Updated
An honest, in-depth review of Trae, the free AI-powered IDE by ByteDance. We explore its features, pricing tiers, performance, and critical privacy trade-offs.
A free AI code editor with access to Claude 4 and GPT-4o sounds too good to be true. Trae, built by ByteDance, makes that pitch, and for quick prototyping work, it actually delivers. But there are real trade-offs you should know about before making it your daily driver.
This review covers Trae's Builder Mode, compares it against popular alternatives like Cursor and Devin Desktop (formerly Windsurf), and digs into its privacy policy to help you decide if it is the right tool for your workflow.
What Is Trae?
Trae is a free AI-powered IDE built on VS Code by ByteDance. It launched in early 2025 and quickly gained traction as a free alternative to subscription-based AI editors, offering premium AI models, autonomous project scaffolding, and a familiar VS Code interface without a steep price tag.
The pitch is straightforward: you get AI coding assistance that rivals paid tools. However, the catch lives in the data policy.
Trae runs on macOS and Windows, with a browser-based Cloud IDE for developers who prefer not to install local applications. Linux support is planned. Since it is built on VS Code, existing extensions and keybindings carry over seamlessly, making the learning curve minimal.
2026 Update: Trae has released SOLO, a standalone application (desktop and web) that no longer requires the IDE plugin. SOLO features two modes: Code (the agentic coding loop) and MTC (More Than Coding) for broader product work. Pricing is structured around a token-based Basic + Bonus usage model rather than flat request caps.
Key Features
Builder Mode
Builder Mode is an autonomous agent that takes a natural language description and scaffolds a complete project—including frontend, backend, and configuration files.
By describing a prompt (e.g., "build me a task management app with auth and a dashboard"), Builder Mode generates the file structure, writes the code, and connects the services. For prototyping and MVPs, it is highly efficient, scaffolding a full React + Express app with functional routes in minutes.
However, limitations appear on larger, more complex projects. Builder Mode works best when starting from scratch with a clear, contained scope. When tasked with adding features to an existing codebase with custom patterns, it can struggle with context drops, repeated instructions, or overwriting unintended files.
Multimodal Input
By uploading a screenshot, mockup, or design file, Trae can generate matching UI code. This is useful for converting design exports or wireframes into functional components. The output quality varies: simple layouts are clean, but complex responsive designs generally require manual adjustment.
AI Models
Trae offers access to several prominent AI models:
- Claude Sonnet 4 and GPT-4.1 (Premium)
- DeepSeek R1 and Gemini 2.5 Pro (Advanced)
Model access is metered by Basic + Bonus token credits. The Free tier covers light experimentation, while daily developers will likely require a paid plan to handle heavier usage.
Cloud IDE
Trae's Cloud IDE runs entirely in the browser with one-click deployment. This is useful for quick experiments or working from alternative devices. Performance is stable for small projects but can lag on larger codebases.
MCP Support and Custom Agents
Trae supports the Model Context Protocol (MCP) for connecting external tools and APIs. You can also configure custom agents with specific tools, skills, and logic to build repeatable AI workflows.
Pricing Breakdown
Trae utilizes a token-based pricing model. Usage is metered as Basic + Bonus token credits instead of fixed fast/slow request caps.
| Plan | Price | Features |
|---|---|---|
| Free | $0 | 5,000 autocompletions/month, limited Basic usage, standard queue, 2 concurrent cloud tasks, limited SOLO mode |
| Lite | $3/mo | $5 Basic usage + Bonus, unlimited autocomplete |
| Pro | $10/mo | $20 Basic usage + Bonus, full SOLO mode, 7-day free trial |
| Pro+ | $30/mo | 3.5x Pro usage |
| Ultra | $100/mo | 20x Pro usage, early model access |
SOLO mode is included on all paid plans with limited access on the Free tier. There is currently no enterprise tier with dedicated administrative controls, SSO, or custom compliance certifications.
The Privacy Question
Before adopting Trae, it is important to review its data privacy policies. The telemetry collection is extensive, and there are specific conditions regarding data handling:
- Personal data retained for 5 years after account closure.
- Non-personal data retained indefinitely.
- Data shared with affiliate companies and service providers.
- Persistent connections to multiple external domains even when the editor is idle.
- No privacy mode, no telemetry opt-out option, and no local-only execution mode.
- No documented SOC2, ISO, or similar security certifications.
Trae states that it does not perform secondary training on user code. However, the telemetry settings cannot be disabled.
For hobby projects, open-source work, or learning exercises, this may be acceptable. For proprietary code, client work, or sensitive enterprise projects, developers should weigh these terms carefully. If local-only privacy is a strict requirement, alternative editors like Void or PearAI (using your own API keys) may be more appropriate.
Trae vs. Cursor vs. Devin Desktop
Below is how Trae compares to other prominent AI IDEs:
| Feature | Trae | Cursor | Devin Desktop (formerly Windsurf) |
|---|---|---|---|
| Price | Free / $10/mo | Free / $20/mo | Free / $15/mo |
| Free Tier | 5,000 completions + limited premium | 50 premium requests | 25 credits/month |
| Agent Mode | Builder Mode (project scaffolding) | Composer (multi-file agent) | Cascade (multi-step agent) |
| Codebase Indexing | Basic | Deep (repo-wide) | Medium (Cascade context) |
| Models | Claude 4, GPT-4o, DeepSeek R1, Gemini 2.5 Pro | Claude, GPT, custom | SWE family + others |
| Privacy | Telemetry enabled, no opt-out | Zero Data Retention available (paid) | Zero Data Retention default (Teams+) |
| Enterprise | None | Yes (SSO, RBAC) | Yes (SOC2, self-hosted option) |
| Base Platform | VS Code fork | VS Code fork | VS Code fork |
- Choose Trae if: You need a highly capable, budget-friendly IDE with premium model access for side projects, quick prototypes, or learning.
- Choose Cursor if: You work on production codebases that require deep repo-wide indexing, reliable multi-file editing, and enterprise security options.
- Choose Devin Desktop if: You want a balance of multi-step agent flows (Cascade) and alternative privacy controls.
Real-World Performance
Builder Mode is highly effective for greenfield projects. It generates runnable code quickly and reduces boilerplate setup times for simple landing pages or CRUD applications.
However, there are performance trade-offs to keep in mind:
- Context Retention: During long editing sessions, Trae can lose track of earlier instructions, requiring you to re-explain the project structure or specific patterns.
- Large Codebases: Without deep repository-wide indexing, AI suggestions can become less relevant on projects containing dozens of files.
- Error Recovery: When generated code contains bugs, follow-up fixes can sometimes introduce new issues rather than resolving the core error.
- No Offline Mode: The AI features require an active internet connection to communicate with backend servers.
Community feedback indicates that Trae is excellent for rapid prototyping, but less consistent for complex, enterprise-scale production codebases.
