Beautiful, scannable QR codes from your browser
Why we built Wrasse: privacy-first, multilingual QR codes that beat the incumbent Japanese tools without sending a single URL to a server.
The problem with most QR generators
Most QR code tools you'll find on the first page of search results are either dated freeware that hasn't been touched in years, or paid platforms hiding basic features behind a sign-up wall. Almost every one of them sends the URL you want to encode to their server first. The QR data is the URL itself β a server endpoint that takes your URL and hands back a generated image is unnecessary middleware that creates a privacy liability where none needs to exist.
Why client-side static QR matters
A static QR code's data is whatever you put in it. There is no transformation between input and output that requires a server: the QR module pattern is computed deterministically from the payload string. Wrasse generates every free static QR entirely in your browser. Your URL, contact, password, or wallet address never reaches our servers. We enforce this architecturally β a CI test scans the static QR pipeline for any import of server-only code and fails the build if one slips in. The privacy claim is testable, not a marketing promise.
Multilingual from day one
Wrasse ships in Japanese, English, Traditional Chinese, and Korean from launch. Every UI string, every error message, every input-type landing page is hand-translated. Simplified Chinese is intentionally absent β by policy, zh-CN browsers are served Traditional Chinese rather than fall back to English. This makes Wrasse the first QR generator targeting the Japanese market that respects Hong Kong / Taiwan readers without compromising on the rest of the CJK reach.
What's coming next
Phase 2 introduces dynamic QR codes β short links you can repoint after the QR is printed β with privacy-aligned analytics that capture only country and device class, never IP or User-Agent. Phase 3 adds AI Art QR codes powered by Cloudflare Workers AI, paid-only by design so the free tier stays a clean static QR experience. Phase 4 brings bulk generation, a built-in scanner, Smart Landing Pages for Wi-Fi and vCard share, and a public REST API. Each phase ships independently; everything runs on Cloudflare's edge.
