Cursor Reviews

Cursor vs Windsurf vs GitHub Copilot
The gap between Cursor and Windsurf is narrow and closing fast. While Cursor wins for now based on slightly better overall results and stability, Windsurf's rapid development and polished experience make it a compelling alternative that could easily take the lead with a few refinements. If you want to really push the boundaries of what AI can do for your coding, Cursor is...

Cursor vs GitHub Copilot
Cursor's tab completion is pretty wild. It'll suggest multiple lines of code, and it's looking at your whole project to make those suggestions. For TypeScript and Python files - when Tab suggests an unimported symbol, Cursor will auto-import it to your current file. Plus, it even tries to guess where you're going to edit next.

  • Asana cleared 5 years of engineering work in 2 weeks with Codex
    Since when? https://learn.chatgpt.com/docs/codex/cli https://github.com/openai/codex Looks like it's still a more-or-less-open-source product called Codex CLI. FWIW, there have been issues with various versions of ChatGPT not knowing what Codex is -- at least in the (IIRC) GPT-5.3 timeframe, there were serious issues with the knowledge cutoff. - Source: Hacker News / 15 days ago

  • As SpaceX deal looms, Cursor partners with Chainguard to secure open-source dependencies in AI-built code

  • How to Get Your First Tool Online
    The step up from there is an editor with a built-in agent like Cursor, Google Antigravity, Windsurf, or VS Code with a coding extension. These are code editors with an AI agent living inside them, and the difference is the responsible party for getting things from place to place.

  • I almost credited llms.txt for a Google AI Mode win. Then I read what Google actually says.
    Where llms.txt genuinely gets read is a different layer: coding and agent tooling — Cursor, Claude Code, GitHub Copilot, Windsurf — pulling a documentation site's pages with less token waste, plus emerging agent protocols like OpenAI's Agents SDK. That's real, and it's growing fast. - Source: dev.to / 2 months ago

    If you don’t believe me, go to Google AI Studio, get you an API key, create a project, then open Cursor, add the key, add whatever model they have available to use, run a task and you will see how models like Gemini 3.5 or 2.5 Flash which gives you 5 Requests Per Minute and 20 Requests Per Day will scream at you with hitting a limit rate. - Source: dev.to / 3 months ago
