Which one should you ship with? Here is the side-by-side panel verdict, pricing read, reviewer split, and community vote comparison.

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.

OpenAPI (formerly Swagger) is the standard for describing REST APIs. Swagger UI for documentation, codegen for clients/servers, and a massive ecosystem of tools.
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.”
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“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.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“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.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
