How does the platform differ from standard HubSpot CMS themes?
Traditional themes provide a locked set of pre-coded templates and layout blocks. Flexbox Pro is a dynamic generative developer tool: upload design layouts, paste copy briefs, or run a step-by-step chat session to build custom modules for unique requirements. It eliminates structural limitations, letting agencies build custom sites without compromising design or code quality.
What structural files are generated when I download a module?
Every exported package contains 100% native, HubSpot-compatible source code compiled to the latest development standard: a custom editing interface schema (fields.json), a rendering template wrapper (module.html), scoped non-leaking layouts (module.css), and lightweight behavior scripts (module.js). All files are fully accessible and editable in HubSpot Design Manager or local code tools.
