Tasks, a board, roadmaps, and time tracking, with almost every part optional. Start with a simple board and switch things on only when you actually need them.
Free while in beta.

Switch cards between Minimal, Compact, and Detailed in one click. Define your own statuses, drag cards across columns or move them from the keyboard, and filter by assignee or department.

Types, priorities, estimates, and assignees when you want them. Break a feature into subtasks, discuss it in comments with @mentions, and see a full history of what changed.

Lay Alpha, Beta, and 1.0 across the calendar. Zoom from auto to month, quarter, or year, watch progress fill per milestone, and a red Today line shows where you actually are.

Pick a milestone and see each task underneath: progress, estimated hours, tracked hours, and whether you're over or under. A burndown sits right above the table.
Start a live timer on a task or log time by hand. Filter by person, add a note to any entry, and the same numbers feed straight back into your milestone burndown.
Almost everything here is optional. Turn task types, estimates, priorities, departments, roadmaps, and time tracking on per project, and use roles to decide who can do what.
