Features
Pantheon is a combination of web development tools in the cloud and web hosting and management services. It is based in the cloud, and is free until deployment. Developers have a choice between Drupal and WordPress and installation of profiles like Open Atrium, or custom upstreams with user-specified configuration. Data can be imported onto Pantheon automatically from existing Drupal-based websites. Its container-based architecture allows for multiple development environments of a single website.

Hosting of hate group websites
In April 2023, Pantheon was criticized by open source developers for hosting the websites of Alliance Defending Freedom (ADF) and the Federation for American Immigration Reform (FAIR). Both organizations have been designated as hate groups by the Southern Poverty Law Center for the ADF's anti-LGBT stance and FAIR having "ties to white supremacist groups and eugenicists". Koenig confirmed in a statement that Pantheon would continue to host the organizations' websites.
