Thanks for making these, and sorry that Hacker News has so much of the “thanks I hate it” crowd. It’s a good thing you’re doing - especially to provide them without monetizing. Though one could generate these tools themselves if needed, the generated tools won’t be as refined as you’ve codified here and won’t be immediately available for use - they have to be generated!
The website is great and functional but if I may, it needs some tweaks so it matches the offer. Since the offering’s about doing less (no login, no upload) you’d be better to go with “less is more” on the feel, and only use animations - or interfere with scrolling - if such things truly add extra information. All the animations there now are decoration. The tools have no such decoration, and that causes dissonance.
Gonna be bookmarking this while wishing for a search engine that finds stuff like this instead of its SEOed out the wazoo compatriots. But maybe there’ll always be value in human curation.
