Where each one falls short

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

Kissmetrics

  • Overages are added automatically to the next invoice rather than blocked, so exceeding an event allowance bills without a decision point
  • The free plan allows 100,000 events a month
  • Per event rates fall with volume, from $0.20 per 1,000 events on Growth to $0.10 on Gold, so smaller customers pay double per event
  • The vendor states Growth, Silver and Gold are the identical product, so the paid tiers differ only in unit price and volume
  • Anything above 5 million events is custom priced

Optimizely

  • No pricing is published and no minimum is stated
  • Every plan is individually packaged, so no two quotes are necessarily comparable
  • Reaching a figure requires a demo or sales conversation
