Restate is a durable execution platform for building resilient distributed applications, microservice orchestration, durable workflows, stateful services, and AI agents. Founded by Apache Flink and Apache Kafka veterans (Stephan Ewen, Igal Shilman, Till Rohrmann), Restate ships a single-binary Rust runtime that journals every step of handler execution so code survives crashes, restarts, and infrastructure failures. The platform exposes an Ingress API on port 8080 for HTTP invocation of services, virtual objects, and workflows (with idempotency keys, async /send semantics, and delayed invocations) and an Admin API on port 9070 for deployment registration, service introspection, invocation control (cancel, kill, pause, resume, restart, purge), subscriptions, and cluster health. Official SDKs target TypeScript, Java/Kotlin, Python, Go, Rust, and Ruby, with first-class integrations for AWS Lambda, Cloudflare Workers, Deno Deploy, Vercel, and Kubernetes (via the restate-operator). Restate Cloud is the managed offering with SOC 2 Type I compliance, enterprise SSO (Okta, Google Workspace, Azure AD), HIPAA BAAs, and an in-preview client-side journal encryption feature.

## Use cases (8)

- **Microservice Orchestration** — Coordinate multi-service business transactions with automatic retries, compensation, and timeout handling using durable handlers.
- **Durable AI Agents** — Build agents that survive process crashes and replay tool calls deterministically, with integrations for OpenAI, LangChain, Pydantic AI, Vercel AI, Google ADK, and LiteLLM.
- **Step Functions and Workflow Engines** — Replace AWS Step Functions / Azure Durable Functions / hand-rolled state machines with code-first workflows in your language of choice.
- **Background Jobs and Async Tasks** — Run reliable background jobs with retries, idempotency, and scheduling without a separate queue and worker infrastructure.
- **Saga-Based Distributed Transactions** — Implement compensating-action sagas for cross-service operations like order fulfillment, payments, and inventory reservation.
- **Stateful Serverless APIs** — Combine virtual-object state with FaaS deployment on AWS Lambda, Cloudflare Workers, Deno Deploy, or Vercel for stateful serverless apps.
- **Event-Driven Workflows** — Subscribe handlers to Kafka topics so each event triggers a durable, exactly-once workflow invocation.
- **Human-in-the-Loop Approvals** — Pause workflows on awakeables that wait for webhook callbacks, signed URLs, or human approvals for arbitrary durations.
