Instead of Open Sunsama
Open Sunsama alternatives
Open Sunsama is a free, open-source task manager and daily planner built around time blocking. You move backlog tasks onto a daily board, roll unfinished work to tomorrow, and use a focus timer to compare actual time with estimates. It syncs multiple Google Calendar, Outlook, and iCloud accounts while keeping its time blocks private from those calendars. Desktop apps cover Mac, Windows, and Linux, and the service also offers web, API, Android, iOS, and self-hosted options, plus MCP access for AI clients.

Readers may still want an alternative because Open Sunsama has no automatic scheduling, no native phone app, and no one-click export. Self-hosting requires Docker, Compose, and 2 GB of RAM, while the non-commercial license requires a commercial license for company production use. When switching, weigh whether you need automatic rescheduling, stronger goal or priority systems, team collaboration, scheduling links, or a lower-cost commercial plan. Also check which platforms, calendar connections, and free-plan limits fit your routine.
