1. Miro 

Miro goes beyond basic flow charts. It's a sprawling digital canvas for brainstorming, teamwork, and project tracking. Imagine a whiteboard with endless space to add sticky notes, mind maps, complex diagrams, and even live video chat with your team. Miro is ideal for remote teams or anyone who thrives on visual organization. Boost productivity with a toolbox that includes flow charts and other visual collaboration tools.

What users like best:

“First, I like the scalability of MIRO Whiteboards. You can quickly start with a small drawing and add more and more information, pictures, notes, and references to it. You can also end up with a large-scale drawing that still works and provides a decent overview of what you did. As a proper cloud-based solution, these results are available everywhere: on your PC, in the home office, virtual, and even in real-life meetings. So, results are not lost but can be reused and enhanced in collaboration. That’s the way I love to use whiteboards.” 

- Miro Review, Detlev P.

What users dislike:

“Though it's a must-have for marketing and salespeople, designers, developers, and project managers may sometimes find too many things overwhelm it. Also, integration with Zoho apps is missing. And when I add comments, I need to manually link each comment to the elements, which is very frustrating. I wish there could be an easier way to do this.”

- Miro Review, Manish S.

- Lucid Visual Collaboration Suite Review, Lisa M.

What users dislike:

“There are a lot of creation options, so make sure you watch their demos and step-by-step instructions so you don't get lost. Copy/cut/paste are not the same shortcuts in Lucid as in another platform.”

- Lucid Visual Collaboration Suite Review, Erin H.

3. Creately

- Creately Review, Surya Prakash M.

What users dislike:

“The least helpful aspect of Creately might be its limited functionality in the free plan, which may restrict users from fully experiencing the platform's capabilities without upgrading to a paid subscription. Next is its dependency on an internet connection. Since Creately is a cloud-based tool, it requires a stable internet connection to access and work on diagrams. This dependency on internet connectivity may pose challenges for users in areas with poor internet infrastructure.”

What users like best:

“The 3D view and integration with AWS (including the synchronization feature) make it incredibly easy to visualize and maintain your cloud infrastructure in real-time. As a cloud architect, I've tried many tools, but none of them have had the impact that CloudCraft diagrams produce on clients. They remain amazed at how much they can see about their existing or proposed infrastructure. It's also a fantastic tool for teaching about AWS cloud infrastructure and services.”

- Cloudcraft Review, Walter J.

What users dislike:

“It's a bit difficult to use the user interface on a laptop due to the trackpad. I always prefer using a physical mouse. Also, if they could provide suggestions based on the resources I use in my architecture diagram, that would be a great feature.”

- Cloudcraft Review, Aman M.
