Ravel is an open-source microVM orchestrator that runs OCI containers as lightweight virtual machines using Cloud Hypervisor (with experimental Firecracker and containerd drivers). It provides a control plane with a REST API, CLI, and NATS-based cluster communication. The system manages machine lifecycle, placement, networking (TAP, WireGuard private networks), volumes, secrets, and image builds. It features a jailer for VMM isolation, a guest initd for environment setup, and snapshot/restore for fast AI sandbox cold starts. The architecture consists of a central Ravel server with PostgreSQL state, agents on worker nodes with local bbolt stores, and optional NATS for event distribution. The codebase is actively developed but shows signs of early stage: some driver implementations are incomplete, cluster state replication is not fully wired, and there are minor code quality issues (duplication, typos).
