Worth knowing

Open Sunsama

  • The license is non-commercial: personal, educational and non-profit use is free, and for-profit companies need an enterprise license with no public price.
  • There is no native phone app yet; on a phone it runs as a mobile web app in the browser.
  • The desktop apps connect only to opensunsama.com, so a self-hosted install is used through the web app.
  • Team workspaces, auto-scheduling and integrations with Linear, GitHub, Jira and Notion are unchecked roadmap items, not shipped features.

Sunsama

  • There is no free plan. Workspace access stops when the 14-day trial ends unless you subscribe.
  • The $17 rate requires paying $204 per user for the year; monthly billing is $22 per user.
  • SSO, SAML, SCIM and audit logs are limited to the Enterprise plan, which has no public price.
  • Workspace data is permanently deleted 30 days after a cancelled subscription ends.

Key features

Open Sunsama

Kanban board of days
Tasks sit on a board with a column per day and a backlog. Each task can carry a P0 to P3 priority, a time estimate, subtasks, rich-text notes and attachments.
Drag-and-drop time blocking
Dragging a task onto the calendar creates a block linked to that task, and resizing the block sets its length. The calendar has day, 3-day, week and month views.
Calendar sync
Events from Google Calendar, Outlook and iCloud appear next to tasks and time blocks, so a day is planned around existing meetings.
Focus mode and rollover
Focus mode shows one task with a timer and records actual time against the estimate. Unfinished tasks roll over to the next day, and recurring tasks repeat on their own.
MCP server for AI agents
A hosted MCP server with 24 tools lets Claude, ChatGPT, Cursor and other MCP clients read the schedule and create or move tasks and time blocks after an OAuth sign-in.
REST API and self-hosting
A REST API with scoped API keys covers tasks, time blocks and ideas. The app can be run on your own server with Docker Compose, which starts PostgreSQL, Redis, the API and the web app.

Sunsama

Guided daily planning
A step-by-step routine: review yesterday, add today's tasks, check the predicted workload and set the order. Sunsama can prompt you to start at a set time.
Timeboxing
Drag a task to a time slot, or press X to auto-schedule it. The block shows up in Google, Outlook or iCloud calendar, or on Sunsama's internal calendar.
Tasks from other tools
Bring in work from Asana, Trello, Jira, Linear, Notion, Todoist, Gmail, Slack and others, and plan it alongside tasks created in Sunsama.
Focus mode and Pomodoro
Work on one task at a time with a timer, Pomodoro intervals, break reminders and the option to mute other apps.
Weekly planning and review
A weekly prompt to review where time went and what got done, then set objectives for the week ahead.
AI estimates and channels
Suggests a time estimate and a channel for each new task, based on work you have previously added to Sunsama.
