Websites and hosting decision
QR Tiger
A competent developer can replicate the core QR-generation and logo-overlay features in about a week and run it cheaply; QR Tiger's main durable advantage shown is brand recognition only, which is not a technical moat.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- User supplies payload (URL/text), optionally uploads a small logo and selects colors; system generates a downloadable QR (PNG/SVG) with the logo and styling.
What it still won’t have
- SLA/uptime and global CDN edge distribution
- Brand polish, dashboards, and polished UX flows
- Enterprise features (team management, usage billing, bulk API limits)
- Analytics and built-in customer support
What remains hard
- Brand trust

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal QR-code-as-a-service using Node.js (Express), a Postgres DB, and a small object store (local filesystem or S3). Core features: HTTP form + JSON API to accept payload (URL/text), color options, and a logo upload; server-side QR generation (PNG and SVG) using an open-source QR library; compose and center a scaled logo into the QR safely (size checks, raster/vector outputs); return a preview and downloadable file; store metadata (payload, filename, timestamp) in Postgres. Out of scope: multi-tenant billing, bulk import UI, analytics dashboards, and mobile apps. Require input validation, virus-scan/size limits on uploads, error handling, and automated tests for generation, upload, and API endpoints.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 3 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score90
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
