Torollo

Interactive playground for learning system design and networking, self-hosted

PlatformWebfreeglobal

An open-source, self-hosted visual playground that runs each diagram node as a real Docker container and provides guided roadmaps which check progress against the live system state. It helps developers learning system design and networking get hands-on practice and immediate infrastructure feedback — validating network rules and services in a working environment instead of relying on unverified diagrams.
