Great websites. Easier to manage.

RealMosaic is a managed CMS for web designers and their clients. Create the website you want, with forms, SEO controls and performance tools built in. We look after hosting and platform updates, with direct support from the people who build it.

You can handle content for your clients, or give them accounts to make everyday updates.

More time for client work.

Build and improve your clients' websites while we look after the CMS, hosting and platform updates. Forms, SEO controls and everyday content tools are already part of the platform.

The tools your sites need.

Built-in forms, stored submissions, search and social metadata, redirects and publishing tools give each website a useful starting point. Fewer separate add-ons to source and maintain.

See what we look after

Multiple sites. The right access.

Manage multiple websites from one CMS, with user permissions built in. Handle content for clients or give them accounts with access to the sites and tools they need.

Explore sites and user access

Your design. Familiar web tools.

Use your favourite tools to explore ideas and develop the design. Build with HTML, CSS and JavaScript, then connect the website to RealMosaic's content through layouts and reusable partials.

Headless by design, with website delivery already connected. Rendering, image processing, caching and asset delivery work together behind the scenes, while your agency controls the front end.

Compare theme changes with saved versions and restore earlier files. Clients can focus on content within the editing areas and permissions you prepare.

Performance, built into the platform.

Right-sized images, leaner assets and caching work together in the managed delivery layer. Give client websites a considered performance foundation, with the original files and controls still in your hands.

Smaller images. Less manual work.

Whittle, our built-in image engine, creates the sizes, crops and web-ready formats your layouts need from the original upload. Generated versions are cached for reuse.

Lighter pages. Originals kept.

Performance Mode can serve reduced CSS while keeping the source files intact. Load page-specific styles and scripts where they belong, and switch back to original CSS when you need to.

The everyday details, covered.

Caching, search and social metadata, redirects and sitemap tools are part of the platform. Give every project a consistent foundation to build on.
