Cline is an autonomous coding agent plugin for VS Code, considered the best open-source alternative to Cursor.The plugin was tested on a project involving dockerizing a Retrieval-Augmented Generation (RAG) system using FastAPI on Google Cloud.Initial attempts with local models like Gemma 2 and Qwen 2.5-coder were unsuccessful due to system resource constraints.Cline, when used with Claude 3.7, showed significant improvements in terms of efficiency and performance.While Claude proved effective, its usage incurred costs, making Cline an expensive option for regular development tasks.Local models like Gemma 2 and Qwen 2.5 Coder struggled with generating outputs and coping with system limitations.Cline's functionality with Claude 3.7 included autonomously generating Dockerfiles, docker-compose.yml, and FastAPI app code.Running the Dockerized app created by Cline was successful and seamless, showcasing its capability to handle the setup efficiently.Despite its power, Cline's high cost and reliance on external models like Claude raise practicality concerns for routine development.In comparison to Cursor, Cline with Claude excelled in performance but may not be as cost-effective for everyday development tasks.Cline offers a powerful tool for AI-powered development, but its pricing and reliance on external models may limit its practicality.
