Estuary Flow pricing guide details
Pricing Overview
Estuary publishes three tiers: Developer, Cloud, and Enterprise. Developer is free for up to 10 GB of data per month and two connector instances, with no credit card required. It includes real-time or batch pipelines from 200+ connectors, exactly-once delivery, automatic schema evolution, and in-flight transformations.
Cloud uses pay-as-you-go pricing. The published rate is $0.50 per GB plus $100 per connector instance per month; each connector instance after the sixth costs $50 per month. Data is counted when captured from a source and when delivered to a destination, including data produced by transformations. Each active source or destination is one connector instance and is prorated by the hour. Cloud is monthly, can be stopped at any time, and begins with a 30-day free trial when usage goes beyond the Developer level.
Enterprise is a custom annual-contract offering with discounts. It includes Cloud capabilities plus private and Bring Your Own Cloud (BYOC) deployment, SSO, a SOC 2 report, HIPAA BAA, dedicated support, custom SLAs, and migration help. Private and BYOC deployments are available on annual or multi-year Enterprise contracts; a buyer should confirm data volume, connector count, deployment model, contract length, and support needs for an Enterprise quote.

Cloud charges $100 per month for each connector instance through the sixth instance, then $50 per month for each instance after the sixth. A connector instance is an active source or destination and is prorated hourly. Cloud has a 30-day free trial after usage exceeds the Developer level.
Enterprise uses an annual contract with discounts. Private deployment can run in an AWS, GCP, or Azure region, while BYOC runs in the buyer's AWS, GCP, or Azure account. Those deployment options are available on annual or multi-year Enterprise contracts, so buyers should confirm the required deployment model, volume, connector count, term, and support scope.
Hidden Costs and Considerations
Cloud billing has two published meters: data volume and connector instances. Estuary counts data each time it is captured from a source and each time it is delivered to a destination. Data produced by transformations also counts toward data volume. Buyers should therefore account for both capture and delivery when estimating measured GB, rather than treating a source-data figure as the complete billing quantity.
Each active source or destination is a connector instance, prorated by the hour. Cloud charges $100 per connector instance per month through the sixth instance and $50 per month for each instance after the sixth. The rate structure is therefore not a single flat connector price at every connector count.
Developer includes up to 10 GB per month and two connector instances free of charge. Moving beyond that level starts a 30-day Cloud trial. Cloud is monthly pay-as-you-go and can be stopped at any time. Enterprise is a custom annual-contract offering with discounts; its pricing depends on data volume, connector instances, deployment model, contract length, and support needs. Private and BYOC deployment require an annual or multi-year Enterprise contract, and Estuary's pricing page states that buyers should contact sales for an Enterprise quote.
Cost Estimates by Team Size
Estuary's public Cloud price is based on workload, not team size. The two billing inputs are measured data volume and active connector instances. Data is counted at capture and delivery, including data produced by transformations. Each active source or destination is one connector instance, prorated by the hour. As a result, a useful estimate needs the expected captured and delivered volume as well as the number of active sources and destinations.
The published Cloud rate is $0.50 per GB, plus $100 per connector instance per month through the sixth instance and $50 per month for each instance after that. The official calculator example shows an estimated price of $250 per month for 100 GB of data moved and two connector instances. This is a workload example, not a per-user or team-size price.
Developer provides up to 10 GB per month and two connector instances at no cost, with no credit card required. Cloud starts a 30-day free trial when usage goes past that level. Enterprise does not publish a standard per-GB or per-connector rate: it uses an annual contract with discounts. For Enterprise, private deployment, or BYOC, confirm the committed volume, connector count, deployment model, contract term, and support needs; private and BYOC are available on annual or multi-year Enterprise contracts.
How Estuary Flow Pricing Compares
Our research supports Estuary's pricing and plan structure, but it does not provide a like-for-like pricing basis for another vendor. A direct vendor comparison would require that vendor's own pricing meters, published rates, free-tier limits, deployment terms, and support terms.
For Estuary, Cloud is priced at $0.50 per GB plus connector-instance charges: $100 per month for each instance through the sixth and $50 per month for each instance after the sixth. Data is measured when it is captured and delivered, including data produced by transformations. An active source or destination is a connector instance, prorated by the hour. Developer is free up to 10 GB per month and two connectors, while Cloud is monthly pay-as-you-go and starts with a 30-day free trial when usage exceeds Developer.
Enterprise is a custom annual-contract option with discounts. It adds private and BYOC deployment, SSO, a SOC 2 report, HIPAA BAA, dedicated support, custom SLAs, and migration assistance. Public deployment is listed in US, EU, and APAC regions across all plans. Private and BYOC deployments are Enterprise options on annual or multi-year contracts, so a comparison should separately evaluate the required deployment model, data volume, connector count, contract length, and support requirements.
