What each one is
Lux
Lux is a video downloader you run from the terminal. You give it a web page address, and it finds the video streams on that page and saves them to your computer. It can also be used as a Go library by other programs. The README describes it as fast and simple, and it lists quality choices, playlist support, and resume after interruption.
social-auto-upload
social-auto-upload is a Python tool that publishes videos, articles, and image posts to social media platforms such as Douyin, Xiaohongshu, Bilibili, YouTube, and TikTok. It offers a unified `sau` command line and packaged skills that AI agents such as Codex, OpenClaw, or Claude Code can use. People use it to avoid repeating the same upload steps on each platform.

Not ideal for
Lux
- People who prefer a graphical app, since the README describes only command-line usage
- Anyone needing a site not on the supported list, since the README says unsupported URLs are only attempted as direct file downloads
- Users who need merged audio and video output without installing FFmpeg, since the README lists FFmpeg as a required separate dependency for merging
social-auto-upload
- People who want a point-and-click app with no terminal use, since the README centers on CLI commands and install docs
- Users needing platforms not listed in the README's support table
- Anyone expecting guaranteed stability on platforms marked as in development or experimental, such as YouTube scheduling and Zhihu scheduling
Trade-offs
Lux
- Requires FFmpeg installed separately for final file merging
- Some site support is noted as known issues in the README, such as certain Youku and Xigua/Toutiao videos
- Site support depends on the project keeping up with changes on each website, which the README does not detail
social-auto-upload
- Relies on logging into each platform and maintaining local sessions, which can break when platforms change
- README mixes stable features with in-development and experimental ones, so support must be checked per platform
- The README contains sponsor messages that are unrelated to the tool's function
