Jackett vs Quay
A side-by-side editorial comparison of Jackett and Quay — release velocity, themes, recent moves, and the top alternatives to consider.
Jackett vs Quay: at a glance
What is Jackett?
Jackett ships daily, and every release is tracker definitions chasing sites that moved
Jackett cuts a release most mornings, each one a batch of indexer definition edits generated straight from the commit log. The work is uniform: new alternate domains for trackers that relocated, category mappings added or corrected, selectors repaired after a site changed its markup, and the occasional indexer removed when it goes dark. Recent releases also switched two trackers to API key authentication and added a public DHT crawler to another.
What is Quay?
Quay ships nothing but CVE remediation, mirrored across two supported branches
Every entry in Quay's recent history is a security maintenance release, and they arrive as coordinated pairs — a 3.10.x and a 3.12.x tag cut hours apart carrying the same fixes cherry-picked to each branch. The content is dependency remediation against tracked advisories plus two SSRF hardening fixes, one in proxy cache upstream registry configuration and one in repository mirroring sources. No feature work appears in the window.

Jackett ships daily, and every release is tracker definitions chasing sites that moved
◆ Current state
Jackett cuts a release most mornings, each one a batch of indexer definition edits generated straight from the commit log. The work is uniform: new alternate domains for trackers that relocated, category mappings added or corrected, selectors repaired after a site changed its markup, and the occasional indexer removed when it goes dark. Recent releases also switched two trackers to API key authentication and added a public DHT crawler to another.
◆ Where it's heading
Nothing about the application itself is changing in this window — the engine is stable and the product is the definition catalog. That makes the cadence a maintenance signal rather than a development one: the release rate tracks how fast the tracker ecosystem churns its domains and layouts, not how fast Jackett is building. The only structural movement is individual trackers migrating from scraped HTML to native APIs, which reduces the breakage surface where it happens.
◆ Prediction
Expect the daily definition-maintenance cadence to hold unchanged, since it is driven by external site churn rather than a roadmap. Further trackers moving to torznab or API key authentication would gradually cut the selector-repair volume.
Quay

Quay ships nothing but CVE remediation, mirrored across two supported branches
◆ Current state
Every entry in Quay's recent history is a security maintenance release, and they arrive as coordinated pairs — a 3.10.x and a 3.12.x tag cut hours apart carrying the same fixes cherry-picked to each branch. The content is dependency remediation against tracked advisories plus two SSRF hardening fixes, one in proxy cache upstream registry configuration and one in repository mirroring sources. No feature work appears in the window.
◆ Where it's heading
This is a registry in pure maintenance posture on its long-lived branches, with the release process itself automated down to changelog-bump commits. The recurring SSRF fixes across proxy cache and mirroring suggest a deliberate sweep through the code paths that fetch from upstream registries rather than isolated reports. Feature development, if it is happening, is landing on a branch this feed does not cover.
◆ Prediction
Expect the paired-branch cadence to continue at roughly the rate advisories land against the bundled Python and npm dependencies. The SSRF sweep looks close to complete, having now covered both proxy cache and mirroring.
