Calendly alternative: Replio's free booking calendar

Want a free booking calendar that also takes appointments straight inside a chat — not just from a link people have to click? Replio's booking calendar is free on every plan, with event types, team routing and reminders like Calendly, plus AI booking inside WhatsApp, Instagram and Telegram.

Calendly is the best-known scheduling tool: share a link, the other person picks a free slot, done. Replio's booking calendar does the same job — event types, host availability, buffers, reminders, a cancel/reschedule link for the guest — and adds something a standalone booking page can't: the AI already answering your customers on WhatsApp, Instagram and Telegram can take the booking right there in the conversation, so a customer who's already messaging you never has to leave the chat to find a free slot.

A booking link vs a booking conversation

Calendly is excellent at what it does: send a link, the other person books a slot, it lands on both calendars. If your customers are used to clicking a scheduling link, it's a proven, polished tool.

Replio starts from a different moment: a customer already messaging your business on WhatsApp or Instagram asking "can I book a table for Friday?" or "when's your next slot?". Sending them off to a separate booking page loses momentum — some won't click through, others will book somewhere else in the meantime. Replio's AI can instead collect the service, date, time, name and contact details right inside that same chat and confirm the appointment on the spot, 24/7, in the customer's own language. You can still share a standalone booking link the same way you'd share a Calendly link — it's just not the only way in.

What you get with Replio's booking calendar

Event types with their own duration, description, colour and location (in person, a call, a video link) — set up as many as you need.
Multiple hosts, each with their own weekly availability windows and timezone.
Team event types that route round-robin across a group of hosts, for businesses where any of a few people can take the meeting.
Buffers and booking limits: a gap kept before/after every meeting, a minimum-notice window so people can't book five minutes from now, and a maximum booking horizon.
Conversational booking: the AI takes bookings directly inside WhatsApp, Instagram, Messenger and Telegram chat, with no separate page required.
A shareable link too, replio.live/book/<your-page>, for anywhere you'd normally drop a Calendly link.
Guest reminders and a self-serve cancel/reschedule link, plus a downloadable calendar (.ics) invite for the guest's own calendar.
Free on every plan, including the free tier (a custom page name is an optional paid add-on), with an easy path to full AI support across every channel when you're ready.

How to set up your booking calendar

Start a free Replio account.
Open the Booking section and add a host — your name, timezone and weekly availability.
Create an event type: title, duration, location and any buffer or notice rules.
Share your replio.live/book/ link anywhere, and/or connect WhatsApp, Instagram or Telegram so the AI can offer and confirm bookings in chat.
Get reminded before each appointment, and mark it completed or no-show afterwards.

When Calendly might fit better

If live two-way sync with your Google or Outlook calendar (so it auto-blocks time you're already busy) is a hard requirement, or you need Calendly's larger library of integrations and workflow automations, Calendly's ecosystem is more mature today. Replio's booking calendar wins when you want scheduling that's free on every plan and can also be booked conversationally by a customer who's already messaging your business — not just from a link.

Frequently asked questions

What is the best free Calendly alternative?

Replio's booking calendar is a free Calendly alternative included on every plan, including the free tier. It adds team/round-robin routing, event types, buffers and reminders like Calendly, plus the ability to take bookings directly inside a WhatsApp, Instagram or Telegram chat.

Is Replio's booking calendar really free?

Yes. The booking calendar is free on every Replio plan, including the free tier (a custom booking-page name/alias is an optional paid add-on). It's part of Replio, an AI customer support platform, so you can add AI support on WhatsApp, Instagram, Messenger and Telegram from the same account.

Can customers book an appointment directly inside a WhatsApp or Instagram chat?

Yes — this is the main way Replio differs from Calendly. Replio's AI can collect the service, date, time, name and contact details right inside the conversation and confirm the booking, 24/7, without sending the customer to a separate page. You can also share a standalone replio.live/book/ link the same way you'd share a Calendly link.

Does Replio support team scheduling and round-robin booking?

Yes. You can add multiple hosts, set each host's own weekly availability and timezone, and create a team event type that routes bookings round-robin across the group, similar to Calendly's team routing.

Does Replio's booking calendar sync with Google Calendar or Outlook?

Not today — availability is set as weekly recurring windows per host rather than pulled live from a connected Google or Outlook calendar. Confirmed bookings do generate a downloadable calendar (.ics) invite for the guest to add to their own calendar. If live two-way calendar sync to auto-block busy time is a must-have, that is one place Calendly is currently ahead.

What do guests get when they book with Replio?

A confirmed appointment with a downloadable calendar invite, and a link to cancel or reschedule without contacting the business directly. The business gets a reminder before the appointment and can mark a booking as completed or no-show.

Can I limit how far ahead people can book, or require notice before a meeting?

Yes. Each event type has a minimum-notice window (so people can't book in the next few minutes) and a maximum booking horizon (how many days ahead the calendar is open), plus an optional buffer kept before and after every meeting.
