Static QR codes are free, unlimited, watermark-free and need no account. Dynamic ones stay editable after you've printed them, so a menu or flyer can be repointed without a reprint, and every scan is tracked by time, device and rough location. 37 content types, PNG/SVG export, and a documented HTTP API. There's also an AI mode that generates a real photograph and prints your code onto a surface in it — the code is a genuine QR, so it still scans.
Goodreads hasn't meaningfully changed since Amazon bought it. Letturia is the alternative: shelves, streaks, stats and a yearly Wrapped, plus book clubs with real reading schedules, polls and discussion guides, a map of independent bookshops, and an AI librarian for what to read next. Reviews are spoiler-safe. Public-domain classics read in-app. Import from Goodreads in minutes and export whenever you like — free on every plan, permanently. No ads, no Amazon, and 22 languages.
