theoretically there is a go port of sqlite by either using wazero[1] (wasm runtime) and then using sqlite from there or some modernc package[2](i am not sure what this website is except for the sqlite part, so maybe someone can clarify that though) There was also this wrapper of sorts to make the wazero thing genuinely easier to do and it was on r/golang but I don't remember its name but I do think it is semi popular.

There is a CGO-free package for the basics: https://gitlab.com/cznic/sqlite

Not 100% drop-in though. I’ve hit some snags around VFS support.

Define cross platform here?

I’ve heard this complaint but have yet to have an issue deploying to Linux/MacOS/Windows on arm or x86 using CGO backed libraries.

Maybe if you truly are targeting some niche platform but then you likely have some other issues to contend with and where are you deploying to?
