FIN
Browser-based development tools for the agentic era

Your agent.
Any computer.

The work is over there. You’re right here.
Connect a computer. Give your agent a way in. Get things done.

or

Enter the code from the other computer.

Your lab PC. Your home desktop. Your Pi in the greenhouse.
Work where your software already lives.

A little setup.
A lot within reach.

One computer shares. Another connects.
You approve the connection.

  1. 01

    Share

    On the computer you want to reach, open FIN and choose Share. Open the helper to get a code.

  2. 02

    Enter

    Open finruntime.com on your other device. Enter the code right here.

  3. 03

    Approve

    Confirm on the first computer. You’re connected. Use Disconnect when you’re done.

A bridge to the work

Bring your agent.
Reach your tools.

The apps, scripts, and environments you already use. On the computer where you need them.

Explore the agent API
01 / AGENT ACCESS

Act. Observe. Keep going.

Give your agent a scoped, one-hour credential. Send ordered actions, run commands, and request screenshots to see what happened.

02 / COMMANDS

A command away.

Run a script or check a process on the other computer. Read the output right in your browser. Each command starts a fresh shell.

03 / DESKTOP

See it. Work with it.

Open the remote desktop, use its mouse and keyboard, and work in the apps already running there.

Your computer. Your call.

Access starts with you.

Codes work once and expire after 10 minutes. New code connections need approval on the computer being shared. You can stop access from its FIN controls.

Optional remembered access lets this browser reconnect without a new code. It stays visible in the Windows tray and can be revoked.

A few good questions.

Do I have to install anything?

On the computer you share, download and open a small FIN helper. It gives FIN permission to show and control that computer. The device you connect from only needs a browser.

Windows can remember access after setup. Keep the helper running and the computer signed in, awake, and online.

Does closing the tab stop access?

Use Disconnect to end your session. Closing a tab does not revoke access. If you enabled remembered access, remove it from the session options or disable it from the FIN tray icon when you no longer want it.

Which computers can I share?

Windows, macOS, and Linux, including supported Raspberry Pi setups. macOS needs screen and accessibility permissions. Linux needs a running X11 desktop; Wayland and headless desktops are not supported.

FIN shows the primary display. It cannot control Windows security prompts or a computer that is asleep or signed out.

Is the connection encrypted?

Traffic is encrypted between each device and FIN’s server. It is not end-to-end encrypted: FIN’s server processes screen images, input, and commands to relay your session.

Can I move files or connect an AI agent?

The Agent bridge provides a scoped credential for commands, ordered actions, and screenshots. File transfer and standalone app previews are still planned.
