Nidestream

The download manager for Mac

Faster downloads that resume where they stopped, carry on from a fresh link when the old one expires, and come straight from your browser, videos included.

Install

Nidestream isn't notarized by Apple yet, so macOS asks you to approve it once.

Drag it to Applications

Open Nidestream.dmg and drag Nidestream onto the Applications folder.

Approve it once

Open Nidestream and click Done on the warning. Then open System Settings → Privacy & Security, click Open Anyway and enter your password.

Connect your browser

Nidestream shows you how to add its extension to Chrome, Brave, Edge or Firefox. After that, downloads you start in the browser go to Nidestream.

Browser extension

Hands your browser's downloads, links and videos to Nidestream. It talks only to the app on your own Mac.

Chrome Web Store: coming soon Firefox Add-ons: coming soon

Works in Chrome, Brave, Edge, Arc, Vivaldi, Opera and Firefox. Until the store listings are live, open Nidestream and follow Connect Your Browsers to add it.

What it does

Everything you'd expect from a download manager like IDM, built for the Mac.

Faster downloads

Splits files across several connections and adds more only while they make the download faster.

Resume anything

Pause, lose the connection, or quit: downloads continue where they stopped.

Fresh links, same download

When a link expires, click it again in the browser and Nidestream carries on from where it was.

Video grabber

Finds the videos and streams a page plays, and saves streaming video as a single file.

Queue and scheduler

Download later, at night, or a few at a time, then sleep or shut down when the queue is done.

Organised and in control

Categories with their own folders, a speed limiter, batch and whole-site downloads, and a menu bar view.
