Calendly is the default scheduling tool for a reason. It is polished, it works, and the brand is everywhere. The catch is that the free plan caps you at 1 event type and 1 connected calendar, and the moment your availability is split across Google Calendar and Outlook, the free plan stops being enough.
This guide compares the most popular free Calendly alternatives on the criteria that actually matter for solo professionals and small teams: real availability, calendar sync, branding, custom questions, and total cost. It is meant to help you pick the right tool whether you stay free forever or upgrade later. For a deeper look at how sync and booking features overlap, see our free vs. paid calendar sync apps breakdown.
What most people actually need from a scheduling tool
Before comparing features, it helps to list the criteria that drive a real scheduling decision. Most people evaluating a Calendly replacement want a tool that:
- Shows real availability across every calendar the user actually uses, not just the one the tool is connected to.
- Is free or low-cost, with a clear upgrade path that does not gate the basics.
- Syncs events back to a real calendar so the host and the booker both have a record they trust.
- Supports branding and custom questions so the page can carry the host's identity and collect useful context.
- Does not require a credit card to start, and ideally does not require a sales call to upgrade.
- Handles cancellations and reminders automatically, without a separate workflow.
The table below scores the most popular alternatives against these criteria. Pricing reflects publicly listed plans at the time of writing and may change.
The honest comparison
| Tool | Free plan | Paid plan | Google + Outlook sync | Best for |
|---|---|---|---|---|
| Calendly | 1 event type, 1 connected calendar | Paid tiers with more event types, routing, and integrations | Yes, separate accounts per provider | Sales teams that need routing, CRM integrations, and a polished booker experience |
| TidyCal | Limited free tier | One-time lifetime payment | Reads from one connected calendar | Solopreneurs who want a single payment instead of a subscription |
| SavvyCal | Limited trial | Per-seat monthly or annual | Reads from one connected calendar per user | Hosts who care about a beautiful booker experience and ranked availability |
| Cal.com | Free and open source, self-hosted | Cloud hosting available, paid tiers by feature | Yes, multiple providers per user | Developers and teams who want full control and self-hosting |
| Microsoft Bookings | Included with Microsoft 365 | Bundled with M365 plans | Outlook only | Teams that already live in Microsoft 365 and only need Outlook scheduling |
| Calendar FreeSync | 2 calendar connections, unlimited sync, no booking pages | Pro at $5.99/mo, up to 10 connections and 5 booking pages | Yes, cross-platform Google and Outlook, bidirectional | People whose availability is split across Google and Outlook and want booking in the same tool |
A few notes on the table. Calendly is the most polished option in the category and the right call if you need routing, collective events, or deep CRM integrations. Cal.com is the most flexible open source option, with the trade-off that you either run the infrastructure yourself or pay for cloud hosting. TidyCal and SavvyCal both deliver solid booking pages, but each reads availability from a single connected calendar. Microsoft Bookings is the easiest fit for an Outlook-only team. Calendar FreeSync is the only entry that combines calendar sync and booking in one product, which is the practical reason it shows up on a list of Calendly alternatives.
Where Calendar FreeSync fits
Calendar FreeSync is built for one specific situation: the host whose real availability is split across Google Calendar and Outlook. The booking page inherits the same availability surface that powers the rest of the app, so busy blocks from any connected account count toward availability automatically. This is the practical difference between a booking page tied to one calendar and a booking page tied to your full set of synced calendars.
Concretely, here is what you get with Calendar FreeSync Pro at $5.99 per month:
- Sync and booking in one tool. No second product to wire up and no second availability to maintain.
- Up to 5 booking pages per Pro account, each with its own URL, duration, location, custom question, avatar, logo, working hours, buffer time, minimum notice, and advance window.
- Real events on the destination calendar you choose, with the booker added as an attendee and an .ics file attached to the confirmation email.
- Self-serve cancellation for the booker, with the calendar event removed automatically when a booking is cancelled.
- 24-hour reminder emails, host notification, and 90-day booking data anonymization included.
- 7-day free trial on the Pro plan for new subscribers, no credit card to start the free plan.
Where a different tool might be a better fit
Calendar FreeSync is not the right fit for every team. If you need AI scheduling that finds slots across multiple attendees, you are better served by a tool with a dedicated AI engine. If you need routing forms that direct visitors to the right host based on a dropdown answer, Calendly or Cal.com will serve you better. If you need Salesforce or HubSpot integrations, those are the tools to evaluate first.
The honest summary is that Calendar FreeSync is the booking tool for the calendar-sync problem. If your real availability is split across Google and Outlook, and you already trust Calendar FreeSync to keep those calendars aligned, then adding a booking page on top of the same surface is a much smaller leap than adding a separate scheduling product on top of one calendar. For the tradeoffs and the design choices behind that, see our engineering post on why we built bookings on top of calendar sync.
How to switch
If you decide to try Calendar FreeSync, the migration is straightforward:
- Sign up free. No credit card required for the free plan.
- Connect both calendars (Google and Outlook) so the booking page has a useful picture of your availability.
- Create your first booking page from the dashboard, share the link, and keep your existing Calendly page live until you are ready to retire it.
Most users move their most-booked meeting type over first, run both links for a week, and retire the Calendly page once the new link has the same booking volume. The free plan covers the trial period, and the Pro trial starts when you upgrade.
FAQ
What is the best free Calendly alternative?+
For people whose availability is split between Google Calendar and Outlook, Calendar FreeSync Pro is a strong fit because it combines calendar sync and booking in one tool, and the Pro plan is one of the cheapest paid options. Cal.com is a good pick if you prefer open source and want to self-host. Microsoft Bookings is the easiest option if your whole team is already on Microsoft 365.
Which Calendly alternative syncs Google Calendar and Outlook?+
Cal.com and Calendar FreeSync both support reading and writing events to multiple calendar providers, including Google and Microsoft. TidyCal and SavvyCal read availability from one connected calendar each. Microsoft Bookings works with Outlook only and does not connect to Google Calendar.
Do I need a credit card to start?+
No. Calendar FreeSync, Cal.com (self-hosted), and Microsoft Bookings (with a Microsoft 365 subscription) all let you start without a card. Calendly and SavvyCal ask for a card to start a paid trial. TidyCal is a one-time payment, not a subscription.
Can I customize the booking page?+
Most alternatives support custom questions, branding, and confirmation emails. Calendar FreeSync supports per-page avatar and logo, custom question, location, timezone, working hours, buffer time, minimum notice, and advance booking window. The depth of customization varies by tool, and Calendly has the deepest routing and form features for sales teams.
Will my booking page update if my calendar changes?+
Yes. All the tools listed read live availability from the connected calendar, so any change to a busy block is reflected on the booking page. Calendar FreeSync additionally reads busy blocks from your other synced Google and Outlook calendars, so a meeting on any connected account blocks the booking page even if the booking page is tied to a different destination calendar.
Try Calendar FreeSync free, no card required
Connect Google Calendar and Outlook, run your first sync, and publish a booking page when you are ready. Pro is $5.99 per month after a 7-day free trial.
