Restate review

Restate places fifth as the most language-flexible engine after Temporal. It provides SDKs for TypeScript, Python, Java, Kotlin, Go, Rust and Ruby, and services written in different languages share one protocol and can call each other. You write handlers as normal code, and Restate makes each step durable so the code survives failures; Virtual Objects add durable state keyed to an entity. Restate also documents use with agent frameworks such as the OpenAI Agents SDK, Google ADK, Pydantic AI and LangChain, and runs services on serverless platforms like Vercel, AWS Lambda and Cloudflare. The server is open source under a permissive license and free to self-host. Restate Cloud has a Free plan with 100k actions, Starter at $75 a month with 5M actions and Business at $300 a month with 20M. Free is limited to 10 actions per second, and HIPAA and multi-AZ redundancy are paid add-ons.
