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?
A backport branch kept alive for downstreams, with the main line nowhere in sight.
Every release in Cobbler's visible history describes itself the same way: backports from main to make Cobbler more stable for the community. The 3.3.x line has absorbed real work under that framing — collection indices, lazy loading, new XML-RPC endpoints — but none of it originates here. The most recent item is a 3.2.3 build carrying the CVE-2024-47533 fix to an older branch, with its Fixed and Added sections left as literal TBD placeholders.
What is Jackett?
A daily indexer-repair treadmill: Jackett patches tracker definitions as fast as trackers change.
Jackett cuts a release nearly every morning, and each one is a batch of tracker-definition edits rather than application changes. Across the last ten releases there is no work on Jackett itself — no UI, no API, no core engine changes — only YAML definitions: domain bumps, category mappings, selector repairs, auth-format switches, and removals of trackers that went dark. The one direction of growth is the catalog: simurg was added as a new private tracker, while desigaane and simurg both moved to API-key authentication for downloads.

A backport branch kept alive for downstreams, with the main line nowhere in sight.
◆ Current state
Every release in Cobbler's visible history describes itself the same way: backports from main to make Cobbler more stable for the community. The 3.3.x line has absorbed real work under that framing — collection indices, lazy loading, new XML-RPC endpoints — but none of it originates here. The most recent item is a 3.2.3 build carrying the CVE-2024-47533 fix to an older branch, with its Fixed and Added sections left as literal TBD placeholders.
◆ Where it's heading
This is a stabilization branch serving downstream packagers rather than a product advancing on its own. The work that does land splits cleanly into three buckets: distribution coverage (Ubuntu 22.04, Debian 12, AlmaLinux, RHEL9, openSUSE and SLE signatures), API surface for integrators, and security backports. 3.3.3 flagged dump_vars as the replacement for get_blended_data as of 3.4.0 — a version that has not appeared in any release since.
◆ Prediction
Expect continued single-purpose backports to 3.3.x and older branches as CVEs surface; the entries give no indication of when or whether the 3.4.0 work these releases keep deferring to will ship.
Jackett
5.0INFRA · APIS
A daily indexer-repair treadmill: Jackett patches tracker definitions as fast as trackers change.
◆ Current state
Jackett cuts a release nearly every morning, and each one is a batch of tracker-definition edits rather than application changes. Across the last ten releases there is no work on Jackett itself — no UI, no API, no core engine changes — only YAML definitions: domain bumps, category mappings, selector repairs, auth-format switches, and removals of trackers that went dark. The one direction of growth is the catalog: simurg was added as a new private tracker, while desigaane and simurg both moved to API-key authentication for downloads.
◆ Where it's heading
This is maintenance mode by design, not by neglect. The work is reactive on a one-day lag: a tracker moves hosts or changes markup, and the definition follows in the next morning's release. Volume holds steady at roughly three to eight commits per release with no accumulation toward a larger change, and the removals (FilmesHdTorrent, torr9, rain) roughly offset the additions.
◆ Prediction
Expect the same daily cadence of definition patches — more domain bumps, more category mappings, and further migrations to API-key auth as trackers close off unauthenticated scraping. Nothing in these entries points to core application work being queued.
