Cal.com vs Acuity Scheduling

Last updated October 2026

Cal.com

Cal.com is an open-source scheduling platform built for individuals, teams, and organizations that want full control over their booking infrastructure. The project is licensed under AGPLv3, which means anyone can inspect, modify, and self-host the code without paying a cent.

The free cloud plan covers the basics. You get a booking page, calendar syncing with Google and Outlook, and Stripe payment collection. There are no caps on the number of appointments you can take, and basic event types are included. For individuals and freelancers testing the waters, this is a low-risk starting point.

Where Cal.com starts to differentiate is at the team level. The Team plan, priced at $12 per seat per month on annual billing, unlocks round-robin scheduling, collective availability (where multiple team members must all be free), team analytics, and admin controls. Branding removal is included at this tier. For growing agencies, consultancies, or support teams, these features solve real coordination problems that a solo scheduling page cannot handle.

The Enterprise plan at $30 per seat per month adds SSO/SAML authentication, managed hosting, custom SLAs, and dedicated support. Organizations with compliance requirements or complex deployment needs will find this tier covers the gaps.

Self-hosting is the headline differentiator. If you want scheduling embedded directly into your product, or if you need to keep data on your own servers for regulatory reasons, Cal.com is one of the only options that lets you do this. The trade-off is that self-hosting requires infrastructure management: plan on $5 to $50 or more per month in server costs, plus the technical expertise to maintain it.

API access is available on all plans, which makes Cal.com a strong choice for developers building scheduling into custom workflows. The developer community around the project is active, and the documentation is thorough.

Acuity Scheduling

Acuity Scheduling, now owned by Squarespace, is a booking tool designed for service-based businesses: coaches, consultants, therapists, salons, and healthcare providers. It focuses on client-facing booking flows where the end customer picks a time, fills out intake forms, and pays in advance.

There is no free plan. Acuity offers a 7-day trial, after which you choose from three tiers. The Emerging plan starts at $16 per month on annual billing (closer to $20 on monthly billing) and supports a single staff calendar. You get a booking page, email reminders, Stripe and Square payment processing, and Zoom integration. For a solo practitioner, this covers the essentials.

The Growing plan at $27 per month is where Acuity becomes more capable. It supports up to six staff calendars, adds SMS reminders, enables group scheduling for classes or workshops, and introduces packages and subscriptions for recurring services. Acuity branding is removed at this tier. If you run a small practice with a handful of providers, this is the plan most businesses land on.

The Powerhouse plan at $49 per month scales to 36 staff calendars and adds custom API access, multiple time zone support, HIPAA compliance, and priority support. Healthcare practices that need to meet regulatory requirements will need this tier.

Acuity's strongest integration story is with Squarespace. If your website already runs on Squarespace, Acuity embeds natively with minimal configuration. Calendar syncing works with Google Calendar, Outlook, and Apple Calendar via two-way sync. For other integrations, you will often route through Zapier, which may involve its own subscription costs.

Payment handling is a notable strength. Acuity supports Stripe, Square, and PayPal, and it can manage deposits, packages, gift certificates, and recurring subscription payments. For service businesses where upfront payment reduces no-shows, this is well thought out.

The main complaints users raise center on pricing and the interface. There is no free tier to test beyond the trial. SMS reminders cost more because they require at least the Growing plan. The reporting tools are basic compared to dedicated CRM or analytics platforms, and the admin interface requires some patience to learn. Support is primarily email-based, with no live chat on lower plans.

How to choose

The decision between Cal.com and Acuity usually comes down to what kind of business you are running and how much control you want over the tool.

Choose Cal.com if you are a developer, startup, or team that values open-source software and wants API access from day one. The free tier is generous, self-hosting is a real option, and the team scheduling features (round-robin, collective availability) are designed for organizations coordinating across multiple people. If you are building scheduling into a product rather than just using it for your own appointments, Cal.com is the clear pick.

Choose Acuity if you are a service provider who books clients one-on-one: a therapist, coach, salon owner, or consultant. Acuity's intake forms, payment processing with multiple providers, and package or subscription billing are tailored for that use case. If your website is on Squarespace, the native integration removes friction. And if you need HIPAA compliance for a healthcare practice, Acuity offers it at a predictable price point.

For teams that need both developer flexibility and polished client booking, consider running Cal.com for internal scheduling while using a separate tool for client-facing payments and intake. Neither tool is perfect at everything, and the overlap between them is smaller than it first appears.

Where Fabric fits

Neither Cal.com nor Acuity manages the context around your meetings. What was discussed last time, which emails led to the booking, or what notes your team left in Slack: that information lives scattered across your apps.

Fabric is a personal cloud and context layer that connects 30+ apps, including Google Calendar, Gmail, and Slack. Its AI search pulls answers from across all your connected tools, so you can find a client's history before a session without opening five tabs. The AI assistant supports four models and can summarize threads, draft follow-ups, or surface relevant documents before your next appointment.

Fabric is free to start. Paid plans run $8 per month on annual billing or $10 per month billed monthly. The company also plants trees with every subscription.
