Show HN: DummyIDP – Test SAML SSO and SCIM Directory Sync

We heard from people (https://news.ycombinator.com/item?id=41674109#41675409 https://news.ycombinator.com/item?id=41674109#41675409) a while back that there's demand for a lightweight SAML testing tool. So we made one! DummyIDP sends real SAML/SCIM messages to your app – just like Okta or Entra would. But it's radically simple. All of the settings are on the same page. You don't even need to create an account. It's just ready to go. You can test IDP- initiated SAML login. You can test SP- initiated SAML logins. You can provision or deprovision users or edit their permissions. You can test just about everything you could reasonably expect your enterprise customers to do. Here's a demo: https://www.youtube.com/watch?v=K2EMzbJhVag https://www.youtube.com/watch?v=K2EMzbJhVag It's a free and open source tool.
