How did you arrive at 1.5%? What data sources are you using?
What are you measuring? Number of companies/organizations that use it? Number of users represented by an account with some Keycloak installation?
There are some ways of using archive.org or commoncrawl data to match on OIDC well-known configuration endpoints that match the Keycloak URI pattern. We did a similar thing ~2 years ago and were able to discover ~70,000 publicly accessible realms for ~16,000 unique Keycloak installations using this method. However, this doesn’t account for those that 1) weren’t crawled, 2) weren’t saved because of a robots.txt rule, or 3) are not publicly accessible.
We didn’t compare this to other IAM systems, but there are Gartner/Forrester reports that indicate the customer size of commercial offerings in the space. Our best guess based on our own research is the Keycloak is the “iceberg” in the market, with a very small public presence, but is actually adopted far beyond that of other commercial IAM systems.
Once upon a time we advocated for anonymous data collection by Keyclok, both to understand usage and automated error reporting, but it was refused.
I also have the feeling that Keyclaok is the market leader, certainly in open source IAM, but I can’t prove it. The active community, many Git stars and also books about Keycloak speak for it.
FYI the link https://6sense.com/tech/identity-and-access-management/keycloak-market-share gives me a 403. Maybe it is because I’m in the EU? If you have access and can post the content, please do.
Iam only able to upload one image so here is some text too:

Hi Maho01,
I wanted to know if you have completed your thesis on this. Even I am doing something similar and cannot find any proper response through the net.
I could really use your help. Please let me know if you have anything on this or you could help me in anyway.
