Claude Code vs Cursor 3: which one actually ships your code faster?

Cursor 3 just dropped. The HN thread is 300+ comments. Developers are picking sides.

I've been running both in production for months. Here's the honest comparison — not marketing copy, not benchmarks, actual workflow differences.

The fundamental difference

Cursor 3: Editor-first. You stay in VS Code, the AI assists you.

Claude Code: Terminal-first. The AI runs your code, reads errors, iterates.

This sounds subtle. It's not. It changes how you think about your workflow.

What Cursor 3 does well

• Inline edits feel natural if you're already in VS Code
• Tab completion is fast and context-aware
• The new VS Code integration in Cursor 3 is genuinely better
• Great for surgical edits: "fix this function"

What Claude Code does well

• Full agentic loops: write → run → read error → fix → repeat
• It actually runs your tests and reads the output
• Can bash through a multi-file refactor without you babysitting it
• --print mode for non-interactive pipelines

The rate limit problem

Both tools hit limits. Here's how they differ:

Cursor 3: you hit the Fast Request limit, you get slow mode or pay more.

Claude Code: you hit Anthropic's rate limit, you get overloaded mid-task and your agent loop stops.

The fix for Claude Code is documented but not obvious:

export ANTHROPIC_BASE_URL=https://simplylouie.com/api

This routes your Claude Code through a proxy that handles rate limit distribution. The session continues. Your agent loop doesn't break.

Cursor 3 doesn't have an equivalent because it manages the API connection itself.

Practical comparison table

The Kimi K2.5 issue

Cursor recently used Kimi K2.5 (a Chinese AI model) without disclosure. This matters if you care about:

• Which model is actually processing your code
• Data residency
• Consistency of outputs

Claude Code is always Claude. ANTHROPIC_BASE_URL points to whatever proxy you configure, but the model you call is the model you get.

Workflow patterns

Cursor 3 is better for:

Open file → spot bug → cursor fixes it inline → commit

Fast, low-overhead, stays in your editor.

Claude Code is better for:

claude "add pagination to the users API, run the tests, fix any failures"

You describe the outcome. It does the work including running things.

The real question

Are you primarily editing or primarily building?

• Editing → Cursor 3
• Building → Claude Code

Many developers end up using both: Cursor for quick fixes, Claude Code for feature work.

Cost breakdown

Cursor 3: $20/month flat for Pro, $40/month for Business.

Claude Code: You pay per token at Anthropic rates. Heavy usage can run $50-150/month. The ANTHROPIC_BASE_URL proxy option at simplylouie.com runs ✌️2/month — that's $2, not a typo. It's built for developers who hit rate limits but don't want the per-token anxiety.

Bottom line

Cursor 3 is a better editor integration. Claude Code is a better autonomous agent.

The market is splitting: developers who want AI-assisted editing (Cursor) vs developers who want AI-driven execution (Claude Code). These are different use cases, not direct competitors.

What's your primary workflow? Drop it in the comments — I'm curious how the split looks in practice.
