In domestic and international editions...
TRAE plays a differentiated card in the AI IDE space: the domestic version is completely free, and the international Pro plan costs just nth — half the price of Cursor. The international Pro version supports top-tier models including Claude, GPT, and Gemini, with 600 fast-queue requests per month. The SOLO official release (November 2025) introduced multi-agent collaboration and Plan mode, evolving from conversational coding to planned development, with a three-panel layout for intuitive multi-task management. Compared to Cursor and Copilot, TRAE has a natural edge in Chinese programming — noticeably higher accuracy in understanding Chinese instructions. Especially suited for domestic developers, cost-conscious indie developers, and teams that need Chinese-language coding — zero cost to get started with the domestic version, while the international Pro delivers an AI coding experience close to Cursor Pro at half the price.
TRAE is an AI-native IDE developed by ByteDance, built on VS Code architecture. It comes in domestic and international editions: the domestic version offers free access to Doubao-1.5-pro and DeepSeek/V3 models, while the international version provides a free tier with limited quota and a Pro plan (nth) with access to Claude, GPT, Gemini and other premium models. Core features include SOLO mode (end-to-end autonomous development), Builder mode (full project generation), multi-agent collaboration, design-to-code conversion, and Chinese natural language programming. SOLO was upgraded to its official release in November 2025.
Difficulty: Beginner Friendly
SOLO End-to-End Autonomous Development
SOLO mode supports end-to-end autonomous development from PRD analysis to coding, testing, and deployment. Plan mode creates a development roadmap before execution to avoid misdirection. Can orchestrate multiple sub-agents for collaborative work, including refactoring assistants and performance optimizers.
Builder End-to-End Project Generation
Describe requirements through a visual interface to auto-generate complete project code. Supports frontend and backend code generation with real-time preview, enabling one-click transformation from idea to running project.
Design-to-Frontend Code Conversion
Directly converts design files into responsive frontend code, significantly reducing slicing and restoration work in frontend development. Supports mainstream design formats and generates standards-compliant usable code.
Chinese Natural Language Programming
Deeply optimized for Chinese instruction comprehension — describe requirements in Chinese to generate corresponding code. Powered by Doubao and DeepSeek, delivering higher accuracy in Chinese semantic understanding than English-first competitors.
Multi-Agent Collaboration
Supports both manual and intelligent creation of custom agents. Multiple agents collaborate on complex tasks — one for coding, one for testing, one for documentation — enabling parallel development workflows.
Rapid App Development for Beginners
Programming beginners use SOLO mode to describe desired applications in Chinese, and TRAE automatically handles everything from code generation to project setup. Builder mode supports visual operations, lowering the technical barrier.
Rapid Design Implementation
Frontend developers import design files into TRAE for automatic responsive frontend code generation. Combined with real-time preview, design implementation efficiency improves several times over.
Full-Stack Rapid Prototyping
Use SOLO Plan mode to design overall architecture first, then have multiple agents collaboratively complete frontend and backend code. Time from requirements to demonstrable prototype compressed from days to hours.
Legacy Code Understanding & Refactoring
Quickly understand code logic and architecture of unfamiliar codebases through conversation. Deploy refactoring agents for safe large-scale code transformation.
TRAE has domestic and international editions. The domestic version (trae.com.cn) is currently free, supporting Doubao and DeepSeek The international version (trae.ai) offers Free and Pro tiers: Free includes 10 premium model fast-queue requests and advanced model requests per month; Pro at nth provides 600 fast-queue requests per month with unlimited slow-queue and advanced model access.
Both are AI IDEs built on VS Code architecture. Key differences: 1) TRAE international Pro is nth vs Cursor Pro at nth — half the price; 2) TRAE has better Chinese programming experience, with the domestic version being completely free; 3) TRAE offers Builder visual mode and design-to-code features; 4) Cursor has a more mature Agent mode, Background Agent, and ecosystem. The choice depends on budget, language preference, and specific needs.
Built on VS Code architecture, TRAE theoretically supports all programming languages that VS Code supports, including Python, JavaScript, TypeScript, Java, Go, Rust, and more. AI features work best with mainstream languages.
SOLO mode is better for experienced developers, supporting the full PRD to coding to testing to deployment workflow with complex multi-file operations and refactoring. Builder mode targets a broader audience, generating projects from visual requirement descriptions with a lower barrier to entry.
