OwlbinmacOS download manager · buy once
Owlbin is a download manager for people who keep things. It renames every file to your convention, sorts it into the right folder, and skips what you already have — before the download even finishes.

The idea
A normal download manager hands you video(3).mkv in your Downloads pile. Owlbin resolves a naming template from the URL, the site, the metadata and the date, files it by your rules, and fingerprints it so duplicates never land twice.
The filename is decided the moment the download starts — not something you fix by hand later, for the hundredth time.
Extension, host, keyword or regex rules route each file to its folder as it completes. First match wins.
An oshash from the first and last 64 KB is matched against your library before a single byte is downloaded.
The engine is built in-house — no aria2, no GPL entanglement, no telemetry. It runs entirely on your machine.
What you're paying for
Compose filenames from tokens — site, title, date, sequence, query values, metadata. Set it once; every download obeys.
Change your mind at 42%. Type a new name and it lands under the new one — no restart, no re-download, no leftover .part.
Rules sort each finished file into the right folder automatically — by extension, host, filename or regex, evaluated top to bottom.
Owlbin computes an oshash from the head and tail of the file and checks your local index — so you never download the same thing twice.
For 1,000+ supported sites it pulls title, uploader, upload date and resolution, and feeds them straight into your template.
Detects a studio catalog code in the URL or name and fills in title, performer, studio and release date from your own metadata scraper.
And the rest of the job
The curation is the reason to switch. This is the reason you can stop running three other apps.
Segmented HTTP with resume across restarts. Built from scratch — no bundled aria2.
A universal libtorrent helper (Apple Silicon + Intel) drives torrent downloads through the same queue.
Right-click a link or catch normal downloads and send them straight to Owlbin.
Cap the bandwidth and how many run at once — smooth enough to keep working through a video call.
Fully localized, from English and Japanese to German, French, Spanish and Chinese.
Signed, EdDSA-verified updates arrive quietly in the app. No App Store required.
