AssistivTunnel

AssistivTunnel is a small command line interface (CLI) that creates a secure connection between your computer and virtual machines or mobile devices running in Assistiv Labs, which enables you to test…

Any site or server running on localhost
Internal staging servers that may require VPN
Geofenced sites that only accept requests from certain countries or IPs

Installing

Download the CLI for your platform from your terminal or command prompt.

macOS

Open the Terminal app and copy/paste the below:

curl -L https://assistivlabs.com/cli/mac.zip -o mac.zip && \
  unzip mac.zip && \
  rm mac.zip && \
  ./AssistivTunnel --version && \
  echo 'Install complete!'

Note: if a bad CPU type in executable: ./AssistivTunnel error appears, please run: softwareupdate --install-rosetta

Windows

Open the PowerShell app and copy/paste the below:

$ProgressPreference = 'SilentlyContinue'
Invoke-WebRequest https://assistivlabs.com/cli/win-x64.zip -OutFile win.zip
Expand-Archive win.zip .
Remove-Item -Path win.zip
.\AssistivTunnel --version
Write-Host 'Install complete!'

Linux

Run the below command in your preferred terminal:

curl -L https://assistivlabs.com/cli/linux.zip -o linux.zip && \
  unzip linux.zip && \
  rm linux.zip && \
  ./AssistivTunnel --version && \
  echo 'Install complete!'

Start testing

Return to https://assistivlabs.com/dashboard and run the command containing your personal AssistivTunnel accessKey.

Your terminal/command prompt will contain output similar to below:

> ./AssistivTunnel --accessKey <YOUR_ACCESS_KEY>
Connecting...
✅ Connected successfully
You can now start testing from https://assistivlabs.com/dashboard.
Select the tunnel named "My-Computer" from the dropdown

You're now ready to test. Any URL that you can load locally will now work in Assistiv Labs. For example, paste https://localhost:3000 or https://staging.example.com into the remote browser.

FAQ

Is it secure?

Yes. AssistivTunnel uses TLS 1.2 end-to-end encryption for all communications. Traffic is not decrypted on our servers, it is only passed through. You can confirm this by visiting an HTTPS site in an Assistiv Labs browser and inspecting the connection certificate chain.

Only test devices in the Assistiv Labs cloud that you are actively testing can access your tunnel. Learn more about our security practices.

How does it work?

The AssistivTunnel CLI establishes a WSS (secure WebSocket) connection to our Relay server from your computer. When you start a test session from your Assistiv Labs dashboard and select an active tunnel, a new virtual machine or mobile device is provisioned and its network requests are routed through the Relay server over HTTPS. The network requests are then transmitted over WSS using a custom protocol to AssistivTunnel, which resolves the request and transmits the response over WSS back to the Relay.

When you end your test session, the test device and routing rule is deleted and all pending requests are cancelled.

A detailed whitepaper describing AssistivTunnel’s internals is available for security review upon request.

Can it be run centrally, from a DMZ or internal server?

Yes, if you only need to test internal websites with AssistivLabs (and not localhost) and would like to monitor the traffic moving through AssistivTunnel from a single access point, you can run AssistivTunnel from a DMZ or internal server. The tunnel can then be shared with everyone in your Assistiv Labs account.
