# GDB-Engines

> Open-source comparison and monthly popularity ranking of 131+ graph databases, query engines, extensions, and embedded libraries. Covers property graph (LPG), RDF, and multi-model engines. Feature scores derived from peer-reviewed academic research; popularity rankings blended monthly across adoption, activity, community and research signals from public sources.

## Comparison

- [Homepage](https://gdb-engines.com/): Interactive comparison of 131+ graph databases with 46 academic feature scores, license, query languages, implementation language, and overall popularity rank.
- [About](https://gdb-engines.com/about): Methodology, data model, contribution guidelines, changelog.
- [JSON API](https://gdb-engines.com/api.json): Full dataset.

## Rankings
