovery, concurrent session handling, and inter-agent communication. Restate provides this foundation by acting as a server-side proxy that logs events to ensure processes can resume exactly where they left off after crashes or network failures. By utilizing virtual objects and durable promises, developers can build stateful agents capable of handling long-running workflows, such as human-in-the-loop approvals, without complex manual retry logic. This event-driven architecture enables high-performance, low-latency execution, allowing organizations to scale complex agentic platforms while maintaining consistent state and control over long-term, distributed processes.
