[chroma](https://www.trychroma.com/) reports 29k GitHub stars, 2.4k forks, and 746 open issues, last pushed Jul 27, 2026. [crate](https://cratedb.com/database) has 4.4k stars, 608 forks, and 331 open issues, last pushed Aug 21, 2026. Figures are from public GitHub metadata via [chroma's repository](https://github.com/chroma-core/chroma) and [crate's repository](https://github.com/crate/crate). | | [chroma](/tools/chroma-core-chroma.md) | [crate](/tools/crate-crate.md) | | --- | --- | --- | | Tagline | Search infrastructure for AI | Distributed and Scalable SQL Database for Near Real-Time Data Analysis | | Stars | 28,898 | 4,424 | | Forks | 2,409 | 608 | | Open issues | 746 | 331 | | Language | Rust | Java | | Adopt for | Chroma is an open-source data infrastructure for AI designed to support vector, hybrid, and full-text search capabilities with high performance. | CrateDB is distinguished by its capability to manage massive data volumes in near real-time with PostgreSQL compatibility and Lucene-based indexing. | | Persona | - | - | | Runtime | - | - | | License | Chroma is released under the Apache 2.0 license. | Apache-2.0 | | Categories | Data & Retrieval, Vector Databases | Data & Retrieval, Vector Databases | ## Trust and health _Sourced signals - not a safety guarantee.
