Desktop app

Take Blockwire
off the browser.

The desktop app adds an account you sign in with, real-time LAN multiplayer (host a world, friends join over your network), and multiple saved worlds stored on your own machine. The browser version at blockwire.html stays free and needs nothing installed — this is for playing with other people.

Looking up the latest build…
Unsigned builds. We don't have a code-signing certificate yet, so your OS will flag the app as being from an "unidentified developer." On macOS: right-click the app → Open (or System Settings → Privacy & Security → Open Anyway). On Windows: click More info → Run anyway on the SmartScreen prompt. The source is public — see for yourself there's nothing hiding in it.

Read CLAUDE.md for where the project stands, or grab the file yourself from the releases page if you'd rather not wait on the lookup above.
