StealthCoder vs UltraCode AI
The UltraCode AI alternative for coding interviews
Updated June 2026
UltraCode AI asks for a single non-refundable payment, commonly around $899 and anchored as high as $1,799, with no free trial. A reviewer testing it found the app icon stayed visible in the Windows taskbar during screen share, which is exactly the kind of tell that gets you caught. StealthCoder is $15 a month on the annual plan, comes with a 7-day free trial, runs on Mac and Windows, and is built to leave nothing visible. You risk a few dollars instead of nearly a thousand on a tool you cannot test first.
Built by an engineer who passed his own loop with this and refused to ship anything he wouldn't run himself.
