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  • User interface considered outdated compared to modern IDE alternatives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

ToolJet

  • Free and Pro tiers cap end users at 50, which may be too low for apps needing broad internal distribution.
  • Enterprise pricing starts at a steep $3,000/month, a large jump from the $199/month Team plan.
  • AI credits reset monthly and do not roll over, penalizing uneven month-to-month usage.
  • Smaller integration and community ecosystem than more established players like Retool.
