The short answer
Compare hosted Cal.com for individual or team scheduling, Acuity for appointment intake and change rules, and Cal.diy only if you can maintain a separate self-hosted product. Payments and prepaid packages alone no longer distinguish Acuity from Calendly: Calendly now documents both. Choose a replacement for the specific booking step that fails in your current setup.
Research-based decision guide. Vendor documentation checked September 10, 2026. This is not a hands-on product test. Read our disclosure.
Start with the booking workflow
The most useful Calendly alternative is the one that fixes a specific problem: too few event types, appointment intake that lives elsewhere, a cancellation rule clients can bypass, or appointments assigned to the wrong person. Start with that failure, then choose a shortlist.
For a hosted alternative, compare Cal.com for individual and team scheduling and Acuity for service intake, deposits, and appointment changes. Consider Cal.diy separately if you want to run the software yourself. It is a different product with a different feature boundary.
Keep Calendly in the comparison. Its current documentation includes prepaid meeting packages and standalone payment links, so selling sessions does not automatically require a move to Acuity. The package and payment-link features require Stripe and an eligible paid plan. This corrects the older shortcut that treated Calendly as meeting links only. Calendly payment offerings.
This shortlist follows official documentation checked on September 10, 2026. It is not a report of hands-on testing. The scenarios below are proposed checks for your own trial, with pass conditions you can record.
Meeting links versus paid appointments
Describe the booking you need in one sentence. These three examples deliberately keep the visitor's goal separate from the product name.
| Illustrative workflow | What must happen | Start your evaluation here | Reason to reject a candidate |
|---|---|---|---|
| Free introductory call with one consultant | Offer two call types, avoid personal calendar conflicts, show the visitor's local time | Hosted Cal.com; compare against the Calendly plan you already use | A required calendar or event type is unavailable on the intended plan |
| Paid session with a deposit | Collect service intake, connect payment to the appointment, apply a late-change policy | Acuity and your current Calendly configuration | Staff cannot explain what is booked, paid, and still owed |
| New enquiries shared by two employees | Offer a suitable time, assign an eligible employee, preserve context after a change | Cal.com Teams, Calendly Teams, or Acuity if the enquiry becomes a service appointment | Assignment chooses someone who cannot deliver the service, or a reschedule loses ownership |
These are starting points for testing, not exclusive product categories. For example, Acuity documents both priority and round-robin assignment when availability is pooled across calendars. “Team scheduling” alone is therefore too broad to decide the winner. Acuity calendar pooling.
Employee shift planning is outside this comparison. Giving clients an appointment with an available employee is a different task from creating that employee's working rota.
Compare calendars, forms, and payments
Hosted Cal.com for an individual or team shortlist
Cal.com's Individuals plan lists one user, unlimited event types and connected calendars, and Stripe and PayPal payments. Its Teams plan adds shared availability, round-robin scheduling, collective event types, and routing forms. These are hosted plan entitlements, not promises about Cal.diy. Cal.com pricing.
That makes the hosted individual plan worth evaluating when your problem is several kinds of appointments across several calendars. A busy personal calendar and a work calendar should both be part of the trial. Add a conflict in each, then inspect the booking page from a separate browser session.
For a team, write the assignment rule before configuring it. “Give the meeting to an available consultant” and “give it to the consultant who owns this client” are different requirements. Verify the exact routing input, plan, and integration needed for the second. A routing feature on a pricing page does not prove it matches your client ownership model.
Acuity for service intake and appointment rules
Acuity lets you attach custom intake forms to selected appointment types and allow clients to edit responses after booking. Its payment settings include fixed or percentage deposits. Those are concrete reasons to investigate it when services need different questions or a deposit tied to the booking. Acuity intake documentation, payment settings.
Read the plan labels carefully. The current plans are Starter, Standard, and Premium, with calendar allowances of 1, 6, and 36 respectively. Standard adds packages and text reminders to Starter. A two-person practice needing separate appointment calendars should therefore cost the relevant multi-calendar plan. Acuity pricing.
An appointment calendar allowance is not the same quantity as external calendars connected to check conflicts. Write both requirements into the quote request so apparently similar numbers do not conceal a mismatch.
Keep a realistic Calendly baseline
Calendly Free lists one event type; Standard lists unlimited event types, while Teams adds round-robin scheduling. Compare your replacement with the plan that solves your actual need, not only with the limitations of the free tier. Calendly pricing.
If Acuity and Calendly remain the finalists, use the detailed Calendly vs Acuity workflow comparison. It examines intake, package redemption, deposits, and team behavior without expanding the shortlist again.
Check reminders and rescheduling
The exception after booking often provides the clearest decision. A client can understand a policy while the software still lets them do something the business did not intend.
| Decision point | Documented distinction or open check | What to inspect in your trial |
|---|---|---|
| Late cancellation or rescheduling | Calendly says its displayed cancellation policy does not enforce restrictions. Acuity provides scheduling limits for if and when clients can change appointments. | Attempt a change inside your chosen cutoff; record whether it is blocked or needs staff intervention. |
| Money after cancellation | Calendly and Acuity direct cash refunds to the payment processor. Acuity also says processor refunds are not reflected in its reports. | Reconcile the canceled booking with the processor transaction and your client record. |
| Reminder channel | Acuity places text reminders on Standard and above. Cal.com's plan page lists SMS notifications, but that alone does not establish country coverage, credits, or delivery. | Confirm plan, recipient eligibility, allowance, and the actual received message. |
| Change of employee | A candidate must satisfy your assignment rule after a reschedule as well as at first booking. | Make the original employee unavailable and inspect the new owner and notification. |
Sources for the documented rows: Calendly cancellation policy, Acuity scheduling limits, Calendly refunds, Acuity refunds, Acuity plans, and Cal.com plans.
Treat a reminder as verified only when it reaches the test recipient at the intended time. A saved template or enabled switch is not evidence of delivery. For Cal.com, verify the chosen plan's exact cancellation behavior during the trial; this review does not establish it from a dedicated help article.
Understand hosted and self-hosted options
Cal.com's April 15, 2026 technical announcement says its production code moved to a private repository and the public repository became Cal.diy. It describes Cal.diy as a community product for self-hosting, under the MIT license. Teams and organizations, routing forms, and the automated workflow engine were among the removed features. Cal.diy technical announcement.
Consequently, an older recommendation to “self-host Cal.com for the same team features” needs to be checked against the current product. This guide does not treat Cal.diy as a free equivalent of hosted Cal.com Teams. It also does not assess later community extensions or promise compatibility with a particular deployment.
If self-hosting is essential, name the person responsible for installation, upgrades, calendar credentials, backups, transactional email, and service recovery. Budget that work before comparing subscription totals. A license without a purchase charge does not establish a zero operating cost.
Free Calendly alternatives: define what must remain free
Hosted Cal.com's individual allowance can be relevant if one person needs several event types and calendars. That does not answer the cost of team assignment, payment processing, messaging usage, or technical maintenance. Keep free-plan research within the same workflow comparison rather than assuming a separate “free” shortlist solves a different problem.
Use the software cost checklist to record the billing term, number of users or appointment calendars, required integrations, taxes, and payment charges. This guide deliberately does not present a price quote without those inputs.
Try the complete client booking journey
Use the same sample services and availability in each candidate. The following is a proposed trial plan, not a list of results we obtained.
| Scenario | Set up | Pass condition |
|---|---|---|
| Introductory call | Two event types, a busy period in each connected calendar, and a visitor in another time zone | The conflict is unavailable and the confirmation describes the intended instant in both local time zones. |
| Deposit appointment | One paid service, required intake, a deposit, and a clearly written change cutoff | The record distinguishes service price, amount collected, remaining balance, and whether the late change is allowed. |
| Shared enquiry | Two employees, different availability, and a stated assignment rule | The booking reaches an eligible person with the enquiry context; an absence and reschedule remain understandable. |
| Cancellation and payment | Cancel the paid booking and follow the documented refund process | Booking status, money movement, package credit if applicable, and any manual reconciliation are separately recorded. |
For payment checks, follow the product's supported testing procedure and the processor's rules. Do not assume a sandbox or a fully discounted booking exercises the real charge-and-refund path. Confirm any fees before authorizing a live test transaction.
Record the configuration, observed result, required manual correction, and unresolved question for each row. A candidate passes when your essential conditions work on the plan you would buy. A feature count cannot compensate for a failed deposit record or an incorrectly assigned client.
Before switching, inventory old links in signatures, proposals, website buttons, and automated messages. Keep a plan for managing appointments already booked through the old system. If booking information must feed a broader client relationship, the consultant CRM guide helps define who owns the follow-up after the calendar invitation arrives.
