List of GnuPG/OpenPGP replacement (not OpenPGP compatible)

https://github.com/wbl/cpgb CPGB is the Curve Privacy Guard B, a secure replacement for GPG using ECC. (Status: Dead? last-update:2011)
https://github.com/carlos8f/salty Alternative public key encryption using NaCl. (Status: Dead? last-update: 2016)
https://github.com/TotalTechGeek/DiscreteCrypt This tool is an alternative to software like PGP, with a focus on Discrete Log Cryptography. The algorithm is currently in v2.2.5. (Status: Active)
https://saltpack.org/ a modern crypto messaging format (Status: Active)
https://github.com/stealth/opmsg opmsg is a replacement for gpg which can encrypt/sign/verify your mails or create/verify detached signatures of local files. (Status: Active)

List of GnuPG replacement (OpenPGP compatible)

https://github.com/das-labor/neopg - https://neopg.io/ " The multiversal cryptoengine!" (Status: Active (Alpha))

identitykit can be used similarly to minisig https://github.com/devguardio/identity#file-signatures
but it can also be used as a TLS CA, and for encryption and has quorum-signatures for allowing multiple users to sign files as an organization

NeoPG looks dead - also the domain now owned by something very unrelated to PGP completely ;)

AGE ("actually good encryption", bold name) is another standard. It has two main implementations, the reference in golang (https://github.com/FiloSottile/age) and the other one in rust (https://github.com/str4d/rage).

https://sts10.github.io/2021/09/06/exploring-age-1-point-0.html looks like a good primer.
