What each tool does
Bolt is an AI builder that works in the browser. You describe a website, web app, prototype or slide deck, and coding agents handle the technical work and fix errors. You can start from a blank project, a Figma design, a GitHub repository or a team template, and Bolt chooses the AI model automatically.
Cline is an open-source coding agent for developers. It runs in VS Code and other editors, in the terminal through a CLI, as a desktop app for macOS and Windows, or inside your own products through its SDK. Plan and Act modes let you review the approach before any change is made, it supports MCP integration, and you choose which models it uses. Cline reports more than 11 million installs.
Key differences
- Audience: Bolt is aimed at founders and non-coders; Cline assumes you are comfortable with code and a development setup.
- Openness: Cline is open source and lets you pick models; Bolt selects models for you.
- Workflow: Bolt builds a whole app from a chat; Cline works inside your existing codebase with a plan-then-act process.
- Setup: Bolt needs only a browser; Cline is installed into an editor, terminal or desktop app.
- Extensibility: Cline offers an SDK and MCP support for custom workflows; Bolt keeps things simple.
Which should you choose?
Choose Bolt if you are a founder, student or freelancer who wants a working prototype quickly and does not want to manage code or tools.
Choose Cline if you are a developer who wants an agent you can inspect, configure and run in your own environment, with control over which models it connects to.
Both are freemium. With Cline, model usage may involve separate costs depending on which provider you connect, so check the pricing pages for current plans before committing, especially if you pay in USD by card.
Can you use both?
Yes. You could create a first version in Bolt, export or sync it to GitHub, and then continue developing it in your editor with Cline once the project needs more careful, code-level work.
