GraphLite
It’s an embeddable graph database, written in Rust, single binary, SQLite-shaped developer experience. No server, no daemon: open a path, run queries.
The interesting part isn’t the embedding. It’s that GraphLite fully implements ISO GQL end-to-end, built on the OpenGQL reference grammar. Not Cypher, not Gremlin but the standard itself. It joins Google Spanner Graph and Ultipa as one of the few engines to fully commit. There are only three as far as I know.
The embedded-graph category is becoming serious again. Post-Kuzu reality. GQL adoption is the slow-moving story that will eventually collapse dialect fragmentation the way SQL did.
Well, like SQL, we will see the standard GQL as a common denominator, with lots of additional vendor-specific extensions.
