Instead of Open Planner Studio

Open Planner Studio alternatives

Open Planner Studio focuses on construction schedules for buildings, infrastructure and civil works. It combines Gantt charts, critical-path calculation and resource planning, with calendars for holidays, frost delays, inspections and project phases. Schedules use IFC 4.3, and the app also handles CSV, MS Project XML, Primavera P6 XML and native MPP files. It runs on Linux, macOS, Windows and the web, and is free with no subscription or per-seat licence fees.

Its Available Beta status may lead some teams to consider alternatives, especially if they need a different planning focus or broader project management. Compare how each option handles resources, collaboration, file exchange and access across devices. Open Planner Studio’s construction calendars and IFC workflow may be useful for building and infrastructure work, while another product may suit general project schedules, resource portfolios or simpler online Gantt editing. Also weigh any paid plan against Open Planner Studio’s free offering and consider whether browser access, desktop use or mobile availability matters to your team.
