Catch is a lightweight macOS utility that sits in your menu bar and automatically manages RSS/Atom torrent feeds, turning your Mac into a hands-off broadcast receiver for the content subscriptions you care about.
What is Catch?
Catch is a dedicated broadcatching client for macOS — a term that describes the practice of subscribing to torrent feeds (TV shows, podcasts, software releases) so that new episodes or files download the moment they appear, without any manual searching. Think of it as a TiVo for your torrent workflow: you wire up a feed once and forget about it.
The app lives entirely in the menu bar, staying out of your way until something worth your attention happens. There are no windows to babysit, no dashboards to check. It polls your configured feeds on a schedule and hands matching torrents off to whatever torrent client you already use — Transmission, qBittorrent, uTorrent, or even a custom watch folder.
What does Catch do best?
Catch excels at silent, automated torrent-feed management with near-zero ongoing friction. Once you paste in a ShowRSS, Flexget, or any standards-compliant RSS/Atom feed URL and define a filter, the app does the rest entirely in the background.
- Feed subscriptions with per-feed filters — regex or keyword rules mean only the quality tier or episode range you actually want ever reaches your download client.
- Multiple client integrations — hand-off works with Transmission (via its RPC interface), a watch folder, or a custom URL scheme, so it plugs into whatever you already have.
- Menu bar badge notifications — a subtle count badge or Notification Center alert surfaces new downloads without interrupting your workflow.
- Minimal CPU and memory footprint — it is genuinely idle between polls; I have run it for months without ever noticing it in Activity Monitor.
Where Catch pulls ahead of running a full application like Sonarr or Radarr is simplicity. Those tools are powerful but require a local server, a web UI, and ongoing maintenance. Catch is an app you install and configure in five minutes.
Is Catch free?
Catch is free to download directly from the developer's site. There is no paid tier, no subscription, and no feature gate — the full experience is available from the first launch. The project is maintained by an independent developer, Giorgio Calderolla, and has been a fixture of the Mac utilities scene for years, which speaks well of its staying power for a free tool.
Who should use Catch?
Catch is ideal for Mac users who already have a torrent client configured and want to automate the "check for new episodes" step they currently do by hand. If you subscribe to public RSS feeds for TV series, open-source software releases, or Creative Commons audio, Catch turns that into a hands-free pipeline.
It is not the right tool if you need a full media-server stack with library management, metadata scraping, and a Plex-style UI. For that, Sonarr, Radarr, or Flexget with a full configuration are better fits. Catch occupies the space between "doing it all manually" and "running a self-hosted server," which is exactly the right slot for a power user who values simplicity.
Developers and sysadmins who subscribe to software release feeds — Linux ISOs, open-source project torrents — will also find it useful as a lightweight watch mechanism.
What are the best Catch alternatives?
The closest direct alternative on macOS is nzb-o-matic or manual cron-job scripting with Flexget, though neither has Catch's native menu-bar integration. Sonarr and Radarr are the obvious heavy-hitters, but they require Docker or a local server process and are overkill for a hobbyist feed or two. For pure simplicity in the menu bar, nothing on Mac matches Catch's balance of capability and minimalism. Some users route feed URLs directly into Transmission's built-in RSS watcher, but Catch gives you finer per-feed filtering and a more transparent notification surface.
How does Catch compare to Sonarr?
Sonarr is a rack-mount appliance; Catch is a Swiss Army knife. Sonarr indexes every episode of every show you track, manages quality upgrades, integrates with Jackett for hundreds of indexers, and writes to a full media library. Catch watches feeds you explicitly subscribe to and hands matching torrents off to your existing client — nothing more, nothing less.
For a single person tracking a handful of ongoing shows, Catch wins on setup time and system resources by a wide margin. For a household media server or anyone managing dozens of series with quality-upgrade logic, Sonarr is the correct choice and Catch will feel limited.
