Synapse is Artefact's shared Claude Code server — one Claude Team seat, several of us, one connected nervous system. Paste the invite Alex sent you to get a one-line installer.
Step 01 — Activate your access
Paste your invite
Your invite is one-time-use and pre-bound to a private Linux account on Synapse — your terminal, your skills, your memory. The Claude Team seat that powers claude is shared (that's the whole point), and Alex assigns it for you — you don't pick one.

Step 02 — Run the installer
Paste this in Terminal.app
Open Terminal (Spotlight → "Terminal") and paste. The script is idempotent — safe to re-run.

Step 03 — What the installer does
No magic, just steps.
Detects your platform (macOS, Linux, or Windows), installs prerequisites if needed (Homebrew on Mac, winget on Windows).
Installs Visual Studio Code (skips if already there).
Generates an SSH key at ~/.ssh/synapse_ed25519 (no passphrase, OS-level perms protect it).
Posts your public key to Synapse with your invite token. The server resolves which Linux account the invite belongs to, creates it (with the workspace clone), and adds your key to authorized_keys.
Creates ~/Synapse.code-workspace, pointing to your home directory on Synapse via VS Code Remote Tunnels.
Opens VS Code with the workspace file. The only manual step left is approving GitHub OAuth for tunnels — one click, one time.
From here on: double-click the workspace file (Dock on Mac, taskbar on Windows) to land on Synapse. Zero auth, zero menus.

Quebec data, Quebec metal.
Synapse runs on a dedicated server in Beauharnois, QC (OVH BHS7). All conversations, code, and artifacts stay on Canadian soil. Each Linux account is isolated — your terminal history, your Claude conversations, your SSH keys are yours alone. The Claude Team seat that runs claude is the only thing pooled.
