PostHog
- The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts

- Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
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- User interface considered outdated compared to modern IDE alternatives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
