VoidAuth is simpler to setup/use than Authentik for sure, but of course Authentik has more features. They both support proxy-auth, OIDC, and have user management UIs so in that way they are similar. I like VoidAuth for its simplicity but you can always run both and decide, if you have any questions about setup I will try to answer!

I have never used nforwardauth, but it looks like it offers a subset of the functionality of VoidAuth. Both support proxy-auth, but VoidAuth has user management features and also supports OIDC, passkeys, etc. I think nforwardauth looks like a great project, you can always setup VoidAuth alongside and try it out!

I would not recommend using VoidAuth to anyone who needs to be any kind of security compliant. I am not a security professional and am using packages for the OIDC and other security heavy-lifting. I can recommend VoidAuth for those just looking for a simple but good looking auth app for securing their own selfhosted apps and resources.

My previous setup was with Authelia and lldap, and VoidAuth is heavily inspired by a combination of both. I think the advantages VoidAuth has are simple user management, supporting user registration/invitation, more branding customization, and a better end-user UI (imo).

There are other great selfhosted auth solutions such as Authelia and lldap, and also Authentik, Keycloak, pocket-id, and Rauthy. I would encourage anyone looking for a selfhosted auth solution to shop around!

Let me know how it goes!
