Open-source vector database

As of 30 August 2026, Weaviate is free to use. Weaviate is an open-source vector database that stores both objects and vectors, allowing for combining vector search with structured filtering. Softwr lists it under Machine Learning. Weaviate is launched in 2019, available on Linux, macOS, Windows, Web.

Overview

What Weaviate does

Weaviate is an open-source vector database that stores both objects and vectors, allowing for combining vector search with structured filtering. It supports various ML models for vectorization and provides GraphQL and REST APIs for querying.

What people use it for

  • Running a vector database for semantic and hybrid search
  • Generating and storing embeddings alongside the objects they describe

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Weaviate.

  • The free tier caps at 100,000 objects, 1 GB of memory and a single collection
  • Billing is per million vector dimensions rather than per record, so wider embeddings cost proportionally more for the same object count
  • Premium is a prepaid contract starting at $400 a month rather than pay as you go
  • Storage rates do not fall consistently with tier, and Premium Dedicated is $0.1505 per GiB against $0.12 on the cheaper Flex plan
  • The Query Agent is metered separately, free to 1,000 requests a month and $30 a month plus overage beyond

Softwr does not host reviews and shows no star rating for Weaviate, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
