Calendso — Free & Open Source for Startups

Deal Highlights

Calendso (Cal.com) — Open-Source Scheduling You Control

Cal.com (formerly Calendso) is an open-source scheduling infrastructure that you can self-host for complete control over your booking experience. It provides everything Calendly does — booking pages, calendar sync, team scheduling, and workflows — with the freedom to customize, brand, and host on your own domain.

Why Open-Source Scheduling

Calendly controls your booking data, limits your branding, and charges per seat. Cal.com is open-source — self-host it, customize every pixel, own your data, and pay nothing per user.

Full Scheduling Platform

Individual and team booking pages. Round-robin and collective scheduling. Recurring meetings. Buffer times. Minimum notice periods. Custom availability per event type. Payment collection via Stripe. Workflows with email and SMS reminders.

Cal.com vs Calendly

Calendly is more polished and easier to set up. Cal.com is open-source, self-hostable, and free for unlimited users. Calendly charges $12/user/month. Cal.com self-hosted costs $0. For teams that value control and cost savings, Cal.com wins.
