Signed with a personal development certificate, not notarized by Apple (that requires a paid Apple Developer account) — macOS will block it on first open.

How to open it
  1. Open the .dmg and drag Burrow into Applications
  2. macOS will say it "cannot be opened" — click Done, don't move it to Trash
  3. Right-click (or Control-click) Burrow in Applications → Open
  4. Click Open again in the dialog that appears — only needed the first time

Linux
Source · .tar.gz · ~200 KB · Debian/Ubuntu

Bluetooth support needs to be compiled on Linux itself, so there's no single prebuilt binary that works everywhere — this is the same source used to build and verify a working .deb (real BLE central + peripheral, end-to-end tested) on Ubuntu.

How to open it
  1. Extract it, then from the extracted folder: sudo apt update && sudo apt install -y build-essential python3 libudev-dev bluez
  2. Install pnpm if you don't have it: curl -fsSL https://get.pnpm.io/install.sh | sh -
  3. Run ./apps/desktop/linux-build/build-deb.sh — this compiles Bluetooth support correctly for your machine
  4. sudo apt install ./apps/desktop/release/Burrow-*.deb, then run: /opt/Burrow/burrow --no-sandbox
