What is repo-cover gallery

repo-cover gallery is a social preview card generator for GitHub-style project promotion. It turns a repository name or project identity into a polished preview card that is meant to be shared as a social image, README hero, or link preview. The site describes the output as editorial, with four distinct moods and support for CJK-first typography.

Each card is delivered as a standalone HTML file, which makes the output easy to inspect, render, and host. The examples on the site are presented as live pages rather than static screenshots, and the page invites you to click through and view source.

Key features

• Four editorial moods are shown in the gallery, including styles labeled editorial, poster, blueprint, terminal, and banner variant in the source examples.
• CJK-first typography is built into the design approach, which makes the layout more suitable for Korean, Japanese, and Chinese text than a purely Latin-centric template.
• One self-contained HTML file per card keeps the asset bundle simple and portable.
• The gallery includes live examples for projects such as deepseek-ai/deepseek-harness, toss/frontend-fundamentals, zenn-dev/zenn-editor, ruanyf/weekly, and others.
• Output is checked by check_card.py, according to the site text.
• Rendering is done with the creator’s own Chrome, which suggests the visual result is tied to browser rendering rather than an abstract export pipeline.
• The source mentions an MIT license for the README hero card example, but the license for the whole project is otherwise not fully detailed on the harvested page.

How to use it

1. Open the gallery and choose a card style that matches your project tone, such as editorial, poster, blueprint, or terminal.
2. Review the live examples to see how the layout handles title length, avatar placement, and CJK text.
3. Click a card and view source if you want to understand the structure of the generated HTML.
4. If you are using the repo in your own workflow, the source points to a package-style command reference: npx skills add sjh9714/repo-cover.
5. Use the generated HTML file as a social preview asset, a README banner, or a project landing-page visual.

Because the app emphasizes generated output, the most useful workflow is to start from an existing mood and then adapt the content to your repository or project name.

Who it is for

repo-cover gallery is useful for developers who want better-looking project previews without building a design system from scratch. It fits especially well for:

• open source maintainers who need a strong README hero image
• indie hackers who want a polished social card for product launches
• teams sharing technical projects in multilingual contexts
• developers who prefer HTML-based assets they can inspect and version-control
• people who care about typography and want CJK-aware composition

It is also relevant for workflow-oriented users who want generated assets that can be checked in CI, since the site explicitly mentions validation with check_card.py.

What to know before you use it

The gallery shows the visual direction clearly, but the harvested text does not document full editing controls, pricing, or export formats beyond the self-contained HTML output. If you need exact implementation details, source code behavior, or license terms for a specific card, the official repository and the page source are better references than the gallery text alone.

This is also not a general-purpose design suite. It is focused on social preview cards and README-style cover graphics, so it will not replace a full branding tool, illustration editor, or multi-page layout app. The examples indicate that output is browser-rendered, which means final appearance can depend on Chrome behavior and any asset changes in the page.

For multilingual projects, the CJK-first approach is a strength, but it is still wise to verify line breaks, glyph coverage, and spacing in the final rendered HTML before publishing. If your use case involves official branding rules, product screenshots, or legal copy, use the authoritative source material rather than relying on the gallery alone.

In short, repo-cover gallery is best when you want a lightweight, inspectable way to create a social preview card with editorial styling and multilingual typography. If that matches your workflow, try the gallery and adapt the HTML output to your project.
