Built with Trae?
Let's make sure it's production-ready.
ByteDance's AI-powered IDE that serves as a free alternative to Cursor, with strong support for full-stack application generation using React, Vue, and Python. Particularly capable at UI component generation and layout. We help non-technical founders identify and fix the issues AI tools leave behind.
Common issues we find in Trae code
These are real problems we see in Trae projects during our audits — not hypotheticals.
Chinese-language comments and variable names in generated code
Trae occasionally generates inline comments or even variable names in Chinese, particularly for UI-related code, which creates readability issues for teams that operate in English and can complicate code review.
Missing authentication on generated API routes and backend endpoints
Like many AI code generators, Trae creates backend routes without authentication middleware, leaving all endpoints publicly accessible. This is a critical issue for any app handling user data.
Inconsistent coding style across components in the same project
Trae may switch between different state management patterns (useState vs. Pinia vs. Vuex), component styles, or file organization conventions across files in the same generation session, requiring normalization before merging.
Error handling in generated code is immature compared to more established tools
As a newer tool, Trae's error handling patterns are less consistent than Cursor or Copilot — generated code often omits catch blocks on async operations and lacks UI feedback for error states.
Generated Tailwind CSS classes are not responsive by default
Trae's UI generation produces desktop-first layouts without mobile breakpoints. The generated Tailwind classes are rarely prefixed with responsive variants like `sm:` or `md:`, requiring manual responsive design work.
No test configuration or test files generated with application code
Trae does not scaffold testing infrastructure or generate tests alongside components and API routes, leaving the entire project without coverage from the start.
Generated Python backends lack production WSGI/ASGI configuration
Python backends generated by Trae run with Flask's or FastAPI's development server but do not include Gunicorn, Uvicorn, or Docker configuration needed for production deployment.
API keys sometimes included in frontend bundle via environment variables with wrong prefix
Trae-generated Vue and React code sometimes references server-side environment variables in client-side code, which would expose secrets in the browser when using Vite's VITE_ prefix convention.

Frequently asked questions
Is Trae actually free and what are the limitations for startup use?
Trae is currently free during its beta period from ByteDance. The main limitations for startup use are maturity — it is a newer tool with less community knowledge around its edge cases, and the occasional non-English output in generated code. For production use, plan for thorough code review of everything it generates.
How do I handle Chinese comments that Trae generates in my code?
You can instruct Trae explicitly in your prompts to generate all comments and identifiers in English. Add a system-level instruction like 'All code comments must be in English' at the start of your session. For code already generated, a global search-and-replace pass followed by a review is the fastest cleanup approach.
How does Trae compare to Cursor for a team that wants a free AI coding tool?
Trae is the closest free alternative to Cursor's feature set, offering inline editing, chat, and project generation. Cursor has a more mature ecosystem, better codebase context awareness, and more consistent output quality. Trae is a strong choice for early prototyping and solo developers; Cursor is worth the cost for teams shipping production code.
Does Trae support Vue 3 with the Composition API or only Options API?
Trae supports both, but defaults to the Composition API for Vue 3 projects. You can specify in your prompt which pattern you prefer. The Composition API output tends to be cleaner and more consistent with modern Vue practices when using Trae.
What security steps are mandatory before deploying a Trae-generated app?
Before deploying, add authentication to all API routes, move any credentials to server-side environment variables, add input validation with a library like Zod or Pydantic, and enable CORS restrictions. Trae-generated backends are development-grade and need these additions before handling real user data.
