Cobbler vs Jackett
A side-by-side editorial comparison of Cobbler and Jackett — release velocity, themes, recent moves, and the top alternatives to consider.
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 It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was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 in pure tracker-maintenance mode, daily domain and category updates only
Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.

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 It was withdrawn 76 minutes after it appeared because its CI packaging workflow never ran on the tag, and 3.3.9 re-shipped the same content once the PyPI publish action was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 in pure tracker-maintenance mode, daily domain and category updates only
◆ Current state
Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.
◆ Where it's heading
The last 10 entries show no feature development — every commit is tracker registration data. Jackett's trajectory is entirely reactive to the torrent ecosystem: trackers move domains, change engines, and die; Jackett follows. There is no observable product initiative in this window.
◆ Prediction
The entries don't support a confident prediction about new feature direction. Daily tracker maintenance will continue as the primary output; any substantive change would come from outside this pattern.
