Trae

Download Trae from its Download Center, or open TRAE Web, and sign in. Projects live in one workspace, and you start a task by describing it to an agent, using @ to add context and / for commands and skills.

In Agent Mode, Trae plans the work, picks its tools and executes. Agents read your repositories, search the web and the documents you share, and follow rules you write. Through the Model Context Protocol they reach external resources, and a built-in preview tab lets them interact with page elements, read console logs and debug a running app.

• •SOLO Agent - Trae's most advanced coding agent takes delegated tasks from requirements to implementation, showing what it is doing so you can step in.
• •Custom Agents and Sub-Agents - Built-in agents cover common tasks, and you can create your own by defining their tools, skills and logic, run them alone or as sub-agents, and share or discover community-built agents.
• •Agent Mode and IDE Mode - Orchestrate agents across projects, then switch to a full editor for in-depth editing and precise debugging without leaving the task.
• •Context, Rules and Tools - Agents draw on your code, web search and your documents, follow custom rules, connect to tools through MCP and inspect a live browser preview while debugging.
• •CUE Next-Edit Prediction - Autocomplete that anticipates your next change and applies multi-line suggestions with Tab; 5,000 completions a month on the free plan, unlimited on paid plans.

Trae suits developers who want an AI-first editor that also runs agent work, instead of pairing a separate agent with a traditional IDE. Beginners can build a demo step by step in Agent Mode, while experienced developers can run agents across projects in parallel and drop into IDE Mode to take the controls.
