Where each one falls short

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

JetBrains IntelliJ IDEA

  • High memory consumption and slower startup time compared to lightweight editors like Visual Studio Code
  • Refactoring can sometimes increase code line count and doesn't effectively support all modern programming languages
  • Occasionally misses dependencies between files requiring full rebuilds for consistency
  • Expensive subscription costs for Ultimate edition compared to open-source alternatives like Eclipse
  • Not all class name references are updated reliably when using search and replace functionality

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
