Repository import from GitHub
Accepts a GitHub repository URL and performs a shallow clone of the target branch to analyze the active codebase state.
GitDecode
GitDecode is a GitHub codebase analysis tool with AST-backed graphs, interactive diagrams, and natural-language answers to understand structure and impact.
Overview
GitDecode is a developer tool for understanding GitHub codebases by turning repository structure into an AST-backed graph, interactive diagrams, and natural-language answers. It is positioned for engineers who need to inspect how code is organized, how dependencies connect, and where changes may propagate.
The product imports a repository from GitHub, detects the workspace layout, and parses code into syntactic units before compiling call and import relationships into a graph. From there, users can explore the codebase visually or ask questions about specific files and behavior, with the product emphasizing private, in-memory processing and transient storage of source code.
Core capabilities
AST-based codebase graph
Parses files into AST blocks and builds a multi-file import and call dependency graph rather than relying on text chunking.
Vectorless graph RAG
Uses graph BFS routing for retrieval, with depth-based context loading tied to source files and signatures.
Interactive visualization
Generates interactive architecture diagrams and visual graph views for exploring repository structure.
Chat-based code exploration
Supports natural-language questions about code, with answers grounded in repository structure and call relationships.
Blast-radius analysis
Provides impact analysis that traces direct and transitive dependents when a file changes.
Common use cases
Onboard to an unfamiliar codebase
Use GitDecode to get a structural map of a repository before making changes, so you can see how modules, imports, and call paths fit together.
Trace implementation details
Ask repository-specific questions in natural language when you need to locate where authentication, routing, or other behavior is implemented.
Assess change impact
Review the blast radius of a proposed edit by checking which direct and transitive dependents may be affected.
Explore architecture visually
Browse interactive diagrams and graph views when you want a visual overview of architecture instead of reading files one by one.
Analyze private or larger repositories
Use the paid or enterprise plans when you need private repository analysis, higher-scale use, or custom deployment options.
Pros and Cons
Pros
- Builds structural understanding from ASTs and dependency graphs instead of plain text chunks.
- Offers multiple ways to inspect a codebase, including diagrams, chat, and impact analysis.
- States that code is processed in memory and deleted after analysis, with no persistent source copies.
- Provides clear plan options for public repositories, private repositories, and enterprise deployment needs.
- Supports a broad set of languages, including TypeScript, JavaScript, Python, Go, Rust, C++, Java, Ruby, PHP, and Swift.
Cons
- Evidence for integrations beyond GitHub and LLM key support is not provided on the collected pages.
- The product page does not spell out a full onboarding flow beyond repository URL import and GitHub authentication.
- Team-collaboration features are not described in the available source text, aside from private workspace handling and enterprise support.
FAQ
Does GitDecode work with public and private repositories?
GitDecode works with GitHub repositories. The home page highlights free use for public repos, while the pricing page says the Developer plan supports public and private repositories.
Does GitDecode store source code after analysis?
The home page says code is processed in memory and not stored, and the security page adds that full file contents are cloned to volatile disk, processed, and deleted after AST extraction. The pricing page also states that source code is processed in transient memory and not persisted.
How do users sign in?
The home page describes GitHub auth, and the security page says requests are protected with Supabase JWT verification. The pricing page notes that public repo use does not require a credit card and the product supports secure sign-in through GitHub authentication.
What does GitDecode produce from a repository?
GitDecode outputs interactive diagrams, a codebase knowledge graph, chat-based answers, and impact analysis views. The how-it-works page shows a pipeline that imports a repo, parses ASTs, compiles a graph, routes queries through graph-based RAG, and streams results to the interface.
What plans are available?
The pricing page lists a free Hobby plan for public repositories, a paid Developer plan for active engineers, and an Enterprise plan with custom deployment, self-hosting, and SLAs.
