Quay vs Jackett: at a glance
What is Quay?
The public release feed is pure CVE backporting across two frozen branches.
Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.
What is Jackett?
A daily patch cycle keeping several hundred tracker definitions from going stale.
Jackett ships a build essentially every morning, and each one is the same kind of work: tracker definitions re-pointed at moved domains, CSS selectors repaired after a site redesign, category mappings corrected, and dead indexers deleted. The last ten releases removed six trackers outright (chilebt, FilmesHdTorrent, torr9, rain, runtheframes, elitetorrent-wf) while adding native torznab API support for pornotorrent and private-tracker handling for simurg. The changelogs are auto-generated commit lists, so the release notes are the commit subjects.

Quay
5.0INFRA · APIS
The public release feed is pure CVE backporting across two frozen branches.
◆ Current state
Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.
◆ Where it's heading
This is what a supported enterprise registry looks like from the outside: two older branches on life support for customers who have not moved, with feature development happening somewhere the feed does not see. The pattern is machine-driven — cherry-pick robots, changelog bump bots, Renovate-style dependency updates — with human authorship visible mainly on the security fixes. Nothing here indicates what the current development branch is doing.
◆ Prediction
Expect the 3.10 and 3.12 branches to keep receiving paired dependency CVE backports on the same cadence until their support windows close. Any read on Quay's product direction needs a source other than this feed.
Jackett
5.0INFRA · APIS
A daily patch cycle keeping several hundred tracker definitions from going stale.
◆ Current state
Jackett ships a build essentially every morning, and each one is the same kind of work: tracker definitions re-pointed at moved domains, CSS selectors repaired after a site redesign, category mappings corrected, and dead indexers deleted. The last ten releases removed six trackers outright (chilebt, FilmesHdTorrent, torr9, rain, runtheframes, elitetorrent-wf) while adding native torznab API support for pornotorrent and private-tracker handling for simurg. The changelogs are auto-generated commit lists, so the release notes are the commit subjects.
◆ Where it's heading
This is maintenance as the product, and the churn rate is the signal worth watching. Indexer definitions decay continuously because the sites behind them move domains, change markup, and disappear, so Jackett's value is the speed of the repair loop rather than any feature roadmap. The removals slightly outpace the additions across this window, which is the normal shape for a catalog tracking sites that go dark. Where real capability does appear it is narrow and per-indexer — a native API adopted here, freeleech parsing corrected there.
◆ Prediction
Expect the daily cadence and the same mix to continue: domain bumps and selector repairs as the bulk, a handful of indexer removals, and occasional per-site API or category work. Nothing in these entries points to a structural change in how definitions are maintained.
