Klaser Cards is a browser-based tool that transforms your media wishlists and collections into printable 63 × 88 mm game cards—the same dimensions as standard board game cards. The name derives from the Polish word "klaser," meaning a collector's album for things you love, want to own, or want to experience next. Rather than scrolling through yet another digital database when deciding what to watch or play tonight, Klaser lets you shuffle physical cards and let randomness pick your fate. If you're not feeling what you drew, there's always the mulligan option—because nobody has to know.

How It Works

The process involves four straightforward steps: first, type a title into the input field; second, hit fetch and watch as Klaser automatically pulls data from public APIs including BGG (BoardGameGeek), OpenLibrary, OMDb (Open Movie Database), Comic Vine, and RAWG. Third, customize which five pieces of information appear on each card—you can choose between short data fields or longer content blocks. Fourth, print up to nine cards per A4 page with optional backs, and there's a built-in black-and-white filter for saving ink. The tradeoff? You're still handling the cutting and sleeving yourself—Klaser hasn't solved that part yet.

Data Sources and Privacy

One notable aspect of Klaser's architecture is its commitment to public APIs rather than web scraping. All data fetching happens through official endpoints from BGG, OpenLibrary, OMDb, Comic Vine, and RAWG—no page scraping involved. After pulling information, users can edit any field before printing. There's also no account requirement; finished cards remain entirely in your browser with no cloud sync or server storage to worry about. Available data fields vary by media type: movies include cinema poster, year, runtime, director, IMDb rating, and Metacritic score; books pull cover art, author, pages, genre, publisher, and ISBN; tabletop games surface designer, player count, playtime, BGG rating, weight, and year.

Supported Media Types

Klaser currently handles movies, TV series, novels, comics, tabletop games, and video games. For each category, the tool fetches relevant metadata automatically: OMDb covers cinema content while Comic Vine handles comic book data. Board game enthusiasts get access to BGG's extensive database of designer credits, weight ratings, and community rankings. RAWG provides coverage for video games across multiple platforms with Metacritic scores included. The system supports filling five customizable slots per card, allowing collectors to prioritize the information that matters most—whether that's director credits for movies or player count ranges for board games.

Key Takeaways

  • Nine cards fit on a single A4 page, printed either with backs or in ink-saving monochrome mode
  • All data fetching uses public APIs—no scraping—editable before printing
  • No accounts required; your collection stays local in your browser
  • Four-step workflow: type title → auto-fill → customize → print and cut

The Bottom Line

Klaser Cards occupies an interesting niche at the intersection of analog aesthetics and digital convenience. For collectors who want something tangible without abandoning their curated databases, it's a clever workaround for decision paralysis—shuffle the deck, pick your fate, and maybe finally watch that movie that's been sitting in your wishlist since 2022. The lack of account requirements is a refreshing privacy win, even if it means you're responsible for backing up your card data yourself.
