I looked into this but Go on a little OpenWrt router seemed… silly.

If you’re interested in something lightweight for OpenWrt give this a try:

Why? Go compiles to distributable binaries, Go binaries do not depend on Go to run. You wouldn’t need to actually install Go on the router

From their own documentation [1]

> The dnscrypt-proxy file is quite large, but can be compressed for a massive reduction of its size, from ~12 Mb down to ~2 Mb.

Routers typically have 8-16 Mb of storage. Even 2 Mb is a bit much but even if the size doesn’t bother you the memory usage is still relatively extreme when compared to the link I shared.

Sure that’s fair, not really specific to Go though

Go specifically makes a bunch of choices that lead to (somewhat, it's by no means extreme) larger executables. Which is fine, but means it's not the best choice for the specific usecase of targeting tiny devices.

Get a better router, there's no excuse for openwrt these days, with plenty of ultra small, cheap, abundant devices that can run a full distribution without issues.
