Self-hosted Screenshots API for OpenPanel SiteManager

OpenPanel SiteManager displays a website screenshot for each website. These screenshots are generated using our hosted API.

Use Self-hosted Local Service​

When installing OpenPanel on your server, you can use the --screenshots=local flag to generate and host screenshots locally on your server instead.

This method is recommended for shared servers with a few TBs of storage and hundreds of websites.

OpenPanel will then install Playwright on your server to generate screenshots for all websites locally. Note that Playwright requires 1GB of disk space for the service, so it is not recommended for VPS servers.

Use Third-Party Screenshot APIs​

To use a third-party screenshot API, simply update the screenshots URL with the following command:

opencli config update screenshots "http://screenshots-api.openpanel.com/screenshot"

Replace http://screenshots-api.openpanel.com/screenshot with the URL of the third-party service, which will accept /<DOMAIN> and return an image.

Use Self-hosted Remote API​

If you have multiple OpenPanel servers and want to use your own screenshots API, you can designate one server to generate all the screenshots for domains hosted on other servers.

To do this, set up the Screenshots API service for OpenPanel on one server, add the domain to it, and then update the screenshots service on your OpenPanel servers to use the new instance:

opencli config update screenshots "http://your-screenshots-api.com:5000/screenshot"
