Golem

Golem is an open-source durable computing platform for building agents and distributed applications that never lose state. You deploy WebAssembly components and invoke durable serverless workers through a REST API; the runtime transparently persists every worker's execution so it survives crashes, restarts, and redeploys. Golem ships as open source you self-host and as the managed Golem Cloud hosted service.
