When Keystone was first built, it ran a single theme across all sites.
As more sites from across the portfolio joined, the requirements from a commercial and UX perspective grew beyond the original theme’s capabilities. A new theme called ‘Keystone Premium’ was created as part of the migration for Marie Claire.
More recently, Keystone Premium was completely refactored into a standalone theme called Keystone Simba. The original Keystone theme is known as Keystone Classic to distinguish it from Simba.
The lists below are true as of June 5th, 2019. Please note that some sites are not on Keystone whatsoever, and they’re presented at the bottom of this directory for reference.
