Or: don't hard-code your demo server port to 8080. Let it choose the next available port instead.

Instead of accessing your local dev servers through different port numbers, use Caddy to access them through separate domains.

Don't do this or you must go to bed without committing your code.

Unikernels can boot up rapidly and scale to zero to save energy and cost. A great basis for building efficient web-based tools.

Can multiple goroutines write to the same slice without any safeguard? Sure, they can, but is it a good idea?
