Export is the product

Most prototyping tools want to host your prototype. The artifact lives on their domain, inside their iframe, behind their badge — and the moment you stop paying, it stops existing. That model makes sense for the tool. It makes no sense for a growth team.

Growthtyping takes the opposite position: you own the output. Every prototype exports as pure, dependency-free HTML/CSS — a single file you can open, email, or drop anywhere — plus the raw React source files for engineering. Copy a file, copy them all, or download the zip. No iframe lock-in, no watermark, no runtime dependency on us.

A growth prototype has two audiences, and they want different things. Stakeholders want something clickable they can react to in a meeting — that is the HTML export, self-contained and portable. Engineers want a starting point they can actually build from — that is the raw React output, real components they can read, diff, and adapt instead of reverse-engineering a screenshot.

The moment a prototype gets a yes, its job changes from persuasion to handoff. If the artifact only lives inside our product, the handoff means re-work. If it exports as real files, the handoff is the files.

This is also a deliberate competitive position. Tools whose business model depends on hosting your output structurally cannot give it away — hosting is their retention. We can, because our value sits earlier in the loop: brand ingestion, the pattern library, the compiler that turns an experiment idea into an on-brand render. The export is the finish line, not the leash.

It also keeps us honest. If the exported artifact is not good enough to stand on its own — outside our preview, without our chrome — then the prototype was not good enough, full stop. Owning the output means every render has to survive contact with your codebase and your stakeholders, not just look good in our UI.

Prototype an experiment, show the HTML file in the prioritization meeting, and when it gets a yes, hand the React files to engineering. If you cancel tomorrow, every artifact you exported keeps working exactly as it does today. That is the whole policy: the ideas are cheap, the render is metered, and the output is yours.
