Trae

Trae is an AI-native integrated development environment (IDE) developed by the Chinese technology company ByteDance. It embeds large language models directly into the software development workflow, offering AI code completion, conversational debugging, and agentic modes that generate and modify entire projects from natural-language descriptions ^[1][2].

History

Trae was released by ByteDance as part of the company's push into developer tools, leveraging the AI models built by its own research teams. The editor is based on Visual Studio Code and is compatible with most VS Code extensions, allowing developers to keep their existing toolchains while adding AI assistance ^[2][5]. The product gained significant traction during 2025, particularly among developers in Asia and price-sensitive markets, aided by a generous free tier and pricing positioned below established rivals such as Cursor ^[2].

ByteDance subsequently expanded Trae with a SOLO mode, an agentic workflow that plans, writes, tests, and deploys applications from a single description, operating with its own built-in terminal and preview browser ^[4]. By 2026 Trae supported multiple frontier models — including Anthropic Claude, OpenAI GPT, Google Gemini, DeepSeek, and ByteDance's own Doubao — selectable per task ^[2][4][5].

Key Concepts

Trae combines several AI capabilities in one editor. AI autocomplete provides context-aware code suggestions as the developer types, while a chat panel allows natural-language requests such as "fix this JavaScript error," with the assistant able to inspect the workspace and apply changes ^[1][4]. Builder mode handles multi-file changes, letting users describe a feature and have the editor scaffold and edit the relevant files, similar to Cursor's Composer workflow ^[2].

The platform supports multimodal input: design mockups, Figma files, or screenshots can be attached so the model can generate matching user interfaces ^[5]. Trae also integrates with the Model Context Protocol (MCP), enabling structured interaction between AI agents, databases, APIs, and cloud services without custom connectors ^[3][6]. Model choice is user-configurable, with both cloud-hosted models and bring-your-own-API-key options available ^[3].

Applications

Trae is used for rapid minimum viable product (MVP) development, letting startups generate full-stack applications — from HTML, CSS, and JavaScript prototypes to React and Node.js projects — in hours rather than weeks ^[1][4]. Enterprises use it to build internal dashboards, chatbots, and automation tooling, while individual developers use it as a free or low-cost alternative to Cursor, Windsurf, and GitHub Copilot ^[1][2]. Its agentic SOLO mode can take a Figma design and produce a working application, including database schema, documentation, and deployment steps ^[4].
