DeepWiki-Open is an open-source wiki generator for code repositories. You enter a repository name from GitHub, GitLab or Bitbucket and it analyzes the code structure, writes documentation, creates diagrams that explain how the parts connect, and organizes everything into a wiki you can browse. It can also generate a codemap for code-centric guided tours. The project is released under the MIT License, so there is nothing to pay for the software itself, and the repository includes Docker files for running it yourself, including variants for LiteLLM and local Ollama models.
This project is for developers who inherit or join an unfamiliar codebase and want orientation fast. Maintainers of open-source projects can use it to give contributors a readable overview, engineering leads can use it to speed up onboarding, and self-hosting enthusiasts can run it against private repositories with their own model setup. Setup is more hands-on than a hosted product, so some comfort with Docker, environment variables and model providers helps.
Typical scenarios include generating documentation for a project that has none, producing architecture diagrams for a design review, and preparing a guided tour of a repository for new hires. Because it supports multiple git hosts and several model backends, such as Ollama and OpenRouter, teams can match it to their own infrastructure and privacy requirements. The repository has more than 18,000 stars on GitHub and README translations in a number of languages, and a newer version called Grok Wiki is promoted for download at grok-wiki.com.
