Mobile chrome safari not supported , curious why

I like the initiative but would love if there was a heavily stripped down version, it seems this one needs to download 95mb+. DuckDB also has a WASM version which is also not tiny but comes in at something like 36mb if I recall correctly.

Is the point of this privacy, offline analytics, or eliminating server costs, and does that survive the download cost of 95 megabytes?

People still complain about 95mb download in 2026. It's literally 2 minutes of 1080p youtube watching. Why bring server software to edge devices? Because its fucking awesome!

I appreciate that in global terms I live a life of data privilege, but I really don't think a 95mb download is any problem at all if the thing I'm downloading has utility.

Aside: nice /item?id= here on this submission! 48750000.

This is impressive! What's the stack? What drives the CLI-in-browser (libghostty?) What did you compile to wasm with (rust? zig? emscripten?)

Excited on what this brings to the server-side :)
