TRAE offers TRAE IDE for AI-assisted software development and TRAE Work as an AI work assistant for professionals. TRAE IDE combines IDE mode with SOLO, an autonomous coding agent for end-to-end tasks. Users can create custom agents, have them act as sub-agents, and connect them to external resources through Model Context Protocol integrations. TRAE SOLO integrates with Vercel for deployment and Vercel AI Gateway model access; TRAE IDE and SOLO also integrate with Supabase services and Supabase MCP. The Free plan lists 5,000 autocomplete requests per month and two concurrent cloud tasks. A 14-day Pro trial is for new users who add a payment method within 48 hours after sign-up. TRAE says codebase files are stored locally, although files may be temporarily uploaded for embedding during indexing before plaintext is deleted. Enterprise states that code is encrypted in transit, not stored on its servers, and not used to train models; it is SOC 2 Type 2 certified. Enterprise repo indexing supports up to 100K files and 150M lines of code.
