Cobbler vs Jackett: 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 It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was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 Jackett?
Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.

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 It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was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.
Jackett
5.0INFRA · APIS
Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.
◆ Current state
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.
◆ Where it's heading
The work is entirely maintenance. Its value depends on keeping up with a tracker ecosystem where sites change domains and layouts weekly. Where possible, the project is moving definitions to sturdier integrations, such as switching world-of-tomorrow to its Torznab API and retiring trackers that moved to direct downloads.
◆ Prediction
Expect the daily cadence to continue, with more trackers moved to API-based definitions and more dead sites removed. Core changes stay rare.
