What it is
81-web is a Japanese website reference archive with a filterable index and view controls. It offers 5,453 sites at review. Search can narrow by site type, industry, color, font, tag, credited agency or studio, and date. Results can be switched between desktop and mobile preview and between cover and masonry layouts.
When to open it
- When you want to compare many Japanese sites by their visual palette, type or credited studio.
- When a design question depends on the difference between a desktop and phone composition, or between a regular card grid and a masonry scan.
- When you want an index with explicit filter and display controls before opening a source website.
Most useful
- Use the main archive to combine the Keyword, Type, Category, Color, Font, Tag, Agency & Studio and Date controls. The result count and view controls remain visible above the cards.
- Switch between Desktop and Mobile and between Cover and Masonry views on the page. These controls change how the same set of examples is presented, making it easy to scan either full screenshots or a staggered grid.
- The QuSS Quantum Science School site was inspected at review. Its hero uses an oversized high-contrast serif wordmark and Japanese headline, a sparse pale background and a compact horizontal navigation; the news ticker overlaps the lower edge. Use it as a live example of editorial scale and asymmetric placement.
- Open a selected site's own URL to verify its current mobile behavior and interaction; the archive is an index, not a substitute for the original.
Using it with agents
No MCP, API, llms.txt or agent export was visible on the reviewed page. An agent can use the browser's visible filters and preview controls, then follow a card to its source. Record which viewport and display mode you inspected so a cover preview is not mistaken for full-page behavior.
Watch out for
- Many labels and categories are Japanese, and the homepage includes advertising placements among the results.
- The archive's count is a point-in-time figure and may change; it showed 5,453 sites at review.
- No general reuse licence was stated for screenshots or indexed websites. Use them as visual references only.
Reusable ideas
- Keep search facets for visual properties, source category and maker separate so users can combine them without conflating what a site looks like with what it is about.
- Let users compare the same archive in mobile and desktop previews, and choose between cover and masonry scanning.
- Show the number of matching results close to the filters so narrowing the archive has immediate feedback.
