The short version

  • Only Krayin has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Really Simple Systems the vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old
  • They diverge on capability: Krayin covers Lead pipelines, Really Simple Systems covers Contact management.
  • Prices and features above were last checked on 31 August 2026.

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.

Really Simple Systems

  • The vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old
