StealthCoder vs Beyz AI
The Beyz AI alternative for coding interviews
Updated June 2026
Beyz AI has a polished interface, but independent testing found the catch: it only stays hidden when you share a single tab or window. The moment you share your full screen, which is the default at most big companies, Beyz becomes visible immediately, overlay, answer text and all. It also has no free plan, leans on behavioral and mock prep, and only unlocks coding help on higher tiers. StealthCoder is built to stay invisible during full-screen share, covers coding and system design, and starts at $15 a month on the annual plan.
Built by an engineer who got tired of paying $40 to $60 a month for a glorified ChatGPT wrapper.
