Connect to an instance on a different machine

You can use the Instance Bookmark feature to connect the LocalStack Web Application to a LocalStack instance running on a different machine.

To connect the Web Application with your running LocalStack instance, you need to ensure the endpoint URL’s server SSL certificate corresponds to the hostname/IP address of the URL. This is necessary when the endpoint URL is set as something like https://myhost:4566 or uses an IP address like Sites with an https://... URL must use HTTPS for requests, and the SSL certificate must match the hostname (e.g.,

To address this, consider setting up a local TCP proxy server that listens on and forwards all requests to the endpoint where your LocalStack instance runs. In the Web user interface, you can keep the default setting, Tools like simpleproxy or can help set this up.

Alternatively, you can direct to your target machine’s IP address by modifying the /etc/hosts file, which is useful if you’re using the LocalStack Web UI on a macOS or Linux-based machine.
