SleekPixel for Show HN cards
SleekPixel reads the HN submission URL, project title, repo URL, and license from a single Show HN post and renders a Twitter-card share image. The template uses an understated style that fits HN's culture - because looking too polished hurts you on Show HN.

Show HN submissions live or die by their fit with HN's culture
Show HN is its own subgenre on Hacker News with its own conventions. The successful submissions look like developer artifacts, not marketing launches. They name the project, the repo, and the license; they show the author's hand. The least successful submissions look like venture-funded launches, which the audience dismisses on sight. The share that travels with the submission is part of that signal.
SleekPixel reads the Show HN post's hn_url, project_title, repo_url, and license fields, then renders a 1200x675 card. The template uses a muted amber accent, monospace type, and minimal supporting copy. The full project description stays in the post body.
Run subsequent Show HN submissions (major releases, related projects) from the same template. The visual rhythm signals to the audience that the maker understands the platform, which is itself a credibility marker on Show HN.

Features
What SleekPixel gives you for Show HN card
HN-native design
The template uses monospace type and muted accents - the visual language of the platform's audience. Polished marketing graphics get downvoted; understated technical artifacts get upvoted.
Repo-first
The repo URL is visible. Show HN audiences click through to GitHub before they upvote, and a visible repo signals the project is real and inspectable.
License clear
The license (MIT, Apache 2.0, GPL, etc.) is on the card. Show HN audiences care about license because it affects whether they can adopt the project.
Use cases
Where Show HN cards earn organic upvotes
Maker tweet at submission time
Tweet the card the moment the submission goes live. Developer audiences on X retweet with the same image, which extends reach without triggering HN's coordination penalties.
Developer-community DMs
Forward the card to peers in technical Discord and Slack communities. The image fits the aesthetic of those audiences, which encourages organic sharing.
Project README share
Embed the card at the top of the project's README. New visitors discovering the repo see the Show HN context, which lifts engagement from passing GitHub traffic.
The bigger picture
Why Show HN cards need cultural fit, not polish
Show HN is a niche within a niche. Audiences are mostly developers, mostly engineers who build things in their spare time, and mostly skeptical of anything that looks venture-funded or marketing-led. A Show HN submission with a polished marketing card will get downvoted, flagged, or quietly ignored.
A Show HN submission with a restrained, monospace-typed, repo-visible card will get upvoted and commented on by the same audience. The difference is entirely cultural. SleekPixel's Show HN template is designed to match the platform's aesthetic: muted colors, monospace type, license visible, repo URL clear.
The maker comes across as someone who built something with their own hands and is sharing it. That signal is what earns upvotes from Show HN's audience. Beyond the design, the card carries real operational benefits.
The repo URL is visible at thumbnail size, which means anyone scrolling through Twitter who is interested can click through immediately. The license is visible, which removes a friction point for engineers who care about adoption. The combined effect is a submission that fits the platform, which is the entire game.
Hundreds of early adopters can come from a single well-placed Show HN, and the card is one of the levers that makes that outcome reproducible.
Questions
Common questions about SleekPixel for Show HN card
The HN launch card is for general HN submissions (product launches, announcements). The Show HN card is specifically for Show HN submissions, which have their own conventions and audience expectations.
The repo URL is visible on the card as text. Linking directly is what the host post page does; the card itself is a PNG and cannot embed clickable links.
Yes, to Show HN audiences. Engineers consider license before they upvote because it affects whether they can use the project. Surfacing it removes a friction point.
Optional. A small region can render 'stars: 247' or similar from a star_count field. Most teams skip this because numbers fluctuate and look bad if they regress.
No. Show HN's algorithm ranks on upvote velocity and comment activity. The card affects what supporters see on Twitter when deciding whether to upvote.
A small mark is fine. A large branded logo tips toward marketing and works against you. Most successful Show HN cards use the project name in monospace as the main visual element.
Yes, but include the licensing model on the card (e.g. 'source-available', 'fair-source', 'commercial'). Show HN audiences will downvote projects that obscure their license.
Helpful but not required. Many makers use the same SleekPixel render as the README's hero image, which creates visual continuity between the Show HN submission and the repo page.
