Windsurf, an AI coding agent, has introduced a new feature called Planning Mode that enables it to handle complex workflows and large projects without requiring users to break them into smaller steps. This advancement allows the AI to plan, organize, and execute entire software-as-a-service (SaaS) applications from a single prompt. Users have demonstrated the capability of Windsurf to build fully functional apps, including mindfulness apps with features like breathing timers and Pixar-style mascots, scheduling systems with Stripe subscriptions and QR event links, and various full-stack applications and internal tools. The Planning Mode represents a notable improvement in AI-assisted software development, enabling faster and more sophisticated app creation compared to traditional development teams or earlier AI agents, which showed varying levels of output quality.
