Design and diagrams decision
Draftly
A single developer can produce a usable prompt→multi-screen HTML generator and export workflow, but reproducing Draftly's polished hosted product, gallery, and operational polish is multi-week work and would lack vendor tooling and community features.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Draftly alternatives, with the arithmetic →
What a replacement has to do
- Accept a plain-English prompt, plan app screens and design system, generate multi-screen HTML/Tailwind UI, allow targeted edits and preview, export screens and design system.
What it still won’t have
- Hosted workspace with multi-project account management and team features
- Polished UX, onboarding, and iterative prompt/product tuning from product usage
- Public showcase and community-generated inspiration gallery
- Operational reliability and scaling optimizations
- Customer support, billing, and legal/compliance work handled by vendor
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Draftly does not publish a price we could read, so there is nothing to compare against. What building costs is below.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal AI UI generator web app using Next.js (React), Tailwind CSS, a small Postgres or SQLite store, and an LLM API (OpenAI-compatible). Core features in scope: (1) prompt + guided-question intake UI, (2) an LLM orchestration layer that produces an app plan and per-screen JSON specs, (3) a template-based renderer producing responsive Tailwind HTML for each spec, (4) a preview/editor allowing simple edits that re-render the screen, and (5) an export endpoint that bundles selected screens and a design-system Markdown file into a ZIP. Out of scope: multi-user billing, large-scale collaboration, public showcase, advanced image generation. Include error handling, unit tests for rendering logic, CI to run tests, and basic Docker-based deployment instructions.

- 5 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score64
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
