Trae Agent — AI Coding Agent by ByteDance

Trae Agent is an open-source autonomous coding agent by ByteDance with 11,200+ GitHub stars, designed for general-purpose software engineering tasks. Give it a coding task in natural language and it autonomously plans, writes code, runs tests, and iterates until the task is complete. It supports multiple LLM providers (OpenAI, Anthropic Claude, Google Gemini, OpenRouter) and operates as a CLI tool or Python library. Part of ByteDance's Trae AI ecosystem, it brings enterprise-grade AI coding capabilities to the open-source community.

Works with: OpenAI, Anthropic Claude, Google Gemini, OpenRouter, any OpenAI-compatible API. Best for developers who want an autonomous AI pair programmer for complex coding tasks. Setup time: under 5 minutes.

FAQ

Q: What is Trae Agent? A: Trae Agent is an open-source autonomous coding agent by ByteDance with 11,200+ GitHub stars. It understands codebases, writes code, runs commands, and iterates on software engineering tasks using multi-provider LLM support.

Q: How is Trae Agent different from Aider or Claude Code? A: Trae Agent focuses on fully autonomous task completion — you describe the task and it handles planning, coding, and testing independently. Aider is more interactive (pair programming). Claude Code is Anthropic's proprietary tool. Trae Agent is open-source from ByteDance.

Q: Is Trae Agent free? A: Yes, open-source under MIT license. You bring your own LLM API keys.
