Has anyone used Keycloak for actual production? I have often thought about it but I stick to Auth0 just because I don't know if Keycloak has a good track record?

You might be interested in some of the presentations at KeyConf[0]. You can also get some real world stories from the Reddit[1].
I was at KubeCon EU this year (representing my employer, FusionAuth) and there were lots of folks who were running Keycloak who came and chatted with us.
It's a different set of tradeoffs than Auth0 or other SaaS services. More control, but more responsibility too.

For what it's worth Authentik has been listing Cloudflare as a customer for a while. Worth a look. There might be something in their blog.
Yes! I used keycloak for multitenant auth and it worked fine - a little dated but functional. Nowadays I'd probably stick to something like Clerk/BetterAuth/Supertokens.

I've seen it used in production by larger orgs. The scale where you plan for around 6 months of migration, customization and integration of your legacy zoo with 7 different user account DBs. On one hand, all of these projects were successful and now run it in production. On the other, they all really needed the 6 months to whip it into shape.
Edit: Meaning I would use it if you need to get up and running quickly, but it's a solid foundation to build on long-term.
