Cursor
Cursor is a fork of VS Code, meaning it looks and feels almost identical to the editor millions of developers already use, but every layer has been rebuilt around AI. You can highlight a block of code and ask for an explanation, ask Cursor to implement a feature across multiple files, or trigger agent mode where it plans and executes a sequence of changes on your behalf.
It supports multiple underlying models, including Claude and GPT variants, and lets you switch between them depending on the task. Cursor's agent mode and background agents have made it the go-to tool for professional developers who want AI acceleration without giving up control over their codebase. Both Cursor and Claude Code support MCP server connections for extending agent capabilities.
At roughly $20 per month for the Pro tier, Cursor has become a standard line item in developer tooling budgets. It is best suited for developers who already know how to code and want AI to make them significantly faster. For non-technical founders building MVPs from scratch, tools like Lovable are typically a better starting point.
