Let's also do a short overview of other software alternatives:
Active Collab is an online product that is visually pleasing and clear, but with a not very intuitive interface. The main features: you can create several projects, invite participants and clients to the project, link tasks. There is no possibility to export the diagram.
Excel is an old school of gantt charting, all by hand. There is no possibility to link tasks, manual creation of time intervals and histograms based on them.
GanttProject - is a specialized program for drawing gantt charts, but with an outdated interface. Features: each project is created as a separate file, as in MS Project; it can be exported to a picture and pdf file; it is impossible for several employees to work simultaneously, because it is not an online product.
Planiro is an online product, also visually pleasing, but the interface is also not very intuitive. You can create several projects, you can work with several employees online, you cannot export the diagram to a file.
Canva is a specialized product for creating beautiful graphic materials, including giant diagrams, for presentations. The peculiarity of the product - design, availability of a large number of templates, but not functionality, everything by hand. It is suitable for presentation of projects, but not for dynamic work with the diagram.
Wrike - online product with a decent design, clear and user-friendly interface. You can run several projects, work simultaneously for several employees. The disadvantage of the product is that you can export only in Excel.
OpenProj is a kind of MS Project analogue, but with an outdated interface. Quite wide functionality, but the disadvantage of the product is that you can not work with several employees at once, each project is a separate file. The possibility of exporting is available in pdf.
