Product foundation,
bespoke result

Every CMS should make publishing easier, not create maintenance drag. Prosper CMS gives us a strong Rails-based foundation. We then design the editor experience, content model and front-end around your brand and your team.

FAQ

Custom CMS questions

How bespoke CMS compares with WordPress, Webflow and headless tools.

Why not just use WordPress?

WordPress works for many sites, but it often brings plugin maintenance, security patching, editor inconsistency and performance issues. Custom CMS removes that burden where the site justifies it.

Why not Webflow or Squarespace?

They work for simpler sites. Custom CMS makes sense when you need richer content models, workflows, integrations, multi-site management or long-term ownership.

How is this different from a headless CMS?

Headless platforms can be powerful, but they often need a separate frontend stack and charge per editor. Prosper CMS keeps content and rendering in one Rails app unless headless is genuinely needed.

Can you migrate our existing content?

Yes. We can migrate from WordPress, Webflow, Squarespace, Contentful, Sanity, Drupal and other systems with exports or APIs.

Will we own the site?

Yes. The site, content, data and deployment belong to you. Prosper can host and maintain the platform after launch.
