Questions
What clx does in your Cloudflare account, how counting and links work, and what it costs.
General
Do I need a Cloudflare account?
Yes. clx counts sites served by Cloudflare, and short links need a domain of yours there: clx.cx carries none of your traffic.
What does clx create in my account?
One worker, one D1 database and the routes of your sites and link host, with a working token of its own. Disconnecting removes what clx created and lists anything it could not; the working token you revoke yourself in Cloudflare — clx gives you the link.
Does it cost anything?
The free plan costs nothing and needs no card; the worker runs on your Cloudflare quotas.
Can I read the code?
All of it, on GitHub, under AGPL-3.0.
Analytics
Which sites can clx count?
Sites served by Cloudflare in the account you connect: a zone there or a subdomain of one. Ten sites on the free plan, 500 on the API plan.
How are bots told apart?
By known signatures in the browser string, headless browsers included: they are counted in their own report by kind and never mixed into views or visitors.
Can I get raw visits?
No: clx keeps no visit log, only counters. Reports come from the app and from the API.
What if I disconnect?
clx removes its worker, database and routes from your account and lists anything it could not; the totals on clx.cx go with your clx account when you delete it.
Short links
Can I use clx without a domain of my own?
No. Links live on your host in your Cloudflare account: clx.cx carries none of your traffic.
What happens to a printed QR code if the page moves?
Change the link’s target: the code and the QR code stay the same.
How many links can I have?
200 on the free plan, 10,000 on the API plan.
How is a link chosen by country?
By the country Cloudflare sees the click from; a device is a phone or a computer.
Site generators
Do my customers need their own Cloudflare accounts?
Yes: a counter runs in the account its site is served from. A customer connects it once with a bootstrap token, by hand or through your integration.
Can footprint scanners or ad blockers spot clx?
No signature in the page, the URLs or the answers is shared by clx sites or names clx, beyond the browser’s own API names. Someone watching can still see the behaviour — a same-origin POST answered with an empty 204.
Is there an SDK?
No: the API is plain HTTP with an OpenAPI contract, and AI agents have a walkthrough of their own.
What does it cost?
The API plan is switched on by request and is free for now; Workers Paid is never required.
Pricing
Do I need a card?
No: signing up and the free plan need none.
Does clx charge for traffic?
No: your visits and clicks go through your own Cloudflare account and its quotas, not through clx.cx.
What counts towards the limits?
Connected Cloudflare accounts, sites, links and API keys; visits and clicks are limited only by your Cloudflare quotas.
