In their own words
ContentTools
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.
Overflow
Overflow lets users create, present, share, and get feedback on interactive user flow diagrams. It syncs designs from Figma, Sketch, Adobe XD, and Adobe Photoshop. Diagrams can include customizable connectors, styles, device skins, hotspots, shapes, text, and multiple boards. Users can present playable flows, self-guided Stories, and rapid prototypes. Cloud publications can be shared by link, embedded, protected with a passphrase, exported as PDF or PNG, or printed. Collaboration includes personal and team folders, editor invitations, comments, mentions, and notifications, with integrations for Confluence, Jira, and Trello. Overflow is available on macOS, Windows, and the web. Its 14-day trial requires no credit card and gives desktop-app and Cloud-sharing access without limitations. After the trial, that access ends; data remains hosted for 60 days and is then deleted if no subscription is activated. Pro costs €19.95 per user/month, billed monthly, and includes 1GB cloud storage per user, Cloud sharing, folders, and comments.
