Redis City - Interactive 3D model of Redis internals

Show HN: Redis City – Explore how Redis works in an interactive 3D model

Redis City turns a single Redis instance into an explorable 3D city, revealing how data structures, memory, and persistence work under the hood. Built with Redis 8.10.1, it visualizes the command path, string encoding, hash internals, snapshotting with COW, key expiration, and maxmemory pressure. You can run experiments, step through time, and inspect every layer from RESP parser to kernel page cache. It's a hands-on educational tool for developers who want to truly understand Redis beyond the CLI.
