About the product
Streamline Your Scheduling Without Back-and-Forth
Tired of the endless email ping-pong just to schedule a meeting? You waste hours each week coordinating times, dealing with time zone confusion, and manually updating your calendar. The back-and-forth is not just frustrating—it's costing you valuable time that could be spent on what really matters.
What is Cal.com
Cal.com is an open-source scheduling infrastructure that eliminates scheduling hassles by letting others book time on your calendar based on your actual availability. It seamlessly integrates with your existing calendars and offers customizable booking pages that match your brand. Whether you're an individual freelancer, team leader, or enterprise with complex scheduling needs, Cal.com empowers you to take control of your time without writing a single line of code—unless you want to customize it further.
Key Capabilities
Calendar Integration : Syncs with Google Calendar, Outlook, and iCloud to prevent double bookings automatically, showing only truly available times to potential bookers.
Customizable Booking Pages : Create branded booking experiences with your logo, colors, and custom domains, giving clients a professional and cohesive experience that strengthens your brand.
Team Scheduling : Deploy round-robin and collective availability features to distribute meetings fairly across team members or schedule sessions requiring multiple participants.
Automated Reminders : Reduce no-shows by up to 80% with automated email and SMS notifications, allowing you to focus on preparation rather than chasing down appointments.
Developer-Friendly API : Build custom scheduling experiences using Cal.com's REST API and webhooks, enabling seamless integration with your existing software ecosystem.
Perfect For
Sales director Sarah was losing prospects due to scheduling delays. After implementing Cal.com with Salesforce integration, leads now book demos instantly from email campaigns. Her team's response time dropped from 3 days to under 1 hour, and conversion rates increased 35% in the first month.
Dr. Martinez needed a HIPAA-compliant way for patients to schedule appointments. Using Cal.com's Enterprise plan with SSO and custom branding, he created a seamless booking experience embedded directly on his clinic's website, reducing administrative calls by 62%.
Worth Considering
Cal.com has a steeper learning curve for non-technical users compared to simpler alternatives like Calendly. For developers who want to customize or self-host, it's unmatched, but some advanced team features require paid plans starting at $15/user/month. The free plan is generous for individuals, but enterprise features like HIPAA compliance and SSO require the higher-tier plans. Pricing: Freemium (Free for individuals, $15/user/month for teams).
Also Consider
Calendly: Better for non-technical users needing a simpler, more intuitive interface with minimal setup time.
SavvyCal: Offers a unique overlay calendar view that lets bookers see mutual availability more clearly.
Acuity Scheduling: Superior for businesses that primarily schedule paid services and need robust payment processing capabilities.
Bottom Line
Cal.com stands out as the most flexible and developer-friendly scheduling platform available, with a commitment to privacy through its open-source approach. If you value customization, data control, or need to build scheduling into your own applications, Cal.com offers unmatched capabilities that eliminate scheduling friction for you and your clients.
