Dragonfly vs Jackett: at a glance
What is Dragonfly?
Dragonfly tags v2.0.0 while hardening memory accounting and patching a HyperLogLog CVE across the 1.x line
Dragonfly is shipping across two concurrent tracks: the 1.40.x stable line is receiving steady improvements to connection memory accounting correctness, tiering metrics, and Redis ecosystem compatibility (RedisShake RDB format), while v2.0.0 has been tagged. The 2.0.0 entry's visible content is minimal — scope-based memory tracking is added but disabled — suggesting 2.0.0 is an architectural milestone marker for accumulated work rather than a single user-visible feature introduction.
What is Jackett?
Jackett in pure tracker-maintenance mode, daily domain and category updates only
Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.

Dragonfly tags v2.0.0 while hardening memory accounting and patching a HyperLogLog CVE across the 1.x line
◆ Current state
Dragonfly is shipping across two concurrent tracks: the 1.40.x stable line is receiving steady improvements to connection memory accounting correctness, tiering metrics, and Redis ecosystem compatibility (RedisShake RDB format), while v2.0.0 has been tagged. The 2.0.0 entry's visible content is minimal — scope-based memory tracking is added but disabled — suggesting 2.0.0 is an architectural milestone marker for accumulated work rather than a single user-visible feature introduction.
◆ Where it's heading
The project's operational focus is sharpening around production reliability and Redis compatibility: O(1) connection memory tracking, per-shard tiering metrics, CVE-2025-32023 remediation in HyperLogLog, and AVX2/NEON SIMD acceleration for dense HLL operations (8-29x measured gains). The staged 2.0.0 release and the disabled scope-based memory tracking point to Dragonfly building toward granular per-connection memory visibility as a differentiating feature for operators running large clusters.
◆ Prediction
Scope-based memory tracking will be re-enabled in a near-term 2.x patch — the code is already shipped in 2.0.0, just gated off. That re-enable will be the actual headline for what 2.0.0 unlocks operationally.

5.0INFRA · APIS
Jackett in pure tracker-maintenance mode, daily domain and category updates only
◆ Current state
Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.
◆ Where it's heading
The last 10 entries show no feature development — every commit is tracker registration data. Jackett's trajectory is entirely reactive to the torrent ecosystem: trackers move domains, change engines, and die; Jackett follows. There is no observable product initiative in this window.
◆ Prediction
The entries don't support a confident prediction about new feature direction. Daily tracker maintenance will continue as the primary output; any substantive change would come from outside this pattern.
