OpenKruise vs Jackett: at a glance
What is OpenKruise?
Seven workload APIs graduated to beta — then the feed went quiet for six months.
OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.
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.

OpenKruise
0.0INFRA · APIS
Seven workload APIs graduated to beta — then the feed went quiet for six months.
◆ Current state
OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.
◆ Where it's heading
This is a project consolidating rather than expanding — graduating APIs to beta is a commitment to stop changing their shape, and the accompanying features fill gaps in existing controllers rather than adding new ones. The pod resize protection is the one forward-looking item, tracking in-place resource resizing as it stabilizes upstream in Kubernetes. Whether the v1.9.0 line ever reached a stable release is not visible here.
◆ Prediction
The obvious next step is a stable v1.9.0 with the v1beta1 APIs finalized. The six-month gap since the last alpha is worth verifying against the project's actual release activity before reading it as a slowdown.
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.
