Tools
QRFLOW runs in four places: on your own website as an embedded generator, inside your code through a REST API, inside Claude or ChatGPT as a connector, and here in the browser. Three of the four are free and two of them need no account at all. This page is the short version of which one fits which job.
Which one do you need
| Tool | Best for | What you need | Account | Cost |
|---|---|---|---|---|
| Embeddable generator | A blog, a docs page, a client site | Somewhere to paste HTML | No | Free |
| REST API | An app, a dashboard, a batch job | An API key | Yes | Business, $29/mo |
| AI connector | Making a batch without a form | A free account | Yes | Free |
| The generator | One code, once | Nothing | No | Free |
Embeddable generator
One line of HTML puts a working generator on your own site.
Your visitors type a link and download a code without leaving your page. It renders in its own boundary, so your CSS cannot break it and it cannot touch yours.
REST API
Make, re-point and count codes from your own code.
Scoped keys, 600 requests a minute, webhooks on every scan, and an OpenAPI document you can generate a client from.
AI connector
Ask Claude or ChatGPT for a code in plain words.
A Model Context Protocol server with eleven tools. Listed in Claude's connector directory, so adding it is two presses.
The generator
Make a code here, right now.
URL, Wi-Fi, contact card, phone, email, SMS and location codes, with PNG and SVG downloads and no sign-up in the way.
Put it on your site in one line
The fastest of the four. Paste this where you want the generator and publish.

QRFLOW is in Claude's connector directory, so adding it takes two presses. Other assistants take the server address.

- Which QRFLOW tool should I use?
- If you want a generator on your own website, use the embed: one line of HTML, free, no account. If you are writing software, use the REST API on the Business plan. If you want to make codes by asking, connect the AI connector in Claude or ChatGPT. If you just need one code, make it on the home page.
- Is the embeddable generator really free?
- Yes, on as many sites as you like, including client sites. A small line crediting QRFLOW.codes sits under the generator and that is the only condition. No account, no API key, no usage cap.
- Do I need an account to use any of these?
- The embed and the generator work with no account at all. The AI connector needs a free account so codes land in a dashboard you own. The API needs a Business plan, because keys and webhooks are Business features.
- Can a QR code made with these be changed after printing?
- Yes, if it is a dynamic code. Every tool here can make one. Free accounts get one dynamic code; paid plans make every code dynamic. A static code cannot be changed by anyone, ever, because the destination is baked into the pattern.
- What is the difference between the API and the connector?
- The API is for software you write: keys, webhooks, predictable responses. The connector is for a person working in a chat window: it is the same account and the same codes, reached by asking rather than by writing a request.
- Will the embedded generator slow my site down?
- No. The script tag is async, so your page finishes rendering and the generator loads after it. Nothing above it waits, and it adds no blocking request to your critical path.
