Quant-UX vs Loveable

Loveable is an AI-driven no-code platform aimed at rapidly turning ideas into working prototypes or MVPs. It's built for speed, for founders, product managers, non-technical users, or teams wanting to validate ideas early without investing heavy engineering resources. While Loveable can quickly generate basic prototypes, it lacks the depth of features and user research capabilities found in Quant-UX.

Prototyping

Loveable's strength is in generating working frontend + backend scaffolding, so prototypes are not merely visual mockups but have actual functionality early. This gives teams something more tangible to test ideas with.
Quant-UX is similar, as it uses fully functional widgets that replicate real-world interface behaviors. This allows designers to build prototypes that behave similarly to production applications.
The key difference is that Loveable is chatdriven and AI-based, so the fidelity and customization of prototypes is limited to what the AI can generate. Quant-UX, on the other hand, provides a more traditional design interface, allowing for precise control over the prototype's look and behavior. This makes Quant-UX better suited for detailed UX design and testing.

User Testing and Research

Loveable has some feedback mechanisms and supports getting input, its focus is more on building fast. It tends to integrate certain backend or deployment features and allows sharing, but its analytics / research capabilities are marketing focussed and limited.
Quant-UX has stronger built-in capabilities: heatmaps, user journey visualization, task drop-offs, screen recording, metrics, A/B testing, linking usability tasks. These are all integrated, allowing more direct measurement of usability

Pricing

Loveable is a commercial product with a token-based pricing model. The longer you work on a project, the more tokens you consume. This makes it potentially expensive for extended use and iterating fastly over different ideas.
Quant-UX, on the other hand, is open source and free to use. You can use it for free, whether you are an individual or part of a large team.

Summary

Loveable is a great low code / vibecoding tool that also allows non designers to rapidly build fully functional prototypes. In contrast, Quant-UX is a powerful and flexible prototyping and user research tool that is designed specifically for user-centered design. Important! For serious user research, Quant-UX is the better option, but if you aim to launch a product fast and plish the user experience later, Loveable might be the better choice.
