Added 1 June 2026
Overview
AquilaDB is an open source neural search engine that indexes latent vectors alongside JSON metadata. It performs efficient k-nearest neighbor search on these vectors. The tool is designed to be easy to use and is maintained by the community.
Best for
Best for
Developers needing quick vector search with JSON metadata for small to medium datasets.
Use cases
- Perform vector similarity search on embedding outputs from machine learning models.
- Filter and retrieve items by combining vector proximity with JSON metadata constraints.
- Build a lightweight backend for neural search applications where rapid prototyping is needed.

Use cases
- Perform vector similarity search on embedding outputs from machine learning models.
- Filter and retrieve items by combining vector proximity with JSON metadata constraints.
- Build a lightweight backend for neural search applications where rapid prototyping is needed.
Pros
- Simple setup and usage for basic vector search tasks.
- Supports combined search over vectors and JSON metadata.
- Open source with no licensing costs.
Cons
- Low community engagement with only 380 stars, suggesting limited adoption and support.
- Written primarily in HTML, which may indicate a thin client rather than a robust server-side engine.
- Likely lacks advanced features found in more mature vector databases like scalability or distributed search.
