About Cline
Cline is an open source AI coding agent that operates across multiple interfaces: as a CLI tool, desktop application, VS Code extension, JetBrains plugin, and SDK. It lives in the developer tooling ecosystem and is built with TypeScript under the Apache 2.0 license. The project solves the problem of fragmented AI assisted coding workflows by unifying agent capabilities—code generation, command execution, project wide edits, and human in the loop approval—into a single extensible engine that works consistently across environments.
