Less stuff.
More outside.

A little room for your next adventure.

Example only. No purchase or data sent.

Click through the real thing.Check flows and interactions, not just a picture.

Use the device that matters.Try your local app from a phone, tablet, or laptop.

Keep building locally.Your machine runs the app while the preview is live.

02 / Close the loop

Feedback your
agent can use.

“Looks good” is useful. “The checkout button is hard to reach on mobile” is actionable.

Record a verdict and a note in your dashboard. Your agent reads them with previewctl feedback and has the context for its next change.

An approval records your verdict. It does not merge or deploy code. Feedback belongs to the preview, which can keep changing.

03 / A small setup. A better loop.

Connect once.
Review every build.

You'll need a workspace admin, a supported agent machine with Node.js 20.9 or newer, npm, curl, a Bash-compatible terminal, and a local app running on the port you want to share.

  1. 01

    Install the CLI

    On the machine where your agent builds.

    curl -fsSL https://app.agentpreview.dev/api/cli/install.sh | bash
  2. 02

    Connect the machine

    Sign in and approve its pairing code in the dashboard.

    previewctl login
  3. 03

    Publish your local app

    Choose the port your app is running on.

    previewctl publish --port 3000
  4. 04

    Review, then respond

    Open it from your dashboard. Leave feedback for your agent to read.

    previewctl feedback <preview-id>

Good questions

A little more
before you start.

Who can open a preview?

Signed-in members of your workspace can open previews through the dashboard. A raw link alone does not grant review access.

Does my computer need to stay on?

Yes. Your local machine runs the app and the preview connection. Keep it awake and keep the app running while someone reviews.

How does my agent receive the feedback?

Your agent runs previewctl feedback <preview-id> to read recorded verdicts and notes. The CLI also supports waiting for new feedback. It does not automatically resume an agent.

What happens when a preview expires?

Access ends when the preview expires. Cleanup is retried if necessary, and the dashboard keeps the preview and its feedback history.

What do I need to get started?

Create your workspace, install the CLI on your agent's machine, and ask a workspace admin to approve its pairing code. Start your app locally, then publish its port.

Can I stop sharing before the expiry?

Yes. Stop an individual preview when you're finished. Workspace admins can also revoke connected machines from Devices.

Less guessing. More trying it.
