Virtualmin

Virtualmin is an open-source web hosting control panel for Linux and BSD, built on top of Webmin, that lets administrators and resellers manage websites, virtual servers, DNS, email, FTP, databases, SSL certificates, WordPress and more from a single interface. Distributed as a community GPL edition and a commercial Pro edition, Virtualmin (with its sibling Cloudmin for VM/cloud management) has run for 20+ years and manages over a million domains across 200K+ active users. For automation it exposes a command-line API and an HTTP-based Remote API served from Webmin's remote.cgi on port 10000, covering ~200 documented programs for creating and modifying virtual servers, users, aliases, databases, resellers, plans, templates, SSL certs, backups and cloud storage, with plain-text, JSON, XML or Perl output.

Virtualmin publishes 1 API on the APIs.io network. Tagged areas include Company, Web Hosting, Control Panel, Server Management, and Webmin.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/virtualmin: open an issue to ask a question, or submit a pull request to add artifacts.

  description: HTTP-based Remote API served from Webmin's remote.cgi on port 10000. Each call passes a `program` parameter
    naming one of ~200 command-line programs (create-domain, list-domains, create-user, create-alias, create-database, generate-letsencrypt-cert,
    backup-domain, etc.) plus that program's parameters as CGI query/POST params. Authentication is HTTP Basic as the Webmin
    master administrator. Output is plain text with an exit-status line, or JSON (json=1), XML (xml=1) or Perl (perl=1); list-*
    programs accept multiline for detailed output. The API is self-hosted per Virtualmin installation.

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate — a tool list derived
    from the published API contracts, not an existing server. The scorer already read the manifest and reported mcp_server
    correctly; the MCPServer type was crediting the artifact-type surfaces with a server that does not exist.'
