Cursor Free Alternative: Open Source AI Editor using VScode

Introduction

Cursor is a popular AI-powered IDE built on VS Code. It offers impressive code generation and file management capabilities through prompts, allowing for updates to entire classes or functions with ease. However, it's a closed-source application with a subscription model, raising concerns about cost, enterprise usage limitations, and data security due to its reliance on proprietary servers. This post explores a free, open-source alternative that leverages trusted APIs.

Finding an Open-Source Alternative

Initially, I explored the VS Code extension Claude Dev, which offered similar functionality but only worked reliably with Anthropic's "claude-3-5-sonnet" model. Other models failed to perform file operations.

Cline: A Powerful Alternative

Recently, Claude Dev underwent a significant update, resulting in version 2.0, renamed "Cline". This updated version supports various models and provides functionality comparable to Cursor. Let's explore how to set it up.

Setting up Cline: A Step-by-Step Guide
