What is Jackett?
Jackett's daily tags keep chasing tracker sites, two indexer edits at a time
Every release in this window is a handful of indexer definition edits: a config note about IP filtering on newstudio and IPv6-only handling for anisource in the newest tag, and before it a steady run of domain bumps, trackers added and removed, and category mappings corrected. The bodies are auto-generated commit lists.
What is Knock?
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

Jackett's daily tags keep chasing tracker sites, two indexer edits at a time
◆ Current state
Every release in this window is a handful of indexer definition edits: a config note about IP filtering on newstudio and IPv6-only handling for anisource in the newest tag, and before it a steady run of domain bumps, trackers added and removed, and category mappings corrected. The bodies are auto-generated commit lists.
◆ Where it's heading
This is maintenance as a product. Trackers move domains, change authentication, or disappear, and Jackett ships a tag the same morning; Scenetime was added and dropped within days, 720pier removed and restored by revert. Nothing in the release stream suggests work on the application itself rather than on the definitions it carries.
◆ Prediction
Expect the same daily cadence of indexer edits, with the churn concentrated on domain changes and authentication method switches.
Knock
6.3INFRA · APIS
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
◆ Current state
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
◆ Where it's heading
Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
◆ Prediction
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
