Trae AI

Trae AISince 2026-08

Trae AI is a next-generation, AI-native integrated development environment (IDE) built from the ground up to transform software development. Powered by state-of-the-art models (Claude 3.7 Sonnet and GPT-4o), Trae combines deep codebase indexing with proactive agentic capabilities that assist in writing, debugging, and refactoring full-stack applications. Featuring an interactive Builder mode, Trae analyzes entire project architectures, executing multi-file edits, running terminal commands, and validating builds autonomously.

Trae bridges the gap between conversational coding and hands-on IDE ergonomics. Its Builder Mode allows developers to prompt complex application changes—such as integrating OAuth authentication or migrating database schemas—while Trae drafts diffs, runs tests, and applies code across multiple files. With seamless VS Code extension compatibility, zero-config workspace indexing, and free access to premier models, Trae represents a major leap in developer productivity.
