Weaviate
Weaviate is an open‑source vector database and managed cloud service combining vector search, embeddings, retrieval‑augmented generation (retrieval-augmented generation), and a memory service. It offers SDKs, REST/GraphQL APIs, an Always free cloud tier, and paid Flex and Premium plans with usage billing for embeddings and query services.
Weaviate Cloud includes an Always free tier and two paid tiers: Flex (pay-as-you-go, starts at $45/mo) and Premium (prepaid, starts at $400/mo). Embeddings and Query Agent are billed by usage; specific per-token and request rates are listed for cloud-hosted services.Is Weaviate right for you?
Good for
- Teams building vector search, retrieval-augmented generation, or memory-enabled apps that want an integrated platform with built‑in embeddings, a Query Agent, SDKs, and a free cloud tier for experiments.
- Single platform combining vector search, retrieval-augmented generation, and memory reduces need for separate embedding pipelines or external memory layers.
- Managed cloud offering includes an Always free tier that provides a working cluster and free embedding and Query Agent allowances for experiments.
Keep in mind
- Bring-your-own identity provider (IdP) support is not available now and is listed as coming soon for cloud plans.
- Free tier backup retention is not provided; higher tiers document 7–45 day backup retention depending on plan.
- If you assume IdP/SSO or extended backup retention on lower cloud tiers, verify which cloud tier includes your required identity provider and backup retention before provisioning.
Pricing and plan limits
Pricing pages list an Always free tier and concrete starting prices for Flex and Premium; detailed per-feature usage rates for embeddings and query agent are on the same page. The linked official pages do not list self-hosting infrastructure or third-party hosting costs.
