OpenEverest vs PostgreSQL Maestro

OpenEverest is a free, open-source platform for provisioning and managing databases, storage, and LLMs on Kubernetes. Teams can create database instances through the UI, API, or CLI, choosing topologies, versions, and presets. The listed workloads include MySQL, MariaDB, MongoDB, PostgreSQL, ClickHouse, Microsoft SQL Server, TiDB, and Valkey; its FAQ also names Apache Cassandra and KServe. Users can scale by adding nodes, shards, or replicas and adjusting CPU, memory, and storage. The platform supports scheduled backups to S3-compatible storage, point-in-time recovery, and cloning an instance from a backup. It can send metrics to an existing observability stack without requiring a particular monitoring tool. Built-in protections include TLS, generated credentials, and role-based access control. A guided interface covers storage classes, pod scheduling, external access, and database engine parameters. OpenEverest can run on Kubernetes in public or private clouds, on bare metal, or on-premises. Its components are available under Apache 2.0. Version 1 is current; version 2 is a developer preview that is not feature-complete or intended for production.
