OpenProj as a Linux alternative to Microsoft Project
Updated
Our verdict
OpenProj can serve as a basic replacement for Microsoft Project for small teams or solo users who need Gantt charts, resource leveling, and baseline tracking. It lacks advanced budgeting, integration with enterprise systems, and a modern UI, so larger organizations or those needing detailed cost analysis will find it insufficient. If you only need to create and edit standard Gantt charts and manage simple resources, OpenProj is a viable free option.

Opening your Microsoft Project files
OpenProj can read and write MPP files, allowing you to open projects created in Microsoft Project and save them back in MPP format. Compatibility is generally good for simple projects, but complex features like custom fields, advanced cost tables, or newer MPP versions may not be fully preserved.
Switching from Microsoft Project to OpenProj, step by step
- Export your current Microsoft Project file as MPP (or XML)
- Open the exported file in OpenProj to verify all tasks and resources appear correctly
- Adjust any missing fields or custom columns that OpenProj does not support
- Save the project again in MPP format if you need to share it back with Microsoft Project users
Key features of OpenProj
- MS Project (MPP) file import/export
- Gantt chart with drag‑and‑drop tasks
- Resource allocation and leveling
- Critical path calculation
- Baseline tracking
- Work breakdown structure support
- Customizable columns and views
Frequently asked questions
Does OpenProj support the latest MPP file format?
OpenProj supports MPP files up to the version it was last updated for, typically around Project 2003/2007. Newer features in later Project versions may not import correctly.
Can I use OpenProj for large projects with many resources?
OpenProj can handle moderate‑sized projects, but performance degrades with very large task lists or extensive resource assignments. For enterprise‑scale projects, a commercial tool is recommended.
Is there a way to collaborate on projects in OpenProj?
OpenProj does not have built‑in collaboration or cloud features. You would need to share files manually or use a separate version‑control system.
