Unlike chat-based IDEs, you're never blocked waiting for responses. Permission Profiles Agent Assisted (Recommended) - Balanced automation with oversight Agent Driven - Maximum autonomy, minimal interruptions Review Driven - Review every artifact and command Artifacts System Agents prove their work with task plans, implementation plans, code diffs, screenshots, browser recordings, and test results. Review artifacts, not raw code. Browser Agent Testing Automated QA: Browser agents click buttons, test inputs, validate functionality, and record everything—no manual dev mode testing required. 💡 DEMOS IN THIS VIDEO Demo 1: Google News Extraction Browser agent autonomously navigates, extracts headlines, and returns screen recording. Demo 2: Pomodoro App Build Single prompt → full app with Vite, timer logic, styling, task list, comprehensive browser testing, and walkthrough documentation. Demo 3: Space Invaders PRD Agent generates complete Product Requirements Document, showing planning and artifact capabilities. 📚 RESOURCES 🌐 Website & Newsletter: https://snapperai.io 🐦 X (Twitter): https://x.com/SnapperAI 💬 Questions?
