PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method

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
