While Cursor.so offers slight improvements over traditional IDEs and Github Copilot in terms of usability, Codex represents a completely different paradigm. While many have attempted to implement AI-driven Git development, Codex manages to maintain code specificity at a high level, making it a characteristically well-crafted OpenAI product. Personally, I've seen my commits increase several times or even tenfold after Codex compared to when Cursor appeared. The key advantage is that with proper CI/CD setup and environment secrets, it could potentially replace local development without requiring local development environment settings.
While attempts to standardize Development Environments through WebAssembly-led WebContainers or Linux Container-based Docker existed, they didn't effectively reduce the onboarding time needed for local setup. Codex shifts the focus to AI-driven development in the cloud environment - by properly configuring the development environment for AI, multiple developers can share it. This demonstrates how the no-code era of hands-free development needs AI tool development with backward compatibility.
