Slater: A Low-Memory Graph Database for Massive Read-Heavy Graphs

Slater – Low-memory graphdb designed for read-heavy graphs

I built Slater to solve the biggest complaint about graph databases: they don't scale past what fits in RAM. Unlike competitors that require massive memory for large graphs, Slater serves hundreds of millions of nodes from just a few hundred megabytes of RAM. It uses a disk-native approach with Bolt protocol support, allowing you to use standard neo4j drivers while keeping memory costs predictable regardless of graph size.
