See what Ralph, Allegro's open-source Asset Management and DCIM system, offers: features, REST API, pricing (free), and FAQs.
Ralph is an open-source Asset Management, DCIM, and CMDB system originally built and published by Allegro, the Poznan, Poland-based e-commerce company behind the Allegro.pl marketplace. It is designed to track the full lifecycle of data center and back-office hardware, from purchase through deployment and eventual retirement.
Released under the Apache License 2.0 and built on Python and Django, Ralph exposes nearly all of its functionality through a REST API, making it well suited to organizations that want to integrate asset data with other internal systems rather than relying solely on its web interface.
Ralph's DCIM module includes interactive floor plans that visualize rack layouts, power distribution, and physical asset placement, while its IPAM capabilities cover IP address management with DHCP and DNS integration and network topology visualization. It also tracks software licenses and vendor support contracts.
The system supports organizing assets across multiple regions, data centers, and service environments, and its comprehensive REST API, built on Django REST Framework, allows every feature to be accessed and automated programmatically rather than only through the web UI.
Ralph is completely free to download, self-host, and modify under the Apache 2.0 license, with no paid tiers or license fees from Allegro. Organizations only bear the cost of the infrastructure they run it on and the engineering time required to deploy and maintain it.
Allegro maintains Ralph under a 'sources only' model, continuing to publish source code and planning modernization investment, but without formal support guarantees; community and commercial support inquiries are directed to the project's discourse forum rather than a dedicated vendor help desk.

Both are free, open-source data center asset tools, but Ralph is Python/Django-based with a stronger REST API and CMDB features, while RackTables is PHP/MySQL-based and focuses more narrowly on rack and IPAM visualization.
Allegro has stated it continues to publish source code and plans to invest in modernizing Ralph, though development follows a 'sources only' model rather than a committed public roadmap.
