FluidCalendar
Open-source calendar and task app that aims to auto-schedule tasks into your free time.
Self-hosted task scheduling with Google and Outlook calendars; early-stage.
FluidCalendar is an open-source alternative to Motion that tries to place tasks on your calendar using your work hours and buffer settings. It suits tinkerers who want self-hosted auto-scheduling and accept bugs.
What it is
The README describes intelligent task scheduling and calendar management, syncing with Google Calendar and Outlook through OAuth, with Google Tasks sync mentioned. A CalDAV option appears in the open-source feature table.
Who it's for
It suits developers comfortable with Docker and OAuth setup. The README warns it is in active development, very buggy and not recommended for production.
