FastAPI vs Express vs Hono: Backend Showdown
FastAPI currently holds a remarkable 96,522 GitHub stars. Express, a long-standing favorite, has a substantial following but lags behind FastAPI in this regard. Hono, the new kid on the block, is just starting to gather steam. But let’s not kid ourselves: stars don’t ship features, and when it comes down to real-world applications, the devil is in the details.
| Framework | Stars | Forks | Open Issues | License | Last Release Date |

| FastAPI | 96,522 | 8,917 | 165 | MIT | 2026-03-23 |
| Express | 61,678 | 11,778 | 40 | MIT | 2026-02-17 |
| Hono | 5,897 | 182 | 1 | MIT | 2026-03-15 |
FastAPI Deep Dive
FastAPI is a modern Python web framework that’s designed to build APIs with high performance. Due to its asynchronous capabilities and type hints, it can handle numerous requests efficiently. This makes it a favorite among developers looking for speed and ease of use—especially when dealing with JSON data. FastAPI promotes quick development cycles while ensuring that your application can handle high throughput.
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
def read_root():
return {"Hello": "World"}
@app.get("/items/{item_id}")
def read_item(item_id: int):
return {"item_id": item_id}
What’s good about FastAPI? First off, the automatic generation of OpenAPI documentation makes it a breeze to understand and interact with your API. The first-class support for asynchronous requests is a huge advantage. You can run multiple requests concurrently without blocking the server thread, giving you real performance gains in high-traffic scenarios.
However, there are downsides. If you’re working on a project that’s not structured properly, the beauty of FastAPI might be lost. The reliance on type hints can also confuse those who come from dynamically-typed languages. If you’re not careful, you might end up wasting time debugging issues that are more related to type mismatches than actual application logic.
Express Deep Dive
Express is the old guard of the Node.js world. Its simplicity and unopinionated nature have made it a staple in many developers’ toolkits. The learning curve for Express is minimal, making it easy for newcomers to get up and running quickly. It provides middleware support that lets you customize the request-response cycle.
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.send('Hello World!');
});
app.get('/items/:itemId', (req, res) => {
res.send({ itemId: req.params.itemId });
});
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
What’s good about Express? Its middleware ecosystem is highly developed. You can find a middleware for almost anything, whether it’s authentication, logging, or handling CORS. It’s lightweight and allows developers to choose the components they want to work with, so you won’t end up with a bloated app.
But let’s be real: as applications scale, Express can become cumbersome. You may find yourself writing boilerplate code for what should be simple functionalities. The callback hell is a real issue, and though it has support for async/await, it isn’t as streamlined as FastAPI’s handling of asynchronous code. The ecosystem can also be overwhelming for newcomers who aren’t sure which middleware to pick.
Hono Deep Dive
Hono is relatively new but has been gaining traction. The main selling point is its focus on offering a minimalistic but powerful API framework for fast HTTP response handling. Built on top of the modern web APIs, Hono promises speed and efficiency with a tiny footprint.
const { Hono } = require('hono');
const app = new Hono();
app.get('/', (c) => c.text('Hello, Hono!'));
app.get('/items/:id', (c) => c.json({ id: c.req.param('id') }));
app.fire();
What’s good about Hono? Its expressiveness. The code is clean, and because it uses a middleware approach, you can easily plug in additional functionalities. Since it’s built with TypeScript, you’ll be less likely to encounter type-related bugs, and it’s highly performant out of the box.
But Hono also suffers from an identity crisis. It doesn’t have the same level of community support or library maturity as either FastAPI or Express. While it’s growing, a smaller user base leads to fewer resources when you run into issues. Additionally, if you’re not familiar with the underlying concepts, the learning curve might still be there.
Head-to-Head Comparison
So, how do these frameworks stack up against each other? Let’s look at some specific criteria: performance, ease of use, community support, and scalability.
Performance
FastAPI wins here, hands down. While Express has decent performance, it’s not built to handle asynchronous calls as efficiently as FastAPI. Hono also claims excellent performance but lacks real-world benchmarks compared to FastAPI.
Ease of Use
Express is arguably the easiest to get started with, especially if you’re already familiar with JavaScript. FastAPI has a learning curve if you’re not used to type hints in Python, but the long-term benefits outweigh the short-term confusion. Hono, while straightforward, still requires a bit of understanding around its APIs, which could throw off newcomers.
Community Support
FastAPI has a vibrant and thriving community. Express, being older, has a plethora of resources available online but can be chaotic. Hono, in contrast, is like a new restaurant in your neighborhood. Everyone’s curious, but not everyone knows it’s there yet. Proceed with caution.
Scalability
FastAPI makes scaling easier due to its async capabilities. While Express can handle traffic well, you might find yourself writing more boilerplate for large applications. Hono is still unproven at scale, as it hasn’t been around long enough to establish a track record.
The Money Question
All three frameworks are open-source and free to use, which is a huge plus. However, hidden costs can arise depending on the ecosystem you choose to enter.
For instance, if you choose to go with FastAPI, you might need to invest in learning more about Python and its accompanying tech stack, which includes databases like SQLAlchemy or Orator. This could amount to developer training or hiring costs if your team isn’t familiar.
With Express, although the framework is free, the reliance on middleware and its ecosystem might lead you to paid services for things like database integrations or authentication. You might find yourself spending more time assembling your stack than actually coding.
Hono is fresh, so its associated costs are yet to be fully realized. You might spend time finessing your setup or looking for community support as you experiment with this framework.
My Take
If you’re a Python enthusiast looking to build high-performance applications, choose FastAPI. It’s hard to argue against the type safety and async capabilities that come packed together. For a quick start in JavaScript, especially if you’re building smaller applications, pick Express. It’s simple and effective for what it does. Finally, if you’re adventurous and want to be at the forefront of something new, give Hono a shot—just beware of its infancy.
For the Solo Developer
If you’re someone flying solo on a project, my recommendation is FastAPI. You’ll capitalize on type hints and be able to quickly iterate on your API, even if you have to learn a bit of Python first. The benefits of Python web frameworks, in general, are numerous.
For the Small Team
If you’re collaborating in a small team of Node.js developers, stick with Express. It has an immense library of middleware options and a developer-friendly approach that won’t put anyone to sleep during discussions.
For the Experimenter
If you fancy being on the latest of technology and aren’t afraid to tackle a steep learning curve, go with Hono. You might end up figuring out a killer way to scale your app while others are still catching up with the latest frameworks.
FAQ
Can I use FastAPI for real-time applications?
Yes, FastAPI supports WebSockets, making it suitable for real-time applications like chat apps and notifications.
Is Express still a good option for new projects?
Yes, especially for small to medium-sized projects. For larger applications, you might want to consider FastAPI or a more specialized framework.
What’s the installation process like for these frameworks?
For FastAPI, you can install it via pip: `pip install fastapi uvicorn`. For Express, you can run `npm install express`. Hono can be installed with `npm install hono`.
Are there any major performance benchmarks comparing these frameworks?
While FastAPI has consistently shown high performance in various tests, you’ll want to check specific benchmarks, as they can vary by use case. Hono is too new for widespread benchmarks but is claimed to be incredibly fast.
