If you spend more time arranging a meeting than having it, the right scheduler pays for itself in minutes a week. Here’s an honest look at the best free options in 2026 — and which job each one is actually best at.
Best for cross-company group scheduling, free
Reads everyone’s real Google or Microsoft Free/Busy and shows the whole group’s overlap as one heat-map — no poll to fill in. Anyone without a connectable calendar (Apple iCloud, Proton, none at all) paints their free time at /free and it merges into the same view. Confirming books the event with a Google Meet or Teams link. Free, no sign-up for guests. It does scheduling only — no hosted video, no AI notes.
Best for 1:1 booking pages
The category leader for personal booking links — share your availability and let others grab a slot. Great for sales and recruiting; the free tier is limited to one event type, and it reads only your own calendar, not the whole group’s.
Best known group poll
The classic when-are-you-free poll. Simple and familiar, but everyone fills in their availability by hand — it doesn’t read real calendars unless you pay, and you wait for replies before you can pick a time.
Best zero-friction availability grid
Free, no account, paint-your-availability grid. Loved for its simplicity, but purely manual (no calendar sync), one fixed time zone, and no calendar event or conference link at the end.
Best inside an all-Google team
Built into Google Calendar; overlays attendees’ availability instantly — as long as everyone is on the same Google Workspace. It can’t see Microsoft or Apple calendars across organisations.
Best inside an all-Microsoft tenant
An Outlook add-in that proposes times and runs a quick vote. Strong inside Microsoft 365, but limited to the tenant — external Google or Apple participants don’t get real Free/Busy.
Best open-source booking platform
Open-source Calendly alternative — self-hostable, developer-friendly, with a generous free tier. Like Calendly it’s built around individual booking pages rather than finding one time across a whole group.

Scheduling one time across several companies or calendar systems? WhenMeet.me is built for exactly that, and it’s free. Sharing a personal booking link for 1:1s? Calendly or Cal.com. Just need a dead-simple availability poll? when2meet or Doodle. Everyone already on one provider? Google “Find a time” or Microsoft FindTime work well inside their own walls.
For cross-organisation scheduling, WhenMeet.me is purpose-built: it reads real Google and Microsoft Free/Busy across companies and gives everyone else a manual availability grid, all free. Calendly and Cal.com are better for personal 1:1 booking pages; Doodle and when2meet are manual polls.
WhenMeet.me reads Google and Microsoft Free/Busy live, so the group heat-map appears without anyone filling in a poll. Google “Find a time” and Microsoft FindTime also read real calendars, but only within a single provider. Doodle and when2meet are manual.
WhenMeet.me writes the event to the host’s calendar with a Google Meet or Microsoft Teams link and emails ICS invites. Calendly and Cal.com also create events on booking. when2meet and a basic Doodle poll do not.
