Weaviate Pricing: Self-Hosted, Cloud Flex, Plus & Premium (April 2026)

Weaviate updated its cloud pricing in late 2025, replacing the old Serverless/Enterprise tiers with Flex, Plus, and Premium plans. Self-hosted Weaviate is still free and open source. The cloud plans start at $45/month for Flex (pay-as-you-go) and go up to Premium for enterprise deployments. There's also a free 14-day sandbox for testing. This page covers every option and helps you choose between self-hosted and managed cloud.

Self-Hosted vs Cloud: The Real Tradeoff

Self-hosted Weaviate is free, but it's not zero-effort. You need to provision infrastructure, configure backups, handle upgrades, and monitor performance. For a small RAG application, a $20/month VPS running Docker is all you need. For a large production deployment, you're looking at Kubernetes orchestration and potentially $200-1,000/month in compute costs.

Cloud Flex eliminates operational overhead. Weaviate handles scaling, backups, upgrades, and monitoring. The $45/month minimum is the price of that convenience. For teams without dedicated DevOps, cloud is usually worth the premium.

The breakpoint: if your self-hosted infrastructure costs exceed $100-200/month and you're spending significant engineering time on maintenance, Cloud Flex is comparable in total cost and saves engineering hours.

Hidden Costs & Gotchas

⚠ The 14-day free sandbox expires automatically. You can't extend it. If you need more evaluation time, spin up a new sandbox or self-host locally.
⚠ Flex at $45/month is a minimum, not a flat rate. Actual costs depend on storage volume, vector dimensions, and query volume. Heavy usage can exceed the minimum.
⚠ Plus at $280/month requires annual commitment options. Monthly flexibility costs more. If your usage is unpredictable, Flex's pay-as-you-go model is safer.
⚠ Self-hosted is free but not zero-cost. You pay for compute, storage, and the engineering time to manage Weaviate yourself. For small deployments, self-hosted on a $20/month VPS is cheaper than any cloud plan.
⚠ BYOC (Bring Your Own Cloud) on Premium lets Weaviate manage the database inside your AWS/GCP/Azure account. This solves data residency requirements but adds complexity to your cloud bill.

Which Plan Do You Need?

Individual developer or prototype

Self-hosted (free). Run Weaviate in Docker locally or on a small VPS. The 14-day sandbox is good for quick tests but not for sustained development.

Startup or small production app

Cloud Flex at $45/month. Pay-as-you-go pricing with no annual commitment. Good enough for most production RAG and search workloads.

Enterprise with compliance needs

Cloud Plus ($280/month) or Premium (custom). Plus gets you dedicated infrastructure and 99.9% SLA. Premium adds BYOC for data residency requirements.

The Bottom Line

Self-hosted Weaviate is the best deal in vector databases, full-featured and free. Cloud Flex at $45/month is competitive with Pinecone Standard ($50/month) for teams that want managed infrastructure. The Plus and Premium tiers make sense for enterprises that need SLAs and compliance. If you have a DevOps team, self-hosted saves significant money at any scale.

Frequently Asked Questions

Is Weaviate free?

Weaviate is open source and free to self-host with no restrictions. The managed cloud service has a free sandbox tier (14-day expiration) and paid serverless plans starting with usage-based pricing. Self-hosting is free if you have your own infrastructure.

How much does Weaviate Cloud cost?

Serverless Cloud charges per dimension-hour for storage and per dimensions queried. A typical small workload (500K vectors, 1536 dimensions, moderate query volume) costs $30-80/month. Costs increase with vector count, dimensions, and query frequency.

Should I self-host Weaviate or use the cloud?

Self-host if you have DevOps capability and want full control over costs and performance. Use the cloud if you want zero infrastructure management and your workload is small-to-medium. The breakeven point is roughly 5M vectors, where self-hosting becomes cheaper.

How does Weaviate compare to Pinecone?

Weaviate offers self-hosting (Pinecone doesn't), hybrid search (vector + keyword), and more flexible data modeling. Pinecone has simpler serverless pricing and less operational overhead. Weaviate is cheaper at scale due to the self-host option. Pinecone is easier to start with.
