1. Customization: Docsify is highly customizable, allowing users to have full control over the appearance and behavior of their documentation websites. On the other hand, zeroheight offers a more structured and uniform design, limiting customization options to maintain consistency across teams and projects.

2. Offline Access: Docsify allows users to view documentation offline by caching the website, enabling access without an internet connection. In contrast, zeroheight requires an internet connection to access documentation, making it challenging to review content in offline scenarios or low-connectivity environments.

3. Collaboration Features: Docsify lacks robust collaboration features that facilitate team collaboration and knowledge sharing. Zeroheight, on the other hand, provides collaboration tools such as commenting, version history, and user permissions to enhance teamwork and information exchange within organizations.

4. Export Options: Docsify offers limited export options for documentation, primarily focusing on HTML and PDF formats. In comparison, zeroheight provides versatile export formats such as Markdown, CSV, or JSON, allowing users to efficiently migrate and integrate documentation with various tools and platforms.

5. Integration Capabilities: Docsify provides minimal integration capabilities with other tools and platforms, limiting its interoperability and data exchange. Zeroheight, on the contrary, offers seamless integration with popular tools like Slack, Jira, and Confluence, enabling users to enhance their documentation workflow and streamline processes.

6. Security Features: Docsify lacks advanced security features to protect sensitive documentation and data. Zeroheight, on the other hand, prioritizes security by offering features like role-based access control, encryption, and audit logs to ensure confidential information is safeguarded within the platform.

In Summary, Docsify and zeroheight differ in customization options, offline access, collaboration features, export options, integration capabilities, and security features, catering to distinct user needs and preferences.
