Trae

TRAE is an AI-native development tool for individual developers and engineering teams that covers coding, project understanding, debugging, and change management, letting you stay hands-on or delegate complex tasks to AI agents.

Key capabilities include:

• IDE mode with a familiar editor, terminal, debugging, source control, VS Code extension support, and Remote SSH/WSL development
• SOLO mode, an autonomous coding agent that plans tasks and handles code generation, testing, preview, and change summaries from natural-language or voice requests
• CUE code completion with multi-line edits, next edit prediction, smart imports, and renaming
• Custom agents and models: configure agents with prompts, MCP servers, and toolsets, choose from built-in models, or add your own via API keys
• AI code review and AI-generated commit messages, plus Privacy mode and sandboxed command execution

Available as TRAE Desktop, TRAE Web, and TRAE Mobile, with tasks synced across devices and long-running work handed off to the cloud.

Pricing: Freemium. Free ($0, Auto mode, limited usage, 5,000 autocompletions/month); Pro $20/month; Pro+ $60/month; Ultra $200/month with more usage, concurrent cloud tasks, and model early access. Enterprise plans are available through BytePlus.

Notable for evolving from the earlier MarsCode cloud IDE into a full agent-first platform; its broader TRAE Work workspace (formerly TRAE SOLO) extends the agent to research, writing, and analysis.
