Designed to remove boilerplate, increase productivity, and provide a seamless developer experience, Encore simplifies backend development with built-in cloud infrastructure and developer tools.
Table of Contents
Encore is not just a framework. It’s an opinionated platform that integrates backend logic, APIs, infrastructure provisioning, observability, and DevOps into a single cohesive workflow. Whether you’re building microservices or monolithic applications, Encore offers a fully typed environment for building production-grade backends quickly and efficiently.
What is Encore.ts?
Encore.ts is an open-source backend framework written in TypeScript that allows developers to define APIs and backend logic using native language constructs. It automatically handles routing, documentation, infrastructure provisioning, and observability with minimal configuration.
Built by former Spotify engineers, Encore focuses on developer experience, cloud-native workflows, and reliability. It aims to solve the pain points of modern backend development by reducing complexity and avoiding fragmented toolchains.
Key Philosophy: Encore.ts treats your code as the source of truth. It parses your backend code to generate API routes, deploy infrastructure, and monitor services — no YAML, no separate CI scripts, no separate observability tools.
Core Features of Encore.ts
- Type-Safe APIs: Define APIs using native TypeScript functions. Encore.ts automatically infers request and response types, eliminating the need for external schema definitions.
- Automatic Infrastructure: Encore provisions services like PostgreSQL, Redis, Pub/Sub, etc., based on how they are used in your code — no manual configuration or Terraform scripts required.
- Built-in Observability: Gain instant access to logs, traces, metrics, and service maps with zero setup. Encore.ts injects observability tooling during runtime to monitor performance and failures.
- Microservices & Monolith Support: You can build monoliths, modular services, or a full-fledged microservices architecture. Encore.ts handles inter-service communication and service discovery.
- Cloud-Native by Default: Deploy your app to Encore Cloud (free tier available) or export to any cloud provider (AWS, GCP, Azure) using Docker or Kubernetes.
- Automatic Documentation: Encore generates OpenAPI documentation directly from your code, ensuring consistency between implementation and documentation.
Benefits of Using Encore.ts
- Accelerated Development : Encore speeds up backend development with intuitive frameworks, well-defined abstractions, and robust local development tools, enabling teams to build and iterate faster.
- Scalability and High Performance: Designed for modern, distributed systems, Encore simplifies the creation of scalable microservices architectures—eliminating boilerplate code and reducing complexity as your user base grows.
- Centralized Control and Standardization: With built-in features like automated architecture diagrams, infrastructure tracking, and approval workflows, Encore gives teams and stakeholders clear visibility and control over the entire application lifecycle.
- Enhanced Security and Compliance: Encore Cloud enforces security best practices by default—such as least privilege IAM policies and cloud-specific infrastructure provisioning—to help ensure compliance and safeguard your applications.
- Optimized Costs and Reduced DevOps Burden: By automating infrastructure management, Encore Cloud minimizes unnecessary cloud spend and reduces the operational load on DevOps teams, enabling more efficient resource use.
Architecture Overview
Encore’s architecture centers on code as the source of truth. Here’s a breakdown:
| Component | Description |
|---|---|
| API Definition | Functions with @api() decorator expose HTTP endpoints. |
| Service Communication | Uses internal RPC for microservices and background tasks. |
| Infrastructure Provisioning | Provisions services based on usage (e.g., declaring PostgreSQL.newDatabase()). |
| Observability Layer | Automatically tracks metrics, logs, and traces via the Dev Dashboard. |
| Deployment Engine | Supports Encore Cloud, Docker, and Kubernetes deployments. |
Installation Guide
System Requirements
- Node.js v18+ (Recommended: Node.js v20 LTS)
- npm v9+
- Git
- Encore CLI
- Optional: Docker (for custom cloud deployments)
1. Install the Encore CLI
You can install Encore using npm or Homebrew.
- macOS: brew install encoredev/tap/encore
- Linux: curl -L https://encore.dev/install.sh | bash
- Windows: iwr https://encore.dev/install.ps1 | iex
To verify the installation:
2. Create a New Project
Use the Encore CLI to scaffold a new backend project:
This creates a full-stack-ready backend project with a sample API and development configuration.
3. Run the App Locally
Start your development server:
Now, here’s the cool thing that makes Encore.ts stand out. Once you run the code, it automatically launches an application dashboard at: http://localhost:9400/encore-starter-4t72/requests. See below screenshot for example output:
Deploy to Encore Cloud (Free Tier)
You’ll get:
-
A live endpoint
-
Auto-provisioned infrastructure
-
Metrics, logs, and observability out of the box
Use Cases
Encore is well-suited for:
-
Startups & MVPs – Rapidly build backends with production-ready infrastructure.
-
Internal Tools – Perfect for CRUD APIs with full observability.
-
Microservices – Build and scale distributed systems with minimal configuration.
-
Event-Driven Applications – Support for background tasks and pub/sub patterns.
Advantages and Disadvantages of Encore.ts
Advantages
-
TypeScript-First and Type-Safe by Design
Encore is built entirely in TypeScript, which provides strong type safety across services, APIs, and infrastructure. Developers can define request/response types directly in TypeScript, helping reduce runtime bugs and making code more maintainable.Automatic -
Infrastructure Provisioning
Encore provisions services like PostgreSQL, Redis, and Pub/Sub automatically from your codebase. You don’t need to manually manage YAML, Terraform, or separate infrastructure-as-code tools—Encore handles it behind the scenes. -
Built-in Observability (Tracing, Metrics, Logs)
Every Encore app includes distributed tracing, structured logs, service-level metrics, and a visual dependency graph. These tools are available without extra configuration, giving teams deep insight into how their services interact. -
No YAML or Configuration Boilerplate
Developers write backend logic and infrastructure declarations in pure TypeScript—no external configuration files needed. This makes projects cleaner, reduces duplication, and simplifies onboarding. -
CI/CD and Preview Environments Built-In
Encore provides native GitHub integration to enable CI/CD pipelines, environment-specific secrets, and automatic preview environments for every pull request. This streamlines DevOps for small and mid-sized teams. -
Cloud-Agnostic with Export Capability
While Encore supports deployment to its managed cloud, it also allows exporting to Docker and Kubernetes, giving teams full flexibility to self-host or migrate to AWS, Azure, or GCP. -
Ideal for Startups and MVPs
With its rapid setup, auto-provisioning, and scalable backend structure, Encore is a great choice for fast-moving startups or prototyping new ideas with production-ready code.
Disadvantages
-
Smaller Community and Ecosystem
Encore is relatively new compared to frameworks like Express or NestJS. This means fewer plugins, community resources, and third-party tutorials, which may be a hurdle for some teams. -
Heavy Dependence on Encore Cloud Features
While Encore is open-source and supports Docker/Kubernetes export, many powerful features like observability, preview environments, and CI/CD are tightly integrated with Encore Cloud. Organizations with custom infrastructure may find this restrictive. -
No Built-in Frontend or SSR Support
Encore.ts is focused solely on backend development. It doesn’t include frontend tools like templating engines or server-side rendering (SSR). You’ll need a separate frontend stack like Next.js or React. -
May Not Fit Traditional DevOps Workflows
For teams deeply invested in tools like Terraform, Helm, or custom CI pipelines, Encore’s abstracted infrastructure approach may feel limiting or redundant, especially in highly regulated or enterprise environments.
Encore.ts vs Other Frameworks
| Feature | Encore.ts | NestJS | Express | Serverless Framework |
|---|---|---|---|---|
