Weaviate pricing: the quick answer

Quick answerLast verified: July 8, 2026High

Weaviate is free to start as of July 8, 2026. Self-host the open-source build under BSD-3 at no cost, or use the managed Sandbox free for 14 days. Paid cloud begins at Flex, a $45 a month minimum billed pay-as-you-go: $0.01668 per million vector dimensions plus $0.255 per GiB of storage. Plus starts at $280 a month on an annual commitment, and Premium from $400 with a cheaper $0.00975 dimension rate. Weaviate meters by total dimensions, objects times embedding size, not tokens. Managed embeddings and the Query Agent are separate charges.

What Weaviate really costs

What sits on top of the plan fee

Weaviate bills by total vector dimensions, so the base plan is a minimum, not a cap. Storage, backups and the embedding and agent add-ons all stack on top of that per-dimension rate.

Per-dimension usage and plan minimums

Flex charges $0.01668 per million vector dimensions plus $0.255 per GiB stored, against a $45 monthly minimum that you pay even on light usage. Premium drops the dimension rate to $0.00975, a 41.5% cut, but starts at a $400 minimum. Since dimensions are objects multiplied by embedding size, a 768-dimension model over a few million objects racks up billions of dimensions, so model that count before picking a tier.

$0.01668/M dimensions (Flex), $0.00975 (Premium)

Backup storage and retention

Backups are charged on top of the base plan by data volume and retention window, at $0.0264 per GiB on Flex with 7-day retention. It is a small rate, but longer retention on a large index turns it into a recurring line the headline per-dimension price does not include.

Embeddings and Query Agent add-ons

Managed embeddings bill separately from $0.025 per million tokens for Snowflake Arctic-Embed up to $0.065 for ModernBERT, and the Query Agent is $30 per org a month for 4,000 requests before pay-as-you-go above that. Every plan includes 1,000 agent requests free, so these only bite once you lean on Weaviate's own embedding and agent layer instead of bringing your own.

$45/mo55% below median

Category median: $99/moBased on 8 products in this category

Weaviate gives you two free paths, the BSD-3 open-source build you self-host and a 14-day managed Sandbox, then meters paid cloud by total vector dimensions. Flex is a $45/mo minimum at $0.01668 per million dimensions plus $0.255/GiB storage. Plus starts at $280/mo on an annual commitment, and Premium from $400/mo drops the dimension rate to $0.00975, a 41.5% cut. The dimension-based model is unusual and rewards compression, but it also means the base plan is a floor you pay regardless of a quiet month.

Hidden Costs

Every paid tier carries a monthly minimum you pay even on low usage: $45 on Flex, $280 on Plus, $400 on Premium.
Backups bill on top by volume and retention, at $0.0264/GiB on Flex.
Managed embeddings run $0.025 to $0.065 per million tokens and the Query Agent is $30/org/mo above the free 1,000 requests, so the add-ons stack on the database charge.

Red Flags

Users warn that cloud cost can climb unpredictably as dimensions and query volume grow, and the step from the flat Flex minimum into consumption-based enterprise pricing is not transparent, which makes budgeting hard for a scaling startup.

Green Wins

Open source plus a managed cloud gives you real deployment flexibility.
Built-in vectorizers cut pipeline complexity.
Cross-references and hybrid BM25 plus vector search in one engine.

"Users consistently praise the ease of use and excellent customer support provided by Weaviate"
G2

Verdict

Startups prototyping RAG should begin on the free Sandbox or the $45/mo Flex plan and watch the dimension count as data grows. Teams with strict security needs should look at BYOC to keep data in their own cloud. If Weaviate's dimension-based scaling looks too unpredictable for your workload, compare a flat-rate managed option like Pinecone.
