Methodology
All features were tested by creating real events on each platform in March 2026. Pricing was verified from each platform's public pricing page.
- Setup time: Measured from landing on signup page to having a shareable event link
- WhatsApp-native: Platform generates pre-filled WhatsApp message with event details (not just a copy-paste link)
- Automatic waitlist: System auto-promotes next person when a spot opens — no manual action
- AI Agent API: Platform offers Zapier (REST API + OAuth) tools or REST API for AI assistants to browse/create events
- Free Forever Score: 0-10 rating based on feature depth available without any payment
