What it does

Checked against the code and its tests on 2026-10-24.

#Reach any machine

Open a terminal on your own machine from any browser, on any network that lets the web out. It feels as fast as sitting at it.

• works today A terminal on a Linux machine of yours, in a pane, from any browser.
• works today Wifi drops and the phone takes over: the shell carries on, nothing lost.
• works today It goes direct when the network allows, and through the relay when it doesn't.
• next The machine's desktop in a pane, while the machine itself stays locked.

#Share exactly

You decide who reaches each thing. A person, a device or an agent gets exactly what it was given, and nothing in between can read it.

• works today Your own devices join from one you already trust, and you can revoke any one of them.
• works today The relay forwards sealed bytes, with post-quantum key exchange.
• next Share a folder or a terminal with a person, in one step.
• later Let an agent into one folder until Friday, and see what it did.

#Every copy in sync

Your files on every device you choose, merged when they meet, with no edit lost.

• works today Open a file on any of your machines, from any device, and it saves back there.
• next Choose the devices each folder is kept on, and how many copies.

#Works with what you have

Your files stay plain files in folders, and your devices stay yours. Nothing to convert.

• works today Any browser, a phone's included, with nothing to install.
• works today Linux machines, with one line in a terminal and no root.
• next macOS and Windows machines.
• works today Markdown opens and saves back byte for byte; git sees only the lines you changed.
• later Your own editors and tools on its files, such as VS Code or ssh.

#Easy to start, free to leave

No sign-up and no server of your own. Your data is already in standard formats on your devices, so leaving costs nothing.

• works today Try it: your own account, at an address of its own, in a minute.
• works today No server of your own: the relay forwards for you, and can't read what it carries.
• works today Nothing to export when you leave: your files never left your machines.
• later Run every part yourself, from its open source.

#Arrange your work

Tools tiled side by side, like i3, on a desktop or a phone.

• works today Tiled panes, numbered workspaces and tabs in any pane.
• works today Every action from the keyboard, and also in one click or tap.
• works today On a phone, a deck of panes with a bar to switch them.
• next Your layout comes back on another device, in one step.

#Offline is another place to work

Read and edit with no connection, and it syncs when you're back.

• later Your files readable and editable with no connection.
• later What you changed offline syncs by itself when a connection returns.

#Yours to shape

Each tool useful with no setup, and yours to change.

• works today One launcher opens any tool; held keys show what each one does.
• works today Light and dark, following your system.
• later Change how a tool works, and keep your change.
• later Make a tool of your own, and use it like the built-in ones.

#Together

Work with someone in real time: each sees the other's edit within a second.

• works today Two of your devices edit one file at once, live, and both keep their edits.
• later Share a pane, a workspace or your whole screen with another person.
• later An agent edits beside you, and its changes show like a person's.

#Measure what you care about

Your time, your network and your devices, recorded on your own devices.

• works today Each pane shows whether it goes direct or through the relay.
• later A timesheet of your time in each tool.
• later Each device's CPU, memory and storage, and each link's round trip over time.
