Solo Founder Builds Demo Video with Claude Code and Remotion

Practical Approach to Demo Creation
A solo founder delayed launching their product, SiteCheck, for months because they couldn't afford demo videos. Freelancers quoted $500 for basic work and requested design assets like Figma files and brand guidelines that didn't exist. The developer, lacking design skills, found the traditional design process foreign and postponed the launch.
Technical Implementation
Using Claude Code with Remotion (videos as React components), the developer structured the video into reusable components. Claude helped with:
- Breaking the video into reusable components
- Tweaking animations and timing quickly
- Iterating on layouts without needing design tools
The first version was rough, but since everything was code-based, improvements were made through quick edits to font sizes, spacing, and animation timing instead of full re-exports. The developer added a voiceover using ElevenLabs, background audio, and rendered everything directly from the terminal.
Product Context
SiteCheck is a tool that audits a website's UX in approximately 30 seconds and generates a report with suggested fixes ranked by impact. The product was already functional with positive feedback from early users, but lacked visual demonstration materials.
The developer notes the result isn't perfect but served to unblock the launch process. The project is free to try and planned for public launch soon.
