Extend your Confluence use cases with a powerful, secure HTML macro. Unlike other solutions, Mosaic automatically sanitises code to block unsafe scripts, while enabling structured editing and admin-controlled JavaScript for better governance. This gives teams full flexibility to create dynamic content without compromising security.

Why use the HTML macro:

Build custom layouts with HTML, CSS, and JavaScript for tailored use cases.
Add interactive elements to enhance static Confluence pages.
Control structure, spacing, and design to create website-like experiences.
Use pre-built code snippets for consistent, polished content without starting from scratch.
Import existing HTML, CSS, and JavaScript files easily—ideal for migrations.

Security certified: ISO 27001 certified for enterprise-grade security and built on Atlassian Forge.
