Bolt.new vs Trae
Pricing
Bolt.new: Free tier, Pro from $20/mo
Trae: Free tier, Pro from $20/mo
Description
Bolt.new: Build full-stack web apps in your browser by describing what you want, no local setup needed
Trae: AI IDE from ByteDance with a limited free plan and paid plans from $20/mo, but read the privacy fine print
Pros
- Zero setup: open a browser tab and start building
- Live preview updates as the AI writes code
- Supports React, Next.js, Astro, and more out of the box
- 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
- Free tier token limits mean you hit walls mid-project
- Browser-based means no access to native tools, local databases, or heavy computation
- Generated code can be messy and hard to maintain long-term
- 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
Bolt.new runs a full Node.js environment inside your browser using WebContainers. You describe what you want to build, it writes the code, and you see a live preview instantly. No installing Node, no terminal, no VS Code, just a browser tab.
This is genuinely useful for prototyping. You can go from “I need a landing page with a waitlist form” to a working app in minutes. But the limitations show up when you try to build something complex: the free tier token limits are tight, and the generated code sometimes needs cleanup before it is production-ready. Think of it as a rapid prototyping tool, not a replacement for a real development setup.
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.
