ConstructionOnline vs Open Planner Studio

ConstructionOnline is a construction management platform with tools for estimating, scheduling, project management, communication, and finances. Estimating and financial features include client selections, change orders, proposals, costbooks, invoicing, and two-way QuickBooks Online integration. For planning and job tracking, teams can use Gantt schedules, project calendars, baseline tracking, daily logs, to-do lists, punch lists, and checklists. Daily logs can record jobsite work, weather, deliveries, delays, equipment, materials, visitors, and safety information. The iOS and Android app provides field access to project activity, photos, documents, logs, task lists, and schedules; it requires an internet connection, iOS 15.5 or later, or Android 8.0 or later. Listed integrations include Google Drive, Google Calendar, OneDrive, Outlook Calendar, Dropbox, Box, QuickBooks Online and Desktop, PlanSwift, and CAD imports. A private REST API with read and write access is available by request to Business and Enterprise subscribers. Pricing is on request, with a free trial but no free plan. The company history says UDA Technologies was founded in 1999; the company is based in Auburn, Alabama.

Open Planner Studio is an open-source construction planning tool for buildings, infrastructure and civil works. It provides Gantt charts, automatic critical-path calculation, resource histograms and automatic levelling when resources are overallocated. Schedules use native IFC 4.3; the app imports and exports IFC, CSV, MS Project XML and Primavera P6 XML, and opens MS Project MPP files. Construction calendars can account for holidays, recesses, frost delays, inspections and phasing, with task durations entered in days or hours. Reports export as PDFs at approximately 220 DPI, on paper sizes up to A2, with baseline overlays and status or progress lines. A built-in MCP server allows compatible AI clients to read and edit schedules, with pause, read-only mode, backups and an activity panel. Schedules are stored as IFC files rather than a proprietary closed format. Crash recovery is available, alongside optional periodic saving to a writable project file. The app is marked Available Beta and includes an offline manual in fourteen languages. It runs on Linux, macOS, Windows and the web.
