Jackett vs Contour
A side-by-side editorial comparison of Jackett and Contour — release velocity, themes, recent moves, and the top alternatives to consider.
Jackett vs Contour: at a glance
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.
What is Contour?
Three supported branches, patched in lockstep within the same minute.
Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.

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.
Contour
0.0INFRA · APIS
Three supported branches, patched in lockstep within the same minute.
◆ Current state
Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.
◆ Where it's heading
This is a proxy whose release cadence is governed by its data plane rather than its own feature work. Envoy security releases set the schedule, and Contour's job is to bump, verify compatibility and ship across every supported branch simultaneously. The changes that do originate in Contour are operational sharp edges found in production: an HTTPProxy CRD schema wrongly marking a status error field as required, which broke load balancer status updates, and shutdown-manager being CPU-throttled at a 50m limit.
◆ Prediction
The next release will almost certainly be another simultaneous three-branch batch triggered by an Envoy security bump, since both batches in this window followed exactly that pattern.
