Choose Cal.com.
If you want to own your data, save money, and avoid vendor lock-in, Cal.com is open source and community-driven.
What Actually Matters
No fluff — just the differences that affect your decision
Cal.com is open source (MIT). Calendly isn't. You can fork it, audit it, host it yourself — no permission needed. That matters.
Cal.com lets you self-host with Docker — your data, your rules. Calendly? Cloud only. If privacy matters, that's a dealbreaker.
Cal.com dominates with 49.0k GitHub stars vs 0. Bigger community = more plugins, more answers on Stack Overflow, faster bug fixes.
Cal.com is built in TypeScript — you can read the source, contribute, or fork it. Calendly is closed-source, so you're trusting their engineering.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
