Our verdict on Marvel
Marvel is a browser-based UI design and prototyping platform for individuals, design teams, developers, researchers and stakeholders. It brings wireframing, interface design, interactive prototypes, user testing, collaboration and developer handoff into one workspace. Designs can be created in Marvel, imported from Sketch or based on uploaded images. Prototypes can be shared through URLs or embed codes, while implementation specifications, code and assets support communication with developers.
The freemium structure gives individuals a way to start with the Free plan, which includes 1 user and 1 project. Pro costs $12 per user per month when billed annually and adds unlimited projects, 3 active user tests, and downloads for prototypes or designs. Team costs $42 per month when billed annually, starts at 3 users, and includes unlimited projects, 10 active user tests and premium support. Enterprise includes unlimited users and projects, advanced security settings, Single Sign-On and custom billing. A 7-day free trial is also available.
Marvel’s strongest fit is a browser-first workflow that connects design, testing and handoff without requiring a desktop application. User testing supports screen, audio and video recordings, and collaboration includes comments, annotations, folders and permissions. Sketch synchronization and import help teams that already work with Sketch, while mobile access, integrations and API access support connected workflows. Teams seeking a focused tool for straightforward interface concepts, shareable prototypes and structured handoff should find the feature mix well aligned. Those needing deeper design-system or variable workflows should consider a more specialized alternative.
