What OpenProject is
OpenProject is open-source project management with Gantt charts, agile boards and time tracking, self-hostable or cloud. Self-hosting puts roadmaps, requirements and time data inside your own network, which is often a hard requirement in public sector and regulated work. The cost is that you run the upgrades and the database.
What Smartsheet is
Smartsheet manages work in a spreadsheet-like grid with automations, dependencies and reporting layered on. The grid is deliberate: teams that already run projects in spreadsheets can move across without learning a new mental model, then gain Gantt views, approval workflows and cross-sheet reporting they could not build in a spreadsheet. It suits operational and portfolio work more than software development, where board-based tools fit the rhythm better.
