Cobbler vs Skipper: 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 It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was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 Skipper?
Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement
Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

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 It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was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.

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement
◆ Current state
Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.
◆ Where it's heading
Skipper is building out its security posture at the proxy layer: RFC 9421 request signing, Redis L2 cache (v0.27.92), and security header handling improvements (v0.27.88) suggest a consistent push toward production-grade security primitives without architectural breaks. The performance improvements in v0.27.95 address real-world Kubernetes clusters where large RouteGroup counts are common.
◆ Prediction
RFC 9421 support will likely get expanded configuration options — signing key rotation, policy enforcement modes, per-route key selection — as Zalando's internal adopters surface operational requirements for the filter.
