| What it does | Collaborative documents the server cannot read, with no account to start | Several people typing in one document without overwriting each other | Paint your free hours on a grid and watch the group overlap darken | Open-source scheduling links you can run on your own server |
| What it costs you | No sign-upWorks the moment the page loads. No account, no email, no trial. | Free accountFree to use, but you have to register before it will do the job. | No sign-upWorks the moment the page loads.

| Where it stops | Pads created without an account are deleted after three months of inactivity. | Editing needs a Google account, and offline access only works if you set it up before losing the connection. | It only finds the time — nothing is written to anyone's calendar and there are no reminders. | Team scheduling, routing forms and white-labelling are paid — only the individual booking page is free. |
