CodePlanet

CodePlanet is trying to be the entire stack — leetcode grinding, cloud IDE, portfolio builder, job board — all in one free platform, which is either genius or a case of trying to do too much too fast. With 11K+ problems available and only 56 users onboard, you'd be building in public with basically no community yet, so that's the trade-off to consider if you're looking for that network effect. The AI mentorship plus developer profile with stats is the hook here, but honestly I'd wait a few months to see if this gains real traction before investing time.
