**Typed relationship:** PageIndex _(alternative)_ weaviate

Pageindex offers an alternative solution focusing on vectorless operations, contrasting with Weaviate's emphasis on vector-based semantic search using a vector database.

## Decision facts: PageIndex

- **Requirements:** PageIndex operates independently of vector databases, and it does not require Docker. However, specific resource requirements depend on the scale of documents.
- **Adopt for:** PageIndex is a reasoning-based RAG system suitable for applications requiring context-aware retrieval and avoiding vector databases or chunking, specifically designed to handle professional long-form documents.

## Decision facts: weaviate

- **Pricing:** freemium - Open-source version is available for free; Weaviate Cloud offers premium paid plans with enterprise-level features.
- **Requirements:** Min 2 GB RAM; Requires Docker; Requires a container environment like Docker or Kubernetes for deployment.; Supports importing pre-generated vector embeddings along with objects.
- **Adopt for:** Weaviate is an open-source vector database with robust cloud-native architecture, supporting both automated and custom vector embedding. It integrates multiple machine learning models like OpenAI, Cohere, and HuggingFace

## Choose when

### Choose PageIndex if…

- PageIndex is primarily Python; weaviate is Go.
- License: PageIndex is MIT, weaviate is BSD-3-Clause.
- Requirements: PageIndex operates independently of vector databases, and it does not require Docker. However, specific resource requirements depend on the scale of documents..
- Pageindex offers an alternative solution focusing on vectorless operations, contrasting with Weaviate's emphasis on vector-based semantic search using a vector database.
- Tags unique to PageIndex: agents, llm, reasoning, rag.
- - When handling long professional documents that require deep contextual understanding and multi-step reasoning where traditional similarity searches fall short.

### Choose weaviate if…

- weaviate is primarily Go; PageIndex is Python.
- License: weaviate is BSD-3-Clause, PageIndex is MIT.
- Pricing: Open-source version is available for free; Weaviate Cloud offers premium paid plans with enterprise-level features..
- Requirements: Min 2 GB RAM; Requires Docker; Requires a container environment like Docker or Kubernetes for deployment.; Supports importing pre-generated vector embeddings along with objects..
- Pageindex offers an alternative solution focusing on vectorless operations, contrasting with Weaviate's emphasis on vector-based semantic search using a vector database.
- Tags unique to weaviate: grpc, mlops, approximate-nearest-neighbor-search, nearest-neighbor-search.
- Also covers Vector Databases.
- weaviate ships Docker support for self-hosted deployment.
- When you require a scalable solution for semantic search that can integrate both object data and vectors efficiently.

## When NOT to use PageIndex

- - If your application relies on quick, chunk-based indexing as PageIndex constructs a hierarchical tree index which could be slower for small documents or real-time applications.
- - In scenarios where you already have an established and optimized vector database infrastructure that performs well for your retrieval needs.

## When NOT to use weaviate

- In contexts where an open-source solution is not preferred or compliance requires proprietary software.
- For projects that do not require the combination of vector similarity search with structured filtering and might benefit from a more specialized database solution.
- When the desired deployment environment does not align with Docker, Kubernetes, or major cloud platforms supported by Weaviate.
