Uptime, journeys, and APIs

Your Site Can Be Up While Checkout Is Broken

Acumen Logs monitors uptime, user journeys, APIs, and background jobs, then alerts you when something fails. A page can return 200 while checkout, an API, or a scheduled job is already broken.

What a ping misses

Four Failures Your Uptime Check Can Miss

Uptime monitoring tells you a server responded. But checkout, API, and background job failures can still cost you revenue.

Uptime

The website responds

Check your website from multiple regions for availability, response time, status codes, and matching text. This catches outages, but not every broken user journey.

Synthetic

The user journey fails

Test login and checkout in a real browser on a schedule. Build a journey from a prompt or record it in Chrome, then inspect screenshots, console errors, and requests.

API

The API responds incorrectly

Chain requests, pass tokens between steps, and validate JSON responses. A successful status code can still hide incorrect data.

Heartbeat

A scheduled job goes silent

Backups, invoices, and workers check in when they finish. If a check-in is missed, you get alerted even while the website remains online.

Who it's for

One product, many ways teams use it

Development teams

A journey on login and checkout, an API check behind them, and a Slack alert when a deploy breaks either one.

E-commerce

The purchase flow, the payment API, and the certificate, watched together so a dead checkout is not a surprise in the morning.

Hosts and agencies

Many client sites in one account, branded status pages, and the WHMCS module when monitoring is part of what you resell.

FAQ

Frequently Asked Questions

Where should I start?

Most teams start with uptime monitoring on their key URLs, then add a synthetic journey on the path that makes money, such as checkout or sign-up.

Do I need a separate account for each product?

No. Every product lives in the same account and dashboard, with the same alert channels.

What is the difference between uptime and synthetic monitoring?

Uptime confirms the server answers. Synthetic monitoring runs a real browser through a journey, so it catches a broken button or a script error while the homepage still loads.

Do I need to write code?

No. Record a journey with the Chrome extension, build it in the no-code builder, or describe it in a sentence and let the AI build it.

Show all questions Show fewer questions

Can I share results with clients?

Yes. Status pages can be public or private, and you can share test data with your team or your clients.

Is there a free plan?

Yes. The free plan needs no credit card and includes 10 uptime, SSL, and WHOIS checks, 60 synthetic tokens a month, email alerts, and a status page.
