SpacetimeDB is a relational database that embeds application logic—written as stored‑procedure “modules” in languages like Rust—directly inside the database, letting clients execute that logic without a separate server tier. It’s aimed at developers of real‑time applications such as games, chat, and collaborative tools who want a single‑binary, low‑latency backend that handles both data storage and business rules.
