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.

We’ve compiled a list of the three top-rated free and open-source wireframe software solutions from Capterra’s directory.
