Calendar Meeting Scheduler Free: Where the Limits Are

A free calendar meeting scheduler comes in one of two shapes. A booking link (Calendly, Cal.com, Google Calendar appointment schedules) lets other people pick a slot from your calendar. A group poll (When2meet, WhenIsGood, Rallly) lets several people mark when they are free so you can pick the time. If the meeting is one to one, start with a booking link. If you are coordinating a group, start with a poll. The rest of this page covers what each free plan actually includes, checked against the vendors' own pricing and help pages on October 18, 2026, and which limit tends to stop people first.

Booking link or group poll: decide this first

Most comparison pages list both kinds of tool side by side, which hides the fact that they solve different problems.

A booking link is connected to your calendar. It reads your busy time, offers the gaps, and writes the confirmed meeting straight into your calendar. The person booking needs nothing but a browser. This suits sales calls, client intro calls, office hours, interviews, and anything where one person is the host and the other picks a time.

A group poll is not connected to anyone's calendar in the basic case. The organiser proposes a set of times, each participant marks the ones that work, and the grid shows where the answers overlap. This suits a committee meeting, a family dinner, a study group, or a project kickoff with five people from three companies. Nobody's calendar is read, which is also why nobody's calendar is updated automatically at the end.

The practical test is simple. If you would otherwise send "here are three times that work for me", you want a booking link. If you would otherwise send "when is everyone free next week", you want a poll. Picking the wrong shape is the most common reason a free tool feels broken: a booking link cannot find a time that works for six people, and a poll cannot stop a stranger from taking your Tuesday afternoon.

Some tools now cover both. Calendly lists meeting polls on its pricing page, and Google Calendar has appointment schedules for booking. Even so, the free tiers are built around one shape, and the limits below follow from that.

What the free booking link plans include

Here is what the three most common free booking tools state on their own pages today.

	Calendly Free	Cal.com Individuals	Google appointment schedules
Price	Free	Free forever	Included with a personal Google Account
Event types or booking pages	1	Unlimited	1
Calendars checked for conflicts	1	Unlimited	Primary calendar; more needs a subscription
Automatic reminders	Paid tiers	Email and SMS notifications included	Paid subscriptions
Take payment	Paid tiers (Stripe, PayPal)	Stripe and PayPal included	Paid subscriptions
First paid step	10 dollars per seat per month, billed yearly	Teams, 12 dollars per user per month, billed yearly	Google One Premium or an eligible Workspace plan

Calendly's pricing page lists the Free plan as one event type, one calendar connection, one to one scheduling, a customizable booking page, and the browser extension. Standard, at 10 dollars per seat per month billed yearly, adds unlimited event types, up to six connected calendars, automations and reminders, and Stripe and PayPal payments.

Cal.com's pricing page describes Individuals as free forever for one user, with unlimited event types and calendars, email and SMS notifications, a mobile app, a browser extension, Stripe and PayPal payments, and a one click import of Calendly events. Its Teams plan is 12 dollars per user per month billed yearly, with a 14 day trial.

Google's own comparison page puts the free scope in one sentence:

With a personal Google Account or Workspace Business Starter plan, you can create a single booking page to let others schedule appointments on your calendar. Source: support.google.com

The same page lists the features that need an eligible subscription: more than one appointment schedule, automatic email reminders, checking availability across multiple calendars, accepting payments, email verification to prevent spam bookings, schedules on secondary calendars, and up to 20 co-hosts.

What the free group poll tools include

The poll tools are lighter, and two of them have no account at all.

When2meet opens straight onto a date grid. The organiser picks dates and a time range, shares the link, and each participant paints the hours they are free. There is no sign-up and no paid plan.

WhenIsGood works the same way and says so on its front page: click the grid for the times that are good for you, email the link, and visit the results page to see when everyone can make it. "No sign-up form. No password to choose."

Rallly's pricing page is more specific about limits. The free Hobby plan allows up to 3 open polls at a time, unlimited participants, and 30 day poll retention. A poll is deleted once all its dates are more than 30 days in the past and there has been no activity for 30 days. Pro, at 6 dollars per seat per month billed yearly, removes the open poll cap, keeps polls indefinitely, and adds email invites, participant email requirements, custom branding, and removal of the "Powered by Rallly" line.

The limit that matters with polls is not a feature cap but the last step. When the votes are in, someone still has to create the event, invite everyone, and attach the meeting link. A poll answers "when", and then the organiser does the calendar work by hand.

The cap that bites first: how many calendars are checked

Most people compare booking tools on the number of meeting types, because that number is printed in large type. The number that decides whether the link is safe to send is how many calendars the tool checks before it offers a slot.

If your commitments live on two calendars, say a work Google account and a personal one, and the scheduler only reads one, every slot it offers is partly a guess. The booking page will offer a Thursday afternoon that is already taken on the other calendar. The result is a double booking with someone outside your organisation, who now has to be asked to move.

On the free plans, Calendly connects one calendar and Google's free tier does not include checking across multiple calendars. Cal.com's free plan includes unlimited calendars, which is the clearest single reason to choose it if you keep work and personal life on separate accounts.

There is a free workaround for the others. Share the second calendar into the account the scheduler reads, at the "See only free/busy (hide details)" level, so the busy blocks appear without revealing what the events are. Then make sure that shared calendar is included in the conflict check. It is one more sharing setting to maintain, and it closes the gap.

Setting up a free Google appointment schedule

If you already live in Google Calendar, the free appointment schedule is the shortest path to a working link. Google's setup guide lists these steps on a computer:

1. Open Google Calendar in a web browser. Appointment schedules cannot be created in the Android or iPhone and iPad apps.
2. At the top left, click Create, then select Appointment schedule.
3. In the "Bookable appointment schedule" panel, add a title and choose the Appointment duration.
4. Under General availability, set the days and hours you accept bookings.
5. Under Scheduling window, set how far ahead people can book and the minimum lead time.
6. Under Booked appointment settings, add Buffer time and Maximum bookings per day if you need them.
7. Under Calendars, choose where bookings land and select Check calendars for availability.
8. Click Next, set up the booking form, and save.

One default catches people out. Google sets a 4 hour minimum lead time, so a booking page checked right after setup may show no slots for the rest of today. That is expected, and it is also a reasonable floor. Most people raise it rather than lower it.

The three booking settings above exist in Calendly and Cal.com too, under similar names. They decide whether a link protects your day or quietly fills it, and they cost nothing to set.

Reminders, payment, and the second host

After conflict checking, three more limits separate free from paid.

Reminders. A booking made three weeks out is easy to forget. Calendly puts automated reminders in Standard, and Google lists automatic email reminders as a subscription feature. Cal.com includes email and SMS notifications on the free plan. Without automated reminders, the work moves to you. At five bookings a month that is five short messages. At twenty or thirty, the time spent sending them is usually worth more than the monthly fee.

Payment. If the meeting itself is the product (a consultation, a lesson, a session), taking payment at the moment of booking removes a whole chase. Cal.com includes Stripe and PayPal on its free plan. Calendly includes them from Standard. Google lists accepting payments among the subscription features.

A second host. Every free plan here is built for one person. Calendly's round robin and team scheduling sit in Teams at 16 dollars per seat per month billed yearly. Cal.com's shared availability, round robin, and collective event types sit in its Teams plan. Google's co-hosts, up to 20 per schedule, are a subscription feature. If a colleague will share the link within a few months, price the team tier now rather than rebuilding later.

Spam is worth a mention. An open booking link accepts a booking from anyone who finds it. Google lists email verification for bookings as a subscription feature, and Rallly puts required participant emails in Pro. If the link will sit on a public website, budget for that protection.

Where a desktop calendar fits

A scheduler answers one question: when are you free. It does not check whether the day it just filled still works once travel and preparation are counted. Slots at nine, eleven, and two look fine on a booking page and can leave no continuous block long enough to finish anything. If the meetings are in different places, the gaps also have to hold travel, which a booking page does not model.

That half of the problem sits in the calendar app you look at every day. On a Mac, one option is a native calendar app made by the company that runs this site. Its free version has no time limit and covers events, natural language entry, travel time with time-to-leave alerts, and as many Google accounts as you connect. Its own booking page is a paid feature (4 dollars a month, 29 dollars a year, or 49 dollars once, with a 14 day trial). When publishing a link, private calendars can be counted as busy, so anything on them closes the slot without showing what the event is. How bookings and travel blocks work is laid out in the Guide, and the plan details are on the Buy page.

What to change first

Count the calendars that hold your real commitments. If there is more than one, pick a free plan that checks all of them, or share the others into the account your scheduler reads. Then set a buffer, a daily cap, and a minimum notice before the link goes anywhere. If the trouble is the shape of the day rather than the bookings, Caltimate works on that part.
