StealthCoder vs Cluely
The Cluely alternative for coding interviews
Updated June 2026
Cluely is a general cheat-on-everything overlay, not a coding-interview tool, and it comes with real baggage. In 2025 it exposed more than 83,000 users' meeting transcripts and screen captures after leaving an admin password in a public repo, and in 2026 its CEO publicly admitted the widely quoted revenue figure was a lie. Screen-share invisibility is locked to its $75-plus tier, not the $20 plan. StealthCoder is purpose-built for coding and system design, invisible during the share by default, and built around storing no data.
Built by an engineer who passed his own loop with this and refused to ship anything he wouldn't run himself.
