RationalPlan

Desktop and cloud Gantt software for multi-project planning and scheduling.

RationalPlan is project planning software built around Gantt-chart scheduling, resource leveling, cost tracking, and earned value analysis, following a PMBOK-style methodology. It's available as a desktop app for Windows, Mac, and Linux, as a browser-based cloud version, and as an on-premise server edition, and it can open and edit Microsoft Project files.

Plans range from a free cloud tier with limited projects and storage up to paid multi-project cloud subscriptions and one-time on-premise licenses. It suits project managers who want traditional, structured scheduling without committing to Microsoft Project or a fully collaborative cloud suite.
