I used Keycloak about 4 or 5 years ago in a former job. It did work very well. Note however, that we did not need to customize anything nor did we have to deal with scaling (in house web-app where it was rare to have more than 100 people using on it at any given day).
Right now, I'm looking into https://supertokens.com/
I have not used it in any capacity but it does seem much more approachable -at least to me- and allows for much flexibility (code wise on your own Backend).
I would be interested in hearing if anyone here has any feedback.
I'm of the project creators. Happy to discuss your specific use case and evaluate different providers.
Some recent feeedback:
"Hi yes, we are testing SuperTokens right now, and we are loving it
Thanks for the great tool btw. it is really comfortable to integrate it into the project.
at first we decided to use Keycloak, spent a week to customize it for our needs. It was soooo painful :sweat_smile: then we started looking for alternatives"
"Been using it a bit for a pet project and I am quite impressed of how many integrations and documentation I find on its page. Also, really easy to use!"
Just in case you are wondering where I found out about SuperTokens, it was on HackerNews"
