Devdocs
DevDocs is an open-source API documentation browser that consolidates documentation from multiple programming languages, frameworks, and libraries into a single, fast, searchable interface. It provides offline access to documentation, enabling developers to browse API references without an internet connection. The project is maintained by freeCodeCamp and is available both as a hosted service at devdocs.io and as a self-hosted application. It includes features like instant fuzzy search, keyboard navigation, dark mode, and the ability to customize the documentation set by enabling or disabling specific docs. DevDocs uses a scraper architecture to fetch and parse documentation from original sources, then serves them in a unified format. It supports a wide range of technologies including JavaScript, Python, Ruby, Go, and many others.
