# Bugdr > Bugdr is a developer training platform where engineers fix real production > bugs from open-source repositories. Unlike LeetCode-style algorithm > puzzles, Bugdr presents actual bugs that were found and fixed in real > codebases — the same kind of bugs engineers encounter on the job every day. ## What Bugdr is - A coding practice platform focused on real-world bug fixing - Problems are sourced from real GitHub pull requests (merged bug fixes) - Engineers read a buggy codebase, reproduce the bug, and submit a fix - Difficulty levels: Easy, Medium, Hard, and "Get a Job" (staff-level) - Career paths: Frontend, Backend, Full Stack, Mobile, DevOps/Infra - Points and rankings based on bug difficulty ## Who it is for - Junior and mid-level engineers who want to level up to senior/staff - Self-taught developers building a portfolio of real debugging experience - Engineers preparing for technical interviews that include debugging rounds - Anyone who finds LeetCode unrealistic and wants to practice on real code ## How it works 1. Browse open bug problems by difficulty and category 2. Get the buggy codebase (standalone, no setup required) 3. Reproduce the failing test, fix the bug, submit your solution 4. Automated checks verify the fix against hidden tests 5. Earn points and climb the leaderboard ## Links - Website: https://bugdr.app - App: https://app.bugdr.app
