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
- Internal staging servers that may require VPN
- Geofenced sites that only accept requests from certain countries or IPs
- Download the CLI for your platform from your terminal/command prompt:# MacOScurl -L https://assistivlabs.com/cli/mac.zip -o mac.zip && unzip mac.zip# Windowspowershell.exe "$ProgressPreference='SilentlyContinue'; Invoke-WebRequest https://assistivlabs.com/cli/win.zip -OutFile win.zip; Expand-Archive win.zip ."# Linuxcurl -L https://assistivlabs.com/cli/linux.zip -o linux.zip && unzip linux.zip
- Copy your personal AssistivTunnel access key from https://assistivlabs.com/settings
- From a terminal or command prompt, run# MacOS / Linux syntax./AssistivTunnel --accessKey <PASTE KEY HERE># Windows syntax.\AssistivTunnel.exe --accessKey <PASTE KEY HERE>
The CLI will output something like:
Connecting...✅ Connected successfullyYou 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://staging.example.com into the remote browser.

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?
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.
