Best Free Scheduling Software in 2026: Booking Links, Appointments and Open-Source Options

Free scheduling software falls into three jobs: booking links for one-to-one meetings, appointment booking for service businesses, and polls that find a time for a group. Calendly, zcal and TidyCal cover booking links, Zoho Bookings, Setmore and Square Appointments cover appointments, and Rallly covers polls. Cal.diy and Easy!Appointments are open-source choices you host yourself.

This guide covers appointment and meeting scheduling, not staff rostering. Each pick notes what its free plan includes and where it stops. The live table below shows pricing model, self-hosting and licence, and the picks after it are grouped by job.

How we picked the best free scheduling software

Enlisted kept tools whose core job is letting other people book time with you or vote on a time: booking pages, availability rules, calendar sync and reminders. For hosted products, the directory records whether a free plan exists, taken from each vendor's pricing page. For open-source projects, it checks the licence, self-hosting support and recent GitHub activity, shown on the live cards. Shift-scheduling tools for employees, such as Deputy, When I Work and Homebase, are a different job and are not covered here. The method is in how Enlisted ranks tools, and the scheduling category lists more.

Which kind of scheduling tool do you need?

A booking link tool lets someone pick from your open calendar slots. An appointment tool adds services, staff, payments and reminders for a business that sells time. A poll tool asks a group to vote on times, and the organizer picks the winner. Many products overlap, so choose by the job you do most often. If you also want calendar and time planning, the best productivity apps guide covers Google Calendar and related tools.

Best free scheduling software for booking links

These tools share a link where invitees see your availability and pick a slot, which then lands on your calendar.

1. Calendly: best-known booking link tool with a free plan for one event type

Calendly is a meeting scheduling tool that lets people book time from your shared availability. You connect a calendar, set availability and share a link, and the booking is added to both calendars. The vendor now positions it around the work surrounding meetings, with payments, contacts, an AI notetaker and a mobile app and browser extension.

Calendly's pricing page says the free plan includes one event type, one calendar connection and one-on-one scheduling with a customizable booking page. Unlimited event types, automations and payments start on a paid plan, round-robin and team scheduling are on the Teams plan, and removing Calendly branding needs a paid plan. See the Calendly page and its alternatives.

• Best for: individuals who need one reliable meeting link.
• Watch out for: the free plan is limited to a single event type, and it is closed source with no self-hosted version.

2. zcal: best free booking pages with unlimited links and calendars

zcal is a scheduling service with brandable booking pages, round-robin and collective scheduling, event polls and a free tier. The vendor highlights custom fonts, colors and media on booking forms, plus unlimited links and unlimited calendars on the free plan, and presents itself as a free alternative to Calendly.

For teams, collective scheduling offers only times that work for every co-host, and round robin spreads meetings among team members. Paid options are on the vendor's pricing page. See the zcal entry.

• Best for: freelancers who want branded booking pages without paying, and small teams who need round robin.
• Watch out for: Enlisted's data does not list the paid plans' details, so confirm what each tier adds on zcal's pricing page.

3. TidyCal: best low-cost booking page with a lifetime option

TidyCal is a simple booking page and calendar tool that syncs calendars, accepts payments for paid sessions and generates meeting links automatically. The vendor says a booking page can be ready in minutes, and you can publish a simple booking website for services.

Enlisted lists a free plan with unlimited bookings, plus one-time lifetime plans and a monthly Pro plan. See the TidyCal listing.

• Best for: coaches, freelancers and solo professionals who want to avoid ongoing subscription fees.
• Watch out for: it is built for individuals and small businesses, so check team features such as round robin before relying on it for a team.

4. SavvyCal: best for making it easy for the invitee to pick a time

SavvyCal is scheduling software whose links show invitees a week view and let them overlay their own calendar, so both sides can spot good times at a glance. Links can use custom colors, a banner image and an avatar, and can sit on a custom domain.

It is on this list as the paid option for people who care about the invitee's experience. Enlisted lists no free plan, only a trial and a money-back guarantee. See the SavvyCal page.

• Best for: consultants and sales reps who schedule with busy clients and want a branded link.
• Watch out for: there is no free plan, so it does not meet the "free" test beyond a trial.

Best free scheduling software for appointments and service businesses

Businesses that sell time need services, staff, reminders and payments, not just a link.

5. Zoho Bookings: best for service businesses and teams that already use Zoho

Zoho Bookings is appointment scheduling software from Zoho that lets customers pick a time slot from a booking page, fill in a short form and receive confirmation and automated reminders. It syncs calendars, collects payments and offers AI-assisted scheduling workflows.

Enlisted lists a free plan for one user, paid Basic and Premium tiers per user, a Flex tier by quote and a trial. See the Zoho Bookings page.

• Best for: consultants and service businesses, especially those already in the Zoho ecosystem.
• Watch out for: the free plan covers a single user, and it is closed source.

6. Setmore: best free plan for a small team of service providers

Setmore is online appointment scheduling software with a booking page, calendar, reminders, an embeddable website widget and class booking. It adds payments through Stripe and Square, staff scheduling, calendar sync, a live receptionist service and mobile apps, with integrations such as Zoom, Google Calendar and WordPress.

Its free plan is aimed at small teams, with a paid Pro plan per user. Industry pages cover barbers, trainers, photographers and legal practices. See the Setmore entry.

• Best for: barbers, trainers and independent practitioners who need reminders and a booking widget at no cost.
• Watch out for: the free plan is limited to a few users, so larger teams move to the paid per-user plan.

7. SimplyBook.me: best free plan for businesses that want a branded booking website

SimplyBook.me is an online booking system for businesses that take appointments, such as salons, clinics, fitness studios, driving instructors and event organizers. Clients book at any hour, get reminders and can pay online, using either a hosted booking website or an embedded widget.

Its features include calendar sync, Facebook and Instagram bookings, marketing tools and AI voice booking. Enlisted lists a free plan limited by a number of bookings, paid plans with no per-user charge and a trial. See the SimplyBook.me page.

• Best for: service businesses that want a booking site, reminders and payments.
• Watch out for: the free plan is capped by bookings, so a busy business will outgrow it.

8. Square Appointments: best for salons and service providers on Square

Square Appointments is booking software from Square that combines online scheduling, client reminders and payments, with real-time sync. It sits alongside Square's payment acceptance, staff scheduling and customer retention tools, and its site is organized around business types such as beauty and wellness.

Square Free has no monthly subscription fee, but card processing fees are charged separately, and paid Plus and Premium plans are priced per location with trials. See the Square Appointments entry.

• Best for: salons, barbers and independent providers who already take payments with Square.
• Watch out for: it is tied to the Square platform and its processing fees.

Best free tools for scheduling a group meeting

Booking links give invitees your availability. Polls do the reverse: the organizer proposes options and everyone votes.

9. Doodle: best known hosted meeting poll

Doodle is a hosted meeting poll and scheduling tool that helps groups find times that work for all attendees. An organizer proposes several possible times, participants say which ones suit them and the group settles on the best fit, which avoids long email threads about availability.

Enlisted lists a free tier and notes that calendar integrations, booking pages and plan structure should be confirmed on Doodle's own site. See the Doodle page.

• Best for: coordinating a meeting or event across a group of people.
• Watch out for: it is hosted only, and details of the free tier are best checked with the vendor.

10. Rallly: best open-source tool for group scheduling polls

Rallly is an open-source scheduling tool where you create a poll with date options, share a link and let participants vote on when they are available. Participants do not need an account, an availability grid shows everyone's responses at a glance, and comments let people discuss details on the poll.

It is AGPL-3.0, has a hosted version and can be self-hosted with Docker. Enlisted lists a free Hobby plan with unlimited polls and participants, and a paid Pro plan per seat that adds branding, email invites and API access. See the Rallly listing.

• Best for: teams and friend groups that want a free poll and the option to self-host.
• Watch out for: it finds a time for a group but is not a personal booking page.

Best open-source scheduling software

Open-source schedulers are free to run but not free to operate: you provide a server, keep it updated and set up email for notifications.

11. Cal.diy: best self-hosted MIT-licensed scheduling platform

Cal.diy is the community edition of Cal.com: an MIT-licensed, self-hosted scheduling platform with the enterprise code removed, so the whole codebase is MIT with no proprietary edition. It is built with TypeScript, Next.js, tRPC and PostgreSQL, needs no license key or Cal.com account, and drops enterprise features such as Teams, Organizations, Insights, Workflows and SSO/SAML.

There is no hosted service for Cal.diy, so you run it on your own infrastructure, and the project describes it as intended for personal use. If you want the hosted product, Cal.com says it is open source and offers a free plan for individuals with unlimited event types, calendar syncing and Stripe payments, along with a self-hosting option with Docker. Cal.com itself is not in the Enlisted catalogue. See the Cal.diy page.

• Best for: developers and privacy-minded individuals who want a personal booking page on their own server.
• Watch out for: there is no hosted version, and the team and organization features have been removed.

12. Easy!Appointments: best self-hosted appointment scheduler for a small business site

Easy!Appointments is a self-hosted appointment scheduling system built with PHP and MySQL, released under GPL-3.0. It manages appointments and customers, organizes services and providers, sets working plans and booking rules, syncs with Google Calendar, sends email notifications and has a multi-language interface and a REST API.

It can be integrated with an existing website and database, which suits a business that wants booking on its own domain. The project offers premium features and services separately. See the Easy!Appointments entry.

• Best for: small businesses with web hosting that want an appointment scheduler they control.
• Watch out for: you host and maintain it, and the catalogue lists no hosted version.

Thunderbird Appointment is another open-source option under MPL-2.0 that lets people book time through a shareable page. It runs from Docker, and a hosted service is offered.

What does free scheduling software actually include?

Free plans are designed to be useful but limited. Typical limits in this guide:

• Calendly: one event type and one calendar connection on the free plan.
• zcal: unlimited links and calendars advertised on the free plan.
• TidyCal: unlimited bookings on the free plan.
• Zoho Bookings: free for one user.
• Setmore and Square Appointments: free plans aimed at small teams and solo providers, with processing fees on Square.
• SimplyBook.me: free up to a capped number of bookings.
• Rallly: unlimited polls and participants.
• Open source: Cal.diy and Easy!Appointments have no licence fee, but you pay for hosting.

Not free: SavvyCal and Acuity Scheduling offer trials rather than free plans, and Microsoft Bookings is included with Microsoft 365 business plans. Before choosing, check which features a free plan removes: branding, payments, automations and team scheduling are the usual ones.

How to choose the best free scheduling software

Match the tool to the job, then test the free plan with your real workflow for a week. If a free limit blocks you, such as one event type or a booking cap, compare paid prices only for the one or two tools that fit, and consider the Calendly alternatives list for the rest.
