The choice is platform correlation versus focused outside-in monitoring. Datadog connects failed synthetic tests to APM, logs, RUM, and infrastructure. Webalert focuses on availability, alerting, and status communication. That is the useful frame for Datadog vs Webalert in 2026.
The short answer
Choose Datadog for the capabilities in its column that your team genuinely uses. Choose Webalert for focused HTTP/HTTPS, TCP, DNS, ping, and heartbeat monitoring with multi-region confirmation, SSL alerts, status pages, and incident alerting. Neither choice is a universal upgrade.
| Dimension | Datadog | Webalert |
|---|---|---|
| What it is | Full observability platform; synthetics are one module | Focused uptime, alerting, and status communication |
| Pricing model | Usage-based: $5 per 10,000 API test runs, $12 per 1,000 browser runs (annual billing) | Plan-based: Free, €9/month Starter, €29/month Business |
| Test types | API, browser, multistep, mobile, private locations | HTTP/HTTPS, TCP port, DNS, Ping/ICMP, heartbeat |
| Correlates with APM, logs, and RUM | Yes — that is the main reason teams choose it | No |
| Multi-region checks | Yes | Yes |
| Public status pages | Not the product's focus | Included on every plan |
| Best fit | Teams whose responders investigate in Datadog | Teams that need independent outside-in checks |

Pricing and packaging
Datadog publishes $5 per 10,000 API test runs and $12 per 1,000 browser runs on annual billing. Webalert prices by plan and monitor count; current plans show Free, €9/month Starter, and €29/month Business. See the current Webalert pricing and feature matrix rather than assuming every feature is on every plan.
Choose Datadog when
- Your responders investigate in Datadog APM, logs, and RUM.
- You need browser, mobile, multistep, or private-location synthetic tests.
- Your Datadog configuration is managed through API or terraform.
Choose Webalert when
- Most checks are straightforward HTTP, TCP, DNS, ping, or heartbeat availability.
- You want a separate outside-in failure domain.
- You want status pages and incident alerting without adopting an observability suite.
Important limitation
Webalert does not replace Datadog APM, logs, RUM, mobile tests, browser journeys, or private locations. Datadog is not automatically wasteful when those correlations shorten incidents. This is why a hybrid can be the right answer: keep the specialist workload and move only simple outside-in checks.
Migration advice
Use Datadog usage metrics to group tests into basic API, browser, multistep, and mobile. Move plain endpoint checks first. Keep scripted tests in Datadog, run both for one release cycle, and remove only tests with demonstrated parity.
