Cursor is a fork of VS Code rebuilt around an agent instead of a chat bolted onto an editor. Tab completion, inline edits and the Composer agent cover the whole interactive loop - the work where you steer every change and review every diff.

Where it shines

• The review flow. Composer proposes multi-file changes as diffs you accept piece by piece - the fastest human-in-the-loop iteration available.
• Tab that thinks ahead. Completions predict the next edit across lines, not just tokens; it removes real friction once it learns your rhythm.
• One interface for everything. Editing, chatting and agent runs live in the same window, so context-switching cost is zero.

Where it falls short

• It is a VS Code fork: JetBrains users must migrate their whole setup to use it.
• Fully autonomous, hands-off tasks are not its home turf - for long delegation you want a terminal agent, and Cursor will feel like micromanaging.
• Heavy agent usage burns through included credits; power users hit caps before month-end.

The real cost

The free tier is enough to learn the loop. Serious daily use needs the paid plan, and if you lean on the agent hard, expect to watch usage meters or bring your own model keys for heavy weeks. Budget for the plan, not just the sticker.

Verdict

The default choice when your day is editing, reviewing and shipping from one screen. Pair it with a terminal agent for delegated work instead of forcing it to be something it isn’t.
