How Can We Help?

Estuary allows you to set up low-latency, real-time data pipelines without leaving your batch data behind. Our focus is on simplicity, reliability, and efficiency. See the difference in our detailed comparisons.

Yes. Estuary offers a free tier that includes a generous data volume limit so you can try real-time pipelines without entering a credit card. If you exceed the free tier limits, you can continue to use Estuary for a 30-day free trial. If you need more time or volume during evaluation, just contact us and we’ll help.

Estuary offers 200+ source and destination connectors across databases, cloud storage, APIs, SaaS apps, and streaming platforms. You can view the full connector list here. Don’t see what you need? Reach out — we prioritize connectors based on customer demand.

If we don’t currently support a specific source, you can request it through our support form. You can also use our webhook, file drop (CSV, JSON), or custom HTTP connector to ingest data from virtually any source.

Estuary uses change data capture (CDC) to stream inserts, updates, and deletes from supported databases. For APIs, we pull data incrementally or via webhooks. All changes are written to a real-time collection and delivered downstream continuously.

Estuary syncs data in real time by default. As soon as a change is detected in your source, it is processed and delivered to your destination in seconds. Or set a sync schedule to balance data freshness with compute costs in your destination systems.

Yes. When a pipeline starts, Flow performs a historical backfill to capture your existing data, then seamlessly switches to real-time CDC. Backfilling is configurable and can be disabled or scoped for large datasets.

You can view pipeline status, latency, and metrics in the Flow web app. For advanced monitoring, we expose metrics via an OpenMetrics API, which integrates with Prometheus, Datadog, and other observability tools.

Yes. Estuary supports real-time transformations using SQL or TypeScript. You can filter, enrich, join, and reshape data in motion. Or ditch the code and rename or remove fields directly through the dashboard.

Yes. Estuary offers a dbt Cloud integration. Trigger dbt jobs automatically whenever there’s new data available.

A derivation is a transformation task that creates a new collection based on one or more input collections. It runs continuously and updates automatically as source data changes, supporting real-time use cases.

Yes. You can preview and validate derivations in the UI or CLI using sample data. This makes it easy to catch issues and ensure accuracy before publishing to production.

Estuary provides intelligent schema evolution for durable pipelines with auto-discovery. You can automatically discover new fields, changed data types, and even entirely new data streams. Or you can choose to manually make updates for tight control over your data ecosystem.

Estuary is SOC 2 Type II certified with zero exceptions and HIPAA-compliant. This means our infrastructure and operational controls are independently audited and validated to meet strict industry standards. Learn more here.

Data is stored in your own cloud account, not in Estuary’s. Whether you’re using SaaS or a Private Deployment, your data flows through infrastructure you control, within regions you select. The platform supports zero data egress from your network.

Private Deployments let you run the data plane inside your own VPC or cloud region, while the SaaS control plane manages configuration. Your data never leaves your network, and you retain full control over infrastructure, security, and governance.

Yes. Estuary supports AWS PrivateLink, VPC peering, and SSH tunnels, enabling secure connections to firewalled databases and private cloud services. You can deploy the data plane in any region while maintaining full network isolation.

All communications use TLS, including within cloud environments. Internal services authenticate with mutual TLS (mTLS) using a custom certificate authority per deployment. Server-facing services use Let’s Encrypt, and all data at rest is encrypted with AES-256.

Yes. Estuary uses RBAC (Role-Based Access Control) and tokenized cross-deployment access. The control plane handles authorization and generates traceable, time-limited tokens, ensuring secure access and full auditability across data planes.

Yes. Platform-level logs are shipped from each data plane to a centralized logging system, and task-level logs are accessible via the Flow interface. This enables both internal security monitoring and user visibility.

Yes. Estuary’s architecture supports multi-region data plane mobility without relying on specific VPC constructs. You can maintain consistent security policies across geographies while ensuring data residency compliance.

Estuary pricing is volume and connector-based. You’re billed for the amount of data synced across your pipelines, measured in GBs, plus a flat rate per month based on your number of active connector instances. This makes pricing predictable and scalable. View pricing here.

You will automatically start your 30-day free trial and can upgrade your account at any time. If you go over the free tier limits, you’ll receive a warning and can choose to continue with usage-based billing or pause pipelines.

You can reach out through our Slack, or email us at support@estuary.dev. We also provide enterprise-grade support with SLAs on paid plans.
