Repo Explainer
I built RepoExplainer to quickly understand unfamiliar codebases without cloning them locally. What it does: Paste any public GitHub repo URL and get an AI-generated explanation with architecture diagrams, directory structure, and tech stack breakdown. How it works: FastAPI backend fetches the repo's directory tree and key files (README, package.json, etc.) in parallel from GitHub's API, then sends that context to Claude for structured analysis. Try it: https://repex.thienbao.dev. Tech highlights: - Parallel file fetching with asyncio.gather (70% faster than sequential) - Smart…

What it does
Explore any GitHub repo online in seconds. No cloning, no local setup, no wiring an AI tool yourself. Paste the URL; we fetch the repo, run agentic AI exploration, and give you a thorough analysis: overview, architecture, tech stack, and tailored answers to your instructions. One place, zero friction.
Paste a GitHub repo URL and get an instant AI explanation: architecture diagram, tech stack, and directory structure. Understand any codebase in minutes.
Paste a GitHub repo URL and Repo Explainer returns an architecture diagram, the tech stack, and an annotated directory tree, then answers follow-up questions about the code. This app requires JavaScript to run. Enable JavaScript to explain a repository, or view the source on GitHubfrom repex.thienbao.dev

RepoIQ2025 · repoiq.be · ▲15After years of struggling with onboarding to new projects, I got tired of spending weeks just trying to grasp the basics of a codebase. The README rarely tells the whole story, and "just read the code" isn't practical for large repos. I built RepoIQ to create personalized learning paths through any GitHub repository. It analyzes the codebase structure, identifies key components, and creates a step-by-step guide tailored to your learning needs.

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
