6 free alternatives to Quant-UX

UXPin's free tier gives you a small but concrete prototyping setup: up to 2 prototypes, 50 AI credits per month, built-in coded libraries with MUI components, password-protected preview, and 7 days of version history. That makes it useful for teams that want to test a higher-fidelity workflow or try code-aware prototyping without paying up front. The main free benefit over Quant-UX is the presence of built-in coded libraries and AI credits, which can help with design-system-style work. It falls short on volume, since Quant-UX allows unlimited prototypes and unlimited user tests. Switch if you want a structured, feature-specific free ceiling rather than open-ended testing.

• Beats Quant-UX: Built-in coded libraries and AI credits
• Falls short: Unlimited prototypes and unlimited user tests
• Who should switch: Switch here if you want a tighter free prototyping cap but need code-aware components and versioned preview workflows.

Proto.io's free offering is a limited account with 1 user, 1 active project, 5 prototype screens, 10 MB storage, preview in the Proto.io app, export to HTML, export to PNG and PDF, import from design tools, branding included, single-click sharing, and no additional reviewers. That is a practical free starter for teams that need to share a small number of mockups and export assets without paying. Its free plan beats Quant-UX on export options and on having explicit project, screen, and storage limits that make the free envelope easy to understand. It falls short badly on scale, because Quant-UX includes unlimited prototypes and unlimited user tests. Choose it if your free work is small and you care about exports.

• Beats Quant-UX: Export to HTML, PNG, and PDF
• Falls short: Unlimited prototypes and unlimited user tests
• Who should switch: Switch here if you only need one small active prototype and want export and sharing features in the free plan.

Lyssna's free plan includes unlimited quick studies, 3 seats, 15 self-recruited test and survey responses, core methods, GDPR compliance, live chat support, panel access, spaces, and user interviews. It is the best fit when the free need is broader research rather than just prototype testing, because it bundles surveys, interviews, and panel access in one place. Compared with Quant-UX, its advantage is the extra research workflow and included seats, which makes it more suitable for small teams running varied studies. It falls short on scale for self-recruited responses, since that response count is capped. Move here if your free work is research-heavy and you need more than prototype feedback alone.

• Beats Quant-UX: 3 seats and broader research methods
• Falls short: Unlimited user tests
• Who should switch: Switch here if you need a free research workspace with interviews and panel access, not just prototype testing.

Marvel's free plan is simple: the page says it has no time limits for ongoing use before upgrading. That makes it appealing for builders who want a perpetual starter workspace without a stated expiration date. The main free advantage over Quant-UX is the same kind of indefinite access, but with Marvel you are looking at a general design and prototyping workspace that can cover wireframing, prototyping, testing, and handoff in one place. What it lacks is any concrete quota or usage detail in the free tier, so you cannot plan around project counts, storage, or response limits. Pick Marvel if you want indefinite free use and can live with sparse quota detail.

• Beats Quant-UX: No time limits for ongoing use
• Falls short: Unlimited prototypes and unlimited user tests are explicitly stated
• Who should switch: Switch here if you want perpetual free access and do not need clear usage quotas on day one.

Figma's free tier gives you unlimited drafts for work in progress, UI kits and templates, 150 AI credits per day up to 500 per month, and free limited access to Figma products. That is useful when the free need is collaborative design work as much as testing, since drafts and shared workflows are the core of the product. It beats Quant-UX on the breadth of design workflow around drafts, templates, and AI credits, while Quant-UX is more directly centered on unlimited prototypes and unlimited user tests. It falls short because the free tier is described as limited access rather than an open-ended research/testing package. Choose Figma if your free work starts with design files and only later becomes prototype testing.

• Beats Quant-UX: Unlimited drafts and templates
• Falls short: Unlimited user tests
• Who should switch: Switch here if you need a free design workspace first and a testing tool second.

SurveyMonkey's Basic plan lets you view up to 25 responses per survey and send one survey on a free account, with responses beyond the Basic limit subject to deletion after 365 days. That makes it a basic option for one-off feedback collection rather than ongoing product testing. Its free advantage over Quant-UX is that it is clearly defined for survey collection, so you know the response ceiling and retention behavior up front. It falls short on prototype work, collaboration, and the broader testing workflow that Quant-UX includes for free. Move here if your free need is a simple survey cap, not interactive prototyping or usability testing.

• Beats Quant-UX: Clearly defined survey-response limits
• Falls short: Unlimited prototypes and unlimited user tests
• Who should switch: Switch here if your main need is collecting simple survey feedback with a small, explicit free cap.
