README banners are the second hero of an open-source project
The first thing a developer sees on a GitHub repo is the README, and the first thing they see in the README is the banner. A real README banner with the project name, the tagline, and the version reads as a project that takes itself seriously. A blank README that drops straight into a list of badges reads as a side project. Done manually, the banner is a Figma export uploaded to the repo's assets folder, and it ages out the moment the version bumps because nobody reopens the file.
SleekPixel makes the README banner a render of a project post in WordPress. The template is 1280 by 640, in HTML and CSS, with slots for the project name, the tagline, the version, and any custom field. README files reference the rendered file by URL, so a version bump in the project post updates the banner across every README that references the URL. An org with twenty libraries shares the template family, so every README banner reads as one team without per-repo design.
For repos that prefer to commit the file rather than hot-link, SleekPixel exposes a download button in the WordPress editor sidebar. The PNG is named after the project, ready to drop into the assets folder and reference relatively from the README.

Comparison
Manual README banners versus SleekPixel
Manual / Figma / no banner
- Most repos skip the banner because Figma rounds are not worth the time
- Banners that exist still show v0.3 long after the project shipped v2
- Twenty repos under one org each get a banner in a different style
- Tagline rewrites in the project post never propagate to the banner
- Designers refuse to redo the file every time a version bumps

Features
What SleekPixel gives you for GitHub README banners
Per-project render
Each project post produces its own 1280 by 640 README banner with the right project name, tagline, and version.
Hot-linkable
READMEs reference the rendered file by URL, so a version bump in the project post propagates to every README pointing at it.
Sidebar download
Prefer to commit the banner? Click download in the editor sidebar and place the PNG in the repo's assets folder.
Use cases
Where README banners shape the project read
Library suite
An org publishing a suite of libraries renders a banner per library from the same template, with each library's name and version.
Version bumps
Major or minor version bumps update the banner version on save without a Figma round trip.
Docs site mirror
Docs sites that mirror project posts share the same banner between the docs hero and the GitHub README.
The bigger picture
Why README banners decide the first impression on GitHub
Open source has a small attention budget. A developer scanning a list of starred repos or a search result clicks through, looks at the README hero, and decides in seconds. A real banner with the project, the tagline, and the version anchors that decision and earns the next thirty seconds of reading.
A missing banner leaks attention. Manually maintained banners survive the first launch and then go stale on the first version bump because the file does not auto-update. SleekPixel makes the banner a render of the project post, so version bumps and tagline rewrites propagate without a Figma round trip.
An org of twenty libraries reads as one team because every README banner came out of the same template. Hot-linking means a single source of truth between the docs site and the GitHub README, with the project post deciding what the banner says.
