About
About Convertfast UI
The MIT-licensed tool provides responsive design out of the box, dark and light mode support, customizable components and sections, with planned SEO structured data support. Built with TypeScript (94.5% of codebase), Tailwind CSS, and Next.js, Convertfast UI offers CLI commands for rapid landing page development including 'npx convertfast-ui@latest init' for initialization, page creation, and section addition workflows.
The tool emphasizes ease of use through command-line workflows that generate production-ready landing page code quickly. Perfect for marketing campaigns requiring quick landing pages, SaaS product launches, portfolio sites, promotional pages, or any project needing professional landing pages without design work from scratch, Convertfast UI accelerates landing page development while maintaining code quality, responsiveness, and customization capabilities through shadcn-ui's component system and Tailwind's utility-first approach.

FAQ
Frequently asked questions
Everything you need to know before you ship with Convertfast UI.
Convertfast UI is a CLI tool for creating beautiful, customizable landing pages with prebuilt code blocks based on shadcn-ui and Tailwind CSS. It is an open source template in the shadcn.io collection of 215.
Convertfast UI is made by Observedobserver, an independent developer; shadcn.io lists it but did not make it. Observedobserver has 1 template in the collection, and the author's page lists them.
The listing tags Convertfast UI with Tailwind and Landing Page. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.
Yes. The Convertfast UI page embeds its live demo from ui.convertfa.st, and links to it so you can open the real deployment before you clone.
The Convertfast UI listing was last updated on October 8, 2025. That date is the listing's, not the repository's: check the repository's commits for recent activity.
Clone the repository (git clone https://github.com/ObservedObserver/convertfast-ui), then follow the README. The Convertfast UI page shows the usual steps and a terminal block with the commands to copy.
Install dependencies with npm install or pnpm install, then run npm run dev. The README in the Convertfast UI repository says which package manager and environment variables it needs.
No. Convertfast UI is cloned from its own GitHub repository, so shadcn.io isn't involved. Browsing the page and its live demo need no account either; Pro adds the premium templates, the blocks and the MCP server.
Follow the deployment notes in the Convertfast UI README: the right host depends on its framework and any services it needs. The page's categories show what it is built for.
The Convertfast UI listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/ObservedObserver/convertfast-ui), and ask the author if there isn't one.
That depends on Convertfast UI's license in its repository, which shadcn.io does not set. Read the LICENSE file before you use it in a client or paid project, and ask the author if it is unclear.
Attribution follows Convertfast UI's license. Many permissive licenses ask you to keep the copyright notice and license text in your copy; its LICENSE file says exactly what.
No. The Pro license covers shadcn.io's own Pro code, blocks and premium templates. Convertfast UI is the author's project, under the terms in its repository.
Observedobserver supports Convertfast UI, through its GitHub repository: read the docs, open an issue or look for discussions. shadcn.io does not maintain it.
Yes. Once you clone it, Convertfast UI is your own code: change the theme, add pages and connect your backend. It uses shadcn/ui, so you can also add more components the same way.
Yes. Components are free with a free account and the blocks are in Pro; both are copied into your project with the shadcn CLI. Check that Convertfast UI uses Tailwind CSS and the shadcn/ui setup (a components.json) before you add them, and pick the base library your project already uses.
Yes, with Pro. The shadcn.io MCP server's search_templates tool finds templates by what they are, and returns each one's repository and live demo, so your editor can set up Convertfast UI for you. Your files stay on your machine.
The collection has 4 other open source Landing Page templates like Convertfast UI, shown at the foot of its page with the ones sharing most categories first. All of them are at /template/category/landing-page.
Observedobserver has no other templates in the collection.
Yes. The 14 premium templates (Solaris, Reframe Labs, Spherule and Max and more) are built by shadcn.io and come with every Pro plan, if you want maintained code with a design file.
