Figma

Figma distinguishes itself as a sophisticated cloud-based alternative to products like Sketch and XD. And the greatest thing is that it doesn't discriminate against free users, providing a set of capabilities that function well whether you're a solo designer or part of a larger team.

The actual wireframing process using Figma is simple and quick. You'll need to develop your own UI components (or use one from a different, pre-designed kit), but it's simple to create artboards, add shapes and text, and even do some prototyping to get a better sense of the flow. The left-hand panel helps you arrange everything, from layers to artboards to various pages inside the same design document. If you like the Bootstrap grid system, you may use a column overlay for responsive design, or you can utilize Figma constraints, which specify each element how it should adapt when the design is resized to simulate different screen sizes.

Another feature that distinguishes Figma is its team collaboration capabilities. Because it's a web-based software, different team members may log in and view the design file at the same time, whether to change it or contribute content. The ability for a team to carry on a whole dialogue inside the design file, making sticky note-like remarks that other colleagues may subsequently react to or designate as complete, is the most appealing feature.
