Operon

Operon is a task and project management plugin for Obsidian. It keeps work in plain Markdown notes, where tasks can live inline inside a note or in a file of their own, and the two forms can be converted into each other while preserving the task's identity. A single task editor handles structured fields for both kinds. Projects can be broken into parent tasks and subtasks with progress followed on the parent, and users can define their own pipelines, statuses and priorities. The same tasks appear across connected views: Calendar, Kanban, Table, Gantt with dependencies, Filters and Canvas. Daily features include a Task Finder, a pinned task dock, time tracking from the task, recurrence and reminders. It works on desktop and mobile. For AI use, the Operon CLI and ready made skills let an agent read, create and update tasks through a live Operon Runtime, so a person and a coding agent can work from the same task list. The CLI workflows require Obsidian Desktop to be running. It is aimed at Obsidian users who want task and project tracking inside their notes, including those who work alongside AI agents. The site describes it as open source and free to use, and publishes no paid plans.
