Jackett vs Casdoor: at a glance
What is Jackett?
A daily-shipping indexer proxy whose entire product is a scraper definition file that never stops rotting.
Jackett ships a tagged release essentially every day, and every one of them is the same shape: tracker selectors updated, domains bumped, categories added, dead sites removed. The release notes are auto-generated commit lists with no prose. The C# application itself is stable; what changes is the YAML definition corpus that keeps a few hundred torrent trackers reachable through a single Torznab endpoint.
What is Casdoor?
Nine releases in four days, all of them small — Casdoor is grinding on tenant-level governance.
Casdoor is running an unusually tight release train: nine tagged versions between August 1 and August 4, each carrying one or two commits. The content clusters around two areas. Retention and expiry are becoming per-organization settings — configurable record retention days, configurable token retention days, and automatic permission revocation after a set expiry. Separately, OAuth conformance work continues, with the RFC 8707 resource parameter now preserved through both the consent flow and the fast auto-signin path, plus a backchannel logout URL field on the application edit page.

Jackett
5.0INFRA · APIS
A daily-shipping indexer proxy whose entire product is a scraper definition file that never stops rotting.
◆ Current state
Jackett ships a tagged release essentially every day, and every one of them is the same shape: tracker selectors updated, domains bumped, categories added, dead sites removed. The release notes are auto-generated commit lists with no prose. The C# application itself is stable; what changes is the YAML definition corpus that keeps a few hundred torrent trackers reachable through a single Torznab endpoint.
◆ Where it's heading
This is maintenance-as-product, and the cadence is a symptom rather than a sign of momentum: trackers move domains, add anti-bot checks, and change markup, so the definitions decay continuously and the fix rate has to match. The visible trend across these releases is attrition — torr9, rockbox, rain, runtheframes, torrentleech-pl and elitetorrent-wf all removed in a single fortnight — partially offset by category expansion on the trackers that survive.
◆ Prediction
Expect the daily definition-churn cadence to continue unchanged, with the removal list growing faster than the addition list. Nothing in these entries indicates work on the application core.
Casdoor
5.0INFRA · APIS
Nine releases in four days, all of them small — Casdoor is grinding on tenant-level governance.
◆ Current state
Casdoor is running an unusually tight release train: nine tagged versions between August 1 and August 4, each carrying one or two commits. The content clusters around two areas. Retention and expiry are becoming per-organization settings — configurable record retention days, configurable token retention days, and automatic permission revocation after a set expiry. Separately, OAuth conformance work continues, with the RFC 8707 resource parameter now preserved through both the consent flow and the fast auto-signin path, plus a backchannel logout URL field on the application edit page.
◆ Where it's heading
The per-organization retention and expiry settings point at multi-tenant deployments where each tenant carries its own compliance obligations — a single global retention policy stops working once one organization's auditor wants 90 days and another's wants 400. The RFC 8707 work is narrower but pointed: resource indicators bind a token to the API it was issued for, which matters when one identity provider fronts many services. A batch UpdatePermissions API added to cut Casbin enforcer rebuilds suggests some deployments are large enough that permission writes had become a bottleneck.
◆ Prediction
The retention-and-expiry pattern is not finished — record and token retention are now per-organization, and other lifecycle settings are the obvious next candidates. Expect the release cadence to stay at this granularity, since these tags carry single commits rather than batched releases.
