StealthCoder vs InterviewFox
The InterviewFox alternative for coding interviews
Updated June 2026
InterviewFox keeps your shared screen clean by pushing answers to a second phone instead, which sounds safe until you realize you now spend the interview glancing down at a phone while holding eye contact. That is its own tell, and because nothing is on the interview machine, it gives you no help inside the actual IDE. It also runs about $129 a month. StealthCoder puts the solution right on the screen you are working on, invisible during the share, so you read it where your eyes already are.
Built by an Amazon engineer who cared more about not getting caught than about a flashy feature list.

Why engineers pick StealthCoder over InterviewFox
- →InterviewFox shows answers on a separate phone, so you are looking away from the camera and the code. StealthCoder surfaces the solution on the screen you are already working on.
- →Because InterviewFox output lives on the phone, it cannot help you inside the IDE on the shared screen. StealthCoder reads the problem on screen and works right there.
- →About $129 a month versus StealthCoder at $15 on the annual plan.
- →StealthCoder is keyboard-controlled and invisible during the share, no second device to juggle and no glancing-down tell.
Where InterviewFox falls short
- ✕The dual-device model means you read answers off a phone, which is a behavioral tell and breaks eye contact.
- ✕No on-screen IDE help, since nothing runs on the interview machine.
- ✕Around $129 a month, one of the pricier options.
- ✕Thin independent reputation, with most positive write-ups self-published.

Get StealthCoderWhen InterviewFox might be the better pick
If you are paranoid about anything at all touching the interview machine and you are comfortable reading from a phone, InterviewFox's air-gap approach is the most physically separated. For most people the phone glance is a bigger risk than a well-hidden on-screen overlay.
