Riftarc is an independent, unofficial companion for Riftbound players, designed to make managing cards and preparing for game night easier. Its free website and mobile apps help players track collections, organize exact card printings in binders, and keep tabs on sealed products. Camera-assisted scanning is available on supported devices, with scanning processed locally where supported; the mobile app also offers offline access to catalogues, collections, decks, and matches.

Players can search card printings, rules, errata, ban status, and prices, then build or import decks, check legality and card ownership, and export missing cards as printable PDFs. Riftarc also supports proxy creation, collection sharing, and tools for comparing trades by exact printing, market, currency, and cash difference. During matches, players can track scores and turn priority. Price comparisons include marketplaces such as TCGplayer, Cardmarket, CardTrader, and eBay, with price history and alerts also available. Riftarc states that its tools are free without subscriptions or usage limits, and that its signed-in web app is ad-free.
