Installing on Windows

Chiselbase isn’t code-signed, so Microsoft Defender SmartScreen warns on the first launch. The warning is titled “Windows protected your PC”. SmartScreen shows it for apps that carry no signature and little download history.

  1. Choose “More info”.
  2. Choose “Run anyway”.

Installing on macOS

The macOS builds aren’t notarized, so Gatekeeper refuses to open Chiselbase the first time. It’s the macOS version of the SmartScreen warning above.

  1. Open Chiselbase once and close the message.
  2. Go to System Settings, then Privacy & Security, and choose “Open Anyway”.
  3. On macOS 14 or earlier, you can also Control-click the app in Applications and choose “Open”.

Or remove the quarantine flag in Terminal:

xattr -d com.apple.quarantine /Applications/Chiselbase.app

Updates are checked differently. Before an update installs, Chiselbase checks its manifest, file size, SHA-256 hash and signature against a public key built into the app. That protects updates. It is not code signing and doesn’t cover this first download.

System requirements

Windows
Windows on x64 or ARM64, with Microsoft Edge WebView2.
macOS
Apple silicon or Intel, with a DMG installer for each architecture.
Linux
x64 or ARM64 as an AppImage. Credentials are stored through Secret Service.

Windows is the primary development and validation platform. macOS and Linux builds are available; platform-specific issues may need additional troubleshooting. Built with Tauri and Rust, Chiselbase uses your system webview rather than bundling a browser.

What happens on first start

  1. Chiselbase opens without an account or sign-up.
  2. It opens in German. Switch the language to English in Settings.
  3. Choose “Connect project” and sign in with a service-account JSON file, Application Default Credentials, your Firebase CLI login or Google sign-in. The emulator needs no credentials.
  4. Chiselbase may find credentials already on your machine. It uses none until you confirm.
  5. Pick the environment label. A new production connection starts write-protected.

The overview of a new development connection. It lists what the credentials may do and whether write protection is on.

Updates

Updates come through the app from the stable channel. Each one passes the manifest, size, SHA-256 and signature checks above before it installs.
