The Best Free Alternatives to Calendly
Calendly solved a real problem: the back-and-forth of finding a time to meet. Then it built a pricing model that charges per user per month for features like calendar sync, group events and routing that most free alternatives now include at no cost. The landscape has matured to the point where an open-source platform gives you the full Calendly feature set for free, two of the largest productivity suites bundle appointment scheduling into plans you may already pay for, and a one-time purchase tool makes the subscription model look like a tax on the disorganised. The right pick depends on how many meetings you schedule, whether your calendar lives in Google or Microsoft, and whether you need routing logic that sends different people to different slots.

- If you want the closest open-source replacement with more features on the free tier than Calendly gives you on the paid one, Cal.com is the answer: unlimited event types, routing forms, team scheduling and self-hosting, all free.
- If your organisation already pays for Microsoft 365, you already have Microsoft Bookings: a full appointment scheduler with group events, staff management and Teams integration at no extra cost.
- If you live in Google Calendar and just need a personal booking page, Google Calendar appointment schedules are free, built in, and cover the core one-to-one scheduling use case without leaving the tab you already have open.
- If you hate subscriptions on principle, TidyCal costs a single flat fee and gives you unlimited booking types, group events, custom reminders and payment integration with no recurring charge.
- No free alternative replicates Calendly's routed forms that mix qualification questions with conditional slot logic and team round-robin simultaneously. Several tools do two of the three for free; the full trifecta remains Calendly's paid differentiator.
Scheduling a meeting should be the easiest part of anyone’s day. In practice it spawns a three-email thread that ends with a Zoom link sent two minutes late. Calendly removed that friction by letting one person publish their available times and the other person pick one, and in doing so created a category.
The product earned its place. The pricing model that came with it — charging per user per month for features like more than one event type, calendar sync across multiple calendars, and routing that sends different people to different time slots — has not aged as well. The free alternatives have closed the gap, and in at least one case an open-source platform now gives away for free the features Calendly charges for. The question is not whether a free scheduler exists but which one matches how you actually work.
What Calendly Does, and What You Actually Need
Strip away the interface polish and Calendly solves four problems. It publishes a subset of your availability without exposing your full calendar. It lets other people claim a slot without asking you. It writes the booking to both calendars. And it sends a reminder so nobody forgets.
Most people use about forty percent of what their scheduling tool can do. They need a personal booking link, one or two event types — a thirty-minute call and a fifteen-minute call, perhaps — automatic calendar blocking, and email confirmations. Everything beyond that — routing forms, round-robin team distribution, payment collection, CRM sync — matters to a fraction of users. The free alternatives split along exactly this line: some cover the core forty percent perfectly and stop there, while others push deep into the power-user features without asking for money.
The Seven Best Free Alternatives
Cal.com: The Open-Source Calendly Replacement
Cal.com is the most direct answer to the question “what is a free alternative to Calendly?” because it was built to be exactly that. It is open-source, can be self-hosted on your own server, and offers a cloud-hosted free tier that covers individuals with no meaningful cap: unlimited event types, unlimited bookings, calendar sync with Google and Outlook, and routing forms that let you qualify leads before they pick a time.
The feature that matters most: routing forms. You can ask custom questions — “what is this meeting about,” “how large is your team” — and send people to different calendars or event types based on their answers. Calendly charges for this. Cal.com gives it away on the free tier. The self-hosted version adds no additional limits: no per-user charge, no cap on team members, and full control over where the data lives. For a consultancy that books discovery calls and wants to triage by company size before anyone looks at a calendar, this routing alone makes Cal.com the strongest free option.
The trade-off is that self-hosting requires a server and the willingness to maintain it. The cloud free tier is generous but adds a small Cal.com branding element, and the interface, while clean, does not feel quite as polished as the product it competes with. For most users the difference is cosmetic.
Microsoft Bookings: You May Already Be Paying for It
If your organisation has a Microsoft 365 Business Standard, Business Premium, or Enterprise plan, Microsoft Bookings is already included. It is not a stripped-down scheduling widget bolted onto Outlook; it is a full appointment booking system with a public-facing page, staff assignment, group appointments, buffer time between meetings, custom email confirmations and automatic Teams links.
The integration is the differentiator. Bookings reads availability directly from Outlook and writes appointments back without a third-party sync layer that can lag or break. Staff can set their own working hours, and the booking page only shows slots when everyone is free. For a team that already runs on Microsoft, this eliminates the two weakest links in most scheduling setups: the calendar sync and the video link.
The free tier within Microsoft 365 covers the core workflow without limits on bookings, event types or staff. What it does not do: payment collection at booking time, routing logic that sends different people to different calendars based on answers to questions, or a polished embed that matches Calendly’s. It is a scheduling tool built for organisations that already live in Outlook, and within that context it is hard to beat.
Google Calendar Appointment Schedules: Built In, Good Enough
Google Calendar quietly replaced its older appointment slots feature with appointment schedules, and the new version is a genuine booking page. You create a schedule — say, thirty-minute calls available on Tuesdays and Thursdays between ten and four — and Google generates a public link. People who open it see your available slots in their time zone, pick one, and the event appears on both calendars with a Google Meet link attached.
The strength is that there is nothing to install, nothing to sign up for, and nothing to sync. If you already use Google Calendar, the appointment schedule lives inside the same tab, respects your existing working hours and blocked time, and sends confirmations through the same email infrastructure you already trust. For a freelancer who just needs a way for clients to book thirty-minute calls without the email ping-pong, Google Calendar does the job.
The limits are real. Appointment schedules only support one-to-one booking — no group events where multiple people claim the same slot. There is no routing, no payment collection, and no way to ask custom questions before someone picks a time. The booking page is functional but sparse, with no branding options beyond the colour of your Google account avatar. If your scheduling needs stop at “pick a time, we both show up,” it works. If you need more, you need one of the other tools on this list.
SavvyCal: The One That Feels Human
SavvyCal’s free tier covers one calendar connection and one booking link, but what it does with that single link is different from the rest. Instead of showing a grid of available times and hoping the other person picks one, SavvyCal lets the recipient overlay their own calendar on top of yours — the greyed-out availability you usually keep to yourself, visible as a read-only layer so they can pick a time that works for both of you without the back-and-forth.
This single feature changes how the interaction feels. Most scheduling links communicate “here is when I am free, fit into it.” SavvyCal communicates “here is when I am free, show me when you are too, and let us find the overlap.” For client-facing work where the relationship matters — consulting, coaching, freelance design — that softer framing is worth more than an extra event type.
The free tier also limits you to one event type and does not include routing or group events. SavvyCal’s paid plan unlocks those, and the pricing is comparable to Calendly’s. The free version is best understood as a single booking link with better social dynamics, not a full Calendly replacement.
TidyCal: Pay Once, Use Forever
TidyCal is the answer for people who object to the subscription model on principle. It costs a one-time fee — not a monthly charge — and after that single payment you have unlimited booking types, unlimited bookings, group events, custom email reminders, payment integration via Stripe and PayPal, and calendar sync with Google, Outlook and Apple.
The interface is simpler than Calendly’s and feels less polished than Cal.com’s, but the feature list at the one-time price is difficult to argue with. For a small business that schedules client calls, takes payments at booking time, and wants to stop seeing “Calendly” on the credit card statement every month, TidyCal eliminates the recurring cost without eliminating the functionality.
The trade-off is that TidyCal does not offer routing forms, round-robin team distribution across more than a handful of people, or the deep CRM integrations that Calendly and Cal.com provide. It is a scheduling tool for individuals and small teams who value simplicity and a single payment over enterprise features they would not use anyway.
Zoho Bookings: The One for Zoho Users
Zoho Bookings is part of the Zoho ecosystem, and if your business already uses Zoho CRM, Zoho Mail or Zoho Calendar, it is the obvious choice. The free tier covers one user, one booking page, and calendar sync. The real value is the integration: when someone books through Zoho Bookings, the contact appears in Zoho CRM automatically, the appointment syncs to Zoho Calendar, and the confirmation email comes from Zoho Mail. No middleware, no Zapier, no webhook that breaks when someone changes a field name.
For everyone not already inside the Zoho universe, the free tier is fine but unremarkable — it does what the other tools do without the ecosystem lock-in that makes it shine. Zoho’s approach to free tiers across its product line is to give away enough to be useful and reserve the deep value for those who adopt the full suite. Zoho Bookings fits that pattern: strong if you are all-in on Zoho, average if you are not.
SimplyMeet.me: The Dark Horse
SimplyMeet.me, from the company behind the time-tracking tool TimeCamp, offers a free tier with one booking page, calendar sync with Google and Outlook, custom availability rules, buffer time between meetings, and automatic time zone detection. The interface is clean and the booking flow is straightforward — pick a time, fill in a name and email, and the meeting appears.
It does not have routing forms, group events or payment collection on the free tier, and the customisation options are thinner than Cal.com’s or even Calendly’s own free tier. Its advantage is that it places no limit on how many meetings you can book and does not degrade the core booking experience for the sake of upselling. For someone who wants a single booking link that works, without complexity and without a monthly charge, SimplyMeet.me is the most straightforward option that nobody talks about.

What the Free Tools Do Not Give You
No free scheduling tool matches Calendly’s routing-plus-round-robin combination. Cal.com does routing forms for free and does round-robin team distribution for free, but does them as separate features — the conditional logic that changes the calendar based on how someone answers a question does not combine with the round-robin that distributes bookings across a team in the same workflow. Calendly’s paid tier does both together, and for sales teams that need to qualify a lead by company size before assigning them to the right rep, that combination is worth paying for.
The integrations gap is smaller than it used to be. Cal.com and Zoho Bookings connect natively to their respective ecosystems; Microsoft Bookings and Google Calendar eliminate the need for a connector by living inside the platform. The gap that remains is the long tail — the native Salesforce integration, the pre-built HubSpot connector — the kind Slack users recognise from their own integration marketplace — and the Stripe payment link that embeds directly into the booking page. Several free tools touch one or two of these; none touches all of them.
The user experience gap is real but shrinking. Calendly has spent years polishing the booking flow, the confirmation screen, the reminder emails and the reschedule interface until they feel frictionless. The free tools range from Cal.com’s clean and competent design to Google Calendar’s functional but bare-bones booking page. A recipient who clicks a Google Calendar appointment link will figure it out. A recipient who clicks a Cal.com link will barely notice they are not on Calendly. A recipient who clicks a SimplyMeet.me link may pause for a second before continuing. The difference is small and getting smaller, but it exists.
How to Pick
Start with where your calendar lives. If your organisation pays for Microsoft 365 Business Standard or above, try Microsoft Bookings first — you are already paying for it, it reads your Outlook availability directly, and it adds nothing to install or sync. If you use Google Workspace or a personal Google account, try Google Calendar appointment schedules for the same reason: zero setup, zero cost, and it may be all you need.
If the built-in tools do not cover your workflow — you need routing forms, group events, or more than one event type — the decision splits. For most people, Cal.com is the strongest all-round free alternative: its free tier covers what Calendly’s paid tier does on routing, event types and team scheduling, and the self-hosting option removes every remaining cap. For people who hate subscriptions, TidyCal’s one-time payment eliminates the recurring charge forever. For those who want a single booking link with better social dynamics than a standard scheduling grid, SavvyCal’s overlay feature is unique and worth the trade-off of being limited to one event type.
If your team uses Zoho, use Zoho Bookings — the CRM integration alone justifies it, and the free tier covers the basics. If you just want a booking link that works and you never want to think about it again, SimplyMeet.me is the simplest path that nobody else mentions.
The scheduling tool you already have access to, even if it is Google Calendar, is better than the one you pay for and never set up. The gap between free and paid has narrowed to a handful of enterprise features most people will never need, and the answer to “which free alternative” is usually the one that is already on your screen.
Frequently asked questions
What is the best free alternative to Calendly?
The honest answer depends on where your calendar already lives. If your organisation uses Microsoft 365, Microsoft Bookings is already included in most business plans and covers the full scheduling workflow — public booking page, staff assignments, group events, email reminders and Teams integration — without installing anything. If you use Google Workspace or a personal Gmail account, Google Calendar appointment schedules handle one-to-one booking and slot the meeting directly into your calendar. If you want an independent tool that is not tied to any ecosystem, Cal.com offers the most generous free tier with unlimited event types, routing forms and self-hosting, matching features Calendly reserves for its paid plans. And if you want to stop paying monthly altogether, TidyCal's one-time purchase gives you unlimited booking types and group events with no subscription.
Is there a completely free scheduling tool with no limits?
Yes, Cal.com. The open-source version is free to self-host on your own server with no cap on event types, bookings, team members or integrations. The Cal.com cloud free tier also covers unlimited event types and bookings for individuals, with the paid plans unlocking team features and routing. Microsoft Bookings is effectively unlimited for organisations that already have a qualifying Microsoft 365 plan — there is no per-booking charge and no cap on staff members who can be assigned to appointments. The trade-off with both is that truly unlimited free scheduling either asks you to run the software yourself or depends on a subscription you already pay for elsewhere.
Can I replace Calendly with Google Calendar?
Yes, if your needs are straightforward. Google Calendar's appointment schedules — the feature that replaced the older appointment slots — gives you a personal booking page where people can pick from the times you make available. It blocks the time on your calendar automatically, sends email confirmations, and works with the Google Meet integration you already have. What it does not do: routed forms that send different people to different calendars, group events where one slot books multiple attendees, or payment collection at booking time. If your workflow is 'someone picks a time, we both show up,' Google Calendar does the job without leaving your existing tab. If you need routing logic or group bookings, Cal.com or Microsoft Bookings fills the gap.
Why would anyone pay for Calendly if free tools exist?
Calendly's paid plans buy three things the free alternatives have not matched in one package. The first is routing logic: forms that dynamically change which calendar someone sees based on how they answer qualification questions, paired with round-robin distribution across a team. Several free tools do one or the other; none does both together with the polish Calendly has refined over a decade. The second is the integrations marketplace: native two-way sync with Salesforce, HubSpot, Zoom, Stripe and dozens of others, pre-built and maintained. The third is the network effect: Calendly links are embedded in enough email signatures and websites that recipients recognise the interface and know what to do without thinking. If none of those three apply to your workflow, a free alternative gives you the same scheduling outcome for no money.
Which free scheduling tool handles group events best?
Cal.com's free tier supports collective events — where multiple attendees book the same slot — and round-robin distribution across team members, both features that Calendly puts behind its paid plans. Microsoft Bookings also handles group appointments and staff assignment at no extra cost within qualifying Microsoft 365 plans. For a one-time purchase, TidyCal supports group events and lets you set a maximum attendee count per slot. If group scheduling is central to your workflow and you do not want to pay monthly, Cal.com is the strongest free option; if your organisation already has Microsoft 365, Bookings is the path of least resistance.
