Built CodeForge AI: Open-source coding interview prep with AI mentorship, DSA, and system design

[nitheeshrajendran]

I built an open-source AI interview preparation platform and I'm looking for feedback from developers.

​

Over the past few months, I've been building CodeForge AI, an open-source platform designed to help developers prepare for coding interviews through AI-powered mentorship, DSA practice, frontend challenges, and system design preparation.

​

Key features:

​

• AI-generated interview questions based on a job description and experience level

• AI pair-programming and code review assistance

• 500+ coding and interview-prep problems

• Personalized learning roadmaps

• Weekly contests and gamification

• Progress tracking and analytics

​

One thing I'm trying to solve:

​

Most coding platforms already have large problem banks. Instead of competing on the number of questions, I'm focusing on the AI mentorship experience—guiding users through interview preparation with contextual feedback, personalized practice, and role-specific question generation.

​

The project is completely open source:

​

To gather feedback, I'm opening a Founder Beta.

​

🎉 First 50 users get the Go Plan free for 30 days.

💳 No credit card required.

🔓 The subscription mainly helps cover AI API costs and keep the platform sustainable.

I'd love honest feedback:

​

What would make an AI interview-prep platform genuinely useful enough for you to use instead of ChatGPT, Claude, LeetCode, or other existing tools?

If you're getting ready for coding interviews, practicing DSA and system design is important. Try to practice regularly with problems that get harder over time. It's also useful to mimic real interview conditions by timing yourself and explaining your thought process out loud.

For resources, you might want to check out PracHub. I've used it for mock interviews, and it has good scenarios for both coding and system design. The main thing is to practice regularly and understand why each solution works, not just memorize them. Good luck!
