zitadel VS Mailcow

Im one of the authors of ZITADEL the open source identity and access management solution.

An other Keycloak alternative would be our (I am one of the founders) project ZITADEL.

You could take a look at https://zitadel.ch/ Or curity https://curity.io/product/

I'm biased since I work for ZITADEL (https://github.com/caos/zitadel). Passwordless with FIDO2 has been baked in since the beginning. I reckon that the major Open Source alternatives provide support as well. FIDO2 should work on all major OS and browsers.

And a bigger project i know is zitadel (https://github.com/caos/zitadel)

Full disclosure: My company is building ZITADEL, an open source alternative for Auth0 or Keycloak (both still very good, with some drawbacks). https://github.com/caos/zitadel/

We are building a cloud-native IAM over here https://github.com/caos/zitadel

It is written in Go and built around event sourcing for a great audit trail. We already support OIDC, Passwordless, RBAC and working on more features each day.

For those who want to run it on-prem we have a kubernetes operator ready in the next few weeks who also manages the database (cockroach).

We run our own service here https://zitadel.ch with a free tier as well

Feel free to engage with us on GitHub discussions.

I'm not sure if it makes sense to build your own oauth/oidc server. It's fun to learn all these techniques but you have to maintain much more code. You also have to implement security mechanisms from dev and ops perspectives. There are existing implementations. If you want to check out an existing open source implementation in go you could take a look at the implementaion of my company called zitadel. I would love to answer question if there are any.

I've been running mailcow [1] on a Hetzner cloud server for a few years and am pretty happy with it.

I have been searching for a self-hosted suite similar to Google Worksuite. I found the following: 1. Mailcow - https://mailcow.email/

Yes, I switched to mailcow (https://mailcow.email) and installed Roundcube via the excellent tutorial (https://docs.mailcow.email/third_party/roundcube/third_party-roundcube).

I've heard good things about mailcow

https://mailcow.email/

You can self host email if you really want to, but it's really more trouble than it's worth. If you do self host, you have to worry about the consequences of missed emails if your server or Internet ever goes down, and you'll have to use someone else's SMTP server if you don't want your emails to go directly to spam. The cheapest good SMTP server is Amazon SES, which I believe is $0.10 per 10k emails. I've been looking into mailcow for self hosting an email server and it seems the best way to go.

However, https://mailcow.email/ is the ONLY exclusion I make for that. As it's an all in one docker managed solution. Where the only things you have to worry about is the reputation of your mailing IP.

But its probably easier to use a dockerized container with all the mail stuff integrated and pre-setup like: https://mailcow.email/

If you're looking for a full solution that I haven't tried (due to resources) try: MailCow. Good luck.
