Merlin Project (originally called Merlin in versions 1.x and 2.x) is a commercial project management software application for macOS, developed by ProjectWizards GmbH in Germany. It focuses on project plan creation, tracking the status of activities, assignment of resources, and managing budgets. It includes creation and visualization of Gantt chart activity timelines, work breakdown structure (WBS), net maps (project networks), mind maps, and resource workload in bar diagrams, histograms or time boxes.


Merlin Project can be used for traditionally phased project management (Waterfall model) in software development, construction, event planning or similar. Merlin Project calculates costs based on estimated work, resource assignment and resource rates, estimates start and end dates, calculates resource overall utilization, critical path and performs earned value analysis on task or project level complying with standard project management methods. The application can be used by single users or in teams.

Interoperability with Merlin Server

Merlin Project's capabilities were extended with the introduction of Merlin Server. Merlin Server was implemented for teams working with Merlin Project. Merlin Server is the central database which allows simultaneous access of the same project information by more than one users using multiple devices (macOS, iOS or a web browser).

Once subscribed to a shared project, the users work with their local files in offline or online connection to the Merlin Server. The vendor patented the sync function included in Merlin. Changes from any user on any device with online connection to the Merlin Server are immediately integrated and distributed to all other users and devices currently accessing the same project documents.

Changes from users not having currently an online connection to Merlin Server are saved locally into the files and synced to the server next time the online connection exists. Conflicts between the changes are automatically resolved by the patented sync function.

Sync without Merlin Server

Local files or such on cloud services like iCloud Drive,, Dropbox can be also edited in multi-user-mode. Merlin Project can resolve conflicts automatically and forward changes as they get saved.

Work areas

Public or private work areas can be used when users plan to make a major change without it being automatically pushed to other users before it is actually cleared. Once switched to the Private Work Area all changes to the project document are kept local, other users do not see those local changes. Also all public changes from other users are saved into the source document but are not automatically integrated in the local copy of the user in Private Work Area. When a user switches back to the Public Work Area, it is possible to choose to publish or delete the local changes.

Import / Export

Merlin Project supports import of and export[1] to various project management file formats including .mpp, .mpx and .xml (MS Project), NovaMind, MindManager, and Freemind (mind mapping software). Merlin also integrates with macOS: It can publish project activities or resource assignments to Calendar or todos in Reminders, access the Contacts or Outlook for resource (staff) management,[2] and create email messages to project stakeholders from current view. It may also send other configured views. Merlin reports can be printed or exported as image (PDF, PNG, JPEG, TIFF, BMP or GIF).

Targets for files with exported content can be local paths, connected network drives, FTP, WebDAV or SMTP mail servers. Latter requires configured accounts with login data to the server accounts. Automated and unattended exports for reporting reasons can be configured for projects shared by Merlin Server.

iOS app In April 2009, Merlin was released for the iPhone. It integrated with Merlin 2 and/or Merlin 2 Server. With the release of Merlin Project Go Version 4.0.0 on June 2016, the iOS app supports the Merlin Project file format. It can be used as companion to Merlin Server or as a standalone app creating and editing project files on the iOS device.

Even though the iOS version maintains general feature parity with the desktop version, not included are reports, net maps, mind maps, and resource workload in bar diagrams, histograms or time boxes.

Version history and awards[edit]

It also supported import from Microsoft Project, NovaMind, OmniOutliner, and MindManager, and synchronized with iCal. Version 2.0.3 was reviewed and scored 4 mice by MacWorld (April 2007):[4]

"Merlin 2.0.3, from Project Wizards, is project management software that is not only as good as its Windows competition, Microsoft Project, but much better. Merlin 2 takes the excellent foundation provided by the initial version of the software ( ) and evolves it into the kind of intuitive program that leverages the best features the Mac has to offer."[5]

On December 2007 it received a MacWorld 2007 Editor's Choice Award.[6]

Merlin 2.5 was released in January 2008 and added project publishing functionality: Merlin users could now work simultaneously with others on the same project over the network.

The iOS app performs autosave, this action does not require online connection to the internet or Merlin Server.

When the device goes online again, the iOS app, iCloud Drive or the Dropbox account syncs the changes automatically.
