Go Sandbox: A full-featured, IDE-level Go playground — now live and free to use

Hi all, just wanted to share a tool I built for Go developers:

:backhand_index_pointing_right: https://go-sandbox.org

Go Sandbox is a web-based Go programming environment delivering a nearly native development experience enhanced with LSP-powered features:

  • Go-to-definition, reference lookup, autocompletion (via LSP)
  • Real-time code execution over WebSocket
  • Shareable, runnable Go code snippets
  • Code structure outline, multiple sandboxes
  • Vim/Emacs-style keybindings and dark mode
  • Free, zero-registration and setup

It was inspired by the official Go Playground and Better Go Playground, but built with a more IDE-like experience in mind.

Would love to hear your thoughts — feedback and bug reports are very welcome :folded_hands:
