Weaviate pricing guide details
Pricing Overview
Weaviate uses a freemium pricing model built around an open-source core and managed cloud tiers. The open-source version is free to self-host with no licensing restrictions. For managed cloud, Weaviate offers an always-free managed plan for evaluation, then paid Flex at $45/month minimum and Premium from $400/month, with shared or dedicated Premium deployment. The plan minimum includes the baseline cluster, vector dimensions, and storage; backups are charged separately. Self-hosting on Kubernetes or Docker costs $0 in licensing but requires your own compute budget, from a small VPS to a production Kubernetes cluster. The pricing was restructured in October 2025, replacing older Serverless/Enterprise tiers with the current Flex and Premium model.
Plan Comparison
Weaviate offers five distinct deployment options, from free self-hosted to fully managed enterprise infrastructure.

| Plan | Base Price | Uptime SLA | Deployment | Backup Retention | Support | Query Agent Requests |
|---|---|---|---|---|---|---|
| Open Source (Self-Hosted) | $0 | N/A | Your infrastructure | Self-managed | Community forum | Unlimited |
| Free | $0 (always free) | N/A | Shared cloud | None | Community forum | 1,000/month |
| Flex | $45/month minimum | 99.5% | Shared cloud (GCP) | 7 days | Email (next-business-day) | 30,000/month |
| Premium (Shared) | From $400/month | 99.9% | Shared | 30 days | Phone and Slack | Unlimited |
| Premium (Dedicated) | From $400/month | 99.95% | Dedicated | 45 days | Phone and Slack, 1-hour Severity 1 | Unlimited |
The plan minimum includes the baseline cluster, vector dimensions, and storage; backups are charged separately based on data volume and retention. Vector dimensions start from $0.00465 per million on Flex and $0.003875 per million on Premium, and rates vary by cloud provider and region. Storage starts from $0.12 per GiB on Flex and $0.10 per GiB on Premium. Backup storage starts from $0.03036 per GiB on Flex and $0.021 per GiB on Premium. The Flex plan rate from $0.00465 per million dimensions is higher than the Premium rate, which rewards commitment with lower per-unit costs.
For context, a RAG application with 500,000 documents using 1536-dimensional OpenAI embeddings and a replication factor of 2 would consume roughly 1.54 billion vector dimensions—about $7 per month in dimension costs alone at the starting Flex rate of $0.00465 per million, well under the $45 Flex minimum.
Hidden Costs and Considerations
The managed Free plan is always free, requires no credit card, and can be upgraded to a paid plan at any time. Flex at $45/month is a minimum, not a flat rate—heavy usage can push costs significantly higher. Premium requires a prepaid contract, reducing month-to-month flexibility. Self-hosted deployments carry compute, storage, and engineering maintenance costs that scale with your cluster size. Premium's BYOC (Bring Your Own Cloud) option adds complexity to your cloud bill even though it solves data residency requirements.
Cost Estimates by Team Size
These estimates are based on actual pricing dimensions from Weaviate's current billing model.
Scroll sideways to see all columns. With a keyboard, focus this table and use the arrow keys.
| Team Size | Recommended Plan | Estimated Monthly Cost | Use Case |
|---|---|---|---|
| Solo developer | Self-Hosted | $0 software; a VPS if not local | Local Docker or small VPS for prototyping |
| Small team (2–5) | Flex | From $45/month, plus usage | Production RAG or search with under 1M vectors |
| Growth team (5–15) | Premium | Quote only | Higher availability needs, dedicated deployment option |
| Enterprise (15+) | Premium | From $400/month (prepaid) | Dedicated infrastructure, HIPAA compliance, multi-region |
Below that threshold, self-hosting is cheaper. Above it, Cloud Flex becomes competitive when you factor in engineering time saved on maintenance, upgrades, and monitoring.
How Weaviate Pricing Compares
We compared Weaviate against three prominent vector database alternatives in the managed cloud space.
Scroll sideways to see all columns. With a keyboard, focus this table and use the arrow keys.
| Tool | Pricing Model | Starting Price | Enterprise Tier | Best For |
|---|---|---|---|---|
| Weaviate | Freemium + usage-based | $45/month (Flex) | $400/month (Premium) | Teams wanting open-source flexibility with managed cloud option |
| Pinecone | Usage-based | $0 (free tier, then $50/month) | $500/month | Fully managed vector search with zero ops overhead |
| ChromaDB | Usage-based | $0 (free tier available) | $250/month | Lightweight embedding workflows and rapid prototyping |
| Qdrant | Freemium | $0 (free tier) | Custom pricing | Open-source teams needing fine-grained filtering |
Weaviate's Flex plan at $45/month sits slightly below Pinecone Standard at $50/month, making them closely competitive for small production workloads. Weaviate's key advantage is the open-source self-hosted option—neither Pinecone nor Chroma Cloud offer a comparable free self-hosted path with the same feature completeness. For teams with DevOps capacity, self-hosting Weaviate on a $20/month VPS undercuts every managed competitor.
