Pricing
FreemiumPinecone offers four tiers. Starter is free, for trying out and small applications, including Database On-Demand, Inference, and Assistant access, up to 2GB storage, 2M write units/month, and 1M read units/month, limited to AWS us-east-1. Builder is $20/month flat for solo developers and small teams, adding increased usage limits, choice of cloud and region, multiple projects and users, and Prometheus/Datadog monitoring. Standard has a $50/month usage minimum (pay-as-you-go beyond that, with a 3-week trial including $300 in credits), adding Dedicated Read Nodes, import from object storage, backup and restore, RBAC, and SSO (SAML 2.0), positioned for production applications at any scale. Enterprise has a $500/month usage minimum, adding a 99.95% uptime SLA, Bring Your Own Cloud (BYOC), private endpoints, Customer Managed Encryption Keys, audit logs, service accounts, SAML roles, SCIM, and HIPAA compliance, with Pro support included. Committed Use Contracts offer larger discounts for higher-volume customers. Pinecone is also available on AWS Marketplace, Google Cloud Marketplace, and Microsoft Marketplace.
FreemiumWeaviate Cloud offers a permanently free tier: $0/month, 1 cluster per user, 100,000 objects, 1 GB memory, 10 GB disk, 1 collection with up to 3 tenants, 2,000 embeddings requests/day, and 1,000 Query Agent requests/month, no credit card required. Flex starts at $45/month on a pay-as-you-go basis with no commitment, unlimited objects, up to 1,000 collections, full core database toolkit with replication, RBAC, 99.5% uptime, and next-business-day Severity 1 support; billed on vector dimensions (from $0.00465/1M), storage (from $0.12/GiB), and backups (from $0.0264/GiB) on top of the base minimum. Premium starts at $400/month on a prepaid contract, offering choice of shared or dedicated deployment, up to 99.95% uptime, SSO/SAML, global coverage on AWS/GCP/Azure, and enterprise support as fast as 1-hour Severity 1 response with a dedicated Technical Account Team; dedicated deployment adds HIPAA compliance, AWS PrivateLink, and customer-managed encryption keys. Weaviate Embeddings is billed separately per model, from $0.025 to $0.065 per 1M tokens. Query Agent is free to try (1,000 requests/month) or $30/month per organization for 4,000 included requests plus usage-based overage.

Pinecone

Pinecone Pros & Cons

Pros

  • Fully managed with automatic indexing and no manual tuning required, even at billion-vector scale
  • Consistent query performance that doesn't degrade as data volume grows
  • Nexus offers a genuinely different, more efficient approach to agent knowledge retrieval than repeated agentic RAG calls
  • Native plugin support for Claude Code, Cursor, and other modern AI coding tools
  • Enterprise-grade security posture (SOC 2, HIPAA, GDPR, ISO 27001) with BYOC for maximum data control

Cons

  • Regional availability is limited on lower tiers; the free Starter plan only runs in AWS us-east-1
  • Standard and Enterprise plans carry monthly usage minimums ($50 and $500 respectively) rather than pure pay-as-you-go from zero
  • Enterprise-grade features like BYOC, CMEK, audit logs, and SCIM are gated to the top Enterprise tier
  • As a specialized vector database, it requires pairing with a separate LLM and embedding pipeline unless using Pinecone's own Inference and Assistant add-ons
  • Smaller company scale (roughly 128 employees, ~$27M ARR) relative to database incumbents now offering competing vector search features
Weaviate

Weaviate Pros & Cons

Pros

  • Genuinely free tier with no credit card required, plus fully open-source self-hosting as an alternative
  • Unifies vector search, RAG, embeddings, and personalization (Engram) in one platform instead of stitching together separate tools
  • Query Agent removes the need to hand-write vector or hybrid search syntax for common requests
  • Efficient multi-tenancy lets a single cluster support tens of thousands of isolated tenants, ideal for SaaS builders
  • Strong enterprise trust signals: SOC 2 Type II audited, HIPAA compliant on Enterprise Cloud, 20M+ open-source downloads

Cons

  • Free tier is capped at 100,000 objects and a single collection, pushing real projects to paid plans quickly
  • Premium tier requires a prepaid contract starting at $400/month, a jump from the pay-as-you-go Flex tier
  • Pricing based on vector dimensions and storage can be harder to estimate upfront than flat per-seat pricing
  • SSO/SAML, HIPAA compliance, and PrivateLink are reserved for Premium and Dedicated tiers, unavailable on Free or Flex
