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
Checks live Google or Microsoft Free/Busy first, then lets anyone without a connectable calendar (Apple iCloud, Proton, none at all) paint free time at /free. Everything merges into one group heat-map, and 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 booking automation and 1:1 workflows
The category leader for booking links, event types, routing, reminders, payments and sales/recruiting workflows. It also offers meeting polls, but the product is strongest when one host or team publishes bookable time and automates the follow-up.
Best-known group poll
The familiar way to ask a group which times work, with broader team-calendar products layered around it. Great when a poll is the desired interaction; less direct when you want live cross-provider availability before asking people to vote.
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
Outlook-native scheduling poll flow for Microsoft 365 users. Strong when the organizer lives in Outlook; less natural for a mixed Google/Microsoft/Apple group that should start from one web heat-map.
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.
| Tool | Free | Reads real calendars | Cross-provider | Manual fallback | Books event + call link | Guest sign-up |
|---|---|---|---|---|---|---|
| WhenMeet.me | Yes | Google + Microsoft | Yes | Yes (/free grid) | Meet / Teams | None |
| Calendly | Limited tier | Host/team calendars | Via connected workflow | Meeting poll | Yes | Host signs up |
| Doodle | Limited tier | Connected workflows | Via poll/workflow | Group poll | Add-on | None to vote |
| when2meet | Yes | No (manual) | n/a | Yes (grid) | No | None |
| Google Calendar “Find a time” | With Google | Google only | Google only | No | Meet | Google account |
| Microsoft Scheduling Poll / FindTime | With M365 | Microsoft first | Limited | Poll | Teams | MS account |
| Cal.com | Open-source tier | Own calendar | Within account | No | Yes | Host signs up |
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 or automating sales/recruiting workflows? 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 Scheduling Poll 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 stronger for booking pages and workflow automation; Doodle and when2meet are stronger when you intentionally want a poll-style interaction.
WhenMeet.me reads Google and Microsoft Free/Busy live, so the group heat-map appears without making every participant vote first. Google “Find a time” and Microsoft scheduling polls work best inside their own provider ecosystems. Doodle and when2meet are best understood as poll-first tools.
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.
