Ask ten Node.js developers which web framework to use, and you'll get at least four different answers. Express is the default for a lot of people. Fastify has a loyal following among those who care about performance and structure. And Hono is the newer name that keeps showing up in discussions about edge computing and modern runtimes.

All three can build a good API. The differences are in philosophy, ecosystem, and the kinds of projects they suit best. If you're starting something new, or wondering whether it's time to move on from what you've been using, it helps to understand what each one is actually good at.

Let's go through them one by one, then compare.

Express

Express has been around for a very long time, and that's its biggest strength. It's the framework most Node.js tutorials, courses, and examples are built on, so there's an answer for almost any question you can think of. The ecosystem of middleware is enormous, from authentication to logging to file uploads.

It's also intentionally minimal. Express gives you routing and a middleware system, and the rest is up to you. That's flexible, but it means you have to decide how to organize your project, how to validate input, and how to handle errors. Because it was designed before modern JavaScript patterns became common, some older-style conventions can feel a bit dated, though it continues to be maintained and used in plenty of new projects.

Fastify

Fastify was built with performance and developer experience in mind. It has a plugin system that encourages you to organize your application into small, reusable parts, which helps larger projects stay tidy.

One of its standout features is built-in support for schema-based validation using JSON Schema. You describe what your requests and responses should look like, and Fastify validates them and can use the same information to speed up serialization and generate documentation. It also has solid logging integration and good TypeScript support.

The trade-off is that the ecosystem is smaller than Express's, and the plugin model takes a little time to get used to. Once it clicks, though, many developers find it a more structured and pleasant way to build APIs.

Hono

Hono is the youngest of the three. It's small and fast, and it's built on web-standard APIs, the same Request and Response objects you'd use in browsers and many modern runtimes. That design lets Hono run in a lot of places, including Node.js, Cloudflare Workers, Deno, and Bun, without major changes.

That portability makes it a favorite for projects that target edge platforms or serverless environments. The API is clean and pleasant, and TypeScript support is strong.

The downside is that, being newer, it has a smaller community and fewer third-party integrations and examples. For common needs, you'll find what you need. For unusual ones, you may be on your own more often than you'd be with Express.

Comparing them where it matters

Ecosystem. Express wins on sheer volume. If you need a specific integration, someone has probably built it for Express already. Fastify has a healthy plugin ecosystem, and Hono's is growing.

Performance. You'll often see Fastify and Hono described as faster than Express in benchmarks, and that's usually true in a narrow sense. But in real applications, the framework is rarely the bottleneck. Database queries, calls to outside services, and your own business logic take far more time than routing. Unless you're handling an unusually high number of simple requests, the framework's raw speed is unlikely to be what decides your performance.

TypeScript. All three can be used with TypeScript. Fastify and Hono put a lot of effort into good typing, while Express relies more on additional type packages and conventions.

Validation. Fastify has it built in. With Express and Hono, you typically add a validation library, which is a perfectly fine approach but one more thing to choose.

Portability. Hono is clearly the most portable across runtimes. If you might deploy to edge or serverless platforms, that's a real advantage.

Learning curve. Express is the most familiar, and many developers already know it. Fastify and Hono are both approachable if you have some Node.js experience.

A few honest warnings

It's easy to over-think this choice. Two things are worth keeping in mind.

First, don't pick a framework based on a benchmark you saw on social media. Those tests usually measure something like "hello world" responses, which isn't how real applications behave.

Second, consider the long term. Whatever you choose, you or your teammates will maintain it for years. A framework with great documentation and a lively community may serve you better than one that's slightly faster on paper.

How to choose

Express may suit you if you value familiarity, want the largest ecosystem, or are working on a team that already knows it well. It's a safe, proven choice, especially for standard APIs.

Fastify may suit you if you want more structure, built-in validation, and strong performance in a traditional server setup. It's a good choice for teams that like conventions and clear organization.

Hono may suit you if you're targeting edge platforms, need to run on multiple runtimes, or like its lightweight, standards-based design.

If you can't decide, spend an afternoon building the same small endpoint, say one that accepts JSON, validates it, and saves it to a database, in each framework. The one that feels most natural to you will tell you a lot.

What switching would involve

People often wonder how painful it would be to move from one framework to another later. The honest answer is that it depends on how tightly your business logic is tied to the framework. If your core logic lives in separate functions and modules, and the framework is mostly the thin layer that receives requests and sends responses, switching is quite manageable. If your logic is spread through framework-specific middleware and handlers, it's a bigger job.

A good habit with any of the three is to keep the framework at the edges. Put validation, database access, and business rules in their own modules, and let the framework simply connect them to HTTP. That keeps your options open.

Middleware, plugins, and how they differ

All three frameworks let you add reusable pieces that run around your handlers, but they call them different things and use them differently. Express uses middleware functions that run in order. Fastify uses plugins, which can be scoped to parts of your app and keep their own encapsulated state. Hono uses middleware built on web-standard requests and responses, so the same pieces can often work across different runtimes.

Understanding this difference helps you read documentation faster and judge whether a library you want will fit. If you rely heavily on existing Express middleware, check whether an equivalent exists for the framework you're considering before you commit.

Testing and developer experience

Testing APIs is straightforward in all three. You can send test requests directly to the app without starting a real server, which keeps tests fast. Fastify and Hono make this especially easy, and Express works well with common testing libraries. Beyond testing, think about everyday comfort: error messages, documentation quality, and how quickly you can find answers when something goes wrong. These small things add up over a long project.

Wrapping up

Express, Fastify, and Hono are all capable choices, and none of them will be the reason your project succeeds or fails. Team experience, your deployment target, and the libraries you need matter far more than small differences in speed. Pick the one that fits your situation, keep your code well organized, and focus on building the actual product.
