Cline vs Trae
Pricing
Cline: Free (open source), you pay for the AI API you choose
Trae: Free tier, Pro from $20/mo
Description
Cline: Open-source VS Code extension that acts as an autonomous coding agent. Bring your own AI model
Trae: AI IDE from ByteDance with a limited free plan and paid plans from $20/mo, but read the privacy fine print
Pros
- Use any AI model (Claude, GPT-4, Gemini, local models): you control the cost
- Can browse the web, run terminal commands, create files, and edit code autonomously
- Free and open source: no subscription, just API costs
- Free plan includes 5,000 autocompletions a month and Auto mode
- SOLO mode for multi-step agent tasks, plus cloud tasks in TraeWork on paid plans
- VS Code-based so the interface is familiar
Cons
- API costs are on you and can surprise you if you are not watching
- Setup takes more work than commercial alternatives: API keys, model selection, configuration
- Quality depends entirely on which AI model you pick
- Made by ByteDance: security researchers reported in 2025 that it kept sending telemetry after users opted out
- Chats and code snippets may be used for model training unless you turn on Privacy Mode while logged in
- The free plan is limited to Auto mode: choosing models needs Pro at $20/mo
Details
Cline is a VS Code extension that turns your editor into an AI coding agent. Pick your AI model (Anthropic Claude, OpenAI, local models through Ollama), give it a task, and it will plan, write code, run commands, and iterate. It asks for permission before each action, so you stay in control.
The big advantage over Cursor is flexibility and transparency. You see exactly what you are paying (API costs per request), you can switch models anytime, and there is no subscription. The big disadvantage is that you have to manage all of that yourself. If you want something that just works out of the box, Cursor is easier. If you want to pick your own model and only pay for what you use, Cline is the way.
Trae is an AI IDE from ByteDance. The editor is VS Code-based, and SOLO mode can plan and carry out multi-step coding tasks. The free plan gives you Auto mode, limited usage and 5,000 autocompletions a month. Pro costs $20 a month with $20 of model usage included and unlimited autocomplete, Pro+ costs $60, and Ultra costs $200 with early access to new models.
The elephant in the room is ByteDance. In 2025 security researchers reported that Trae kept sending usage data to ByteDance servers even after users opted out of telemetry. Trae’s documentation says your codebase files are not used for training, but your chats, related code snippets and AI output may be used for analytics and model training unless you enable Privacy Mode, which only applies while you are logged in. If you are working on anything sensitive (client projects, proprietary code, anything with user data), this is a real concern. Cursor and Devin Desktop cost the same as Trae’s Pro plan.
