What is Jackett?
Jackett ships daily, and every release is tracker definitions chasing sites that moved
Jackett cuts a release most mornings, each one a batch of indexer definition edits generated straight from the commit log. The work is uniform: new alternate domains for trackers that relocated, category mappings added or corrected, selectors repaired after a site changed its markup, and the occasional indexer removed when it goes dark. Recent releases also switched two trackers to API key authentication and added a public DHT crawler to another.
What is Liveblocks?
Liveblocks is rebuilding multiplayer collaboration around AI agents as first-class users.
Liveblocks shipped a six-week run of directional change: a brand-new React Flow SDK for collaborative node-graph editing, a Chat SDK adapter, a Feeds API explicitly framed for "Agent Workflows," a Python SDK for backend use, and v3.18 with breaking changes plus a mutateFlow() API that lets servers mutate diagrams from Node.js. The accompanying blog stream — "AI agents are becoming native users of software," feeds and APIs for agent workflows, n8n nodes — leaves no doubt about where the team is pointing. Underneath, the v1→v2 storage engine migration is in the long tail.

Jackett ships daily, and every release is tracker definitions chasing sites that moved
◆ Current state
Jackett cuts a release most mornings, each one a batch of indexer definition edits generated straight from the commit log. The work is uniform: new alternate domains for trackers that relocated, category mappings added or corrected, selectors repaired after a site changed its markup, and the occasional indexer removed when it goes dark. Recent releases also switched two trackers to API key authentication and added a public DHT crawler to another.
◆ Where it's heading
Nothing about the application itself is changing in this window — the engine is stable and the product is the definition catalog. That makes the cadence a maintenance signal rather than a development one: the release rate tracks how fast the tracker ecosystem churns its domains and layouts, not how fast Jackett is building. The only structural movement is individual trackers migrating from scraped HTML to native APIs, which reduces the breakage surface where it happens.
◆ Prediction
Expect the daily definition-maintenance cadence to hold unchanged, since it is driven by external site churn rather than a roadmap. Further trackers moving to torznab or API key authentication would gradually cut the selector-repair volume.
Liveblocks
4.4INFRA · APIS
Liveblocks is rebuilding multiplayer collaboration around AI agents as first-class users.
◆ Current state
Liveblocks shipped a six-week run of directional change: a brand-new React Flow SDK for collaborative node-graph editing, a Chat SDK adapter, a Feeds API explicitly framed for "Agent Workflows," a Python SDK for backend use, and v3.18 with breaking changes plus a mutateFlow() API that lets servers mutate diagrams from Node.js. The accompanying blog stream — "AI agents are becoming native users of software," feeds and APIs for agent workflows, n8n nodes — leaves no doubt about where the team is pointing. Underneath, the v1→v2 storage engine migration is in the long tail.
◆ Where it's heading
Liveblocks is no longer just "realtime presence and comments for documents." It is positioning itself as the substrate where humans and AI agents share state — diagrams, chat threads, feeds — with the same primitives. The room.history.disable() API for hiding agent-generated writes from the undo stack is the small detail that gives the strategy away: the team is designing for a world where most edits in a room come from agents, and humans need to be shielded from that noise.
◆ Prediction
The next two minors should bring more agent-shaped APIs (auth scoping for agents, read-only agent participants, server-driven LiveObjects mutations from non-Node runtimes) and broader framework adapters beyond React Flow and Handsontable. Expect Liveblocks to pitch the Chat SDK adapter as a path off OpenAI's hosted threads when teams want agent conversation state stored on their own infra.
