Claude Code vs Cursor - Plus the Third Option (cto CLI)

Claude Code is Anthropic's first-party coding agent (CLI + IDE extensions + desktop + web + iOS). Cursor is the IDE-first product with a CLI extension. They're the two most-mentioned coding tools of 2026 but they shape different work - terminal-first agentic versus editor-first AI. This page covers when each wins, what they actually cost, and where cto CLI fits as the free-forever multi-model third option.

TL;DR. Editor-first work → Cursor. Terminal-first / CI / mobile-continuation → Claude Code. Free + multi-model with Auto routing → cto CLI. All three are valid; the answer depends on where your work actually happens.

The three corners, briefly

When Claude Code wins

Claude Code's strength is the agent loop - long-running tasks spanning many files, running commands, verifying results. The CLI is composable (tail logs | claude -p "..."); the agent SDK lets you build custom workflows; the multi-surface design moves a session from terminal to mobile.

Pick Claude Code if:

• Daily work happens in the terminal more than the editor.
• You run long agentic builds (30+ minutes).
• You're committed to Claude and want the best Claude-native UX.
• You need multi-surface continuity (start desktop, finish mobile).
• You run agents in GitHub Actions / GitLab CI.

When Cursor wins

Cursor's strength is the editor experience. Tab completions, inline edits with diff review, fast model switching from a frontier menu - all inside the IDE.

Pick Cursor if:

• Daily work happens in the editor, not the terminal.
• You're a heavy user of tab completions + inline refactors.
• Visual diff review is core to how you accept AI changes.
• You want to switch between Composer 2.5 and frontier models without leaving the IDE.

When cto CLI wins

cto CLI is the free-forever third option. Ships as an opencode plugin + provider - opencode runs in your terminal; the cto.new gateway handles LLM calls so you don't bring API keys. Pick from 10+ frontier models via opencode's /model slash command.

Pick cto CLI if:

• Cost is the binding constraint. Both Claude Code and Cursor are $20/month+; cto CLI is free forever, ad-supported.
• You want multi-model without managing API keys. cto's gateway handles auth; you don't bring keys.
• You want every frontier model in one CLI without bringing keys.
• You don't want to standardize on one editor. cto CLI is editor-agnostic.
• You want a managed gateway instead of bringing API keys.

Models - what each lets you reach

Claude Code (May 2026): Claude Opus 4.8, Sonnet 4.6, Haiku 4.5 native. Third-party providers on Terminal CLI and VS Code.

Cursor (May 2026): Anthropic (Opus, Sonnet), OpenAI (GPT-5.5 and family), Google (Gemini 3.1 Pro, Flash), Cursor (Composer 2.5), xAI (Grok 4.3).

cto CLI: Claude Opus 4.8, Sonnet 4.6, GPT-5.5, GPT-5.3 Codex, Gemini 3.5 Flash, Gemini 3.1 Pro, GLM 5.1, Grok 4.20, Kimi K2.6, MiniMax M2.7 - pick via opencode's /model slash command, no API keys required.

cto's GLM 5.1, Kimi K2.6, and MiniMax M2.7 are the broader open-frontier coverage you don't get on Claude Code or Cursor.

MCP - all three support it

Different config models:

• Claude Code - .claude/mcp.json (per project) or ~/.config/claude-code/mcp.json (user).
• Cursor - .cursor/config.json per project, or ~/.cursor/mcp.json global.
• cto CLI - opencode's native MCP config (stdio or streamable HTTP). Bring your own MCP servers; whatever opencode supports, cto CLI supports.

Functionally equivalent capability, different config UX. cto's account-wide model is more centralized; Claude Code and Cursor's per-project files are more portable.

Migration

From Claude Code → cto CLI: install with curl -fsSL https://cto.new/install | bash. Sign in (browser). Re-wire any MCP servers in opencode's standard MCP config.

From Cursor → cto CLI: same. Cursor's .cursorrules doesn't auto-port; opencode reads similar project rules conventions - point the agent at your project rules and it'll respect them.

Coexistence: all three install side-by-side. Many developers use Cursor (editor) + cto CLI (terminal/CI/free pilots) + Claude Code (only when on Anthropic specifically).

FAQ

Is Claude Code or Cursor more expensive?

Same starting price at $20/month per seat. Heavy usage diverges: Claude Code Max is $200/month (unmetered); Cursor Pro+ is $39/month with caps. Cursor's predictable monthly cost is friendlier for budgeting; Claude Code Max is friendlier for heavy users with the budget.

Can I use cto CLI alongside Claude Code or Cursor?

Yes. They don't conflict. Common stack in 2026 is Cursor editor + cto CLI for terminal/CI.

Which has the best models in 2026?

All three reach the frontier (Claude Opus 4.8, GPT-5.5, Gemini 3.1 Pro). cto CLI's gateway adds broader open-frontier coverage (GLM, Kimi, MiniMax). Cursor adds Composer 2.5 and Grok. Claude Code is Claude-first with third-party providers grafted on.

Is cto CLI really free forever?

Yes - ad-supported, rolling 24h + 7d limits. Premium raises the limits + unlocks premium models and agent features. No credit card to start.

Which has the best MCP support?

All three are functionally equivalent at the protocol level. Claude Code and Cursor use per-project / per-user config files. cto CLI inherits opencode's native MCP config UX - bring your own server configs in opencode's standard format.

Can Claude Code use non-Anthropic models?

Yes, on Terminal CLI and VS Code surfaces, via third-party providers. Still Claude-first in UX, and you bring keys for the third-party models. cto CLI's gateway is provider-neutral and handles auth for all the supported models.
