ContentTools vs Marvel

ContentTools is a JavaScript library for adding WYSIWYG editing to HTML pages. Developers include its CSS and JavaScript files, mark the page regions that should be editable, and configure the editor to initialize from those regions. Editing tools support inserting and converting images, videos, tables, and lists; users can drag blocks to rearrange them and resize images and videos. Undo and redo are supported without a stated limit during an editing session. Developers can define a palette of styles for eligible elements. The library is framework agnostic and extensible, and its five component libraries can be used independently. The maker describes integrations with CMS applications and web frameworks including WordPress, Yii, Laravel, and Django. ContentTools is free and MIT licensed. It does not store edited content or provide user authentication, so developers need to configure their own save mechanism. Its image-upload interface includes rotation and cropping, but the demo simulates those functions without a server-side API. Pre-built project files are available in the repository’s build folder.

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.
