Uptime, journeys, and APIs

Your site can be up while checkout is dead

Acumen Logs monitors uptime, user journeys, APIs, and background jobs, then alerts you in seconds. A page can return 200 while checkout, the API, or a nightly job is already broken.

Uptime is fine. Checkout, the API, and the backup are not.

What a ping misses

Four failures that still return a green homepage

Uptime monitoring tells you the server answered. The failures that cost money happen one layer deeper.

Uptime

The URL answers

Checks every minute from multiple regions, with status code, latency, and a text match. This catches an outage. It cannot tell you the buy button is dead.

Synthetic

The journey breaks

A real browser walks login or checkout on a schedule. You get the screenshot, the console, and the request. Describe the journey in a sentence, or record it in Chrome.

API

The response is wrong

Chain requests, pass a token between them, and check the JSON, not just the status code. A 200 with the wrong total is still a failure.

Heartbeat

The job never ran

Backups, invoices, and workers ping a URL when they finish. No ping, and you hear about it. The website can stay up the whole time.

Start with a URL. Add the journey, the API, and the job when you need them. Alerts go to email, Slack, Teams, desktop, SMS, or a webhook.

Setup

A first monitor in about a minute

Nothing to install on your servers.

Add a URL or a journey

Paste a URL for uptime, or describe a checkout in one sentence and let the AI draft the steps.

Choose who hears about it

Email on every plan. Slack, Teams, desktop, and webhooks from Solo. Set how many failures count before an alert.

Leave it running

Checks keep running. A failure arrives with the status, the timing, and, on a journey, the screenshot.

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.
