Bridge

Bridge keeps your Atlas and chats in step across your devices. Sign in on a second computer and you see the chats, Pages, and files from the first one. Every device still runs its own agents. Bridge copies encrypted data between devices. It never runs an agent for you.

​

What you can do

• Edit Atlas anywhere. Start a Page on one device and keep writing it on another. Files and images come along.
• Read chats from your other devices. They appear in the sidebar with the device’s name and whether it is online.
• See your other devices’ Code workspaces. They appear under the matching project.
• Keep working offline. Changes wait on the device and sync when it reconnects.
• Choose what leaves. Keep a project local, or leave your existing history out when you sign in.

Chats from another device are read-only. To act on one, use remote control through Mains Connect.

​

Bridge and Mains Connect

Bridge and Mains Connect solve different problems. You can use both. Bridge does not make a device reachable. Continue with remote control on a synced chat opens Settings → Mains Connect, and that device must already be shared there.

​

What syncs

Files up to 50 MiB sync. Larger files stay on the device that made them.

​

What stays on each device

These never sync:

• Agent sign-ins and provider settings, including API keys.
• Service connections, their tokens, and the tasks and issues they fetch.
• App settings and paired phones.
• Repository files, Git state, and terminals.
• Code projects whose sync you turn off, and history you leave out at sign-in.

Bridge sign-in is separate from agent authentication, service connections, and Git or gh authentication. Signing in to Bridge does not sign in anything else.

​

Limits

When storage is full or beta access ends, you can still read, download, and delete synced data. New changes wait on the device until there is room or access is active again.

​

Where it works

Open Bridge from the navigation rail.

• Mains Desktop on macOS signs in through your browser.
• Mains Server on macOS or Linux signs in through its browser interface or the mains bridge command. See Mains Server.
• The iPhone companion cannot sign in to Bridge or manage its keys. It connects to one backend, as before.

Update every device to Mains 0.20 or newer before you sign in.
