Overflow vs Slickplan

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.

Slickplan is a collaborative website-planning suite for content and UX teams, delivered through the web with API access. Its tools include Sitemap Builder, Diagram Maker, Content Planner, and Design Mockups. The Sitemap Builder’s AI assistant can generate site maps, refine structure, and improve page labels in multiple languages. It can crawl an existing website and import URL, XML, or TXT files. CMS plugins transfer structures, content, navigation, and SEO elements to WordPress, Joomla, and Drupal. Listed integrations include Basecamp, Slack, Teamwork PM, and Google Analytics. The REST-style developer API uses SSL JSON requests and OAuth 2.0. Teams can collaborate in real time, use version history, and export PDF, image, or Slickplan XML files. The free version allows one sitemap and one user, with basic functionality, limited support, and web-link-only sharing. Paid plans start at $10.79 a month billed annually, and a 14-day trial is listed.
