What is it?

Encore is an infrastructure SDK for TypeScript and Go backends. You declare resources such as SQL databases, Pub/Sub topics, object storage buckets, caches, cron jobs and secrets directly in application code. Running `encore run` starts the whole application locally with real Postgres and a local dashboard that shows distributed traces, and the same declarations are provisioned as RDS, Cloud SQL, S3, GCS or equivalent services on deploy.

The SDK is open source and can be used without Encore's managed platform. The optional platform connects to your own AWS or GCP account, provisions resources, creates per-PR preview environments, and derives least-privilege IAM from code paths. Teams that do not use the platform can run `encore build docker` and manage infrastructure with Terraform or other tools. Python and Rust support is listed as upcoming.

Key features

  • 01Declare databases, Pub/Sub, buckets, caches, cron jobs and secrets in TypeScript or Go code.
  • 02Run the whole application locally with real Postgres and a built-in tracing dashboard.
  • 03Provision matching resources on AWS or Google Cloud when deploying.
  • 04Generate per-PR preview environments with optional database branching.
  • 05Build a standalone Docker image for self-hosting with your own infrastructure tooling.

Use cases

  • Building new backend services in TypeScript or Go without writing cloud infrastructure configuration by hand.
  • Giving AI coding agents a local environment with real infrastructure to validate changes against.
  • Adding Encore-built services alongside an existing system, migrating one service at a time.
  • Teams that want to keep application data and infrastructure inside their own AWS or GCP account.

Quick start

  1. 1

    Scaffold a project

    encore app create
  2. 2

    Enter the project folder

    cd myapp
  3. 3

    Run locally with infrastructure and dev dashboard

    encore run

Things to know

  • Fully automated cloud provisioning supports only AWS and Google Cloud; Azure is on the roadmap.
  • Services must be written in TypeScript or Go to use the infrastructure SDK; Python and Rust are not yet available.
  • The managed deployment platform is a commercial service, separate from the open-source SDK.
