Microsoft Project
Microsoft Project is the long-standing enterprise standard for project scheduling, Gantt charts, and resource management. It's powerful for complex plans, but its licensing is costly (Project Plan 1 starts at $10/user/month, Plan 3 at $30/user/month) and it's largely desktop-bound with limited real-time collaboration. Many teams are moving to free or freemium alternatives that run in the browser, support real-time collaboration, and don't require a per-seat subscription.
PRICING
Project Plan 1 $10/user/month; Plan 3 $30/user/month; Plan 5 $55/user/month (billed annually)
ProjectLibre
ProjectLibre is the most direct free replacement for Microsoft Project. It opens native .mpp project files, supports Gantt charts, network diagrams, resource histograms, and earned value management. The desktop app is free and open-source, making it the go-to for users who just want Project without the license fee.

How to Migrate from Microsoft Project to ProjectLibre
- 1
Export your Microsoft Project plan as XML (File → Save As → XML)
- 2
Import the XML into GanttProject or OpenProject to preserve tasks and dependencies
- 3
For a direct desktop replacement, install ProjectLibre and open the original .mpp file
- 4
If you prefer a collaborative tool, create a ClickUp or Trello workspace and recreate the task board
- 5
Invite your team and confirm the new plan renders before cancelling the Project license
Pro Tips
- ProjectLibre opens .mpp natively — use it first if you just need to view/edit existing plans
- OpenProject is best if you need self-hosted, real-time, multi-user planning
- ClickUp/Trello trade deep scheduling for collaboration — pick them only if your team doesn't need true Gantt
