Alternatives to Cal.com
Open source scheduling infrastructure
Cal.com ranks #2 of 7 in Scheduling tools, with an Alt Score of 84. It is proprietary, freemium from $12/user/mo and available on Web, iOS, Android and Browser extension. 10 of 11 checklist rows are verified against a public source.
Individuals, teams, and businesses that need online scheduling and appointment booking, plus developers who want to build or embed scheduling into their own product rather than rely on a closed SaaS tool.
A Calendly-style booking platform with personalized booking links, calendar sync and conflict-free availability rules, buffer times, and automated reminders. It includes built-in video conferencing (Cal Video) alongside Zoom/Google Meet/Teams integrations, payment collection via Stripe, workflow automation, and team/round-robin routing. Being open source, the full codebase is available on GitHub and can be self-hosted instead of using the hosted cloud version.
Users set their availability and connect calendars (Google, Outlook, etc.); invitees pick a time from a shareable booking link or embedded widget, and Cal.com handles conflict checks, confirmations, and reminders. It can run as Cal.com's hosted SaaS or be self-hosted via Docker/the open-source repo, with an API for building custom scheduling flows on top.
