What do you like best?
This software has many interesting features, first of all it is free, i really like that it can be used completely in the browser without the need to download it, it does not consume many resources of memory, video, processor, etc, run so smooth with high performance, also it has a great catalog of templates of different types of diagrams, such as uml, object, component, activity, use case, and it allows you to create your own diagrams, I also like the great variety of auto-forms that it includes, there are even 3D objects, however What I like most, is that I can save, my work directly in the cloud from the web page, and I can also download them from anywhere.
What do you dislike?
I did not like that it only allows to work with predefined forms and only whole objects can be erased, reason why the superposition of forms is something tedious, can not connect with visio.
Recommendations to others considering the product
I recommend it for students, professionals, or anyone, since you do not need to know or have advanced knowledge in drawing diagrams, can help organize and develop different models of a fast time, with a very clean appearance, it is free software so there is not reason to don't use it if you are looking for software to make diagrams.
What business problems are you solving with the product? What benefits have you realized?
With draw.io I can create diagrams in record time, with very good aspect, besides that it allows me to import the diagrams in several formats, like jpg, pdf, png, svg, etc. I can also create a direct link to the diagram and share it, and by being able to save them directly in the cloud I can access them from any device, at any time.
