Where each one falls short

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

Krayin

  • It is far less mature than EspoCRM, SuiteCRM or Vtiger, with thinner reporting, weaker forecasting and fewer built-in integrations, so evaluations that start from a feature checklist will not favour it.
  • Practical functionality such as certain telephony, messaging and marketing connectors sits in paid marketplace extensions from Webkul, so the free CRM plus the extensions you actually need is not free.
  • The roadmap is controlled by a single services company whose revenue depends on selling implementation and extensions, so there is a structural incentive against making the core complete.
  • You are responsible for the whole operational burden: PHP and MySQL hosting, backups, security patching, mail deliverability and upgrades, and a botched upgrade of a customised install is your problem alone.
  • The cloud hosting page does not publish prices, so the managed option that would remove that burden cannot be budgeted without contacting sales, which undercuts the transparency the open licence otherwise offers.

Plain

  • Foundation plan limited to 2,000 credits per month may be restrictive for high-volume teams
  • Pricing increases significantly from Foundation to Horizon ($35 to $299 per month)
  • No published pricing for Frontier (custom) plan
  • Additional seat costs ($99 per seat) add up for larger teams
  • Credit-based system requires monitoring usage to avoid overages
