Cal.com is the open-source, self-hostable alternative for teams that want data ownership and no per-seat lock-in. If you need maximum capability and ecosystem, choose Acuity Scheduling; if open-source control matters more, Cal.com is the better-value pick.

Booking and calendar
Acuity Scheduling is online appointment scheduling; Cal.com is open-source scheduling infrastructure. On raw capability and feature depth, Acuity Scheduling is the stronger of the two — it covers more of the scheduling tool workflow out of the box and handles edge cases that Cal.com only reaches through workarounds or add-ons. Cal.com keeps a deliberately narrower surface area, which is a feature for teams that find broader tools cluttered. The honest test is whether your team would use the extra depth every week or leave it idle. Map your three most common scheduling tool tasks against each product before deciding, because feature lists rarely predict daily fit.
Ease of use
For everyday usability and onboarding, Acuity Scheduling is the easier of the two to live with. Because Cal.com is open source and self-hosted, standing it up means provisioning servers, handling upgrades, and owning backups before the first user logs in. Both Acuity Scheduling and Cal.com reward teams that adopt their default workflow rather than fighting it. Adoption is where most scheduling tool rollouts succeed or stall, so weigh who opens the tool every day — and how much training they will tolerate — more heavily than any single capability. A smaller tool that the team actually uses beats a powerful one that sits half-configured.
Team and customization
Cal.com wins on flexibility and control. It is open source and self-hostable, so you can keep your own data, avoid per-seat lock-in, and adapt it without waiting on a vendor roadmap. Acuity Scheduling is a managed, proprietary product — faster to adopt and less to maintain, but your data and workflow live on the vendor's terms. Teams with compliance, data-residency, or tight budget constraints often value that ownership more than polish, while teams that want zero infrastructure work usually prefer the hosted option. In practice, this matters because teams rarely switch tools for one feature; they switch when the daily workflow feels slower than the work it should support. Test one real use case in each before committing.
Pricing and value
On price, Cal.com is the better value for most teams. Acuity Scheduling starts around $16/user/month; Cal.com is open source and free to self-host. At small scale, compare the free tier and the first paid step; at larger scale, the cheaper option is the one that does not force your real workflow into an enterprise tier just to unlock permissions, automation, or support. Acuity Scheduling can still win on total cost if it replaces other tools you already pay for, so price the whole stack, not just the per-seat sticker. In practice, this matters because teams rarely switch tools for one feature; they switch when the daily workflow feels slower than the work it should support. Test one real use case in each before committing.
Integrations
Acuity Scheduling has the broader ecosystem — more native integrations, a larger community, and more templates, guides, and people who already know it. Cal.com connects to the common tools but leans on open APIs and self-built connections for anything niche. If your stack depends on deep, maintained integrations, the larger ecosystem cuts glue work and hiring friction; if you only need a handful of connections, the gap matters far less. Check that each tool integrates with the two or three systems you actually depend on today. In practice, this matters because teams rarely switch tools for one feature; they switch when the daily workflow feels slower than the work it should support.
