Overview

Trae (TRAE) is an AI-native code editor from ByteDance that embeds agentic AI capabilities directly into a familiar editor and also offers TraeCode (Trae SOLO), an autonomous AI coding engineer that can plan and ship complete features from a description. It is built on a fork of VS Code, so the editing experience and extension ecosystem feel familiar, while the AI layer is deeply integrated rather than bolted on.

Trae offers a free tier (limited AI usage, plus 5000 autocompletions per month in the current plan) and paid Pro/Pro+/Ultra tiers with higher AI usage, more concurrent cloud tasks, and faster queue priority. It supports bringing your own AI models, including Claude, Gemini, and Llama, and lets you build custom agents and sub-agents that can plan, execute, and collaborate.

The agentic features include Chat for conversational coding, Builder for multi-file autonomous tasks, and a SOLO mode — a fully autonomous coding agent that can handle everything from requirements to implementation, database integration, and deployment. Agents integrate with external tools via the Model Context Protocol (MCP), and the built-in preview tab lets agents read console logs and debug in real time. Trae is a visual, AI-first editor best suited to developers who want to offload repetitive implementation work to an AI teammate while keeping visual control.

Key Features

• SOLO autonomous coding agent: delegate full development tasks from idea to implementation — planning, coding, and deploying
• Chat and Builder agents: conversational help plus multi-file, autonomous editing tasks with preview
• Custom agent framework: define your own agents with specific tools, skills, and logic; run them standalone or as sub-agents
• MCP tool integration: agents pull in external resources on demand through the Model Context Protocol
• CUE next-edit prediction: anticipates your next edit and applies smart suggestions across lines with a single Tab
• Multi-model support: bring your own models (e.g. Claude, Gemini, Llama, GPT-compatible) as available
• Familiar editing foundation: built on a VS Code fork, so the UI and extensions feel familiar

Use Cases

• AI-assisted and agentic development — generating, reviewing, and refactoring code
• Autonomous feature implementation and prototyping from natural-language descriptions
• Developers who want both IDE mode and a fully autonomous “SOLO” mode in one tool
• Teams exploring multi-agent workflows and custom AI agents
