Is that a fork of openPGP or some other product that is based on the same specs? I could not find anything meaningful for openGPG.

That's because it doesn't have open in its name, it's called GPG or GnuPG.

It's another product based on the same specs.

OpenPGP is not a product, it's a standard.

Maybe you're thinking of https://sequoia-pgp.org/ or https://neopg.io/ ?
