Built-in developer tools

From your application code, Encore automatically generates documentation and architecture diagrams, and provides distributed tracing out of the box.

Service Catalog

Service Catalog with API explorer and auto-generated docs from your TypeScript types.

Architecture Diagrams

Real-time architecture diagrams showing services, APIs, databases, Pub/Sub topics, and their connections.

Distributed Tracing

Built-in tracing for API calls, database queries, and Pub/Sub messages — no instrumentation needed.

Works with your existing stack

No need for a big rewrite

Start small with new services and unlock immediate benefits, then migrate at your own pace.

“Encore is our foundation for all new development. Since adopting it, we've seen a 2–3x increase in development speed and 90% shorter project lead times.”

Josef Sima

Engineering Director, Groupon

“We've run Encore in prod for over 2 years and we've reduced time spent on DevOps by 95%.”

Mason Stewart

CTO, Bookshop.org

“Encore fit the service oriented patterns that we were used to, and let us build a robust backend from day one without worrying about infra, deployments and observability.”
