Understand the project
Practical overview
When it fits
Use Zvec when search and retrieval need to live inside the application process, with local storage and without a separately configured database server.
Who it is for
- Developers building desktop, server, command-line, notebook or edge applications
- Teams implementing semantic search or retrieval-augmented generation
- Developers adding local memory storage to LLM-based software
- Developers needing hybrid vector and full-text retrieval
Documented uses
- Store and retrieve vectorized application data locally
- Find semantically similar documents or records
- Combine vector search with full-text queries and structured filters
- Provide a local retrieval layer for RAG systems
- Support an LLM application memory store
Before you choose
Requirements & limits
The project is described as open-source and is licensed under Apache-2.0. Documented installation routes include Python, Node.js, Go, Rust and Dart/Flutter. Supported platforms listed by the repository are Linux, macOS and Windows.
- In-process architecture avoids a separate database server and configuration layer.
- The search model includes dense and sparse vectors, full-text search and structured filters.
- Write-ahead logging is documented for persistent storage.
- Multiple processes can read the same collection, but writes are single-process exclusive.
- Python users need 64-bit Python 3.10–3.14.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
