DeepWiki Open — AI-Powered Wiki Generator for Code Repositories

Introduction

DeepWiki Open is an open-source tool that turns any GitHub, GitLab, or Bitbucket repository into a structured wiki. It uses LLMs to analyze code, extract architectural patterns, and produce human-readable documentation pages covering the project's design, components, and workflows. It is the self-hostable version of the DeepWiki service.

What DeepWiki Open Does

• Generates structured wiki pages from any public or private repository
• Analyzes code architecture, dependencies, and module relationships
• Supports GitHub, GitLab, and Bitbucket as source platforms
• Produces documentation with diagrams, component breakdowns, and API references
• Lets users ask follow-up questions about the generated documentation

Architecture Overview

DeepWiki Open clones the target repository, parses its file tree, and feeds code segments to an LLM through a chunking and summarization pipeline. The backend is written in Python and orchestrates the analysis across multiple passes: structure extraction, module-level summarization, and cross-reference linking. The frontend provides a wiki-style interface where each page corresponds to a logical section of the codebase. Generated wikis are cached and can be regenerated when the source repo changes.

Self-Hosting & Configuration

• Deploy with Docker Compose for a one-command setup
• Configure LLM providers via environment variables (supports OpenAI, Ollama, OpenRouter, and more)
• Set up authentication for private repository access via GitHub/GitLab tokens
• Customize output templates and wiki structure through configuration files
• Runs on modest hardware; GPU not required unless using local models

Key Features

• One-click wiki generation from a repository URL
• Multi-provider LLM support including self-hosted models via Ollama
• Interactive Q&A over the generated documentation
• Supports private repositories with token-based authentication
• Clean, navigable wiki UI with automatic section organization

FAQ

Q: Can I use DeepWiki Open with private repositories? A: Yes. Configure a personal access token for GitHub, GitLab, or Bitbucket in the environment settings.

Q: Which LLM providers are supported? A: OpenAI, Ollama, OpenRouter, Google Gemini, and any OpenAI-compatible endpoint.

Q: Does the wiki update when the repository changes? A: You can manually trigger a regeneration. Automatic sync on push events is not built in by default.

Q: How long does it take to generate a wiki? A: Generation time varies with repository size. A medium-sized project typically takes a few minutes.
