FluidCalendar

FluidCalendar is an open-source calendar and task management application focused on intelligent scheduling. It helps plan tasks into available time slots while integrating with external calendar providers for a consolidated view of your schedule.

Key Features

• Intelligent task scheduling to place tasks into available time blocks based on preferences
• Calendar management UI with time-blocking style views
• Integrations with Google Calendar and Microsoft Outlook (via OAuth)
• Optional CalDAV integration for additional calendar providers
• Configurable system settings and environment-based configuration
• Container-friendly deployment with a bundled PostgreSQL setup

Use Cases

• Personal time-blocking and automatic planning of daily tasks
• Combining multiple calendars (work and personal) into one scheduling workflow
• Teams or individuals who want a self-controlled alternative to proprietary smart scheduling tools

Limitations and Considerations

• The project is in active development and may be buggy or incomplete, so it may not be suitable for production use yet
• Some features may differ between the open-source edition and the hosted SaaS offering

FluidCalendar is a good fit for users who want an open, customizable scheduling workflow with modern calendar UI and external calendar synchronization. It is especially useful for experimentation and iterative improvement while the project matures.
