RationalPlan Review 2026: Pros, Cons, Features and Pricing

RationalPlan offers both a free, read-only desktop viewer and paid project planning editions. The viewer is for inspecting supported project files; it won’t let you change tasks or dependencies. If your team needs to create or update schedules, assess the paid desktop, cloud, or Server edition against your planning workflow. Don’t assume the viewer’s capabilities apply to every edition, or that a planning edition will match your specific requirements without testing it.

No. The free Project Viewer is read-only, so you can’t change task dates, dependencies, or imported project details. That makes it suitable for review, but not for correcting a schedule before it goes back to its author. If your team needs to edit Microsoft Project files, evaluate RationalPlan’s paid planning editions separately and confirm they support the editing workflow you need before choosing a license.

Test files that reflect your actual schedules, including the views and layout reviewers depend on. RationalPlan’s viewer supports .mpp and .mpt files, as well as .xml and .mpx, and preserves saved tables and Gantt splits. Check whether representative schedules open as expected and whether print or export output works for your review process. Some users report print-layout problems, so verify printed pages before making them part of an approval or audit workflow.

The free Project Viewer doesn’t support collaborative editing because it’s read-only. RationalPlan’s Server edition offers centralized, concurrent access and controlled permissions, which may be relevant if multiple people need access. The available information here doesn’t establish that every cloud plan supports the same collaboration features, so confirm how users share, update, and control access to schedules in the specific edition you’re considering. Test with your team’s actual review and approval process.

The available product information doesn’t establish specific security certifications, encryption details, data residency options, or compliance attestations. Don’t treat those requirements as confirmed. Before storing sensitive or regulated project data, ask RationalPlan for current documentation on encryption, access controls, retention, backups, and applicable certifications. Also check whether the answers apply to your chosen deployment—desktop, cloud, or Server. If your organization requires formal evidence for vendor approval, obtain it before loading production schedules.

RationalPlan integrates with Dropbox, Google Drive, and OneDrive for cloud file storage and supports Microsoft Project file compatibility. Google Calendar is listed by third-party directories, but native support remains unconfirmed. RationalPlan doesn't publicly document an API or integrations with automation tools such as Zapier and Make. Before choosing RationalPlan, confirm that its available connections support your required data exchange and project management workflows.

Start by opening a representative schedule in the free Project Viewer and checking the saved views, Gantt layout, and print or export output your reviewers rely on. If you want to evaluate planning features, RationalPlan’s unlimited trial is capped at 20 tasks, so it may not represent a large project. Use a small but realistic sample, and confirm which edition and trial terms apply before assessing workflows beyond file review.

RationalPlan offers tutorials and phone, email, and live chat support to help users with setup and troubleshooting. Paid editions include one year of priority support, which isn't available with the free viewer. Teams planning a rollout should confirm the support terms for their selected edition, particularly after the included priority-support period ends.
