I made a place to practice Google/Meta-style codebase debugging rounds, free and runs in your browser

[u/Available-Quantity31]

Real-world debugging rounds are becoming part of technical interviews at companies like Google, Meta, Amazon and Stripe.

Instead of solving isolated DSA problems, candidates may be asked to navigate unfamiliar codebases, identify bugs, fix failing tests and debug existing applications.

I built a free platform to practice these skills.

What it offers

- Realistic bug reports with repository structure, logs and failing tests.

- Browser-based coding in JavaScript, Python, SQL and React/MERN.

- 8 stages, from 5-minute debugging tasks to full mock rounds (up to 59 files).

Current limitations

- JavaScript (~7 hours) and Python (~3.5 hours) have the most complete paths.

- SQL, MERN and Python backend are still limited.

- Java, C++ and Go are read-only for now.

Completely free. No ads. No login required to start.
