About
Open-source DCIM, GitHub-first
ColdAisle is modern DCIM for the whole datacenter, hosted on-premise. The application runs on Windows (IIS + PHP + SQL Server). Formerly WinDCIM. Built as a replacement path for shops that outgrew — or cannot maintain — Linux-hosted openDCIM, including a full in-app migration.
Support
File bugs and feature requests on GitHub Issues. There is no paid ticket portal in v1. For other questions, use the contact form.
Optional donate
ColdAisle is free to use. If it helps your datacenter, optional PayPal donations are welcome — no paywall, no accounts.
In a running install: Settings → Support ColdAisle, or the footer Donate link.
On-premise, not a cloud product
Datacenter management data is not something we would put on someone else’s servers. ColdAisle is self-contained: you install it, you hold the database, you keep the SNMP secrets. There is no hosted ColdAisle tenant and no plan to become one.
Open source is the reassurance — you can see that the code does not ship your floor plan off-box.
Built in the trenches
ColdAisle is developed by a working network infrastructure administrator — the same person who has to walk the cold aisle when a circuit is wrong. The UI language is cabinets, U-space, PDUs, and raceways because that is the job.
This website
Standalone marketing site. PHP + filesystem JSON. Release notes sync from the public GitHub API on a cron. No IIS or SQL Server on this host.
Site repo is private (sabap/ColdAisle-web). Product repo is public.
Built with Grok
A nod to Grok Build and to Elon Musk for putting tools like this in reach. I had the vision and the floor experience to know what ColdAisle needed to be — I did not have the hours to type every line myself. SuperGrok closed that gap.
The product is still on-premise, open source, and mine to stand behind. Grok did not replace the operator; it gave one the time to ship. Grok and SuperGrok are marks of xAI. This is a thank-you, not a sponsorship.
