The short version
- Only Eclipse has a free tier, so it costs nothing to try first.
- Each has a real cost: Eclipse high memory consumption and CPU usage, especially with multiple plugins installed; Datadog consumption-based pricing model makes costs hard to predict and can scale quickly
- They diverge on capability: Eclipse covers Java development environment, Datadog covers Infrastructure monitoring.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Eclipse
- High memory consumption and CPU usage, especially with multiple plugins installed
- Slow startup times and performance degradation with large projects or many open editors
- Requires configuration of eclipse.ini file to optimize heap sizes for adequate performance
- User interface considered outdated compared to modern IDE alternatives
- User base fell from 39% of Java developers in 2024 to 28% in 2025, indicating market decline
Datadog
- Consumption-based pricing model makes costs hard to predict and can scale quickly
- Add-on modules significantly increase costs: custom metrics, indexed spans, extended retention
- No free tier for production monitoring
- High costs for organizations with large amounts of log data or high-cardinality metrics
