  • They diverge on capability: Assistant.to covers In-email scheduling, Zeeg covers European hosting.
  • 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.

Assistant.to

  • No publicly published pricing rates on website
  • Requires scheduling demo or contacting sales to obtain pricing information
  • Free trial available but no specific trial duration mentioned

Zeeg

  • Single sign-on and SCIM only appear on the Scale tier at EUR 30 per user per month, so an organisation that needs identity governance for a hundred occasional bookers pays a premium tier price for every one of them.
  • Round robin routing, which many teams treat as the basic reason to buy a team scheduler, is held back to Business at EUR 16 per user, well above where competitors place it.
  • The integration catalogue and surrounding ecosystem are much smaller than Calendly, so a workflow that depends on a niche CRM or an existing Zapier-style recipe may need building rather than switching on.
  • There are no native mobile apps, so staff manage availability and bookings through the browser, which is workable but noticeably weaker for people scheduling from the road.
  • The CRM features are light by design and will not replace a real pipeline tool, so teams risk splitting contact data between Zeeg and their actual CRM and then reconciling it.
