NeoDLP
NeoDLP is a free, open-source downloader for video and audio, available for Windows, macOS, and Linux. The project says it supports thousands of websites, including YouTube, Facebook, Instagram, and X. It handles individual videos, playlists, and batch downloads, and can combine selected video and audio streams. Output choices include MP4, WEBM, MKV, MP3, and other selectable formats; options can embed subtitles, chapters, information, and thumbnails. NeoDLP Library helps organize downloads, and Chrome and Firefox integrations are available through a separate extension. Other listed features include SponsorBlock, Aria2, proxy and rate controls, and customizable settings. Desktop requirements listed are Windows 10/11, macOS 11 or later, and modern Linux distributions. Installation options include system-specific packages as well as WinGet, Homebrew, Flathub, and AUR. The maker warns that experimental macOS ARM64 browser downloads are unsigned and recommends Homebrew or its command-line installer for Apple Silicon. The project says users should download only content they own or are authorized to download and follow applicable laws and source-platform terms.
