What's included in the free plan vs paid?

pgvector is entirely free and open-source. The "Open Source" plan *is* pgvector itself, a PostgreSQL extension released under the MIT license. It provides full vector similarity search capabilities directly within your PostgreSQL database without any cost or feature limitations. There are no separate paid plans offered by pgvector.

When does a team or user need to upgrade to a higher plan?

As pgvector is a free, open-source extension, there are no higher plans to upgrade to directly from pgvector. Users typically consider "upgrading" their PostgreSQL hosting solution for managed services, enhanced support, or enterprise features from a cloud provider. pgvector itself remains free regardless of your PostgreSQL deployment choice.

Is annual billing available, and is the discount worth it compared to monthly?

pgvector does not offer any billing options, annual or monthly, as it is a completely free and open-source PostgreSQL extension. There are no subscription fees or costs associated with using pgvector itself, so the concept of billing discounts does not apply.

How does per-seat pricing scale for growing teams?

pgvector does not utilize a per-seat pricing model. As a free and open-source PostgreSQL extension, its usage scales with your PostgreSQL database, not with the number of team members. You can deploy pgvector across any number of instances and users without incurring additional costs from pgvector itself.

Does pgvector offer discounts for startups, nonprofits, or students?

Since pgvector is a free and open-source PostgreSQL extension available under the MIT license, it is already accessible to everyone at no cost. Therefore, specific discounts for startups, nonprofits, or students are not applicable, as the product itself is entirely free for all users.

What are the hidden costs of pgvector beyond the subscription price?

Beyond the pgvector subscription, organizations typically budget for implementation and data migration, user training and onboarding, premium support tier upgrades, required add-on features, third-party integrations, and annual true-up costs from seat overages. These costs can add 20-80% to the base subscription price depending on team size and deployment complexity.

Does pgvector charge for implementation or setup?

pgvector may charge for professional services, data migration, and initial configuration, particularly for enterprise deployments. These costs are typically not listed on the public pricing page and are negotiated separately. Request a total cost of ownership estimate before signing.

Is pgvector pricing stable or does it change frequently?

pgvector pricing has been stable over the last 90 days based on our monitoring. We verify pricing on a rolling 30-day cadence and log all changes in our public changelog.
