Bun is deprecated in the video downloader “yt-dlp,” with the decision based on the risk of Bun being overly focused on AI coding

yt-dlp has effectively deprecated Bun, supporting only a limited version range going forward.

Deno remains the preferred runtime, while QuickJS and other options are also in the mix.

The maintainers cited security concerns and uncertainty around Bun’s future direction.

They also pointed to Bun’s move toward AI-assisted development and a Rust rewrite as maintenance risks.
