Hi Product Hunt! I plan projects in Google Calendar and Google Tasks, but a calendar shows days, not how tasks follow each other. The Gantt tools I tried all wanted me to move my work into them first. So I built CalGantt: it reads the calendars and task lists you pick and shows them as a Gantt chart. Drag a bar and the event moves in Google Calendar; tick a task and it is done in Google Tasks. A few things I cared about: - No server and no database: your browser (or Google Sheets) talks to Google directly. - Nothing changes on its own, your guests never get emails, and ↶ undoes your changes. - Dependencies, milestones, subtasks, Kanban, a Today view and workload per person. It works in two places: in your browser at app.calgantt.com (new, in beta) or as a Google Sheets add-on. Launch offer: every Pro feature is free for everyone until 30 November 2026, and the demo works without an account. I would love your feedback: what would make it fit the way you plan?
