About Restate
Restate is a runtime for building durable backends, workflows and AI agents. It keeps state and retries work so that a failed step does not lose progress.
What it does
Restate runs your code as durable functions. Each step is recorded in a distributed log, so a function can pick up where it stopped after a crash. The runtime also includes keyed state, timers, queues and service-to-service calls, which can reduce the number of separate tools a backend needs.
Key features
- Durable functions that resume after failures
- Keyed state and virtual objects
- Queues, timers and RPC calls in one runtime
- Ships as a single binary you can self-host
- Managed cloud and bring-your-own-cloud options
Who it's for
Restate suits backend teams building workflows, financial processes and AI agents that need to keep working through errors. Platform teams that want fewer moving parts may also find it useful.
Pricing and good to know
The runtime is available as open source and can be self-hosted as one binary. Restate Cloud is a managed option that the site describes as free to start. A bring-your-own-cloud option runs the managed service inside your own cloud account. The site lists low latency figures for durable steps, which depend on your setup.
