Cursor AI After 30 Days: Our Honest VS Code Review

After 30 full days in Cursor, the AI-first code editor beats VS Code for most developers — but only if you write code for a living. We ditched GitHub Copilot, imported every extension, and lived inside Cursor for a month. What follows is an unfiltered, developer-focused review of what actually moved the needle, where the editor still falls short, and who should (and should not) switch.

The Features That Actually Changed Our Workflow

Cursor is not a sidebar wrapper bolted onto VS Code. It reads your codebase the way a senior engineer would — context-aware, multi-file, and fast enough to feel invisible.

Tab Auto-Complete That Predicts Edits, Not Just Lines

GitHub Copilot guesses your next line. Cursor Copilot++ (their custom autocomplete engine) predicts your next edit. Change a variable name inside a function and Copilot++ does not wait for you to reach the dependent calls — it jumps ahead and updates them before you scroll down.

Composer (Ctrl+I / Cmd+I)

This is where Cursor leaves standard editors behind. Hit Cmd+I, describe the change you want, and Composer edits multiple files at once. Add a new API route, update the database schema, and tweak the matching frontend components — all in a single prompt. The AI generates the files and applies edits across the codebase without manual file-hopping.

Codebase Indexing with the @ Symbol

Tag specific files, folders, or even live documentation sites using @. Struggling with a quirky third-party API? Type @https://api.docs.com and Cursor pulls the live docs, then writes accurate implementation code on the spot.

Where Cursor Saved Us Hours (Real Use Cases)

We tested Cursor on a messy Next.js and TypeScript project. These three workflows genuinely changed how we worked:

Refactoring Legacy Code — We highlighted an old, bloated Express.js middleware function, hit Cmd+K, and asked Cursor to refactor for performance and type safety. It removed nested promises and added clean Zod schemas in under ten seconds.
Onboarding to a New Codebase — Joining a new project is always painful. We indexed the entire repo and asked, "How does the authentication flow work here?" Cursor broke down exact file paths, session-state handling, and redirect logic.
Writing Unit Tests — We tagged our database utility file, typed @test into the prompt, and let Cursor generate a full Jest suite. It mocked the database calls correctly on the first try.

The Flaws: Where Cursor Still Frustrates

Cursor is not perfect. Here are the real friction points we hit after a full month.

It is a resource hog. Cursor indexes your files locally to feed them to the models. On massive monorepos this makes laptop fans scream. If your project contains half a million lines of code, expect noticeable lag.

The UI gets cluttered fast. Between the standard VS Code sidebar, the Cursor Chat panel, the Composer overlay, and inline edit boxes, screen real estate disappears quickly. It took us nearly a week to customize the layout into something tolerable.

Rate limits break your flow. Even on the $20/month Pro tier, "fast" queries are capped. Once you burn through them you fall back to slower queues — and that stall kills momentum during a heavy coding session.

Should You Switch From VS Code?

If you write code for eight hours a day, yes. Cursor is built on VS Code, so extensions, keybinds, and themes import with a single click. There is zero learning curve for the editor itself — only for the AI features, and those pay off fast.

If you only write a few lines of CSS a week, stick with VS Code and the free tier of Copilot. Cursor's value scales with how much code you write and how often you refactor it.

Cursor will not write your entire app for you, and it still hallucinates occasionally. But for navigating unfamiliar repos, handling tedious refactors, and generating boilerplate, it makes standard VS Code feel genuinely outdated.
