Cobbler vs Redocly: at a glance
What is Cobbler?
Cobbler's 3.3 backport branch ships Leap 16 and Agama support, then has to re-cut the release
Cobbler's public releases are all 3.3-branch backports, and the branch just had its most substantial drop in nearly two years. 3.3.8 added import and manage support for openSUSE Leap 16 and its Agama installer, interactive and automatic XCP-ng network installs, and basic Python 3.13 support. It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was fixed. Before that pair, recent history is dominated by the CVE-2024-47533 admin-API bypass, patched on both 3.3 and 3.2.
What is Redocly?
Redocly ships a built-in MCP server page across its entire docs platform, with public and authenticated endpoints
Redocly just landed a coordinated 0.137.0 release across Reef, Realm, Revel, and Redoc, anchored by a structural addition: every developer portal now ships a `/mcp` page with setup instructions for Claude, ChatGPT/Codex, and raw JSON config, plus an opt-in `/mcp-public` endpoint for serving anonymous-accessible content without authentication. The MCP code mode got reliability improvements, OAuth discovery was fixed to spec (RFC 8414), and four CVEs were patched in the same release. The breadth of the drop — 20 features and 67+ bug fixes across packages — reflects a team that released a major capability and simultaneously cleared accumulated UX debt.

Cobbler

Cobbler's 3.3 backport branch ships Leap 16 and Agama support, then has to re-cut the release
◆ Current state
Cobbler's public releases are all 3.3-branch backports, and the branch just had its most substantial drop in nearly two years. 3.3.8 added import and manage support for openSUSE Leap 16 and its Agama installer, interactive and automatic XCP-ng network installs, and basic Python 3.13 support. It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was fixed. Before that pair, recent history is dominated by the CVE-2024-47533 admin-API bypass, patched on both 3.3 and 3.2.
◆ Where it's heading
The branch is tracking new installer and distro ecosystems rather than winding down: Agama and XCP-ng are current targets, and Python 3.13 support keeps the package installable on newer hosts. Release engineering is the weak point, and the entries show why - SHA-pinning GitHub Actions inside CI is what broke the publish step, at the cost of a same-day defunct-and-replace. Feature work continues to arrive as rollups from main rather than as branch-native development.
◆ Prediction
Expect the next 3.3.x tag to be another backport rollup, with CI hardening following the 3.3.9 failure. Whether the main line cuts a 3.4 is not something these entries show.

Redocly ships a built-in MCP server page across its entire docs platform, with public and authenticated endpoints
◆ Current state
Redocly just landed a coordinated 0.137.0 release across Reef, Realm, Revel, and Redoc, anchored by a structural addition: every developer portal now ships a `/mcp` page with setup instructions for Claude, ChatGPT/Codex, and raw JSON config, plus an opt-in `/mcp-public` endpoint for serving anonymous-accessible content without authentication. The MCP code mode got reliability improvements, OAuth discovery was fixed to spec (RFC 8414), and four CVEs were patched in the same release. The breadth of the drop — 20 features and 67+ bug fixes across packages — reflects a team that released a major capability and simultaneously cleared accumulated UX debt.
◆ Where it's heading
Redocly is repositioning every hosted API portal as a first-class AI agent resource, not just a human-readable docs site. The public MCP endpoint especially matters: it enables AI coding assistants to read API docs without credentials, which removes the main friction for developers integrating via LLM tools. Security hardening (audience validation, OAuth compliance, CVE patching) in the same release signals this isn't a prototype feature — it's going into production. The next logical step is deeper programmatic authoring via the MCP surface, not just reading.
◆ Prediction
Expect Redocly to add MCP write-path features — letting AI agents update API documentation or sync specs directly — once the read-path is fully stable. The visual review check in Reunite suggests a git-workflow integration direction.
