Restate

Restate deserves a place in the database because it takes a distinct approach to workflow and durable execution infrastructure. The official site positions it as the simplest way to build resilient applications, with workflows-as-code, durable execution, and stateful services that run in existing infrastructure. The key difference is that Restate is not trying to become a generic business automation surface. It is infrastructure for developers who want resilience, retries, sleeps, state, and workflow semantics without adopting a separate orchestration language or moving all code into a proprietary runtime model.

Its packaging is clearer than many emerging workflow platforms. The self-hosted server is distributed as open-source, self-hostable software, while Restate Cloud is fully managed and currently publishes public pricing. The cloud page currently shows Free, Starter at $75/month, Business at $300/month, Premium at $1,000/month, and Enterprise as custom. It also publishes included actions, storage, retention, and overage rates. That makes Restate one of the stronger entries in this category from a pricing-quality perspective.
