What it is and who it is for

In one sentence: ByteDance’s AI development and task product, accessed through editor and workspace interfaces.

Who it suits: Users who want a visual development environment and delegated project tasks.

What you can do:

• Understand, complete, and edit code in an editor.
• Delegate planned multi-step tasks.
• Work with project material and outputs in a workspace.

Where to start: Download and sign in through TRAE. Check account and entitlements separately for regional editions, then open a test project.

Cost: The commercial product has free and paid tiers; the open-source Trae Agent uses separately billed model APIs.

Access and setup: your first session

Download and sign in through TRAE. Check account and entitlements separately for regional editions, then open a test project.

Trae Agent is a separate open-source research/development CLI using trae-cli; it is not the commercial desktop installer.

A concrete task and how to check it

Ask for structure and startup instructions before fixing a small reproducible issue.

Example:

Locate list filtering and propose a plan. After confirmation, fix only the empty-result state, preserve styling, and report actual checks.

Inspect diffs and runtime behavior; cloud tasks also require a clear branch and artifact retrieval path.

Costs: software, models, and execution

International monthly prices checked 2026-10-25 are Free, Pro $20, Pro+ $60, and Ultra $200, with different usage and concurrency. Pricing

Regional pricing can differ. Open-source Agent APIs and commercial client subscriptions are separate.

Configuration and extensions

The website offers TraeCode for development and TraeWork for everyday work, with a separate TraeWork web entry. Choose the product for your task, then check regional account access and entitlements.

The open Agent uses YAML for models, tools, and step limits, records trajectories, and supports multiple providers. Prefer current README commands over old model examples.

Permissions, data, and limitations

Commands, edits, and browser tasks act on real environments. Check workspace, approvals, and login state; generation success is not test success.

Commercial and open-source surfaces have different features, accounts, and permission mechanisms. Documentation for one does not establish the behavior of another.

Frequently asked questions

Is trae-agent the entire desktop product’s source? No; it is a separate CLI agent project.

Does Free include every model? Check the current regional plan and UI.

Where should I start? Use the desktop/IDE for ordinary development and the open CLI for architecture research.
