An SDK you and your AI will love

Encore provides structured patterns and built-in infrastructure guardrails, so you and your AI can build production-grade distributed systems with confidence.

✓

Infrastructure Generation

Robust patterns for integrating databases, pub/sub, cron jobs, and more. Encore runs everything locally for you and provisions it seamlessly in preview and production

✓

MCP for Introspection

Built-in MCP server lets AI understand your services, APIs, schemas, and traces

✓

Standardization & Guardrails

Encore's compiler ensures generated code follows established service structures and API conventions

Define your infrastructure as type-safe objects in code

Declare what your application needs directly in TypeScript, and Encore automatically provisions it across local development, preview environments, and production.

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.”
