Cosmic vs Jackett
A side-by-side editorial comparison of Cosmic and Jackett — release velocity, themes, recent moves, and the top alternatives to consider.
Cosmic vs Jackett: at a glance
What is Cosmic?
Cosmic retired AI Studio and gave its agents goals — the CMS is becoming an agent runtime.
Six weeks of releases pull in one direction. AI Studio was retired and Cosmic's AI consolidated into three surfaces: Agents, Workflows, and Code. Agents gained goals described in plain language that they work toward on their own, running steps and checking in, plus write access to reusable rich-text Content Blocks rather than read-only reference. Semantic search embeds bucket objects into a vector index so content is retrievable by meaning. The two newest entries add Claude Opus 5 and Kimi K3 to the model lineup.
What is Jackett?
Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.

Six weeks of releases pull in one direction. AI Studio was retired and Cosmic's AI consolidated into three surfaces: Agents, Workflows, and Code. Agents gained goals described in plain language that they work toward on their own, running steps and checking in, plus write access to reusable rich-text Content Blocks rather than read-only reference. Semantic search embeds bucket objects into a vector index so content is retrievable by meaning. The two newest entries add Claude Opus 5 and Kimi K3 to the model lineup.
◆ Where it's heading
The content API is turning into a runtime agents operate inside: goals instead of prompts, write permissions instead of suggestions, and a vector index so an agent can find what it needs without being handed it. Retiring AI Studio is the clearest signal — Cosmic is choosing fewer, deeper surfaces over a menu of separate AI features, which is a harder position to reverse.
◆ Prediction
Expect agent write scope to extend past Content Blocks to objects and media, and goals to gain triggers or schedules so they run without a person starting them.
Jackett
5.0INFRA · APIS
Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.
◆ Current state
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.
◆ Where it's heading
The work is entirely maintenance. Its value depends on keeping up with a tracker ecosystem where sites change domains and layouts weekly. Where possible, the project is moving definitions to sturdier integrations, such as switching world-of-tomorrow to its Torznab API and retiring trackers that moved to direct downloads.
◆ Prediction
Expect the daily cadence to continue, with more trackers moved to API-based definitions and more dead sites removed. Core changes stay rare.
