Cursor 3 Launches Agent-First Coding to Take on Claude Code and Codex

Cursor has launched Cursor 3, a radical new "agent-first" coding product that reimagines how developers interact with their codebase. Developed under the codename Glass, Cursor 3 lets developers manage multiple AI agents from a natural language prompt box instead of writing code directly — putting it in direct competition with Anthropic's Claude Code and OpenAI's Codex.
This is not a minor update. Cursor 3 represents a fundamental shift from a traditional IDE with AI assistance to a conversation-driven coding platform where AI agents do the heavy lifting.
How Cursor 3 Works
Instead of typing code in an editor, developers describe what they want in a natural language prompt box. Cursor 3 then spins up cloud-based AI agents that autonomously generate features, fix bugs, or refactor code. Developers review the results locally on their machines.
Key capabilities:
- Multiple concurrent agents — spin up several AI agents working on different tasks simultaneously
- Sidebar agent manager — monitor and manage all active agents from a single panel
- Cloud-based execution — agents run in the cloud, results sync to your local machine
- Integrated with existing IDE — Cursor 3 lives alongside the traditional code editor, not replacing it
- Code review workflow — review AI-generated code before committing, just like a PR review
Cursor 3 vs Claude Code vs Codex
| Feature | Cursor 3 | Claude Code | OpenAI Codex |
|---|---|---|---|
| Interface | Desktop app + agent panel | Terminal CLI | Cloud dashboard |
| Multi-agent | Yes, concurrent | Sequential | Yes, concurrent |
| Execution | Cloud + local sync | Local machine | Cloud sandboxed |
| AI Models | OpenAI, Claude, Gemini | Claude only | OpenAI only |
| Pricing | $20–$200/mo | ~$20/mo (Max plan) | $200/mo (Pro) |
Pricing
Cursor 3 is available across Cursor's existing plans:
- Pro — $20/month (extended agent requests, unlimited tab completions)
- Pro+ — $60/month (3x usage of OpenAI, Claude, and Gemini models)
- Ultra — $200/month (20x usage, priority access to new features)
The model-agnostic approach is Cursor 3's biggest advantage — you can use the best model for each task rather than being locked into a single provider.
The Bigger Picture
The agentic coding space is heating up fast. Claude Code proved that developers are ready to delegate coding tasks to AI agents. Codex showed that cloud-based agents could handle complex, multi-file changes. Now Cursor 3 is combining both approaches with a polished desktop interface.
The race is on to become the default way developers build software — and it is no longer about who has the best autocomplete. It is about who has the best agents.
Bottom Line
Cursor 3 is a smart move. By offering a desktop app with multi-model support, concurrent agents, and a familiar IDE alongside the new agent interface, Cursor is hedging its bets — giving developers a choice between traditional coding and agent-driven development. For developers who want the flexibility of choosing between Claude, GPT, and Gemini without switching tools, Cursor 3 is the most compelling option on the market right now.
