Common questions
Is FreeQrly safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 20 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

FreeQrly
Free QR codes in your browser. Static codes never expire.
freeqrly.com · Developers · Barcode generator · Scanner
FreeQrly is a free QR code generator built on a simple idea: the tool should live in your browser, not on somebody's server. No sign-up walls, no watermarks, no subscriptions — and static codes that can never expire.
Features
Generate
- 17 code types including batch mode: URL, text, WiFi, vCard, email, SMS, phone, location, calendar events, Bitcoin, coupons, App Store links, reviews, audio, Google Forms, menus
- Batch generation — paste a list or drop a spreadsheet, download everything as one ZIP
- Free dynamic codes (20 on a free sign-in): edit the destination after printing, with scan statistics by day, country, city and device
- Free barcode generator: Code 128, EAN-13, UPC-A, Code 39, ITF-14
- Built-in scanner: decode from your camera or an uploaded image, fully on-device
Customize
- Your logo in the centre (6 brand presets or your own upload) — error correction rises automatically so it still scans
- Colours, dot shapes, transparent background, rounded / text frames
- Print-ready PNG (up to 4096 px) and SVG export
Private by design
- Static codes are generated 100% client-side — links, contacts and WiFi passwords never leave your device
- No account, no tracking, no analytics on static codes
For everyone, everywhere
- 10 languages, including right-to-left Arabic · dark mode · mobile-friendly
For AI agents 🤖
FreeQrly is agent-native. Two free ways to generate codes without a browser:
MCP — add https://freeqrly.com/mcp (Streamable HTTP) to any MCP client.
| tool | auth | what it does |
|---|---|---|
generate_qr | none | static QR as SVG (data, size, color, bgcolor, ecc) |
dynamic_qr_create / list / update / delete / stats | Authorization: Bearer | editable dynamic codes, same free quota as the web UI |
HTTP API — GET https://freeqrly.com/api/qr?data=…&size=1024 returns SVG, no key. Authenticated dynamic endpoints (POST /api/codes, GET /api/me/codes, GET /api/codes/{code}/stats, PATCH, DELETE) take the same Bearer token, created in the dashboard under API Tokens.

Tech stack
Plain HTML/CSS/JS on Cloudflare Pages, plus a small Cloudflare backend (Functions + D1 + R2) for accounts, dynamic codes and the API. Zero build step for the frontend — pages are generated by Python scripts in tools/ and deployed via git push.

Only four source files matter for content work: index.html (homepage structure), assets/js/app.js (generator logic + translations), tools/gen-landing.py (landing page copy), assets/css/main.css (styles). Everything else is generated.
