CodeDocs AI vs Docny

CodeDocs AI generates searchable documentation sites from Git repositories. Its AI extracts function signatures, types, dependencies and relationships from a codebase. It supports TypeScript, Python, Go, Rust, Java, C#, Ruby, PHP, Swift, Kotlin and five or more additional languages, and is described as framework-aware. Connected repositories can update documentation on each push, while smart diff detection regenerates changed sections. Output sites include syntax highlighting, interactive examples and dark mode. The service is available through web and API platforms, though API access itself is listed as a Pro feature. The free plan costs nothing, is billed forever, and covers one repository and 10 pages per month with smart parsing and basic output. Starter costs $9 a month for three repositories and 50 pages per month, with custom themes, multi-language support and priority parsing. Pro costs $29 a month and includes unlimited repositories, 500 pages per month, API access, team collaboration and automatic push updates. The maker advises reviewing AI-generated documentation before use.

Docny is a hosted documentation CMS for developer teams, combining authoring, publishing, hosting and analytics. Content can be written in a WYSIWYG block editor or code-first MDX.

Managed hosting includes SSL, global CDN delivery, custom domains, versioning and one-click publishing. Teams get real-time cursors, inline comments and suggestion resolution, while published sites can include an AI assistant for reader questions.
