The AI coding tool market is shifting from a race for consolidation toward a model of composability. Instead of a single dominant product emerging, specialized tools are forming distinct layers that work together as a unified stack. This trend is exemplified by recent developments where Cursor provides orchestration, Claude Code and OpenAI Codex handle execution, and cross-provider plugins enable independent review.
Key points:
The emergence of an orchestration layer for managing multiple AI agents simultaneously.
An execution layer focused on the actual writing, debugging, and testing of code within terminals or sandboxes.
A new review layer that utilizes adversarial, cross-provider scrutiny to mitigate model bias and errors.
A shift in developer workflow where the text editor becomes secondary to agent management interfaces.
The move toward interoperability over vendor lock-in as companies embed tools into competitor ecosystems.
