Tandio vs Trello

How do Tandio and Trello compare?

Criteria	Tandio	Trello
Primary organizing structure	Tasks grouped into named projects; each task can have subtasks, a due date, and an assignee.	Boards made of lists (columns) and cards (items). The board is the primary unit of work.
Task depth (subtasks)	Subtasks are a first-class feature, nested under parent tasks.	No native subtasks. Checklists inside cards serve a similar purpose but are not independently trackable tasks.
Views	List view and calendar view available across plans.	Board (kanban) is the core view. Timeline, calendar, table, and dashboard views are available on paid plans only.
Time tracking	Built in.	Not built in. Available through third-party Power-Ups.
Pricing model	Workspace-based: $10/month flat for the Pro plan, regardless of how many people are in the workspace.	Per-seat: paid plans are billed per user per month. Cost scales directly with team size.
Customization and integrations	Focused feature set; limited configuration options by design.	Highly extensible through Power-Ups (integrations and custom fields). More configuration overhead.

Your tasks naturally break into subtasks and you want those tracked independently, not as unchecked items in a card's checklist.
You need a calendar view on a free or low-cost plan—Trello limits non-board views to paid tiers.
Your team is larger than 3–4 people and per-seat costs add up quickly; Tandio's flat workspace price stays fixed regardless of headcount.
You want time tracking without configuring a Power-Up or connecting a third-party service.
Your team does not already have a kanban workflow established, and a project-and-task structure feels more natural than a board-and-card model.
