Pick your use case
Know what changed.Before your customers do.
Simrix Monitor walks your critical journeys in a real browser, spots the changes that matter, and tells you what broke with a screenshot and a plain-English summary.
Built for the small businesses and agencies that lose orders when checkout, login or signup quietly breaks.
Experience your checkout the way a shopper does. Free.
Give us your store address and we open your homepage, find and open a product page, click add to cart, then load the cart. You get a screenshot of every step and a plain-English note on anything that did not work.
- No account, no card, nothing to install
- It never signs in, enters card details or places an order
- Your address, email and screenshots are deleted after seven days
It takes just minutes.

Each step is reported on its own. We look for a product on your homepage, behind your Shop link, in your categories and in your sitemap. If we still cannot find one, we say where we looked, rather than calling the step a pass.
See exactly what happens when something breaks
Every alert opens onto the same report: the step that failed, the screenshot taken at that moment, the final URL and status code, and a plain-English summary of what went wrong.
Your monitor checks on the schedule you set
A step fails, or a page changes in a way that matters
The screenshot and step detail are captured at that moment
You get an alert with the evidence already attached
Catch expensive issues early
A checkout that broke overnight. A pricing page someone edited by mistake. A competitor move you hear about a week late. Each one is easy to miss when nobody is watching for it.
Catch broken workflows before customers report them
Monitor critical flows like login, checkout, signup, and more. Get alerted as soon as a check finds it, with screenshots and step context ready to review.

Track competitor and market pages without manual checking

What every monitor gives you
Point a monitor at a journey or a page, choose how often it should be checked, and the evidence you need when something goes wrong is collected for you.
Workflow monitoring
Check real browser journeys like login, checkout, signup, and key forms.

Alerts with evidence
The screenshot, the step that failed and a plain-English summary, as soon as a check finds a problem.
Scheduled checks
Check as often as every minute, or every 6 hours on Free.
Alerts land where your team already looks
Email, Slack and webhooks are built in. Everywhere else receives that same webhook through a relay you point at it, and the docs walk through each one step by step.
Through a webhook
Why the difference matters
Microsoft Teams, Discord and Google Sheets each expect their own message format, and Simrix Monitor does not have an app inside any of them. A relay such as Zapier or Make takes our webhook and reshapes it into what they expect. We would rather say that plainly than put three more logos on this page.
New product. Check it yourself.
Simrix Monitor launched recently, so there are no customer quotes on this page yet, and we are not going to invent any. Run the free checkout check on your own store instead, with no account and no card, and judge the evidence yourself. Real names will appear here as customers agree to share them.
- Real browser checks
- Screenshot and failed step on every alert
- Plain-English summaries
Frequently asked questions
Everything you need to know about Simrix Monitor.
What types of workflows can I monitor?
You can monitor real browser flows like login, checkout, signup, forms, navigation paths, and other important customer journeys, plus track visual and content changes on key pages.
What happens when a monitor fails?
Simrix Monitor records the failed step, timing, final URL, screenshot evidence, and summary context so you can understand what happened quickly.
How does change detection work?
Simrix Monitor compares monitored page output over time and flags meaningful visual, content, and structural changes so teams can review what changed without manually checking pages.
Is this only for technical teams?
No. It is designed to be approachable for small businesses, operators, marketers, agencies, and product teams that need visibility without heavyweight QA tooling.
How often can monitors check?
Free checks every 6 hours. Starter checks every 30 minutes, Growth every 15 minutes, Pro every 5 minutes, and Agency as often as every minute. You choose the interval per monitor, up to whatever your plan allows.
Is there a free trial?
Yes. Starter, Growth and Pro each start with a 14-day free trial and no card. Free needs no trial at all, and Agency is set up with us directly.
Ready to monitor what matters?
