It's a split decision.
Choose Datadog for a broad platform spanning infrastructure, applications, logs, security and software delivery, with integrations including OpenTelemetry and major cloud providers. Choose AppDynamics for application-to-business visibility across hybrid and three-tier environments, SAP monitoring, and on-prem or private-cloud deployment options. Both have no free plan. Pricing differs by meter: Datadog lists AI credits, while AppDynamics lists CPU-core editions and token-based real user monitoring. Confirm the costs for your full workloads before committing.

02Pricing at real usage
Neither product has a free plan. AppDynamics offers a free trial for some tiers; the duration is not published. Datadog's listed AI Credits plan costs $500 per 500 credits per month when billed annually. On-demand credits cost $1.30 each. That is an AI-credit price, not a total price for the monitoring platform.
AppDynamics prices Infrastructure Monitoring Edition at $6 per CPU core per month, Premium at $33, Enterprise at $50, and Enterprise Edition for SAP Solutions at $95. Cisco Secure Application is $13.75 per CPU core per month. Real User Monitoring is $0.06 per 1,000 tokens per month. These are monthly equivalents billed annually; the pricing details say annual billing is 10% less than monthly, while monthly prices are available through the Cisco store. Seat limits and overages are not published. Model expected CPU cores, RUM tokens and AI-credit consumption before comparing totals.
03API, SDKs and integration
Datadog lists integrations with AWS, Azure, Google Cloud, Kubernetes, OpenTelemetry, OpenAI and SAP. That gives teams named options for connecting cloud, container and telemetry ecosystems. AppDynamics integrates with Splunk products, and its page names ThousandEyes integration for network intelligence.
The product pages do not identify API styles, SDK languages, CLI commands or documentation sets. Developers should check each vendor's API reference and SDK support for their languages, authentication model, ingestion path and export needs before planning implementation. The documented integration names are not a substitute for confirming which signals, services and deployment configurations each connector supports. Datadog is presented as a web platform; AppDynamics supports on-prem, private-cloud and public-cloud environments. Those deployment choices can affect how teams connect existing telemetry and network monitoring, so confirm compatibility with your specific stack.
04Open source, self-hosting and lock-in
The product pages do not identify an open-source licence for either product. Datadog is listed as a web platform, and self-hosting is not stated. AppDynamics is listed as self-hostable, with on-prem, private-cloud and public-cloud options; its platform material also describes hybrid deployment.
Neither product page specifies data-export formats or migration procedures. Before adopting either platform, ask the vendor how to export metrics, logs, traces, dashboards, alerts and configuration, and what remains usable after a contract ends. For AppDynamics, confirm which components can run in your chosen environment. For Datadog, confirm your data-retention and export path. The more dashboards, monitors, integrations and workflows you build around vendor-specific features, the more migration work you should plan for.
