FluxGrab
A free Windows app for saving YouTube videos and Instagram Reels to your computer, up to 4K. Paste a link, pick a quality and download, with no ads and no account.

The challenge
Saving a video usually means an online downloader full of ads and pop-ups, a browser extension, or a command-line tool with options that are hard to remember.
The solution
FluxGrab is one desktop window with a YouTube tab and an Instagram tab. It detects the link, lists the available formats, shows progress and speed while it downloads, and opens the folder when the file is ready. A short guide is built into the app.
