Birdog vs Open Planner Studio

Birdog is construction scheduling and communication software for builders coordinating subcontractors. Its Gantt schedule calculates dependencies, float, and the critical path, with resource planning and schedule templates. Publishing a schedule queues reminders for subcontractor tasks, with follow-ups continuing while work is underway. Subcontractors can reply by text without installing an app or creating a login. Birdog says its AI reads replies in English and Spanish, including questions and reported delays. A delay can prompt a proposed schedule change for contractor approval or rejection; the downstream schedule recalculates after approval. A 6 AM digest summarizes confirmations, active work, schedule changes, and upcoming tasks. Birdog runs on Android, iOS, and the web. The Project license costs $150 a month per project license, with the whole team included at no extra cost. New customers may be offered a 30-day trial for one project; it requires a payment method and renews as a paid monthly subscription unless canceled before the trial ends.

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.
