Best Free Scheduling Tools in 2026 (That Actually Work)
Half the tools marketed as “free” are really 14-day trials with a countdown timer. This list only includes tools with genuinely usable free tiers — not demos, not trials, not “free if you never actually schedule anything.”
The first six entries are all Carly’s free scheduling tools. Each one solves a different scheduling job — booking pages, group polls, time-zone planning, email-to-calendar, calendar sync, and a CLI/MCP server. The rest of the list is the best of what’s outside Carly.
1. Carly Booking Page
A Calendly-style booking page that takes under a minute to set up. Connect Google or Outlook, set your availability, share the link. The free tier covers unlimited bookings, multiple meeting types, and round-robin across calendars.
Best for: Anyone who needs a booking link today and doesn’t want to think about pricing tiers or upgrade nags.
2. Carly Group Polls
Drop a poll into any chat to find a time that works for everyone. Participants don’t need an account — they click the link, mark when they’re free, and the overlap surfaces automatically. Drag-select grids, time-zone aware, and free with no participant cap.
Best for: Coordinating team meetings, dinners, or anything where five people can’t agree on Tuesday vs. Thursday.
3. Carly Email-to-Calendar
Forward any event description — flight confirmations, “let’s grab coffee Thursday at 3,” conference invites, even screenshots of posters or schedules — to add@usecarly.com and get back an .ics invite. Vision processing means it reads photos and images too, not just text. No signup, no install, works from any inbox.
Best for: The 30 emails a week that contain dates and times but somehow not actual calendar invites.
4. Carly Time Zone Meeting Planner
Compare working hours across multiple time zones and find the overlap window. Pick cities, see everyone’s local time on a single grid, and lock in a slot that doesn’t ask anyone to wake up at 4am. Free, no signup.
Best for: Distributed teams scheduling across more than two time zones.
5. Carly Calendar Sync
Mirror events between your personal and work calendars without leaking event details. Block busy time on your work calendar so colleagues can’t double-book your dentist appointment, but keep the title private. Rules and presets handle the edge cases (recurring events, all-day blocks, OOO).
Best for: Anyone juggling more than one calendar who’s tired of meetings landing on top of personal commitments.
6. Carly MCP
Manage booking pages, availability, and bookings from your terminal — or hand the same tools to Claude, Cursor, or any MCP-compatible agent. Free CLI, free MCP server. Useful if you’d rather automate scheduling than click through a UI.
Best for: Developers and power users who want scheduling primitives they can script against.
7. Cal.com
Open-source scheduling platform with the most generous free tier of any traditional booking page tool. Unlimited event types, unlimited bookings, multiple calendar connections, workflows, routing forms, and webhooks — all free for a single user (with Cal.com branding). You can self-host the entire platform for full data control or use the hosted version.
Best for: Solo users who want a fully featured booking page without paying. Developers who want to self-host or customize their scheduling infrastructure.
8. Calendly (Free Tier)
The most recognized name in scheduling, but the free plan is restrictive: one event type, one calendar connection, basic Zoom/Google Meet integrations, and Calendly branding. No payment collection or group events. If you only need one type of meeting and one calendar, the free tier works.
Best for: Freelancers or solo professionals who only book one type of meeting and want the most recognizable booking link.
9. TidyCal
TidyCal’s angle is a one-time lifetime payment instead of monthly fees. The free plan gives you 1:1 scheduling, one calendar connection, payment processing via Stripe and PayPal, and custom booking pages. Paid tiers unlock group bookings, video conferencing integrations, round-robin, and SMS reminders.
Best for: Budget-conscious users who want to pay once and never think about scheduling software costs again.
10. Setmore
Setmore’s free plan covers up to 4 users, 200 appointments per month, a branded booking page, and integrations with Salesforce, Zoho CRM, Zendesk, Slack, QuickBooks, and Mailchimp. Group classes and payment processing are included free. SMS reminders, recurring appointments, and two-way calendar sync require a paid plan.
Best for: Small businesses and service providers who need multi-staff appointment booking without paying for it.
11. Google Calendar Appointment Scheduling
If you already use Google Calendar, you have a free booking page built in. Google’s appointment scheduling feature creates a shareable link with your available time slots, and bookings automatically create calendar events for both parties. The free version limits you to one booking page; paid Workspace plans unlock unlimited pages, reminders, and payment collection.
Best for: Anyone already using Google Calendar who wants a basic booking link without adding another tool.
12. Rallly
Open-source meeting poll tool — propose dates/times, share a link, and participants vote on what works. No login required. Lightweight, privacy-focused, and self-hostable. The hosted version is free for most use cases.
Best for: Organizing group events where you want a simple date poll instead of an availability grid.
13. LettuceMeet
A modern, cleaner version of When2Meet. Drag-select your availability on a grid, share the link, and participants fill in their free times. Multi-timezone support works automatically and the mobile experience is far better than When2Meet’s. No account required; optionally sign in with Google to auto-fill busy times. Completely free.
Best for: Casual group scheduling where you want a simple availability grid that works on phones.
14. When2Meet
The original availability grid, running since 2008. Create an event, share the link, everyone paints the times they’re free, and a heatmap shows overlap. No accounts, no login, nothing to install. The UI barely works on phones and doesn’t integrate with calendars, but it loads instantly and millions of people know how to use it.
Best for: Quick, no-friction group availability checks when you don’t need any integrations or polish.
How to Pick the Right Free Tool
