Replit — Secure Vibe Coding Made Simple

As vibe coding revolutionizes app development, security can't be an afterthought—it needs to be a core part of the creation process. Recent Stanford research shows that developers using AI assistants wrote less secure code in 80% of tasks compared to those coding manually, while being 3.5 times more likely to overestimate their code's security. And that's professional developers, we've seen an even more concerning trend among vibe coded apps. At Replit, we don't just take this seriously, we build security into every app you create with Agent, by default—something Replit CEO Amjad Masad has called "the Pit of Success". That's why our apps are secure, by default. We bake security in to the process of building with Agent—so you can focus on creating.
