nucliadb-utils
NucliaDB util library
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries permissive Apache-2.0 licensing, and reports no known security vulnerabilities. Install it if you are building applications that depend on NucliaDB or need its utility functions. The main caveat is that the fact sheet does not detail the public API, so verify that the specific utilities you need are actually exported before committing to a dependency.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later (supports 3.10, 3.11, 3.12); does not support earlier versions.
- Low friction installation with a pure-Python wheel.
- Actively maintained with recent releases.

What it is and what it does
nucliadb-utils is a utility library that supports interaction with NucliaDB, an open-source hybrid search database written in Rust and Python. NucliaDB indexes unstructured data using vector embeddings, full-text search, and graph indexes, and is designed for multi-tenant deployments. This package provides helper functions and data structures to work with NucliaDB's APIs and data models.
The package depends on standard Python libraries for async HTTP (aiohttp, httpx), configuration (pydantic, pydantic-settings), authentication (PyNaCl, pyjwt), and observability (prometheus-client, nucliadb-telemetry). It is actively maintained, supports modern Python versions, and carries no known security vulnerabilities.
Use it for
- Building client applications that query NucliaDB for semantic or full-text search over unstructured documents.
- Integrating NucliaDB into data pipelines that require hybrid search across vectors, keywords, and graph relationships.
- Developing multi-tenant applications that leverage NucliaDB's cloud-native architecture for data storage and retrieval.
- Prototyping NLP-driven search features without implementing vector indexing or full-text search from scratch.
