One options set. Two factories. Apps that can sync.
SW-Builder is a pair of software factories.
You do not design the car from scratch. You pick a short list of options. The factory stamps a working product from a shared chassis. Droid Builder stamps native Android apps. WildFly Builder stamps Java EE / WildFly apps. Both read the same kind of options file. Both overlay a template, pull a snippet library, and run an app-specific extender.
The point of this site is to show the factories, not just the apps they emit. The catalog is the evidence: Booklet, Social, and Security exist on both chassis. Setup notes and source sit next to the running idea so the process is copyable.
This is not a hosted low-code canvas and not a one-shot LLM scaffold. After the stamp, the result is a normal Android or WildFly project that you own. Build and deploy stay in the generated app repo.
SW-Builder is built and operated by Ronald Kanengieter. The site is self-hosted on WildFly.
