RepoTrailer v0.1.0

RepoTrailer v0.1.0

RepoTrailer turns a GitHub repository into README-ready launch assets: social
card, browser preview, release copy, JSON storyboard, editable HyperFrames
composition, and optional MP4.

It is built for maintainers who already have a useful project but need a faster
way to show why it matters.

Try it

Generate a static launch kit from any local repository:

npx --yes --package=github:howong217-ui/repotrailer repotrailer . --no-video

Generate from a public GitHub repository:

npx --yes --package=github:howong217-ui/repotrailer repotrailer owner/repo --no-video

Omit --no-video to render the optional HyperFrames MP4 when Chrome/Chromium
and FFmpeg are available.

What is included

• index.html: responsive storyboard preview
• social-card.svg: 1200x630 launch/social card
• launch-copy.md: short post and Show HN draft
• repotrailer.json: auditable source facts and scene timings
• hyperframes/: editable video composition
• trailer.mp4: optional rendered video when video mode is enabled

Examples

The repository includes generated cards for:

• sindresorhus/ky
• Textualize/rich
• BurntSushi/ripgrep

Design rules

• No hosted service or API key required for the default static path.
• Claims come from README, package metadata, source files, and git history.
• It does not invent stars, downloads, benchmarks, or adoption claims.
• Local repositories stay local; public GitHub URLs are cloned to a temporary
  directory.

Feedback requested

The most useful feedback for this first release:

1. Does the generated story feel accurate for your repository?
2. Did the first command work on your machine?
3. Which output would you actually share: preview, card, copy, or video?
