What Are the Best Languages to Develop REST APIs in Today's Tech Landscape?

Hey everyone! 👋

So, I’ve been diving into the whole "best languages to develop rest api" debate lately, and man, it’s a rabbit hole. Like, everyone’s got their favs, right?

For me, Node.js is a no-brainer for quick, scalable APIs. It’s just so dang fast and lightweight. But then, Python with Flask or FastAPI is like the chill, easy-to-read option. Like, you can whip up an API in minutes, no sweat.

Then there’s Go—super performant and kinda underrated imo. And Java? Old reliable, but feels a bit heavy for smaller projects.

Honestly, the "best languages to develop rest api" totally depends on what you’re building. Speed? Ease? Scalability? Pick your poison.

What’s your go-to? Am I missing any hidden gems? Let’s hear it! 🚀
Node.js is def a solid choice for building rest apis, especially if you're into async stuff and need something lightweight. But have you checked out Rust? It's gaining traction for its performance and safety features. Not the easiest to learn, but once you get the hang of it, it's a beast for high-performance APIs.

Also, for tools, Postman is a lifesaver for testing APIs, and Swagger for documentation. Both are must-haves imo.
Python with FastAPI is my go-to for quick rest api development. It’s so clean and easy to debug. Plus, the async support is 🔥.

If you’re into performance, though, Go is hard to beat. It’s like the middle ground between speed and simplicity.

For resources, I’d recommend the FastAPI docs (super beginner-friendly) and the Go by Example site. Both are gold.
Honestly, I think the "best languages to develop rest api" debate is kinda overrated. It really depends on your team’s expertise and the project scope.

That said, I’ve been using C# with ASP.NET Core lately, and it’s surprisingly good. Super robust and great for enterprise-level stuff.

For learning, Microsoft’s official docs are pretty solid, and Visual Studio makes the whole process smoother.
Node.js is great, but have you tried Deno? It’s like Node’s cooler, more secure sibling. Still early days, but it’s worth keeping an eye on.

For smaller projects, I’d stick with Python or even PHP with Laravel. Yeah, PHP gets a bad rap, but Laravel makes rest api development a breeze.

Also, Insomnia is a great alternative to Postman if you’re looking for something a bit more modern.
Wow, thanks for all the awesome suggestions, everyone! 🙌

I’ve been playing around with FastAPI and Go based on your recs, and they’re both super fun to work with. FastAPI’s docs are as good as y’all said, and Go’s simplicity is refreshing.

I’m curious though—anyone tried combining multiple languages for different parts of an API? Like, using Go for the core and Python for some lightweight tasks? Would love to hear if that’s a thing or if it’s just overcomplicating stuff.

Also, big shoutout for the tool suggestions—Postman and Insomnia are both 🔥.
Go is my absolute fav for rest apis. It’s fast, simple, and the concurrency model is just *chef’s kiss*.

If you’re into microservices, Go + Docker is a killer combo.

For learning, the official Go tour is a great starting point, and the Go subreddit is super active and helpful.
I’m a big fan of Ruby on Rails for rest api development. It’s not the fastest, but the developer experience is top-notch.

For tools, I’d recommend using Rails API mode and pairing it with GraphQL if you’re feeling fancy.

Also, the Rails Guides are super comprehensive and easy to follow.
Kotlin with Ktor is a hidden gem for rest api development. It’s lightweight, modern, and integrates well with Java libraries if you need them.

For testing, I’d recommend using Ktor’s built-in tools or even JUnit if you’re already in the JVM ecosystem.

Also, JetBrains Academy has some great Kotlin courses if you’re just starting out.
