BlueKing CMDB vs Ralph

BlueKing CMDB is an enterprise configuration-management platform for managing assets and applications. Teams can extend built-in model attributes and create models and relationships for networks, middleware and virtual resources. The platform provides machine-data snapshots, automatic discovery and change-event pushes. Host management covers basic attributes, snapshots and ownership relationships; organizational tools manage business-based structures, while process management organizes host processes by module. Event registration and delivery use callbacks. User-group permissions provide access controls, and operation auditing supports tracing user activity. BlueKing CMDB uses a microservice architecture with a Go backend and Vue.js frontend. Deployment documentation lists ZooKeeper, Redis and MongoDB dependencies, with Elasticsearch and Monstache for full-text search. The project supports independent deployment, and its container instructions cover Windows, macOS and Linux Docker environments. The open-source version is MIT-licensed and free, but disables user-management functionality because it runs without login. Documentation, a wiki, a forum, video tutorials and QQ technical groups are listed as support resources.

Ralph is free, open-source software for asset management, data center infrastructure management, and configuration management databases in data centers and back offices. It records hardware purchases, ownership, and asset lifecycles through flexible workflow flows, and includes data center visualization, service mapping, and discovery imports. Ralph can be self-hosted on premises and exposes a REST-style web API for querying and populating its database. API resources support GET, POST, PUT, PATCH, and DELETE, using an automatically generated personal token in the Authorization header. Cloud synchronization supports OpenStack Ocata, with documentation for providers such as AWS. LDAP or Active Directory authentication can be enabled. Ralph is distributed under the Apache 2.0 license and costs nothing. Production Debian packages target Ubuntu 18.04 Bionic on AMD64; Docker Compose installation is experimental. The maintainers provide source without guarantees for issue responses or pull-request support and direct commercial-support seekers to the community forum.
