draw.io is an online diagramming tool with integrations with Jira, Google, and Confluence available free online or at cost depending on integration chosen.
Draw.io is a solid, no-additional-cost (included with G-Suite) substitute for OmniGraffle for our use case. The client can view and collaborate on documents produced with draw.io without us having to go through an export process, or the client having to own an additional piece …
Because we're primarily a Mac shop, Visio was a non-starter. (It's monstrously complex compared to OmniGraffle, which works against the quick-and-dirty just-enough-documentation ideal common on agile teams.) We've used draw.io on internal projects and when coordinating with …
It's very easy to collaborate on the same file with team members and create simple concepts and flowcharts that you can use in the development process. It is also very handy for creating graphs and tables for presentations. Since this is a web application, we can use it anywhere, anytime and on any device; which provides great flexibility and accessibility. It also offers the functionality to save your work as you develop it, which is very helpful.
Omnigraffle is great for documentation, mapping, flowcharting, and other technical diagramming scenarios. It's simple enough to bang out a quick illustration and powerful enough to build complex blueprints for complicated technical systems. If you need cross-platform compatibility, though, you're probably better off looking elsewhere. If you want complex integration with data sources (ala Visio's SQL Server integration for shape metadata), OmniGraffle also falls short — but those scenarios are few and far between in my experience.
Draw.io offers a lot of shapes and customizability of how the diagrams are laid out. We've been able to create a lot of different things with it, and have barely scratched the surface of the sorts of things that we could do.
Draw.io is fairly intuitive in the way that you draw shapes and connect shapes together, I was able to figure it out without a tutorial.
Draw.io is fast and performant for me compared with some of the alternatives.
OmniGraffle is fairly simple to use, but the one thing I think it does best is working with curved lines, particularly if you are using some of the available arc templates. Drop an arc onto your page, then tell it the dimensions it needs to be, and viola! Done. Manipulating the arcs is as simple as clicking and dragging offset points.
OmniGraffle has also done an excellent job in stirring up the creative minds of many people who create templates and tools to work with OmniGraffle (not that Microsoft hasn't done so either), and managed to get the bulk of those into well organized repositories.
What it all boils down to for me is: it just works. One doesn't need to have a computer science degree to work with it either. It is as simple or complex as you want it to be.
One element that was hard to use was converting pre-existing drawings and workflows from Gliffy to Draw.io once our company made the change. While we were able to complete the migration, when going back we noticed, oftentimes, some formatting and dependencies did not make it or were not compatible.
While the template repository is vast, it has a heavy focus on network style maps. It would be ideal for added diversity in the templates with a focus on workflows just as much.
While the integrations are strong, the cloud collaborative environment could still use some work. While you can save and edit in the cloud. Group editing and live dynamic sharing/editing similar to Microsoft office are still missing.
Draw.io could add some version control functionality for ease of rollback, auditing, & comparison.
There could be more scaffolding to support new users in getting to know how to best use all of the many features and tools it provides.
There could be more support for printing. Many of our process flows extend beyond just one page, and OmniGraffle is rather finicky about printing multipage documents.
We could use this tool more effectively if there was the ability to have real-time team collaboration. Document handoffs can be a point of missed communication, so it’d be great if we could ever have the option of working together in the same place at the same time.
The support for draw.io is pretty decent, considering it is a free website. I had a question one time when I was trying to do something, so I sent an email to their support email and got a response fairly quickly with an answer to my question. They also have some excellent support tools on their support website for helping you get more familiar with their program, and I found that very helpful.
Draw.io is totally free and it has most of the features a commercial product like Visio would have, so I think it is a go-to. It has good integration with Google Drive and it can export to a variety of files. You are not constrained by some commercial proprietary file format. It can be used in a browser on any device or downloaded as a desktop app.
use Omnigraffle for diagraming or for quick wireframe drafting
use Sketch for more in-depth wireframing that you can then flesh out into a high fidelity mock-up, export assets for production, and integrate with prototyping tools like Proto.io and UXPin.
