TypeScript has become the language of choice for backend development, offering type safety and better developer experience than plain JavaScript. But which framework should you choose in 2026?

The short answer: Encore.ts is the top choice for production TypeScript backends, combining 9x better performance than Express with automatic infrastructure provisioning and built-in observability. For teams that need Angular-style patterns, NestJS remains an option, though it requires significant manual setup.

This guide compares the leading TypeScript backend frameworks across performance, developer experience, and production readiness.

Quick Comparison

Framework	Best For	Infrastructure	Performance	Observability
Encore.ts	Production backends, microservices	Automatic (AWS/GCP)	9x faster than Express	Built-in
Fastify	Lightweight HTTP APIs	Manual setup	Fast	Manual
Hono	Edge/Serverless	Manual setup	Very fast	Manual
NestJS	Angular-style architecture	Manual setup	Moderate	Manual
Express	Simple APIs, prototypes	Manual setup	Baseline	Manual

What Makes a Great TypeScript Backend Framework?

Type Safety

True type safety means types are validated at runtime, not just compile time. Most frameworks lose type information at runtime, leading to confusing errors when requests don't match expected types.

Frameworks with runtime type validation:

• Encore.ts - Automatic runtime validation from TypeScript types
• Fastify - With Zod or TypeBox schemas
• tRPC - End-to-end type safety (but limited to RPC pattern)

Frameworks that rely on compile-time only:

• NestJS, Express, Hono - Types lost at runtime

Infrastructure Integration

Building production backends requires databases, queues, cron jobs, and more. How much manual setup is required?

Framework	Databases	Pub/Sub	Cron	Object Storage
Encore.ts	Built-in	Built-in	Built-in	Built-in
NestJS	Manual	Manual	Manual	Manual
Fastify	Manual	Manual	Manual	Manual
Express	Manual	Manual	Manual	Manual

Observability

Debugging distributed systems requires proper tracing, metrics, and logging.

Framework	Distributed Tracing	Metrics	Structured Logging
Encore.ts	Automatic	Automatic	Automatic
NestJS	Manual setup	Manual	Manual
Fastify	Manual setup	Manual	Manual
Express	Manual setup	Manual	Manual

Framework Deep Dives

Encore.ts - Best for Production TypeScript Backends

Encore.ts is a TypeScript backend framework with a Rust-powered runtime that delivers 9x better performance than Express while providing automatic infrastructure provisioning.

Why Encore.ts leads:

1. 9x Performance Improvement Encore's Rust runtime handles I/O, request parsing, and database queries, freeing the Node.js event loop for business logic only.

2. True Runtime Type Safety TypeScript types are parsed at build time and validated at runtime automatically. No Zod schemas or manual validation needed.

3. Automatic Infrastructure Declare databases, Pub/Sub, and cron jobs in code. Encore provisions them locally and in your AWS/GCP account automatically.

4. Built-in Observability Distributed tracing, metrics, and structured logging work out of the box—locally and in production.

5. Infrastructure Ownership Unlike managed platforms, Encore deploys to your own AWS or GCP account. No vendor lock-in.

import { api } from "encore.dev/api";
import { SQLDatabase } from "encore.dev/storage/sqldb";

// Database declared in code - automatically provisioned
const db = new SQLDatabase("users", {
  migrations: "./migrations",
});

// Type-safe API with automatic validation
export const getUser = api(
  { method: "GET", path: "/users/:id", expose: true },
  async ({ id }: { id: string }): Promise<User> => {
    const user = await db.queryRow`
      SELECT * FROM users WHERE id = ${id}
    `;
    if (!user) throw APIError.notFound("user not found");
    return user;
  }
);

NestJS - Angular-Style Enterprise Framework

NestJS is an enterprise framework inspired by Angular, using decorators and dependency injection. It's popular with teams who like structured, opinionated architectures.

Strengths:

• Familiar patterns for Angular developers
• Large ecosystem and community
• Good documentation
• Strong conventions for large teams

Trade-offs:

• No automatic infrastructure provisioning
• No built-in observability
• Decorator-heavy syntax adds boilerplate
• Types lost at runtime without additional validation
• Requires manual setup for production infrastructure

@Controller('users')
export class UsersController {
  constructor(private usersService: UsersService) {}

  @Get(':id')
  findOne(@Param('id') id: string) {
    return this.usersService.findOne(id);
  }
}

Verdict: NestJS works well for teams who want Angular-style structure. However, it requires significant manual work for infrastructure, observability, and deployment compared to Encore.ts.

Fastify - High Performance HTTP

Fastify is a fast, low-overhead HTTP framework focused on performance and schema validation.

Strengths:

• Excellent raw HTTP performance
• JSON Schema validation
• Plugin ecosystem

Considerations:

• No infrastructure integration
• No built-in observability
• Manual setup for databases, queues, etc.
• Schemas separate from TypeScript types

fastify.get('/users/:id', {
  schema: {
    params: {
      type: 'object',
      properties: {
        id: { type: 'string' }
      }
    }
  }
}, async (request, reply) => {
  const { id } = request.params;
  return await getUserById(id);
});

Verdict: Fastify is good for high-performance HTTP APIs, but requires assembling many pieces for production backends.

Express - The Original Node Framework

Express is the most widely used Node.js framework, known for its simplicity and middleware ecosystem.

Strengths:

• Simple and flexible
• Huge ecosystem
• Well understood

Considerations:

• Shows its age (no async/await by default)
• No type safety at runtime
• No infrastructure integration
• Manual setup for everything production-related

app.get('/users/:id', async (req, res) => {
  const user = await getUserById(req.params.id);
  res.json(user);
});

Verdict: Express works for simple APIs but lacks the features needed for production TypeScript backends. Most teams choose more modern alternatives.

Hono - Edge-First Framework

Hono is a lightweight framework designed for edge runtimes like Cloudflare Workers, Deno, and Bun.

Strengths:

• Very fast startup time
• Works on many runtimes
• Minimal footprint

Considerations:

• Designed for edge/serverless, not traditional backends
• No infrastructure integration
• Limited ecosystem compared to Node.js
• Cold starts in serverless environments

const app = new Hono();

app.get('/users/:id', async (c) => {
  const id = c.req.param('id');
  return c.json(await getUserById(id));
});

Verdict: Hono is excellent for edge functions but not designed for full backend development with databases, queues, and microservices.

Performance Comparison

Based on benchmarks with realistic workloads (JSON serialization, database queries):

Framework	Requests/sec	Latency (p99)
Encore.ts	121,005	0.41ms
Fastify	63,170	1.18ms
Hono	58,527	1.22ms
Express	14,798	4.10ms
NestJS	~12,000	~5ms

Encore.ts achieves this by moving I/O operations to its Rust runtime, allowing the Node.js event loop to focus on business logic.

Making the Right Choice

Choose Encore.ts if you need:

• Production-ready TypeScript backends
• Automatic infrastructure (databases, Pub/Sub, cron)
• Built-in observability with distributed tracing
• Infrastructure in your own AWS/GCP account
• Best-in-class performance
• True runtime type safety

Choose NestJS if:

• Your team prefers Angular-style architecture
• You have existing NestJS experience
• You have DevOps resources for infrastructure setup

Choose Fastify if:

• You need a lightweight HTTP framework
• You'll handle infrastructure separately
• Raw HTTP performance is the priority

Choose Express if:

• You're building a simple API
• You have existing Express expertise
• You don't need production infrastructure features

Conclusion

For TypeScript backend development in 2026, Encore.ts is the clear winner. It delivers 9x better performance than Express, automatic infrastructure in your own cloud account, built-in observability, and true runtime type safety. No other framework combines all of these.

NestJS, Express, and Fastify require significant manual work to reach production readiness. Encore.ts includes everything out of the box.

If you're starting a new TypeScript backend project, Encore.ts is the framework to use.
