Claude Code setup
Set ANTHROPIC_BASE_URL to https://api.runapi.ai and use your RunAPI key as the API key. Claude Code runs unmodified.

Claude Code vs Cursor
Claude Code is a terminal agent from Anthropic. Cursor is an AI-powered fork of VS Code. They solve different problems — Claude Code builds the feature, Cursor helps you review and polish it — and both can run on a single RunAPI key at 50% off token rates with no shared quota pool.

RunAPI Editorial
At a glance
What is the difference between Claude Code and Cursor?
Claude Code runs in your terminal and handles the whole agent loop — it reads files, plans changes, runs commands, and ships the result. Cursor is a full IDE with tab completion, Cmd+K inline edits, and an agent mode. Neither is strictly better. If you live in the terminal and want to hand off large tasks, Claude Code. If you want to stay in your editor and review every diff, Cursor.
Claude Code
Terminal agent by Anthropic. Plans, edits files, and runs commands in one loop. Strongest for large refactors and headless automation — it outperforms Cursor at rewriting big files despite having only one input mode.
Cursor
AI IDE forked from VS Code. Three input modes: tab completion, Cmd+K for inline edits, and agent mode. Model buffet includes Claude, GPT, and Gemini — switchable per request.
Shared need
Both consume model tokens and both sell subscriptions. Cursor Pro is $20/mo; Claude Max is $100/mo. Hidden costs add up fast — background agents, BugBot, and thinking mode all cost extra on top.
RunAPI angle
Point either tool at RunAPI to pay per token at 50% of official rates. No subscription, no per-seat fee, and your coding quota doesn't drain when you're using claude.ai chat on the side.
Side by side
How do Claude Code and Cursor compare feature by feature?
The table maps each tool against the dimensions developers ask about most: interface, model access, context handling, and extensibility.
| Dimension | Claude Code | Cursor |
|---|---|---|
| Interface | Terminal CLI | Desktop IDE (VS Code fork) |
| Primary mode | Agentic — plans, edits, runs commands | Tab completion + Cmd+K + agent mode |
| Model | Claude models only (Anthropic-hosted) | Claude, GPT, Gemini — switchable per request |
| Context window | Up to 200K tokens (1M on select models) | Depends on selected model |
| Custom API key | ANTHROPIC_BASE_URL override | OpenAI-compatible base URL override |
| Best for | Automation, CI, headless tasks, large refactors | Interactive editing, inline completions, diff review |
Plans and costs
How much do Claude Code and Cursor cost?
Both tools sell subscriptions, but both also accept a custom API key so you pay only for the tokens you use. Watch out for hidden costs — Cursor's background agents, BugBot, and thinking mode are billed on top of the base plan. The table shows official plans next to the RunAPI metered alternative.
| Plan | Price | What you get | RunAPI alternative |
|---|---|---|---|
| Cursor Pro | $20/mo | Fast premium requests, agent mode | Bring a RunAPI key, pay per token |
| Cursor Business | $40/user/mo | Team admin, privacy mode, SSO | Per-token billing, no per-seat fee |
| Claude Pro | $20/mo | Claude Code with usage caps | Metered API, no caps |
| Claude Max | $100/mo | Higher Claude Code limits | $100 buys ~6.7M Sonnet 4.6 output tokens |
One key, both tools
How does RunAPI work with Claude Code and Cursor?
Both tools accept a custom base URL. Point Claude Code at RunAPI with ANTHROPIC_BASE_URL, or set Cursor's OpenAI base URL to RunAPI — same key, same balance, 50% off official token rates.
Cursor setup
In Cursor settings, set the OpenAI base URL to https://api.runapi.ai/v1 and paste your RunAPI key. Select any Claude or GPT model ID.
No subscription lock-in
Pay per token instead of $20–$100/mo. If you use both tools, one balance covers both — no double subscription, no shared quota pool between your chat and your coding sessions.
Multi-model access
Switch between Claude, GPT, and Gemini without being locked into one IDE. Unlike Cursor's built-in model buffet, RunAPI works from any tool that accepts a base URL override.

Frequently asked questions
Claude Code vs Cursor FAQ
If you're a better programmer, is Cursor the better choice?
The better you are at code, the better Cursor is for you. Cursor's tab completion and diff review let experienced developers stay in control of every line. Claude Code suits developers who want to hand off bigger tasks and trust the model to figure out the steps — it builds the house while Cursor paints the walls.
Can I use Claude Code and Cursor together?
Yes. Many developers run Cursor for interactive editing and inline completions, and Claude Code for terminal automation and headless tasks. They cover different parts of the workflow. A single RunAPI key powers both tools from one balance, so you're not paying two separate monthly subscriptions.
Aren't you worried you'll lose track of your codebase if you let AI code without reviewing?
It's a real concern. Claude Code runs fast in agent mode and it's easy to end up with code you didn't fully review. If you want to stay on top of what's in your codebase, Cursor's diff view makes it easier to approve or reject each change before it lands. Claude Code's plan mode (Shift+Tab twice) lets you preview the plan before it runs.
How much does each tool actually cost?
Cursor Pro is $20/month. Claude Pro is $20/month; Claude Max is $100/month for higher Claude Code limits. Both tools also accept a custom API key, so you pay per token instead. With RunAPI that's 50% off official rates. That's usually cheaper when your usage is light or bursty — and unlike subscriptions, your coding quota doesn't share a pool with your claude.ai chat sessions.
Which tool has a bigger context window?
It depends on the model, not the tool. Both can use Claude models with up to 200K tokens, and select models reach 1M. The window is set by which model ID you choose — identical across Claude Code and Cursor when routing through the same model.
Can I switch from a subscription to API billing?
Yes. Both tools accept a custom base URL and API key in settings. Point them at RunAPI and you switch from a fixed monthly fee to pay-per-token billing without reinstalling anything. Your projects, configs, and cursor rules or CLAUDE.md files stay exactly as they are.
Do I need two API keys for two tools?
No. One RunAPI key works in both Claude Code and Cursor. RunAPI exposes both an Anthropic-compatible endpoint and an OpenAI-compatible endpoint, so the same key and the same balance serve either tool. You manage one account, top up one balance, and see all usage from both tools in a single dashboard.
