Test staging and internal tools behind your firewall

The product that matters most is often on a private URL: staging, an admin panel, an intranet. A hosted browser cannot reach it. A worker runs the browser on your side of the firewall and dials out, so actors test private URLs with no inbound firewall changes.

How it works

Captures on this page are from a workspace testing Parlour, a demo app simulating a restaurant booking flow.

  1. 01

    Choose where the browser runs

    The Mac app turns your own Mac into a worker on every plan. On Enterprise, run a worker as a Docker container or with the CLI.

    1. Worker on your Mac or server
    2. Out through your firewall
    3. Stunt Double
    The worker dials out to Stunt Double, so nothing opens inbound.
  2. 02

    Set what it can reach

    A domain allowlist sets which hosts the worker can open, so an actor stays on the systems you meant it to test.

    1. Worker
    2. Domain allowlist
    3. staging.yourcompany.com
    The allowlist sets which hosts the worker can open.
  3. 03

    Run checklists as usual

    Actors, checklists and interviews work the same way. The only difference is where the browser sits.

    A checklist and its run history, one row per run.

The requirements you would write

Plain language, one per line. An actor checks each one in a real browser.

  1. 01A support agent can find a customer by email address
  2. 02An export from the admin panel produces a file
  3. 03A new starter can find the leave policy on the intranet
  4. 04Staging sign-in works with the test account

What comes back

  • 01

    Each check passed or failed, with the screenshot and the reasoning behind it

  • 02

    A recording of the whole session, step by step

  • 03

    Insights for anything a check did not ask about

Where it stops

A worker reaches only what its network and its allowlist let it reach, so a flow that crosses into a system it cannot see stops there.

Questions people ask

Do I need to open firewall ports?

No. The worker dials out to Stunt Double, so there are no inbound firewall changes.

Which plans include workers?

The Mac app works as a worker on every plan. Docker and dedicated workers are part of Enterprise.
