Introduction

Trae SOLO is ByteDance's autonomous coding mode shipped inside the free Trae IDE. You describe a project, SOLO breaks it into tasks, generates files, runs the tests, and iterates until done — closer to Devin than Cursor in spirit. Best for: solo developers prototyping side projects without subscribing to Claude or Cursor Pro. Works with: Trae IDE on macOS / Windows. Setup time: 5 minutes (download + sign in).

What's in Trae SOLO

Component Behavior
Task planner Breaks the user's high-level goal into ordered tasks before any file is touched
Multi-file editor Edits and creates files based on the plan, with rollback if a test fails
Self-test loop Runs npm test / pytest / language-detected tests after each change
Approval gates User reviews planned changes; SOLO waits for approval before destructive ops
Free tier Backed by Claude Sonnet / GPT-4o; no per-token billing for users

Example session

You: "Build a Pomodoro timer web app — React, Tailwind, dark mode toggle, sound on completion."

SOLO plan:
  1. Initialize Vite + React + Tailwind project
  2. Create Timer component with start/pause/reset
  3. Add sound asset and Web Audio API trigger
  4. Add dark mode toggle with system preference detection
  5. Write Vitest specs for timer state transitions

[reviews plan, approves]

SOLO executes:
  Step 1: Created package.json, tailwind.config.js, src/main.tsx
  Step 2: Created src/components/Timer.tsx (87 lines)
  Step 3: Added public/bell.mp3, src/hooks/useSound.ts
  ...

  All 5 steps complete. 4/4 tests passing. Run with: npm run dev

Why ByteDance ships this for free

Trae is ByteDance's bet on the AI-coding stack outside China — competing with Cursor and Windsurf for English-speaking developers. SOLO is the free hook. Pricing for premium models (longer context, faster inference) comes later.

FAQ

Q: Is Trae SOLO really free? A: Yes — Trae IDE and SOLO mode are free as of 2026. ByteDance subsidizes the Claude / GPT inference cost. No credit card needed for the free tier.

Q: Is my code private if I use Trae? A: Trae's privacy policy states code stays private and is not used for model training. Verify on trae.ai/privacy before using on sensitive codebases.

Q: How does SOLO compare to Cursor's Composer? A: Cursor Composer is interactive — you guide each multi-file edit. SOLO is autonomous — you give a goal, it iterates to completion. Closer to Devin / Cline / Roo Boomerang than to Cursor.

Quick Use

  1. Download Trae IDE from trae.ai (macOS or Windows)
  2. Sign in with email or Google
  3. Click the SOLO mode toggle in the chat panel; describe your project goal
