Coding interviews · Open source · Free
An interview assistant should not be a closed subscription. Ofradr is an open source interview assistant: invisible overlay, mock-interview workflows, and Ultra included at $0. Source is on GitHub at sunnycodet/ofradr.
Run live coding practice, system-design notes, and agent mode without a monthly invoice.
Star github.com/sunnycodet/ofradr. The assistant is not a sealed SaaS tab you cannot inspect.
New accounts get unlimited sessions. No 15-minute free tier hiding behind a paywall.
Most “interview copilots” are Electron apps with a Stripe checkout. That model rewards lock-in, not quality. Ofradr is maintained in the open and given away because the overlay only works if people can trust it.
Use it for mock interviews, campus placement practice, and take-home rehearsal. Follow the rules of any live process you join.
Interview mode for structured problem solving. Agent mode for longer tasks. Local models when you want the session to stay on-device. Cloud models when you want the strongest APIs. All of that is Ultra, and Ultra is free.
Clone or star sunnycodet/ofradr, then install from the homepage one-liner. Create an account so Ultra is attached to your username. Follow @sunnyy050 on X for release notes.
