The Most Powerful Online Go Compiler

PlayCode's Go compiler is trusted by developers worldwide for learning, prototyping, and practicing algorithms. Write and run Go code instantly in your browser with zero setup, no installation, and no waiting. Whether you're learning Go, building microservices, or practicing for coding interviews, our online Go compiler provides everything you need.

Unlike traditional online Go compilers that run code on remote servers, PlayCode runs Go entirely in your browser using Yaegi, a Go interpreter compiled to WebAssembly. This means your code stays private, execution is instant, and you can even work offline after the initial load.

What is a Go Compiler?

A Go compiler translates your Go source code into executable machine code. Go (also known as Golang) is a statically typed, compiled language designed at Google for simplicity, efficiency, and reliability. PlayCode's online Go compiler uses Yaegi, a powerful Go interpreter that provides near-native compatibility with the Go language.

This means you get full Go language support including goroutines, channels, interfaces, structs, slices, maps, and the standard library. No configuration, no GOPATH setup, no module initialization. Just write Go and run it.

For other languages, try our Python Compiler or C++ Compiler.

Write Go with Full Standard Library

Unlike other online Go compilers that only support basic code, PlayCode includes most of the Go standard library. Use the packages you need to build real applications.

Core Packages

fmt, strings, strconv, sort, math, time, and more.

Data Structures

Slices, maps, structs, interfaces, and custom types.

Concurrency

Goroutines and channels (limited support in browser).

package main

import (
     "fmt"
     "sort"
 )

funcmain() {
     numbers := []int{5, 2, 8, 1, 9}
     sort.Ints(numbers)
     fmt.Println(numbers) // [1 2 5 8 9]
 }

100% Browser-Based Execution

PlayCode is the only Go compiler that runs 100% in your browser. Our technology uses Yaegi, a Go interpreter compiled to WebAssembly. When you click Run, your code is interpreted locally. Nothing is sent to any server.

This provides several advantages: instant execution with no network latency, complete privacy for your code, offline capability after initial load, and no rate limits. You can run your Go code as many times as you want without any restrictions.
