Build a Pinboard-style bookmark manager. Three-column layout: tag-chip sidebar on the left (sorted by use count, with active / archived view tabs), bookmark grid in the middle, add form on the right. Each bookmark card pulls /favicon.ico from the URL's host with a Globe-icon fallback. Add form auto-prefixes https:// when the user pastes a bare domain, defaults the title to the hostname, accepts comma-separated tags. Full-text search across title / URL / description / tags. localStorage persistence.

Create a 'read later' app like Pocket. Each saved page shows the title, hostname, estimated reading time (use 220wpm against character count as a proxy), and an /unread / /read / /archived state. Filter by state in the sidebar. Add a 'reader mode' toggle that opens the page in an iframe with a Reader-View-style typography overlay (max-w-prose, larger body type, dimmed chrome).

Design an Instapaper clone with offline reading. Save a URL, fetch its OpenGraph metadata on the server side (title, description, image, author, published date) and persist it as the bookmark's stored shape so the cards render properly even when the original page is later edited / removed. Sort by 'most-recently-added' or 'longest-read-time' or 'random'. Daily-digest email of unread items via Resend.

Build a research-notes link library. Each bookmark gets a notes field that supports markdown (render with marked + DOMPurify since multiple researchers can share the library). Per-bookmark backlinks: if note A links to bookmark B via [[B-title]] syntax, show 'mentioned in: A' on B's card. Per-tag RSS feed at /feed/[tag].xml so collaborators can subscribe.

よくある質問

How does this compare to Pocket / Pinboard / Raindrop / Instapaper?
Pocket is shutting down (Mozilla announced sunset in 2025), so 'Pocket alternative' is a real and active search. Pinboard is the closest functional match — both are tag-organized link libraries with archive workflow. The difference is ownership: this is YOUR app on YOUR subdomain that you can refine indefinitely. Raindrop and Instapaper are SaaS with paywalled features (more bookmarks, full-text-search, etc.); the FloopFloop-generated version has no row caps and the search-across-everything bar is free out of the box.
Where are my bookmarks stored?
The default template uses browser localStorage so the manager works instantly with no signup. Bookmarks live on whatever device you're typing on and don't sync across devices. Refine with 'add a Postgres backend so bookmarks sync across devices via a login' to move to server storage — the codegen scaffolds the schema, the API routes, and the sync logic in one round. The scanner blocks every external database (Supabase / Firebase / MongoDB) so the data stays on your own per-tenant Postgres schema.
Does it auto-fetch the title from the URL when I paste a link?
The default template lets you enter the title manually and defaults to the URL's hostname when you leave it blank — no server-side fetch is needed for the localStorage-only flow. For auto-title (the Pocket / Raindrop experience) refine with 'add a /api/extract-metadata route that fetches the URL on the server, parses the <title> and OpenGraph tags from the HTML, and returns them to the add form'. The codegen wires the server-side fetch + the meta parser + the form-prefill in one round. Honors a 5-second timeout and a 1MB body cap so a hostile URL can't burn server time.
Can I import my Pocket / Pinboard / Raindrop export?
Not in the default template. For import refine with 'add an /import page that accepts a Pocket .csv / Pinboard .json / Raindrop .html export, parses each row, and inserts it as a bookmark with the original timestamp + tag set preserved'. The Pocket CSV columns are stable (url, title, time_added, tags), Pinboard's JSON shape too — the codegen scaffolds the parser in a single round.
How are favicons fetched?
Each bookmark card requests `/favicon.ico` from the URL's host directly — no third-party service involved (no Google s2/favicons, no DuckDuckGo /ip3/, none of the privacy-leaky favicon proxies). When the request fails or the host doesn't serve a favicon, the card falls back to a Globe icon. The ~20% of sites without a conventional favicon path don't break; they just render with the fallback.
Can I share a bookmark list with someone?
Not in the localStorage default — bookmarks are per-device. For sharing refine with 'add a /share/[id] route that renders a read-only view of any tagged subset' OR 'add a public/private flag per bookmark and a /me page that lists my public bookmarks as a feed others can RSS-subscribe to'. The codegen wires the route + the privacy gate + the feed.xml in one round.
What's the biggest a single user's library can get?
localStorage caps at 5–10MB depending on browser. A bookmark row averages ~300 bytes (URL + title + a few tags + a short note) so the floor is roughly 15,000–30,000 bookmarks before quota pressure shows up. The search bar uses a single-pass substring filter across all rows on every keystroke — comfortably handles 5,000 bookmarks at the typing rate of a human; past that, refine with 'add a debounced search and a lightweight inverted index built from tags + words in titles' to keep it responsive.
