About this tool
Fake DevTools Intrusion is a free online fake screen simulator. F12 console filled with red errors and malicious logs. Prank your friends with convincing fake screens. It runs entirely in your browser — no download or sign-up needed.
After opening it, it simulates the scene where the browser developer tools were invaded: the Console panel scrolling crazily with red errors, the Network panel swipes abnormal requests, and the Sources panel pops up with code injection warnings. The three panels are "out of control" simultaneously, looking like a website being attacked. Real-time operation. The error density and content can be customized, and a series of "suspicious requests" directed to real sites can even be forged.
All output is an illusion created by front-end scripts and will not actually modify any page code, send any requests, or affect the operation of the website; it will resume when the panel is closed. If you want to act more like it, you can press F12 and pretend to "accidentally open the developer tool", and then "exclaim" with the words "Where did this mistake come from" to make the scene more exciting.
It is suitable for teasing front-end or full-stack programmers-the moment of "Is your website injected by someone?" is the most shocking; it is also often used as a video screen for security demonstrations or a hacking scene in movies and movies, allowing the technical audience to get into the drama at a glance.
Reminder: Use caution with caution to colleagues who are changing code online, which may easily lead to real investigation actions; choose friends who are chatting and relaxing, and immediately expose and show the page code intact after the performance, and talk about real front-end security common sense.
The fake developer tool intrusion caused the browser's console, network and source code panel to "fall" at the same time. Red error reports and injection warnings flew together, and programmers felt nervous.
