Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

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  • User interface considered outdated compared to modern IDE alternatives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
