Datadog Synthetics strengths
- Full observability stack (APM, logs, metrics, RUM)
- Deep integration with cloud infra and Kubernetes
- Very large ecosystem of dashboards and integrations
Where it falls short
- Bill shock is common — usage-based pricing across many SKUs
- Overkill for teams that just need website monitoring
- SEO/content monitoring not part of the platform
Choose Datadog Synthetics when
You already run Datadog for APM and want synthetic checks in the same pane of glass.
Lemwatch advantage
Lemwatch delivers site-level uptime, SEO and visual checks at a flat monthly price with no metered-per-run surprises.
Quick Summary
Datadog is best-in-class for full-stack observability — APM, logs, infrastructure — and priced for teams that need all of it. Lemwatch covers the website-monitoring slice (uptime, Core Web Vitals, SEO, security, status pages) at a fraction of the cost. Most teams end up running both, or replacing Datadog Synthetic Monitoring alone.
- Datadog Synthetic starts at $7/test/month; Lemwatch Pro is $19/month flat for 50 sites
- Lemwatch adds SEO, broken-link, and security-header monitoring Datadog doesn't ship
- No agents, no instrumentation — Lemwatch monitors from a URL in under 5 minutes
- Keep Datadog for APM/logs/infra; swap in Lemwatch for the website-monitoring spend

How to Switch from Datadog
Migration takes less than 15 minutes. Here's your step-by-step guide.
Export your sites from Datadog
Pull your monitor list out of Datadog — most tools offer a CSV export, or you can copy the URLs straight from the dashboard.
Create your free Lemwatch account
Sign up for the free tier — 10 sites, all check types, no credit card. Run it alongside Datadog while you compare.
Import and map your monitors
Paste or bulk-upload the URLs you exported from Datadog. Lemwatch auto-detects the platform, SSL state and sitemap for each one.
Rebuild your Datadog alert routing
Point alerts at the same channels you use today — email, Slack, Discord, Teams, PagerDuty or webhook — then set thresholds to match your Datadog config.
Run both in parallel, then cancel Datadog
Give it one billing cycle. Once Lemwatch alerts match Datadog's on the same incidents, cancel and keep the history in Lemwatch.

Datadog vs Lemwatch FAQ
Datadog vs Lemwatch: where each tool actually wins
Datadog and Lemwatch are usually framed as competitors but they solve different halves of the same problem. Datadog is an observability platform — it instruments your application, your hosts, your containers, your logs, and your traces, then correlates them so an SRE can debug a production incident in real time. Lemwatch is a website-monitoring platform — it watches the outside of your site (uptime, page weight, Core Web Vitals, SEO health, security headers, SSL, domain expiry, content drift) and tells the marketing or growth team when something user-facing is broken.
The pricing models reflect the divergence. Datadog charges per host for infrastructure, per million log events for logs, per test for Synthetic Monitoring, and per session for RUM. A mid-sized SaaS team monitoring 25 websites with Datadog Synthetic alone typically lands in the $150-300/month range before the rest of the platform; add APM and logs and the bill scales fast. Lemwatch is flat-rate: Free for 10 sites, Pro at $19/month for 50 sites with every feature on, Agency at $59/month for 150 sites with white-label and team seats. The trade-off is depth — Lemwatch has no application tracing, no log search, and no infra metrics.
The most common pattern we see is teams running both. They keep Datadog for production engineering — APM dashboards for the backend team, log aggregation for compliance, infra metrics for the on-call SRE — and move all of their website-monitoring spend (Synthetic Monitoring, the marketing site uptime checks, the status pages) over to Lemwatch. The net result is usually a 60-80% reduction in the Datadog bill with no loss of coverage, plus added SEO and security monitoring that Datadog doesn't ship at all.
If you're a small team without a dedicated SRE — founders, an agency, a marketing-led org — Lemwatch alone usually covers what you need. If you're past the inflection point where engineers spend real time in observability tooling, keep Datadog for that work and use Lemwatch to take the website slice off Datadog's bill.
What Datadog does that Lemwatch doesn't
Distributed tracing across microservices, log search and live tail, container and Kubernetes monitoring, custom application metrics, profiling, RUM session replay, advanced anomaly detection, and a massive integration catalogue. None of these are on the Lemwatch roadmap — they're a different product category.
What Lemwatch does that Datadog doesn't
SEO crawling with indexation tracking, broken-link detection, security-header grading, SSL and domain expiry forecasting, money-page assertion monitoring, white-label client reporting, the Carbon Footprint module, and a Free tier. Datadog's Synthetic Monitoring overlaps on uptime checks but doesn't ship any of the rest.
