## AI 摘要

Show HN 板块投稿量在过去时期内增长三倍，但新项目在视觉呈现上呈现出显著的同质化趋势。分析指出，当前绝大多数展示页面采用了相似的"vibe-coded"设计风格，反映出AI辅助设计工具普及背景下的审美趋同现象。该观察来自2026年4月22日发布的分析文章，目前在Hacker News上获得109个点赞。

When browsing Hacker News, I noticed that many Show HN projects now have a generic sterile feeling that tells me they are purely AI-generated. Initially I couldn’t tell what it was exactly, so I wondered if we could automatically quantify this subjective feeling by scoring ~1400 Show HN pages for AI design patterns.

Claude Code has led to a large increase in Show HN projects. So much, that the moderators of HN had to restrict Show HN submissions for new accounts.

Here is how the Show HN submissions increased over the last few years:

Update: dang pointed out that the March 2026 dip correlates with the rollout of /showlim, the view newer accounts now see.

That should give us plenty of pages to score for AI design patterns.

AI design patterns

A designer recently told me that “colored left borders are almost as reliable a sign of AI-generated design as em-dashes for text”, so I started to notice them on many pages.

Then I asked some more designer friends what they think are common AI patterns. The answers can be roughly grouped into fonts, colors, layout quirks, and CSS patterns.

Fonts

Inter used for everything, but especially the centered hero headlines

LLM tend to use certain font combos like Space Grotesk, Instrument Serif and Geist

Serif italic for one accent word in an otherwise-Inter hero

Colors

“VibeCode Purple”

Perma dark mode with medium-grey body text and all-caps section labels

Barely passing body-text contrast in dark themes

Gradient everything

Large colored glows and colored box-shadows

Layout quirks

Centered hero set in a generic sans

Badge right above the hero H1

Colored borders on cards, on the top or left edge

Identical feature cards, each with an icon on top

Numbered “1, 2, 3” step sequences

Stat banner rows

Sidebar or nav with emoji icons

All-caps headings and section labels

CSS patterns

shadcn/ui

Glassmorphism

A few examples from the Show HN submissions:

Detecting AI design in Show HN submissions

Now we can try to systematically score for these patterns by going through ~1400 of the latest Show HN submissions and scoring their landing pages against the list above.

Here is the scoring method:

A headless browser loads each site (Playwright)

A small in-page script analyzes the DOM and reads computed styles

Every pattern is a deterministic CSS or DOM check. I intentionally do not take screenshots and let the LLM judge them.

This ultimately also leads to false positives, but my manual QA run verified it’s maybe 5-10%. If there is any interest in open sourcing the scoring code to replicate (and improve) the run or score your own site, let me know.

Results

A single pattern doesn’t necessarily make a site AI-generated, so I grouped them into three tiers based on how many of the 16 patterns they trigger.

I scored 1,590 Show HN submissions from the last few weeks:

Heavy (4+ patterns): 22% (347 sites)

Some (2-3 patterns): 32% (508 sites)

Clean (0-1 patterns): 46% (735 sites)

So a bit over half trip at least a couple of AI-design tells, and roughly a fifth lean on them heavily. The most common single tell is a permanent dark theme (34%), then gradient backgrounds (27%) and icon-card grids (22%).

Is this bad? Not really, just uninspired. After all, validating a business idea was never about fancy design, and before the AI era, everything looked like Bootstrap.

There is a difference between trying to craft your own design and just shipping with whatever defaults the LLMs output. And the same has been the case pre-LLM when using CSS/HTML templates.

I guess people will get back to crafting beautiful designs to stand out from the slop. On the other hand, I’m not sure how much design will still matter once AI agents are the primary users of the web.

This post is human-written, the scoring and analysis were AI-assisted.
