GitHub Marketplace feature card preview before brand refresh
Treat the feature card preview as part of brand work before launch, because GitHub can feature the app on the Marketplace homepage and the card has to stand out in one glance.
Why this can grow a startup
A lot of developer listings get brand work backwards. Teams polish the website first and leave the marketplace card looking like a default asset export. GitHub gives featured apps a large card at the top of the Marketplace homepage and lets the draft listing preview the logo, badge color, and feature card as you edit. That preview is useful because the card is not just decoration. It is the public face of the app inside GitHub's own shelf. A card with a clear mark, readable text, and a distinct background gives the listing a chance to be remembered when the homepage rotates.
Company example
GitHub's listing-description guide says featured apps can appear in one of four slots at the top of the Marketplace homepage, shows a live preview while you upload brand assets, and recommends a patterned or textured background image sized 965 by 482 pixels for the feature card.
Source and metric
Source: GitHub Docs: Writing a listing description for your app
GitHub feature cards use a 965 x 482 pixel background image and can appear in one of four featured homepage slots.
When to use it
Use this when Marketplaces, Brand, Conversion is relevant to brand system, homepage feature, visual identity and you can run a bounded test with a low budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
