export async function GET(request: Request) {
const { searchParams } = new URL(request.url);
const page = parseInt(searchParams.get("page") || "1");
const limit = 20;
const users = await db.user.findMany({
skip: (page - 1) * limit,
take: limit,
orderBy: { createdAt: "desc" },
});
return NextResponse.json({ users, page, limit });
}
export async function POST(request: Request) {
const body = await request.json();
const user = await db.user.create({
data: {
name: body.name,
email: body.email,
},
});
return NextResponse.json(user, { status: 201 });
}
When to Use

app.use(express.json());
app.get("/api/products", async (req, res) => {
try {
const products = await db.product.findAll();
res.json(products);
} catch (error) {
res.status(500).json({ error: "Internal server error" });
}
});
app.post("/api/products", async (req, res) => {
const { name, price, description } = req.body;
if (!name || !price) {
return res.status(400).json({ error: "Name and price are required" });
}
const product = await db.product.create({ name, price, description });
res.status(201).json(product);
});
app.listen(3000, () => console.log("Server running on port 3000"));
When to Use
- Simple REST APIs
- Microservices
- You need maximum middleware compatibility
- Rapid prototyping
4. Hono
Language: TypeScript Best for: Edge computing, serverless, multi-runtime APIs

Example: Edge-Ready API
import { Hono } from "hono";
import { cors } from "hono/cors";
import { jwt } from "hono/jwt";
import { zValidator } from "@hono/zod-validator";
import { z } from "zod";
const app = new Hono();
app.use("/*", cors());
app.use("/api/*", jwt({ secret: "your-secret" }));
const createTaskSchema = z.object({
title: z.string().min(1).max(200),
priority: z.enum(["low", "medium", "high"]),
dueDate: z.string().datetime().optional(),
});
app.post(
"/api/tasks",
zValidator("json", createTaskSchema),
async (c) => {
const data = c.req.valid("json");
const userId = c.get("jwtPayload").sub;
const task = await db.task.create({ ...data, userId });
return c.json(task, 201);
}
);
export default app;
When to Use
- Edge and serverless deployments
- You want to deploy to Cloudflare Workers, Vercel Edge, or Deno Deploy
- You need maximum portability across runtimes
- Performance-critical APIs

- Massive ecosystem of packages
Example: Django REST Framework API
# models.py
from django.db import models
class Article(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
author = models.ForeignKey("auth.User", on_delete=models.CASCADE)
published = models.BooleanField(default=False)
created_at = models.DateTimeField(auto_now_add=True)
# serializers.py
from rest_framework import serializers
class ArticleSerializer(serializers.ModelSerializer):
class Meta:
model = Article
fields = ["id", "title", "content", "author", "published", "created_at"]
read_only_fields = ["author"]
# views.py
from rest_framework import viewsets, permissions
class ArticleViewSet(viewsets.ModelViewSet):
queryset = Article.objects.all()
serializer_class = ArticleSerializer
permission_classes = [permissions.IsAuthenticatedOrReadOnly]
def perform_create(self, serializer):
serializer.save(author=self.request.user)
6. Spring Boot
Language: Java/Kotlin Best for: Enterprise applications, large-scale systems
Spring Boot is the dominant framework for enterprise Java development. In 2026, Spring Boot 3.x with GraalVM native compilation has closed the gap on startup time and memory usage.
Example: REST Controller

@RequestMapping("/api/orders")
public class OrderController {
@Autowired
private OrderService orderService;
@GetMapping
public ResponseEntity<Page<OrderDTO>> getOrders(
@RequestParam(defaultValue = "0") int page,
@RequestParam(defaultValue = "20") int size) {
return ResponseEntity.ok(orderService.findAll(PageRequest.of(page, size)));
}
@PostMapping
public ResponseEntity<OrderDTO> createOrder(@Valid @RequestBody CreateOrderRequest request) {
OrderDTO order = orderService.create(request);
return ResponseEntity.status(HttpStatus.CREATED).body(order);
}
}
When to Use
- Large enterprise applications
- Teams with Java/Kotlin expertise
- You need robust transaction management
- Microservices with Spring Cloud
7. Go Fiber
Language: Go Best for: High-performance APIs, real-time applications
Fiber is an Express-inspired web framework for Go that delivers exceptional performance. Go's compiled nature, goroutines, and minimal memory footprint make Fiber ideal for high-throughput APIs.
Example: API with Fiber
package main
import (
"github.com/gofiber/fiber/v2"
"github.com/gofiber/fiber/v2/middleware/cors"
)
func main() {
app := fiber.New()
app.Use(cors.New())
app.Get("/api/users/:id", func(c *fiber.Ctx) error {
id := c.Params("id")
user, err := db.GetUser(id)
if err != nil {
return c.Status(404).JSON(fiber.Map{"error": "User not found"})
}
return c.JSON(user)
})
app.Post("/api/users", func(c *fiber.Ctx) error {
var input CreateUserInput
if err := c.BodyParser(&input); err != nil {
return c.Status(400).JSON(fiber.Map{"error": err.Error()})
}
user, err := db.CreateUser(input)
if err != nil {
return c.Status(500).JSON(fiber.Map{"error": "Failed to create user"})
}
return c.Status(201).JSON(user)
})
app.Listen(":3000")
}
When to Use
- High-throughput APIs (100K+ requests/second)
- Go teams
- Microservices needing minimal memory footprint
- Real-time applications
8. Elysia
Language: TypeScript Best for: Bun-native high-performance APIs
Elysia is built specifically for the Bun runtime, delivering exceptional TypeScript performance with end-to-end type safety.
Example
import { Elysia, t } from "elysia";
const app = new Elysia()
.get("/", () => "Hello from Elysia!")
.post(
"/api/messages",
({ body }) => {
return { id: crypto.randomUUID(), ...body, createdAt: new Date() };
},
{
body: t.Object({
content: t.String({ minLength: 1 }),
sender: t.String(),
}),
}
)
.listen(3000);
console.log(`Running at ${app.server?.hostname}:${app.server?.port}`);
9. ASP.NET Core
Language: C# Best for: Enterprise applications, Windows ecosystem, high-performance APIs
ASP.NET Core delivers top-tier performance with the productivity of C# and the .NET ecosystem.
Example: Minimal API
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddDbContext<AppDbContext>();
var app = builder.Build();
app.MapGet("/api/products", async (AppDbContext db) =>
await db.Products.ToListAsync());
app.MapPost("/api/products", async (Product product, AppDbContext db) =>
{
db.Products.Add(product);
await db.SaveChangesAsync();
return Results.Created($"/api/products/{product.Id}", product);
});
app.Run();
10. Ruby on Rails
Language: Ruby Best for: Rapid prototyping, startups, MVPs
Rails continues to be one of the most productive frameworks for building web applications quickly. In 2026, Rails 8 brought significant performance improvements and modern features.
Example: API Controller
# app/controllers/api/v1/posts_controller.rb
class Api::V1::PostsController < ApplicationController
def index
posts = Post.includes(:author)
.page(params[:page])
.per(20)
render json: posts, include: [:author]
end
def create
post = current_user.posts.build(post_params)
if post.save
render json: post, status: :created
else
render json: { errors: post.errors.full_messages }, status: :unprocessable_entity
end
end
private
def post_params
params.require(:post).permit(:title, :content, :published)
end
end
