StealthCoder vs Interview Sidekick
The Interview Sidekick alternative for coding interviews
Updated June 2026
Interview Sidekick is cheap at $10 a month and covers a lot of formats, but it grew up as a prep and coaching tool and added live stealth mode later, so the part you would rely on in a real interview is the least proven. StealthCoder was built stealth-first from the start, run by an engineer in real loops, and tuned for speed in live coding and system design, with answers in under 2 seconds on the latest Claude models. If your priority is practice, Sidekick is fine. If your priority is staying invisible and fast in the live round, that is what StealthCoder is for.
Built by an engineer who got tired of paying $40 to $60 a month for a glorified ChatGPT wrapper.
