What uptime and synthetic checks cover well
Uptime monitors ping a URL on an interval and alert when it stops returning a healthy response. They are simple and reliable at exactly that job, telling you the site is reachable right now.
Synthetic monitoring tools go further and script a browser to click through a flow. Tools like Checkly, Datadog Synthetics, Pingdom, UptimeRobot, and Rainforest are strong at this, and if you have engineers who maintain the scripts, they are worth running.
What neither one tells you
These tools largely stop at the edge of your own app, at page rendered or endpoint returned 200. They do not, on their own, confirm the paid order reached Stripe, then your CRM, then the inbox, reconciled as one transaction across every system.
And they do not translate a break into the one number an owner actually needs, the dollars at risk while it stays broken. That reconciliation across systems, tied to a dollar figure and written for a non-technical owner, is the gap Smoke Run was built to fill.
The questions each one answers
A plain side by side.
- Is the site up right now? Uptime monitors answer this best. Smoke Run sees it too, as a side effect of walking the path.
- Did the code throw an exception? Error trackers answer this best.
- Did a real checkout complete end to end? Smoke Run answers this, because a synthetic customer actually buys.
- Did the paid order reach your CRM and inbox? Smoke Run answers this, reconciled across every connected system.
- What is the leak costing you, in dollars? Smoke Run answers this, as a conservative range with the math shown.
Do you need both?
Usually yes, and that is an honest answer, not a sales one. Keep your uptime monitor, because it is good at uptime. Keep your error tracker. Add money-path monitoring for the revenue chain those tools were never meant to watch.
If you are a solo owner or a small team without engineers maintaining browser scripts, money-path monitoring is often the first layer worth adding, because it watches the part that directly carries your income and it needs no scripting from you.
How Smoke Run watches the money path
Start with a free teardown that checks your funnel from the outside. When you want continuous coverage, connect Stripe with a read-only key, your CRM, and your email, and Smoke Run runs a synthetic customer through the full path on a schedule, reconciles the sale across every system, and alerts with the step and the dollars when it breaks.
Every connection is read-only, so the count of changes we made to your systems stays at zero, and you can revoke access in one click.
