PGSimCity: An Explorable 3D Model Revealing How PostgreSQL Actually Works

PGSimCity – an explorable 3D model that shows how Postgres works

I created PGSimCity to turn complex PostgreSQL internals into an explorable 3D city where engineers can visualize database operations. This independent educational tool lets you walk through districts representing the buffer pool, WAL, and storage to understand latency spikes and transaction bloat. It serves as a precise model, not an emulator, helping developers grasp why specific settings like synchronous_commit impact performance without needing to install anything.
