CodecityApp's answer:
Codecademy teaches. LeetCode tests. CodecityApp builds habit. The city-building mechanic creates intrinsic motivation โ your skyline grows as your skills grow. Free forever with no meaningful limits, plus an AI mentor included. Competitors charge $20-40/month for less engagement.
CodecityApp's answer:
Self-taught developers and CS students who struggle to stay consistent with coding practice. Also bootcamp students who need structured challenge-based learning, and universities looking for supplementary practice tools for their CS programs.
CodecityApp's answer:
Built by Michael Clarke, a 50-year-old solo founder and ex-enterprise architect who got tired of boring coding practice. Every existing platform felt like homework.

CodecityApp's answer:
React, TypeScript, Vite, Tailwind CSS, Supabase (backend + auth), Anthropic API (Claude powers ARIA), Judge0 (code execution), Lovable (frontend development), EAS Build (mobile).

Interviewing.io charges $100โ225 per session. Genuinely useful, but you can't do 5 sessions a day for a month. And a stranger on a 45-minute call doesn't know your history. - Source: dev.to / 5 months ago

Interviewing is very performative so along the way you should absolutely do mock interviews just to get the nerves out and to practice being calm under pressure. I paid for several using Interviewing.io. They were certainly helpful, but I actually found the free ones I did with peers, both on interviewing.io and tryexponent.com to be more helpful. Why was it more helpful? Itโs worthwhile being on the interview... - Source: dev.to / 12 months ago
