These publish a tier that costs nothing, so they can be evaluated before any money changes hands.

What you would be giving up

Proto.io is most often brought in for running usability tests where the prototype must respond to real input rather than replay a fixed click path, demonstrating a form-heavy or data-driven flow to stakeholders before any code exists, testing a mobile interaction on the physical device it is designed for, with correct gesture behaviour, validating a concept for a client who needs to feel the product, not watch a video of it. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.

Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.

If Proto.io is broadly right and the question is cost, the Proto.io pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Design category lists everything the directory holds, and best design tools ranks them.

Proto.io runs on web, ios, android. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
