ExDoc

ExDoc is the definitive documentation tool for the Elixir ecosystem, engineered to produce highly accessible, searchable, and mobile-friendly documentation from source code and Markdown files. Architecturally, it leverages the Earmark parser to transform Markdown into structured HTML and EPUB formats, while introspecting compiled Elixir bytecode to extract typespecs and function signatures. In the 2026 market landscape, ExDoc has evolved beyond a simple static generator into a critical node for 'AI-Ready Documentation.' By providing highly structured, semantic HTML and JSON outputs, it serves as the primary data source for RAG (Retrieval-Augmented Generation) pipelines that power developer-facing LLM agents. It integrates natively with Hex.pm, the Elixir package manager, ensuring that every library in the ecosystem maintains a consistent UX. Its performance is optimized for large-scale distributed systems, capable of indexing thousands of modules in seconds. The tool also supports interactive 'Livebook' buttons, allowing developers to jump from static documentation directly into an executable, collaborative notebook environment, bridging the gap between reference material and live experimentation.
