Product overview
Cline offers an autonomous AI coding assistant that integrates into code editors like VS Code, Cursor, and JetBrains, enabling developers to read/write files, run terminal commands, use browsers, and build features via natural language with user approval for every action. It is used by over 5 million individual developers and enterprises like Samsung, SAP, and Salesforce for complex coding tasks, codebase analysis, debugging, and automation. What distinguishes Cline is its open-source nature, zero-trust client-side architecture, support for any AI model/provider without lock-in, and full cost transparency where users pay AI providers directly.,
Revenue model
Free open-source core for individuals (pay AI providers directly for inference usage or BYOK); enterprise contracts for teams with features like SSO, centralized billing, audit logs, and dedicated support (pricing not publicly listed).
