The website doesn’t tell me why I would use this instead of just Rolldown.

The “What is tsdown” link goes to a video with pre-roll ads.

I put the video URL into Gemini and asked it what it does. Gemini hallucinated a comparison with Rspack.

I followed the link to documentation from the YouTube description and it took me back to the main page that does not have a description of what it does.

There is an FAQ with a single question:

> Will tsdown support stub mode (similar to unbuild)?

Is there any kind of text description available for what this is and why I – as somebody who is currently writing a lot of front-end code – should care?
