Seavus Project Viewer Review 2026: Pros, Cons, Features, Cost

Seavus Project Viewer supports .mpp files created in Microsoft Project 2007, 2010, 2013, 2016, 2019, 2021, and 2024, according to its FAQ. It also opens .ssv, .xml, .xls, .mdb, .mpd, and .mpt files. Check the vendor’s current compatibility information against the versions your teams actually use. Before rollout, test representative plans, especially files with custom views or templates, so reviewers can confirm the information they need appears as expected.

No, Seavus Project Viewer is designed to open and view Microsoft Project files without a full Microsoft Project license. That can suit stakeholders who need to inspect plans but don’t author them. Check your organization’s software licensing requirements separately; the vendor’s product description isn’t a substitute for your procurement or licensing review. During evaluation, confirm that the viewer opens the plans your team receives and displays the views, reports, and project details reviewers rely on.

Users can’t change the project plan in Seavus Project Viewer. They can’t add or delete tasks, assign resources, or change task progress directly in the plan. The separate Task Update feature lets team members report progress on assigned tasks while leaving the plan unchanged. The vendor says this requires the feature to be enabled and the Seavus Add-in for Microsoft Project installed on project managers’ PCs. Confirm that setup fits your update process before relying on it for status reporting.

Yes, the vendor offers Windows and Mac versions, but their listed views differ. Windows supports 27 standard Microsoft Project views and user-defined views saved in a project plan. The Mac version lists Gantt Chart, Task Sheet, Resource Sheet, and Team Planner. If your reviewers use both operating systems, compare the views each group needs before choosing a deployment approach. Also verify current system requirements with the vendor, since its published compatibility details may change.

Windows users can open user-defined views saved in a Microsoft Project plan. The viewer also includes graphical reports for areas such as dashboards, resources, and costs. The vendor says users can customize report charts, fields, sorting, labels, and table formatting. Because the Mac FAQ lists a more limited set of views, don’t assume every Windows view or report is available there. Test the specific views and reports your stakeholders use on the operating systems they have.

The vendor’s Windows FAQ lists support for .mpp files up to 500 MB, but actual performance depends on the computer. It also warns that a device can run out of memory before reaching that file size. Treat the published limit as a reference, not a guarantee for your environment. Test your largest and most complex plans on the computers reviewers will use. Check how long they take to open and whether users can navigate the views they need.

The vendor says project data stays in-house and isn’t stored by the viewer. That statement alone doesn’t establish that the product meets your organization’s security or compliance requirements. The published materials reviewed here don’t identify specific compliance certifications. Ask your security and procurement teams to assess the product against your policies, including data handling, access controls, and any requirements for sensitive project information. Get current documentation from the vendor before approving plans that contain confidential data.

Use the 15-day trial to test real project files and review workflows before wider deployment. Include plans from the Microsoft Project versions your teams use, plus large files and any plans with custom views. Check that reviewers can find the reports and project details they need on their operating systems. If your workflow depends on task updates, test the required add-in and enablement steps with project managers. Record any gaps before deciding whether the viewer fits your rollout.
