From getting approval from stakeholders to onboarding clients and continually incorporating their feedback—building websites and mobile apps is a complex, ongoing process with a lot of moving parts. If the project doesn’t get off to a good start, you’ll spend a lot of time and resources on bug fixes and updates.

A wireframe tool can help save the effort and cost of redoing work. You can draw up a basic design wireframe, create prototypes, share them with stakeholders and clients, and gather feedback in one place.

What’s more: There are free wireframe tools available that offer competent features.

Methodology

Products considered for this article must be free. We classified a product as free if:

  • It offers a free, stand-alone version of the software.
  • It is not a trial version of the software where you must purchase a product version after a limited amount of time.

Selection criteria

The products that met the above criteria were then evaluated against our wireframe software definition: Wireframe software aids users in laying out the bare bones of a design concept with the help of specific content, functions, and connections between static pages. Users can create wireframe designs with the help of a drag-and-drop editor, present it to colleagues and collaborate on wireframe designs.

This check verified the basic wireframe software capabilities and appropriateness for the category. A product was classified as wireframe software if it contained these core features—collaboration tools, drag-and-drop editor, design templates, presentation tools, prototype creation, wireframe creation, page linking, and dashboard.

Software that met this market definition also needed a minimum of 10 reviews published on the wireframe software category page between Sept. 3, 2018, and Sept. 3., 2019. During this period, the product’s rating also had to be higher than 4.0 out of 5.
