Why teams move uptime monitoring off Datadog

Save thousands per year

At $12/test/month, Datadog Synthetic Monitoring costs $14,400/year for 100 endpoints. CronAlert costs $60/year for the same coverage. That's 240x cheaper.

Right tool for the job

Datadog is a full observability platform. If you just need to know when a URL goes down, you're paying for a fleet of features you don't use. CronAlert does one thing and does it well.

No setup complexity

Datadog synthetic tests require configuration, scripting, and often agent installation. CronAlert: add a URL, choose an interval, done.

Works alongside Datadog

Keep Datadog for APM and infrastructure. Use CronAlert for uptime monitoring and status pages. Webhook integration lets the two work together seamlessly.

Migrate from Datadog

Two ways to move your monitors to CronAlert

Import automatically

Get your API and application keys from Organization Settings in Datadog
Export your synthetic API tests:
curl -H "DD-API-KEY: KEY" -H "DD-APPLICATION-KEY: KEY" https://api.datadoghq.com/api/v1/synthetics/tests
Go to CronAlert Import Tool
Paste the JSON output and click Import

Only API tests are imported. Browser and multi-step tests are not supported.

Migrate manually

Log into Datadog, note each monitored URL
Sign up for CronAlert — free, no credit card
Click Add Monitor for each URL
Configure alert channels (email, Slack, Discord, webhook)

Frequently asked questions

Can CronAlert replace Datadog for uptime monitoring?

Yes, for uptime monitoring specifically. CronAlert is purpose-built for HTTP uptime checks, heartbeat monitoring, SSL monitoring, and status pages at a fraction of Datadog's cost. Keep Datadog for APM and infrastructure if needed.

How does CronAlert compare to Datadog Synthetics?

Datadog Synthetics supports scripted browser tests and multi-step API tests. CronAlert focuses on HTTP endpoint monitoring — checking that your URLs return a healthy response. For simple uptime checks, CronAlert is 240x cheaper.

Can I import my Datadog synthetic tests into CronAlert?

Yes, for API tests. Export your Datadog synthetic API tests via their API, then paste the JSON into CronAlert's import tool. Browser tests and multi-step tests are not supported as CronAlert focuses on HTTP endpoint monitoring.

Can CronAlert integrate with Datadog?

Yes. CronAlert supports webhook alerts, so you can send alerts to any service that accepts webhooks, including Datadog. You can also use CronAlert's REST API and MCP server for programmatic access.
