Apache CloudStack vs Redocly

Apache CloudStack vs Redocly: at a glance
What is Apache CloudStack?
Apache CloudStack 4.23 ships as a Regular release while two LTS branches stay on maintenance cadence.
Apache CloudStack maintains three active release lines: 4.23.0.0 just shipped as the latest Regular release, 4.22 continues on LTS maintenance with patch 4.22.1.1, and 4.20 received a maintenance tag (4.20.3.1). A security release (4.22.0.1) in May addressed two CVEs — backup access control and instance access violations. The project's multi-branch support model indicates a large installed base that upgrades slowly.
What is Redocly?
Redocly forks Markdoc and points Open in Claude at the desktop app.
Redocly's November 4 package release moved its docs stack to @redocly/markdoc, its own fork of Markdoc, with existing custom tags still working. The same release renders GitHub alert syntax as admonitions, sends Open in Claude to a Claude Code session in the desktop app, adds enum menus to the Try it console, and fixes mock servers that leaked earlier responses. The day before, config 0.71.0 made the docs agent opt-out.

Apache CloudStack
5.0INFRA · APIS
Apache CloudStack 4.23 ships as a Regular release while two LTS branches stay on maintenance cadence.
◆ Current state
Apache CloudStack maintains three active release lines: 4.23.0.0 just shipped as the latest Regular release, 4.22 continues on LTS maintenance with patch 4.22.1.1, and 4.20 received a maintenance tag (4.20.3.1). A security release (4.22.0.1) in May addressed two CVEs — backup access control and instance access violations. The project's multi-branch support model indicates a large installed base that upgrades slowly.
◆ Where it's heading
CloudStack follows a predictable Regular → LTS → maintenance cadence. 4.23 as a Regular release means 4.24 or the LTS designation of 4.23 will come next. The concurrent maintenance of 4.20 alongside 4.22 suggests the project serves operators who can't upgrade quickly — a characteristic of infrastructure software running in production cloud deployments. No signal of architectural pivots.
◆ Prediction
A 4.23.x security or maintenance release will follow within 2-3 months, consistent with historical cadence; 4.23 LTS designation or a 4.24 preview could come mid-2027. Security response is active — operators on 4.22 and earlier should apply the CVE patches.
Redocly
6.3INFRA · APIS
Redocly forks Markdoc and points Open in Claude at the desktop app.
◆ Current state
Redocly's November 4 package release moved its docs stack to @redocly/markdoc, its own fork of Markdoc, with existing custom tags still working. The same release renders GitHub alert syntax as admonitions, sends Open in Claude to a Claude Code session in the desktop app, adds enum menus to the Try it console, and fixes mock servers that leaked earlier responses. The day before, config 0.71.0 made the docs agent opt-out.
◆ Where it's heading
Redocly is taking more of its stack in-house and renaming it around one platform: Reunite options become platform, mcp.docs folds into mcp, and Markdoc is now a fork. The AI hooks point at the desktop agents rather than web chats, which fits the opt-out docs agent shipped a day earlier.
◆ Prediction
Expect the deprecated reunite and mcp.docs names to become errors in a later config release, and more Markdoc tags only Redocly's fork supports.
