Jackett vs Prowler: 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 Prowler?
Prowler is turning its scanner into an agent that can operate the platform, and charging for it.
Prowler ships roughly weekly, alternating feature minors with patch releases of API, UI and SDK fixes. The dominant thread across the last two months is Lighthouse AI, which went from a chat assistant reading findings (5.33.0) to one that takes actions (5.35.0) to one that reaches every tool family the Prowler MCP server exposes, including users and roles (5.37.0). Around it, the platform side has been filling in security-operations workflow: findings triage with lifecycle states, Jira dispatch for finding groups, and Attack Paths query tracking.

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.
Prowler
8.8INFRA · APIS
Prowler is turning its scanner into an agent that can operate the platform, and charging for it.
◆ Current state
Prowler ships roughly weekly, alternating feature minors with patch releases of API, UI and SDK fixes. The dominant thread across the last two months is Lighthouse AI, which went from a chat assistant reading findings (5.33.0) to one that takes actions (5.35.0) to one that reaches every tool family the Prowler MCP server exposes, including users and roles (5.37.0). Around it, the platform side has been filling in security-operations workflow: findings triage with lifecycle states, Jira dispatch for finding groups, and Attack Paths query tracking.
◆ Where it's heading
The open-source CLI scanner is becoming the data layer for a paid agentic product. The 5.34.0 renaming made the split explicit — Prowler CLI and Prowler Hub stay open, while Cloud, Private Cloud, Lighthouse AI and MCP are the commercial surface — and every Lighthouse release since carries a subscription-only note. The technical bet is that RBAC is a sufficient safety boundary for an agent: Lighthouse can do whatever the asking user could do, which is what allows it to be handed administrative tools rather than read-only ones.
◆ Prediction
Expect the next Lighthouse releases to push into unattended operation — scheduled or event-triggered agent runs rather than chat-initiated ones — since scan scheduling and alert rules are now inside its reach. Continued patch releases fixing Attack Paths graph behaviour on Neo4j and Neptune suggest that subsystem is still settling.
