    Project mention: HTML Can Do That | news.ycombinator.com | 2026-08-20

    I'm currently in the process of taking a lot of risk rewriting a large-ish app that I maintain to fully eliminate the use of frontend frameworks (and the larger JS ecosystem in general) and to switch to simple SSR + semantic HTML and CSS.

    Using this tiny lib [2: shameless plug] I wrote specifically incorporating the "HTML Can Do That"-style realisations going into the big rewrite.

    Project mention: LiftKit – UI where everything derives from the golden ratio | news.ycombinator.com | 2026-02-09

    The CSS is in the github repo here: https://github.com/Chainlift/liftkit

    LiftKit's free forever to anyone. It's just early stages and bad.

    The idea was that if a company wanted to hire us for direct support, we'd do that. But the problems are: [A] no enterprise in their right minds would use this thing in its current state and [B] "us" is me and I don't have time to do that anymore
