Built with .NET 10 and RazorConsole.

Features

• Download audio (MP3) or video (MP4) from YouTube, TikTok, Instagram, Facebook, and 1000+ sites
• MP3/MP4 format toggle
• Auto-downloads yt-dlp and ffmpeg on first run (no manual setup)
• Keeps yt-dlp up to date automatically, so sites do not start refusing downloads as it ages
• Native folder picker to change download location
• Cross-platform: Windows, Linux, macOS
• Keyboard-driven TUI with animated spinners

Installation

Option 1: .NET Tool (requires .NET 10 SDK)

dotnet tool install -g Naptrack

Then run from anywhere:

naptrack

Option 2: Standalone Binary (no dependencies)

Download the latest release for your platform from Releases. No .NET installation needed.

Or build it yourself:

# Windows
dotnet publish -r win-x64

# Linux
dotnet publish -r linux-x64

# macOS Intel
dotnet publish -r osx-x64

# macOS Apple Silicon
dotnet publish -r osx-arm64

The output is a single executable in bin/Release/net10.0/<runtime>/publish/.

Usage

1. Launch naptrack
2. Paste a URL (YouTube, TikTok, Instagram, Facebook, etc.)
3. Select MP3 or MP4
4. Press Enter or Tab to [ Download ] and press Enter
5. File downloads to your configured folder

Keyboard Shortcuts

Configuration

• Download folder: Click the folder path or use [ Change ] to open a folder picker
• The URL box empties as soon as a download is accepted, so it is ready for the next link. The link is not lost — press ↑ to bring it back from history if a download needs another go.
• Settings are saved to:
  • Windows: %APPDATA%\Naptrack\config.json
  • Linux: ~/.config/Naptrack/config.json
  • macOS: ~/Library/Application Support/Naptrack/config.json

Dependencies

Naptrack automatically downloads these on first run if not found:

• yt-dlp — media extraction from 1000+ sites
• ffmpeg — audio/video format conversion

They live alongside your settings, in bin/ next to config.json.

Keeping yt-dlp current

yt-dlp is the part of Naptrack that goes out of date. Sites change what they accept on no schedule, and an old build fails in a way that looks like being blocked: the video is found and its formats are listed, then the download itself comes back HTTP Error 403.

So Naptrack tracks yt-dlp's nightly channel — the same code that becomes the next stable release, published as it lands — and checks for a newer build at most once a day, updating in the background while it starts. If you are offline, rate limited, or already current, nothing happens and nothing is said.

The version in use is shown in the app. It turns yellow once the build is more than two weeks old, and [ Update yt-dlp ] next to it fetches the newest build immediately. That button is what the "Access denied" message is pointing you at.

If you already have yt-dlp installed through pip, Homebrew or a package manager, Naptrack uses it and leaves it alone — updating someone else's install is not its business. The exception is a system copy that has gone stale: rather than leave you with downloads that cannot succeed, Naptrack installs its own up-to-date copy and uses that instead. Yours is left untouched.

JavaScript runtime (optional)

YouTube's player challenges are JavaScript, and yt-dlp now warns that extracting without an engine to run them is deprecated and may drop some formats. yt-dlp finds Deno by itself; Naptrack additionally detects Node or Bun and points yt-dlp at whichever it finds. None of them are required, and installing one is not a fix for being blocked — it affects which formats are available, not whether the download is allowed.
