A native Mac download manager. Drop in an NZB, walk away.
Just a Mac app that gets out of your way.
Drop an NZB and walk away. NZBolt downloads your files, checks them with PAR2, repairs anything damaged, extracts the archives, and puts everything in your destination folder.
A real Mac app. Light and dark mode, keyboard shortcuts, Dock integration, system notifications. Not a browser tab. Not an Electron wrapper.
Quit mid-download, lose power, force-restart — NZBolt picks up exactly where it left off. Failed parts retry automatically across your servers.
Add primary and backup Usenet servers. Set connection limits and priorities for each. SSL/TLS built in. Credentials stored in your Keychain.
Full speed by default. One click to throttle when you need your bandwidth back.
No Python. No Java. No web server. One app bundle with everything included — par2, unrar, 7-Zip, all signed and ready to go.
Five stages. No manual steps.
Drag and drop, open from Finder, or use a watched folder
Fast, parallel downloads from your Usenet servers
PAR2 integrity check with automatic repair
RAR, 7z, and ZIP — including password-protected
Files moved to your destination folder, temp files cleaned up
Track all your downloads at a glance. Sort by status, progress, speed, or ETA. Active jobs rise to the top. Switch between queue and history in one click.
Select a job to see exactly what's happening. Pipeline progress as a visual stepper, the full file list, and any errors — all in a slide-out inspector pane.
Add unlimited Usenet servers. Test connections inline, configure SSL/TLS, set priorities for primary and backup servers, and manage credentials — all stored securely in your system Keychain.
No compromises. No wrappers. No web views.
Built in Swift 6 with strict concurrency — zero data races, enforced at compile time.
Backed by SwiftData. Downloads resume exactly where they left off.
Native NNTP over TLS using Apple's Network.framework.
arm64 native. No Rosetta translation. Built for M-series Macs.
yEnc decoding via SIMD-accelerated C++ — not interpreted, not scripted.
Unit tests, UI tests, and end-to-end integration tests against real servers.
A decade passed, macOS moved on, and one day it just didn't launch anymore. The alternatives work, but they either need a runtime, run in a browser, or don't feel like a Mac app.
I didn't need a hundred configuration options or a remote API. I just wanted to drop in an NZB file and have it handled. So I built NZBolt. A native Mac app, from scratch, no compromises.
One app. No runtime. No setup. Download NZBolt, add your server, done.
