Go can't run inline (yet)

Some languages need a real compiler or runtime that doesn't fit in a browser. But you can run Go instantly on these free platforms:

Sample Go code:

Go example
// HTTP server in 5 lines
package main
import "net/http"

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("Hello!"))
    })
    http.ListenAndServe(":8080", nil)
}

A note on this playground

Code runs in your browser using open-source engines (Pyodide for Python, native JS for JavaScript, AlaSQL for SQL). Nothing is sent to OneCity's servers. No accounts, no tracking. If you save your work, copy-paste it somewhere else — refreshing the page resets the editor.
