Plandera
What Plandera is
Plandera is an open-source calendar and to-do application for personal self-hosting. It runs as a web app or on your own infrastructure and encrypts data client-side before transmission through a zero-knowledge architecture. Calendars support creating, editing, and managing events, including recurring patterns. Tasks include priorities and due dates, with smart scheduling. Projects use a hierarchy that can be reordered by dragging items. WebSocket-based updates synchronize changes across devices in real time. Deployment on personal infrastructure uses Docker Compose. The responsive interface offers dark and light themes and can detect the system preference. Plandera lists Next.js, React, TypeScript, a Rust backend, PostgreSQL, and Docker among its technologies. The Personal Self-Hosted plan includes unlimited calendars and tasks, end-to-end encryption, Docker deployment, community support, and regular updates. Business subscriptions add enterprise features and priority support, with monthly or annual billing and a stated 20% annual-billing saving. The license is for personal self-hosting only.
