Heya, glad you are taking a look around. There's lots of players offering solutions.
Here are some of the companies I see mentioned, along with my back of the envelope categorization of them; there is overlap and the categories are fuzzy, but hopefully that helps you pick and choose what to research. More info is only a google away.
OAuth/standards based solutions
* fusionauth
* auth0
* identity server/duende
Open source solutions
* ory
* keycloak
* zitadel
JavaScript focused solutions
* stytch
* propelauth
* clerk
* frontegg
* supertokens
Workforce oriented options:
* okta
* ping
* onelogin
* wso2
Hope this helps. Reach out if you'd like to chat more about FusionAuth. I'm not a co-founder (waves to Julianna) but I'm a long time employee.
Also, here are some community stories, based on interviews with folks who've used FusionAuth: https://fusionauth.io/blog/archive/category/community-story/
If you're going to write about the competition, at least be fair and accurate.
But Okta itself has focused on the workforce (IAM) product, rather than one focused on many users, which is why they bought Auth0, which they do own, as you correctly stated. If you go to okta.com, they have 'customer identity' and workforce identity' as the first two options of their menu. But my understanding is that 'customer identity' is really the Auth0 platform.
I did say:
> there is overlap and the categories are fuzzy
I didn't mean to imply that Okta didn't support standards. However, standards implementation isn't (in my mind) their defining characteristic, IAM/workforce management is. Just like some of the JS focused providers support OAuth, but the defining characteristic is their focus on JS/front end frameworks.
I'll end by saying that I haven't done a deep dive into all of these options, these are just some of the companies in the space. Caveat emptor, do your own diligence.
(From your profile link, I see that you are an Okta employee. I'd love to have your insight into how you'd group the competitors to help OP do their research to find the right solution.)
Okta had a customer identity solution even before they bought Auth0.
I know almost nothing about Okta's competitors, which is why I said nothing.
> Okta had a customer identity solution even before they bought Auth0.
Correct. Stormpath was acquired in the mid 2010s, if I recall correctly. I believe that is being sunsetted for Auth0 currently (based on my research).
I’m the founder of FusionAuth and have deep knowledge on OAuth and SAML. The groupings Dan used seem like a decent assessment with some caveats.
> caveats
And I'm pointing those out.
