Open Sunsama

AI-native, self-hostable open-source task manager and Sunsama alternative

PlatformWebfreeglobal

Open Sunsama is the first AI-native, open-source task manager, exposing an MCP server so AI assistants like Claude and Cursor can directly manage a user's calendar and tasks, alongside time blocking and a kanban board. It's a self-hostable alternative to Sunsama for people who want their daily AI assistant to actually manage their schedule.
