Wroolo

Breaking a big project into nested tasks, tracking dependencies, and keeping the discussion next to the work is what Wroolo is built around.

Wroolo is a project management system that combines a work breakdown structure (WBS) with a nested kanban board, so you get the order of a WBS and the flexibility of a product backlog under one roof.

Sub-tasks can be nested endlessly, which suits complex backlogs that outgrow a flat board.

Beyond tasks, Wroolo includes an AI knowledge base, an electronic notebook, and discussion channels, so notes and conversations live alongside the plan.

The catch is breadth: a tool that mixes this many pieces may take longer to set up than a plain kanban app.

If your backlog is deep and interlinked, that trade is probably fair.
