Cursor is an AI-first IDE built on VS Code that ships faster than any competitor. Agent mode (0.40+) handles multi-step engineering tasks autonomously — reading docs, writing tests, implementing features, and debugging. Background agents work independently on separate tasks while you focus elsewhere. Composer manages complex multi-file changes with a conversation interface. The most complete AI coding environment for developers who want power without leaving their familiar VS Code layout.

The Vercel AI SDK provides React hooks, streaming utilities, and provider abstractions for building AI-powered UIs. Works with any LLM provider. The standard for AI web apps.
Reviewer scorecard
“Agent mode is the real leap. I describe a feature, Cursor researches the codebase, writes tests, implements, and debugs — I review while it works. Background agents mean I always have something to review rather than waiting on AI. Cursor Tab's sub-100ms completions are still the best autocomplete available.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Agent mode can go sideways on ambiguous specs — specificity matters. When you're precise, it's genuinely autonomous. When you're vague, cleanup takes longer than writing it yourself. The 0.40+ UX overhaul cleaned up real pain points, but the context window costs add up.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Background agents running parallel tasks is the future UX model for AI coding. Cursor shipped this before anyone else. The question isn't whether this becomes the standard — it's how long before every IDE catches up.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
