Trae is a free AI-powered code editor developed by ByteDance that provides unlimited access to frontier AI models including Claude and DeepSeek for code generation, completion, and chat-based development assistance. It solves the problem of AI code editor pricing by offering premium AI capabilities at no cost, lowering the barrier to entry for developers who want to experiment with AI-assisted coding. Launched in January 2025, Trae is built on the VS Code foundation and supports most VS Code extensions and settings.
Trae operates in two primary modes: Builder mode for zero-to-one application development where developers provide natural language specifications and Trae generates complete applications with proper file structure and implementation code, and Chat mode for analyzing existing code, answering questions, and providing real-time recommendations. The editor includes AI code auto-completion, terminal suggestions that can paste or execute commands directly, MCP integration for connecting to external tools, and SSH/WSL support for remote development. Trae supports importing existing VS Code settings and extensions, making migration straightforward for developers already in the VS Code ecosystem.
Trae targets developers who want powerful AI coding assistance without paying subscription fees, making it particularly attractive for students, freelancers, indie developers, and those in regions where AI tool subscriptions are less accessible. It is suitable for web development, full-stack projects, and rapid prototyping with its Builder mode. However, developers should be aware of the data collection practices associated with ByteDance products and evaluate whether the privacy trade-offs are acceptable for their use case, particularly when working with proprietary or sensitive codebases.
