Claude can now reverse-engineer and rebuild apps like TradingView and OBS without source code

X user Prajwal Tomar reports that Claude (Opus 5.5) can now rebuild apps just by studying them — no source code needed. People are already using it to clone TradingView, Screen Studio, and OBS. A referenced article lays out three workflows: mapping unknown repos, rebuilding undocumented APIs, and decompiling binaries, leveraging the model's 1M-token context window. Tomar, who runs an app studio, argues that when anyone can copy an app, the only ones worth paying for are those where teams genuinely care about polish and feel — the era of shipping a basic to-do app and getting users is over.
