In 2025, as AI models increasingly automate code generation and deployment, developers encounter new challenges in safely executing code they did not author, leading to the rise of sandboxes as vital infrastructure. Sandboxes provide secure, isolated environments for testing, validating, and monitoring AI-generated code, preventing risks to production systems and supporting workflows like reinforcement learning and web interaction. Platforms such as Koyeb are highlighted for their serverless container capabilities, offering strong isolation, CI/CD integration, and cost-effective, pay-as-you-go pricing, making them ideal for transitioning AI-generated prototypes to production-ready environments. Koyeb's platform excels with features like secure isolation, autoscaling, and global deployment options, positioning it as a leading choice for developers seeking reliable, scalable, and safe execution of AI-generated code.
