Cal.com is an open-source scheduling and appointment booking platform for individuals and teams. It provides customizable booking pages, calendar availability, and workflows to coordinate meetings across multiple participants and organizations.

Key Features

  • Public booking pages with event types, buffers, limits, and configurable availability
  • Team scheduling features such as round-robin/collective scheduling and managed availability
  • Integrations for calendars and conferencing tools (e.g., Google Calendar, Microsoft, Zoom/Meet), plus webhooks
  • Embeddable booking components for websites and products (embed/iframe options)
  • Routing and intake forms to qualify requests and direct bookings to the right person/event
  • Payments support for paid bookings (via Stripe integration)
  • Multi-user and organization support with admin controls and role-based access options

Use Cases

  • Customer-facing appointment booking for sales, support, and professional services
  • Internal team scheduling (1:1s, interviews, office hours) with shared availability
  • Product-embedded scheduling for marketplaces or SaaS onboarding flows

Limitations and Considerations

  • Some advanced enterprise capabilities and managed services are offered as paid features; self-hosted deployments may require additional configuration for SSO, email, and integrations.

Cal.com is well-suited for organizations that want full control over scheduling UX and data while integrating with existing calendar and conferencing ecosystems. Its embeddable approach and team scheduling options make it useful both as a standalone scheduler and as scheduling infrastructure inside other products.

Rallly is a scheduling and availability polling app that helps groups find the best date/time for an event. You create a poll with multiple options, share a link, and participants vote on what works for them—making it useful for teams, clubs, and families.

Key Features

  • Create scheduling polls with multiple date/time options and a shareable link
  • Participant voting to identify the best option (Doodle-style group availability)
  • Time zone-aware interface to reduce confusion for distributed participants
  • Optional participant comments/notes per poll (for clarifications and context)
  • Email notifications/reminders (requires SMTP configuration)
  • User accounts and authenticated poll management (with optional “guest” participation depending on configuration)
  • Admin/config-driven deployment options (environment variables), suitable for Docker-based hosting

Use Cases

  • Coordinating a team meeting across time zones without back-and-forth emails
  • Scheduling community/club events where attendees choose among several slots
  • Collecting availability for interviews, lessons, or small group sessions

Limitations and Considerations

  • Primarily focused on polling-based scheduling; it is not a full calendar suite (no CalDAV server or full agenda features)
  • Some functionality (notifications) depends on external email/SMTP setup

Rallly is a lightweight alternative to commercial scheduling poll tools, designed for quick event coordination with a clean web UI. It fits best when you need a simple “vote on times” workflow rather than a full booking system.
