Customers who choose Pro cannot reach checkout, so they cannot pay for the plan.
The button showed a loading state, then the pricing page returned. Checkout never opened.
The checkout session appears not to be created, so the customer is returned to pricing.
Argelyx's reading of the observed facts, not a verified root cause.
Evidence
What worked
What Argelyx saw is kept apart from what it takes it to mean.
Screenshots, page addresses, network and console failures, element state.
Passing steps are reported too, so a fix starts from known ground.
Save the journeys that matter and Argelyx re-runs them daily or weekly, comparing every check with a recorded baseline. When an experience that used to work changes, you hear about it — before your customers do.

Mon — FriFriday · Regression detected
The checkout step failed after earlier checks showed no changes.
When a monitored journey changes, Argelyx sets the latest check beside the baseline: which steps broke, which recovered, how serious it is, and what to inspect first.

| Create an account | Passed | Passed |
| Select Pro | Passed | Passed |

Every account starts on Free — 3 one-time trial runs, no card needed. Paid plans add runs every billing period, more websites and journeys, and scheduled monitoring.
A customer journey you describe in plain language — signing up, choosing a plan, reaching checkout, submitting a form. Argelyx opens your live website in a real Chromium browser, on desktop or mobile, works through the journey step by step, and reports which steps worked, which failed, and the evidence for each.
No. It uses your public website the way a customer does, through the browser. It never needs your code, repository, hosting or server access — only proof that the domain is yours.
Uptime monitoring tells you a page responds. Argelyx tells you whether a customer can finish what they came to do. A page can load perfectly while its checkout button does nothing — uptime stays green, and only a test of the journey notices.
Those are frameworks for writing and maintaining test scripts. With Argelyx there is no script to write or repair: you describe the goal, Argelyx works out the steps on your live site, and you get a written report with evidence rather than a pass/fail log.
So Argelyx only ever tests websites their owners have authorised. You prove ownership once with a DNS record, an HTML file or a meta tag, and nothing is tested until it is confirmed. If a journey leads off your verified domain, the test stops rather than testing someone else's site.
It never touches your code, content or settings. It does what a customer would — clicking, typing and submitting forms — so a journey that creates an account creates a real account. It never enters payment card details or completes a payment, and it never attempts a CAPTCHA.
Argelyx stops at the block and tells you what it ran into — a CAPTCHA, a bot check, or a step that needs a person, such as a one-time login code — instead of trying to get around it. Describing a journey that stops before that step usually gets you a full result.
One test of one journey. A run counts once Argelyx has started testing your website; if something on Argelyx's side stops a test before it reaches your site, it doesn't count. Scheduled monitoring checks are runs too. Paid plans' runs reset each billing period; Free includes 3 one-time trial runs that don't reset.
Yes, on Pro and Agency. A monitor re-runs a saved journey daily or weekly and compares each check with a recorded baseline, so you hear when something that used to work stops working. Pro includes 1 monitor; Agency includes up to 5. Scheduled monitoring is rolling out gradually, so it isn't yet switched on for every workspace.
Yes, at any time, from Billing. A cancellation takes effect at the end of the billing period, and you keep your plan until then. Every account starts on Free, with no card needed.
