Datadog alternative for uptime and synthetic monitoring, at a flat price
Short answer: Datadog Synthetic Monitoring is powerful and priced by usage, so a simple uptime check running every minute from several regions can turn into a bill nobody forecast. AlertPing is the alternative when what you actually need is dependable uptime, API, SSL, port and cron monitoring on a flat published plan from $19 a month, with 30-second checks, three-region confirmation before it pages you, and SMS on every plan. If you need synthetics stitched into full APM, logs and traces, we say plainly below where Datadog is the better call.

the honest frame
Datadog is a lot of platform, so here is the real difference
Datadog is not a monitoring tool, it is an observability platform: infrastructure metrics, APM traces, log management, real user monitoring and synthetic tests, all correlated in one place. Its Synthetic Monitoring does real-browser tests, multi-step transaction flows and private-location checks that few focused uptime tools can match. If you already run on Datadog and want a failed check to link straight to the trace and the log line behind it, staying inside Datadog is a fair choice.
The catch is the pricing model. Synthetics bills by test run: roughly $5 per 10,000 API test runs and $12 per 1,000 browser test runs, multiplied by how often each test fires and how many locations it runs from. Push a browser check to every minute across five regions and the run count, and the bill, climbs fast. AlertPing does the uptime slice on a flat, published plan instead: you pick a tier and the price does not move when a monitor checks more often. That is the difference in one line.
Flat, forecastable price
$19 to $189 a month by plan, not per test run. Your bill does not jump because you raised a check frequency or added a region. See the pricing page.
Confirm before it pages
Every failed check is re-run from three regions (Virginia, Frankfurt, Singapore) before you get an alert, so one flaky network path does not wake the on-call at 3am.
Live in a minute, not a rollout
No agents to deploy, no host to instrument. Paste a URL, set an interval, add a phone number, and the monitor is running. SMS, email, Slack and webhook alerts are on every plan.

AlertPing vs Datadog Synthetics, side by side
Datadog figures below are list rates from datadoghq.com and its synthetics pricing is usage-based, so your real number depends on run volume. Confirm current rates before you decide. Our plans are on the uptime monitoring pricing page.
| AlertPing | Datadog Synthetics | |
|---|---|---|
| Pricing model | Flat per plan, $19 to $189/mo | Usage-based, per test run |
| Uptime check cost | Included in the plan at any interval | ~$5 per 10,000 API runs, more per region and frequency |
| Browser / real-browser tests | No, HTTP checks with body and JSON assertions | Yes, ~$12 per 1,000 browser runs, multi-step flows |
| Fastest check interval | 30 seconds (Team plan), 15 seconds on Enterprise | Down to 30 seconds, billed per run |
| Multi-region confirmation | 3 regions confirm before alerting | Multi-location, private locations available |
| Correlated APM, logs and traces | No, uptime and status only | Yes, the core reason to use Datadog |
| SMS alerts | Included on every plan | Via integrations and on-call add-ons |
| Hosted status pages | 1 to 20 by plan, custom domain on Business | Not a native product feature |
| Setup | Paste a URL, no agent to install | Test config within the wider Datadog platform |
Read that honestly and the split is clear. Datadog wins when synthetics are one tile in a full observability stack: you want browser tests and multi-step transactions correlated with traces, logs and infrastructure metrics, and you have the budget and the appetite for usage-based billing. AlertPing wins when you want the uptime, API, SSL, port and cron slice done well, on a flat bill you can put in a budget, with a confirmation step that cuts false pages and SMS included.
Choose AlertPing if
- You want a flat, published bill and no surprise usage charges when you check more often.
- Your need is reliable uptime, API, SSL, port and cron monitoring, not full APM.
- A three-region confirmation step before paging is worth real money to your on-call.
- You want a hosted status page and SMS included, live in under a minute with no agent.
Choose Datadog if
- You already run Datadog and want a failing check to link straight to the trace and log behind it.
- You need real-browser tests, multi-step transaction flows or private-location checks inside a firewall.
- Synthetics is one part of a broader observability rollout with the budget for usage-based pricing.
Those are real strengths, and we would rather you pick the tool that fits than churn in a month.

questions
Datadog alternative questions, answered
What is the best Datadog alternative for uptime monitoring?
For the uptime slice specifically, a focused monitor with flat pricing is usually the better fit than Datadog's usage-based synthetics. AlertPing checks sites, APIs, ports and cron jobs every 30 seconds from three regions, confirms outages before paging, and costs $19 to $189 a month flat. If you need synthetics correlated with traces and logs, Datadog itself is the stronger tool.
Why is Datadog synthetic monitoring so expensive?
Because it bills per test run. A price like $12 per 1,000 browser runs looks small until you multiply it by a one-minute frequency and several regions, which turns into millions of runs a month. Flat-priced tools charge for the plan, not the run count, so raising a check interval does not change the bill.
Does AlertPing replace Datadog?
Only for the monitoring part, and honestly. AlertPing does uptime, API, SSL, port and cron checks with alerts and status pages. It does not do APM, log management, real user monitoring or infrastructure metrics. If those are why you use Datadog, keep them; many teams run AlertPing alongside for external uptime and to avoid metering simple checks.
Can AlertPing do browser or transaction testing like Datadog?
Not full real-browser, multi-step synthetics. AlertPing runs HTTP checks with body-content and JSON assertions, so it can verify an API returns the right field or a page contains the right text, but it does not script a click-through of a checkout flow. For that, Datadog or a dedicated synthetic tool is the right pick.
Reliable uptime monitoring on a flat bill
30-second checks from three regions, SMS on every plan, and a hosted status page, flat from $19 a month with no per-run metering. Running in under a minute.
