That’s not the Dillo webpage anymore. There is a whole history behind this but the link is now this https://dillo-browser.github.io/
The dev was at FOSDEM a few weeks ago too https://www.youtube.com/watch?v=sFJp8JDg8Yg
I think Dillo is a great project. The whole thing fits on a diskette. Crazy.
Dev is on fedi too
