// EDITOR'S TAKE
Nothing here copies the spreadsheet-as-database idea outright, so the choice splits by what you actually use Smartsheet for: OpenProject if it is Gantt charts, work breakdowns and budgets, or Budibase if it is building small internal apps on tabular data. Plane and Taiga are polished but firmly agile issue trackers, so grid-first workflows and formula columns will feel absent.
