Restic precompiled stuff

Hello everyone,

I’m new in restic and golang. I want to find out if restic has some precomiled stuff e.g. libraries/binaries/etc which is provided as-is, mean it is under open license but is provided without sources
I walked across restic sources, but all projects I have found has source code and under an open license

Are there any non-opensourced packages utilized by restic?

Thank you in advance!
