At Keycloak DevDay 2026, we shared our work on replacing Keycloak's distributed Infinispan caches with Redis/Valkey.
For the full technical deep dive, we will release slides when the talk is published on Youtube.
This post focuses on the core technical content from the presentation and summarizes what we built, what we learned, and what comes next.
Developing custom additions to the Keycloak Admin UI can be fiddly and slow. At Phase Two we maintain several popular community extensions that must track frequent Keycloak releases. Below is the approach we use to develop and verify Admin UI changes quickly against a running Keycloak image that includes our extensions.
We’re excited to announce the release of Self-Service Resource Management in the Phase Two Dash. This new capability empowers customers running dedicated Keycloak clusters to directly upload and manage their own resources—such as custom themes and extensions—without waiting for Phase Two intervention.
We recently gave a talk at the Keyconf24 conference in Vienna on how to extend Keycloak using its extensible SPI structure. In addition to showing what is possible and how to get started in building extensions, we also use our Events and Webhooks extension as a real-world example. The hosts of the conference have posted the video of the talk on Youtube.
