I needed a solid solution to provide clients with a brand center. This solution delivers the basics. Lots of customization options, including custom domains, custom logos, etc for each brand space. Besides logos, fonts, colors, you can add any type of section (called collections) including text styled with markup to provide the client with usage instructions, or other information like brand personality, tone, etc.

Had a small issue with my account being activated in the free plan instead of the pro plan, but their support responded and immediately corrected the issue.
