Features of Alloy

One-click capture of existing webpages or app interfaces via a browser extension, automatically importing their design systems, component libraries, and visual styles as the starting point for the prototype.

Supports generating new ideas, editing existing prototypes, or inserting AI-generated images via natural language prompts to accelerate design iteration.

Supports recording multi-step user flows to provide richer interactivity beyond single-page prototypes.

Integrates with 20+ tools, including Jira, Linear, Slack, Notion, and other product management and collaboration platforms.

Allows instantly sharing finished prototypes via a link with team members and stakeholders to collect feedback and collaborate on reviews.

Can export completed prototypes to leading design tools like Figma for handoff or deep editing.

Available as a browser-based online tool; you can run it as a desktop app on macOS and Windows using WebCatalog Desktop.

Use Cases of Alloy

PMs rapidly turn ideas into interactive, high-fidelity prototypes for internal demos and requirement clarification when receiving user feedback or new requests.

Designers can quickly generate brand-compliant prototypes to test new UI designs or interaction flows on top of the existing product.

Before usability testing, teams create prototypes that mirror the real product experience to collect more accurate user behavior and feedback data.

Founders or business leaders can create intuitive, professional interactive demos to present product concepts or new features to investors or customers.

Development teams can specify function details, interaction states, and component specifications through high-fidelity prototypes before coding begins, reducing miscommunication.

UX researchers planning complex multi-step user journeys can quickly build complete flow prototypes that include page transitions and form filling.
