zitadel VS Pomerium

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.

Option 3: Pomerium might be an alternative as well.

That is not how you do Zero Trust. You want to use an Identity Aware Proxy. There are lots of ways you can implement this with Google as your core auth. For example Pomerium or oauth2-proxy.

I’m really surprised this sub has no love for Pomerium. I feel like it’s as simple as Caddy with all the security benefits of Traefik.

I am not sure if I understand how Pomerium works (or any identity-aware proxy).

Pomerium sidecar.

Just want to drop https://www.pomerium.com/ here. We use it at our company with ~1500 people with many apps behind the proxy. It also supports JWT for the backend, so you can integrate your apps easily without having to worry about the OAuth flow and also your apps are protected from random internet attacks.

You’ve got to protect. Anonymity is not going to work. Pomerium is another option in addition to those already suggested. https://github.com/pomerium/pomerium

I am currently looking at Wireguard/Tailscale (Wireguard based) options - early days for me so far. Also planning to look at something like Pomerium for a zero trust approach. https://www.pomerium.com/
