About Trae

Trae is ByteDance’s free AI code editor that punches well above its price tag. Free plan ships 5,000 autocompletions/month + access to premium models (Claude 4, GPT-4o, DeepSeek R1, Gemini 2.5 Pro). Builder Mode is an autonomous agent that generates directory structure, code, terminal commands, and iterates on errors. SOLO (2.0) acts as a ‘context engineer’ running requirements analysis, code generation, terminal commands, browser testing, and deployment from a natural-language description. Token-based pricing as of Feb 2026: Lite $3/mo, Pro $10/mo, Ultra $100/mo. macOS, Windows, and browser-based Cloud IDE.
