CodeVault — LeetCode & Codeforces to GitHub

CodeVault automatically turns your LeetCode and Codeforces practice into a clean, organized GitHub portfolio — with zero manual work after setup. WHAT IT DOES • Detects your accepted submissions on LeetCode and Codeforces • Pulls the exact accepted source code — not whatever's currently in the editor • Organizes LeetCode solutions by topic, Codeforces solutions by rating • Generates a metadata.json, README.md, and version history for every problem • Commits and pushes everything to your own GitHub repository, automatically • Keeps a running dashboard: streaks, solve counts, language and topic breakdowns • Skips duplicates — re-solving a problem adds a dated history entry instead of a mess HOW IT WORKS Rather than scraping the page you're looking at (which breaks the moment a platform tweaks its UI), CodeVault polls each platform's own submission APIs in the background — so it keeps working even when you don't have a tab open, as long as you're logged in. YOUR DATA STAYS YOURS CodeVault connects to GitHub using OAuth's Device Flow — no password, no Personal Access Token, ever. There is no CodeVault server: your code goes straight from your browser to your own GitHub repository, and nowhere else. CHOOSE YOUR PACE Run it fully automatic on a timer, or flip to manual mode and sync only when you click "Sync Now." SETUP 1. Register a free GitHub OAuth App (guided, ~2 minutes) and connect 2. Pick or create a repository 3. Add your Codeforces handle (LeetCode needs no setup — it uses your logged-in session) 4. Solve problems as usual — CodeVault takes it from there Perfect for anyone building a public problem-solving portfolio, tracking their DSA practice for interview prep, or just tired of manually copying accepted solutions into a repo.
