## Choose when

### Choose SeekStorm if…

- Pricing: Free and open-source under the Apache-2.0 license.
- SeekStorm and pgvecto.rs both offer vector search functionalities but SeekStorm highlights sub-millisecond speeds specifically, targeting efficiency.
- Tags unique to SeekStorm: full-text-search, ai-search, enterprise-search, dense-retrieval.
- Also covers Data & Retrieval.
- SeekStorm ships Docker support for self-hosted deployment.
- When your application requires both fast lexical (keyword) search and exact sub-millisecond vector similarity retrieval

### Choose pgvecto.rs if…

- SeekStorm and pgvecto.rs both offer vector search functionalities but SeekStorm highlights sub-millisecond speeds specifically, targeting efficiency.
- Tags unique to pgvecto.rs: postgresql, rust, vector-search.
- - **When high dimensionality support is required**: Supports up to 65535 dimensions which can be crucial if the use case involves very dense or complex feature spaces

## When NOT to use SeekStorm

- In scenarios where Java or Python compatibility is essential and there's reluctance in rewriting application logic to work with Rust components
- If the project strictly requires a cloud-native service rather than an in-process library and multi-tenancy server setup
- When your search requirements are solely lexical or vector-based without needing hybrid functionality

## When NOT to use pgvecto.rs

- - **If you prioritize stability over cutting-edge features**: Developers have pointed to a newer implementation named VectorChord which is said to offer superior stability; consider migrating if long-
