Litestar Is Worth a Look

Summary

Litestar is worth a look Published on: August 6, 2025 Categories: Django, Python A few years ago at work, I had a project which offered an opportunity to look at the new generation of async-first, type-hint-driven Python web frameworks. For reasons which aren’t particularly relevant today, on that project I ended up choosing Litestar, which is the one that doesn’t have a ravenous all-consuming hype machine surrounding it. And I’m very glad I did, because today I’m more convinced than ever it was the right choice, and for the last 18 months or so every new project I’ve started at my day job has been built with Litestar. But even if you’re someone who does Python web apps for a living, and even if you’re someone who builds asynchronous type-hint-driven web apps, you might not be familiar with this absolute gem of the Python web ecosystem, and today I want to remedy that. A taste Here’s the traditional single-file-app demo: from litestar import Litestar, get @get("/greet") async def greet(name: str) -> str: return f"Hi, {name}!" app = Litestar([greet]) You save this as app.py, run with litestar run or hand it directly to the ASGI server of your choice, and it launches a web application. You go to /greet?name=Bob and it replies “Hi, Bob!”. Leave out the name parameter and it responds with an HTTP 400 telling you the name parameter is required. So what. Big deal. The FastAPI Evangelism Strike Force will be along soon to bury you under rocket-ship emoji while explaining that FastAPI does the same thing but a million times better. And if you’re a Java person used to Spring, or a .NET person used to ASP.NET MVC, well, there’s nothing here that’s new to you; you’ve had this style of annotation/signature-driven framework for years (and in fact one thing I like about Litestar is how often it reminds me of the good parts of those frameworks). And did anyone tell you FastAPI does this, too! 🚀🚀🚀🚀🚀🚀🚀🚀🚀 But there are a lot of things that make Litestar stand out to me in the Python ...
