Choosing well
Check platform support
Android access can matter when you review or share work from a Xiaomi, Redmi or POCO device. Check the product's platform details before signing up.
Tools on this list run on web, macOS, iOS, Windows, Android or Linux, with availability varying between products.
Compare free plans and trials
A free plan can help you start without a subscription. Check what the plan includes, then compare the stated paid starting price when your needs grow.
Some entries include trial periods. Justinmind's pricing note shows a 10-day trial, a free plan and paid plans from $19 per month.
Match the interaction features
Look at whether each tool supports interactive prototypes and conditional logic. These features can affect how closely a prototype follows a user's path.
User testing and prototype sharing are separate comparison points, so check both when feedback or handoffs are part of your workflow.
Plan for collaboration
If several people will work on a project, compare the team collaboration options shown for the tools. Also check how prototypes are shared with reviewers.
Billing units differ between products: Visily starts at $11 per user per month with annual billing, whereas Moqups starts at $7 per user per month on annual billing.
Use the listed starting prices carefully
Starting prices are useful for an initial comparison, but the billing unit matters. PrototypeTool's paid plans start at $29 per month, while some other tools quote annual prices per user.
Confirm the plan terms and free-plan limits on the product page before choosing a paid option.
