Trae

TRAE AI is an AI-powered coding assistant and IDE designed to boost developer productivity. It offers features like AI Q&A, code auto-completion, agentic programming workflows, and advanced modes like SOLO for end-to-end project development.

TRAE AI offers both free and paid (Pro) versions. The free tier provides access to core features, while the Pro version unlocks advanced capabilities, including priority access to new models and exclusive features like SOLO mode (subject to availability and invitation).

TRAE AI prioritizes user data security. Codebase files are stored locally on your device. For codebase indexing, files are temporarily uploaded to secure servers (US, Singapore, Malaysia) to compute embeddings, after which plaintext code is permanently deleted. Chat data and telemetry can be controlled via Privacy Mode, allowing users to opt out of analytics and product improvement data collection.

No, TRAE AI is not open source. It is a proprietary tool developed by the TRAE team.

TRAE AI was developed by the TRAE team, evolving from the MarsCode plugin. It is now a standalone AI-native IDE and plugin ecosystem.

The main features of TRAE AI include AI Q&A and code auto-completion, agentic programming workflows, SOLO mode for end-to-end project development (currently in beta with limited access), one-click deployment (e.g., to Vercel), a built-in browser for previewing web apps, voice input for AI commands, custom AI agents via MCP (Model Context Protocol), and support for multiple programming languages such as JavaScript, TypeScript, Go, Rust, C++, Java, and Python.

To connect TRAE AI to a custom language model, first go to the model settings in the IDE (side chat box settings), then select "Add Model" and choose your provider (e.g., OpenAI, Anthropic, DeepSeek, Z.ai), next enter your API key, and finally validate and save. Your custom model will then be available for use.

TRAE AI supports a range of models, including native support for models like DeepSeek-V3, GPT-4o-mini, and GLM-4.6, as well as custom integration with models from OpenAI, Anthropic, DeepSeek, Z.ai, and others via API keys.

Yes, TRAE AI allows you to connect your own API keys for providers like OpenAI, Anthropic, DeepSeek, and Z.ai, giving you flexibility and control over which models you use.

SOLO mode is an advanced feature that enables end-to-end software engineering, from project planning to deployment. It is currently in beta with limited access, requiring special invitation codes even for Pro users.

TRAE AI handles data privacy by storing codebase files locally, retaining only embeddings (not plaintext) on servers, and allowing chat data and telemetry to be controlled via Privacy Mode. Users can also exclude files from context and limit telemetry collection.

You can get support for TRAE AI by reporting issues in the Trae IDE, joining the online community, or emailing feedback@mail.trae.ai for cooperation or consultation.
