This update is a massive win for app creators who want to build secure, mobile-ready software without dealing with complicated setup tools. It matters most to paid users who are building real-world apps, giving them AI-powered security and the ability to build and test phone apps straight from their web browser.
What's new
- AI Security Agent: Think of this as a smart robot security guard for your code. Instead of just checking the outside tools your app uses, it reads your entire project to find weak spots hackers might exploit. When it finds problems, it organizes them into tasks so Replit's AI can fix them all at once.
- Automatic Vulnerability Patching (CVE Auto-Protect): When a major security flaw is found in a tool your app relies on, this feature automatically writes a fix in the background, tests it to make sure it doesn't break your app, and asks for your approval to apply it. You get security fixes in minutes instead of having to hunt them down yourself.
- Mobile Previews in the Browser: If you're building a phone app, you no longer need to download heavy software like Xcode or Android Studio. You can now run a fake iPhone (iOS Simulator) or Android (Android Emulator) right inside your web browser to tap around and test your app. Any code changes you make instantly update on the screen.
- Plaid Bank Connection: You can now easily link your app to over 12,000 real banks and financial services using Plaid. This lets the people using your app safely log into their bank accounts, meaning you can build things like budget trackers or portfolio apps with real, live money data.
Improvements
- Upgrading Older Projects: If you started a project a while ago, it used to only support one main piece of content (like a single website). Now, you can add extra pieces—like a mobile app or a slide deck—to those older projects. Replit does this without changing your web address, losing your secret passwords, or messing up your live app.
