Why I Recommend This
As someone who frequently works with Keycloak, the Theme Builder has completely transformed my workflow.
Creating custom themes used to mean manually tweaking FTL templates and CSS - a tedious process that often resulted in compatibility issues. Now, with this visual builder, I can create beautiful, brand-compliant themes in minutes without writing a single line of code.
The live HTML preview feature is particularly impressive - I can see exactly how my theme will look across all 9 authentication pages, including login, registration, and password recovery, in real-time.
This eliminates the guesswork and the constant cycle of redeploying and refreshing to check minor CSS adjustments.
Beyond just the speed, the ability to export a production-ready .ftl file directly from the interface has bridged the gap between design and deployment.
It ensures that the final product is not only aesthetically pleasing but also technically sound and compatible with various Keycloak versions.
It has truly turned a once-dreaded task into one of the most efficient parts of my development pipeline.
