Xata – Open-source Postgres platform with CoW branching

Xata is a pure open-source, cloud-native, platform for self-hosting a large number of Postgres instances on top of Kubernetes, offering the following functionality (and more) built in:

• Fast branching using Copy-on-Write at the storage level. You can “copy” TB of data in a matter of seconds
• Scale-to-zero functionality (remove compute instance on inactivity, add it back automatically on connections)
• Auto-scaling of the compute nodes, bin-packing them for cost efficiency
• High-availability / Read-replicas with automatic failover
• Upgrades, configuration edits, scale up/down with minimal downtime via switchover
• Separation of storage and compute as well as local storage if preferred
• PITR backups to object storage
• Serverless driver (SQL over HTTP/websockets)
• REST APIs and CLI for managing all “control-plane”
