Free tier + pay-as-you-go + annual/prepaid contract tiers + usage-based metered dimensions
Public materials describe Flex as monthly pay-as-you-go with no commitment, while Plus and Premium are annual or prepaid contract offerings. The official pricing page also states that paid plans are not all identical: Plus emphasizes predictable spend, Premium says monthly minimums vary by configuration, and the blog notes that existing annual and multi-year contracts adopt the new model at renewal. The support page adds that sandboxes are not eligible for paid support, and the pricing page indicates a free tier with no credit card required. A forum post from March 2025 documents an older public estimate of $25/month for a non-HA serverless cluster, which differs from the current public pricing page.
Free sandbox clusters are for experimentation and prototyping. Paid support is not available on sandboxes, and the tier is capped at 100,000 objects, 1 collection, and limited AI-service request quotas.
Unlimited objects and 1,000 collections are shown on the pricing comparison table; backup retention is 7 days. It is positioned as the zero-commitment entry point for prototypes, pilots, and small use cases.

The public pricing page lists an Always free tier with $0/month and no credit card required. That tier is positioned as a fully managed AI database experience for getting started quickly. It also comes with specific limits such as object, memory, disk, and request quotas.
Flex starts at $45/month on the official pricing page. It is billed monthly on a pay-as-you-go basis with no commitment. The plan includes a shared cloud cluster, HA, RBAC, and usage-based AI services, so the final bill can increase with consumption.
Yes, the official pricing page lists starting prices for both tiers: Plus starts at $280/month and Premium starts at $400/month. However, Premium also notes that monthly minimums vary by configuration, so the displayed entry price is not necessarily the final spend. Plus and Premium are framed as contract-style offerings with annual or prepaid commitments.
A Weaviate community forum post from March 2025 says the older public page showed pricing starting at $25/month for a non-HA serverless cluster, while a support reply explains that the $75/month estimate was for a High Availability cluster. The current official pricing page now shows Flex starting at $45/month, and the blog says the new pricing took effect on October 27, 2025 for new customers. In other words, the $25/month reference appears to be an older pricing state rather than the current public entry price.
