Made a free alternative to Hello Interview's guided practice (no paywall, all problems unlocked)

Do you ever want to use Hello Interview’s guided system design practice, but it only lets you do 1 problem for free and locks the rest behind premium?

Well… I built a mini version of that, and it’s completely free.

Right now it supports:

• Functional Requirements
• Non-functional Requirements
• API Routes

( HLD + diagrams are under construction )

Just submit the question you want to solve, and the platform guides you step-by-step, just like Hello Interview. The AI feedback uses Hello Interview blog content as context, so the analysis feels very close to their guided mode.

No login, no limits. Just try and break it.

Give it a try & tell me what to improve!

If you have feedback or want to contribute, drop it in the comments, happy to collaborate. 🚀
