It's a split decision.
Choose Datadog for broad observability across infrastructure, applications, logs, security, digital experience, and software delivery. Choose PagerDuty for incident detection, on-call coordination, triage, and response automation. The price comparison is not like-for-like: Datadog’s listed $500/month annual price covers 500 AI credits, not a published full-platform starting bill. PagerDuty has a free five-user plan; Professional is $21/user/month annually, while larger platform tiers have annual fees and plan-specific limits.

02Pricing compared
These prices are not like-for-like. Datadog lists $500 per month, billed annually, for 500 AI credits; on-demand credits cost $1.30 each. That figure is for AI credits, not a published starting price for Datadog’s full platform, so the available pricing does not establish the cost of monitoring infrastructure, logs or applications.
PagerDuty has a free plan for five users, with one on-call schedule, one escalation policy and 100 SMS or phone notifications monthly. Professional costs $25 per user monthly or $21 per user monthly when billed annually. Its larger platform plans carry annual fees: Starter is $2,800 a year and caps seats at 30; Essential is $12,000 a year. PagerDuty also lists add-ons for Professional, including AIOps and Runbook Automation. Compare the included limits and extras before treating either price as your likely bill.
03Features and depth
Datadog is the broader observability and monitoring choice in these product descriptions. Its coverage includes infrastructure, networks, containers, Kubernetes, serverless systems, cloud costs, storage and GPUs. Application tools include performance and service monitoring, profiling and dynamic instrumentation. It also lists log management, audit trails, error tracking, cloud security, real-user monitoring, session replay, synthetic monitoring and software-delivery tools such as CI visibility and DORA metrics.
PagerDuty is centered on incident operations: detecting incidents, coordinating on-call response, triaging alerts and automating work. Its feature set includes Paige for AI-assisted triage, AIOps signal intelligence, incident workflows and incident learning. The distinction matters when switching: PagerDuty’s listed strengths address response and reliability operations, while Datadog covers a wider set of systems and user-experience monitoring tasks. If the main need is network monitoring, Datadog explicitly lists it. If the need is escalation and coordinated response, PagerDuty’s plans specify on-call and escalation features. The descriptions do not establish that either product replaces every tool in the other’s category.
04Ease of use and learning curve
The published materials do not publish setup times, training requirements or a direct usability comparison. The breadth of Datadog’s listed monitoring, security and delivery tools may mean more product areas to evaluate; PagerDuty’s narrower incident-response focus may be easier to scope if on-call coordination is the main requirement. That is a difference in scope, not proof that one is simpler to use.
The review scores are close: Datadog scores 6 for ease of use and PagerDuty also scores 6. Both score 5 for value. PagerDuty’s free plan gives a small team a defined entry point, but its limits include five users and one on-call schedule. Datadog’s listed AI-credit price does not reveal the full-platform cost, so teams should confirm the products and usage they need before estimating setup or spend.
Questions people ask
What are some alternatives to Datadog?
The published product information does not name a list of Datadog alternatives. PagerDuty is a possible alternative for incident response and on-call coordination, but its described focus differs from Datadog’s broad monitoring, security and software-delivery coverage. Treat it as a fit for a specific job, not automatically as a full replacement.
What is PagerDuty used for?
PagerDuty is described as an operations platform for detecting, triaging and responding to incidents. Teams can coordinate on-call response, use AI-assisted triage and signal intelligence, automate operational work, and learn from incident data. Its plans include on-call and escalation features, with limits that vary by tier.
Does Datadog do network monitoring?
Yes. Datadog’s listed infrastructure-monitoring coverage includes networks, alongside infrastructure, containers, Kubernetes, serverless systems, cloud costs, storage and GPUs. The published pricing details do not give a full-platform starting bill, so confirm the cost of the specific monitoring products and usage you need.
Why choose Datadog?
Choose Datadog when you need one platform spanning areas such as infrastructure and network monitoring, application performance, logs, cloud security, digital experience and software delivery. Its listed scope is broader than incident response alone. But the published $500 monthly figure covers 500 AI credits, not a full-platform starting price.
