Marvel vs Proto.io

Marvel is a design platform for creating wireframes, mockups, prototypes, and design specifications. From a browser, users can make website and app designs for different devices, then share interactive prototypes that demonstrate intended interactions without coding. Its Handoff tool generates downloadable assets and CSS, Swift, and Android XML code that stays synchronized with design changes.

Teams can organize projects in folders, create teams, and leave feedback through comments and annotations. Marvel lists integrations such as Sketch, Jira, Confluence, Dropbox Paper, and Microsoft Teams, as well as a GraphQL API for project data and design activity. Its mobile apps let users create, play, and share prototypes, with offline viewing and Sketch syncing. The free plan allows one user and one project; moving down to the free plan makes other projects inactive. Pro costs $12 a month, billed yearly, and a seven-day trial is listed. Marvel was founded in 2013 and is headquartered in London.

Proto.io is a web-based, no-code tool for building interactive prototypes for iOS, Android, and web. It includes native iOS and Android apps, more than 250 UI components that mimic native behavior, and over 1,000 customizable templates.

Users can share links and snapshots or export to PDF, PNG, and HTML. The free plan is limited to one user, one active project, five prototype screens, and 10 MB of storage; it allows single-click sharing but no additional reviewers. A 15-day trial is listed. Freelancer costs $29 a month, billed monthly; annual billing is listed at $24 per month. Other listed monthly plans are Startup at $49.00 USD, Agency at $99.00 USD, and Corporate at $199.00 USD.
