A 1 MB file. 250+ features. Zero external dependency.
A concentrate of expertise: Gantt, Kanban, budget, resources, encrypted collaboration.
We had a SaaS tool at 22 EUR per seat. With 8 people, that was over 2,000 EUR per year — to manage schedules we exported as PDF anyway. With MasterGantt, I paid once, period. The file runs locally, nobody needs an account, and data stays with us. I should have done the math much sooner.
Our IT department systematically blocks cloud tools for anything related to R&D projects. MasterGantt is an HTML file we drop on our internal server. Zero external requests, zero data leaving. We validated the integration in half a day. It's exactly what we'd been looking for two years.
At first I wondered how it worked without a server. Turns out it's simple: I work, every change is saved automatically on my device. Once a week I do a .json export to my Drive — that's my external backup. When I switched laptops, I imported the file, up and running in thirty seconds. It's actually more reliable than any cloud.
We work with sensitive production schedules. The fact that .mgp files are locked to our license changes everything: even if a file leaves the company, nobody can open it. Our project managers export weekly, we archive on the internal network. Simple, traceable, our data has never left our walls.
