AI Coding Tools
Claude Code vs Cursor
Claude Code is a terminal-based coding agent. Cursor is a VS Code fork with AI built in. Both consume API tokens — RunAPI gives you one key, one balance, half the price for both.
Feature-by-feature comparison
| 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 |
| Models | Claude only | Claude, GPT, Gemini (switchable) |
| Context | Up to 200K tokens (1M on select models) | Depends on selected model |
| Custom API key | ANTHROPIC_BASE_URL override | OpenAI-compatible base URL |
| Best for | Automation, CI, large refactors | Interactive editing, inline completions |
How much do they cost?
| 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 rolling caps |
| Claude Max | $100/mo | Higher Claude Code limits | ~6.7M Sonnet output tokens |

API Key: $RUNAPI_API_KEYClaude Code vs Cursor FAQ
Claude Code suits people who already work in a terminal and want an agent to plan and execute multi-file changes. Cursor suits people who want completions and inline diffs while they type. Neither replaces the other, and many developers run both.
Yes. Edit interactively in Cursor and hand long refactors or CI tasks to Claude Code. With a RunAPI key both draw from one balance, so you see combined spend in one dashboard.
Commit before handing work to an agent and review the diff after. Claude Code writes changes to the working tree; Cursor shows inline diffs you accept or reject per hunk.
A typical day of agentic coding on Sonnet runs $1.50–$6 in tokens through RunAPI. Heavy multi-agent workloads on Opus can reach $20/day; light usage stays under $1.
Claude Code inherits Claude's window — 200K tokens, up to 1M on select models. Cursor's window depends on the model you pick, so the ceiling is the same when you point it at the same model.
Yes, and you can run both while you compare. Set the base URL in either tool and the subscription simply stops being the path requests take.
No. One RunAPI key works in Claude Code and Cursor at once, and you can scope separate keys per tool if you want spend split in reporting.
