Claude Code vs Cline
Open-source AI coding agent for VS Code
Last reviewed 2026-05
Cline is one of the strongest open-source AI coding agents available. It runs inside VS Code, supports any OpenAI-compatible model, and gives you full transparency over what the agent does. Claude Code is Anthropic's first-party CLI agent, optimized for Claude models and terminal workflows, with deeper instrumentation hooks. The choice is mostly about whether you want vendor-anchored polish (Claude Code) or open multi-model flexibility (Cline).
At a glance
| Feature | Claude Code | Cline |
|---|---|---|
| Surface | Terminal CLI | VS Code extension |
| License | Closed (Anthropic) | Apache 2.0 |
| Model support | Claude only (Anthropic API) | Claude, GPT, Gemini, Ollama, OpenRouter, anything OpenAI-compatible |
| Pricing | Anthropic API costs or Pro/Max plan | Bring your own API key; extension is free |
| Stop hooks | Yes — native exit hooks | No |
| Skill ecosystem | Yes — installable skills | Workflows + MCP servers, no plugin marketplace |
| Token tracking | Native + pushes to vibecodestats.dev | In-UI counter only |
| Best for | Terminal-first power users | Multi-model experimenters, IDE-first devs |
When to pick Claude Code
- Workflows where the latest Claude features land first (extended thinking, prompt caching, new agent capabilities)
- Terminal-native development across multiple machines, ssh sessions, or tmux setups
- Instrumented deep work — pushing every session's stats to a leaderboard like vibecodestats.dev
- Anthropic Pro/Max plan users who don't want to manage API keys and per-model billing
When to pick Cline
- Running multiple model providers behind one UI — Claude for hard reasoning, Gemini for cheap context, local models offline
- Auditing the agent's every step in a visual diff inside the IDE
- Self-hosting the agent code or forking the behavior
- Cost-sensitive workflows using cheaper non-Claude models
Which is right for you?
Care most about agent autonomy + terminal feel + first-party Anthropic polish? → Claude Code. Care most about model flexibility, open source, or running local models? → Cline. Run both — many devs do.
FAQ
Is Cline a fork of Claude Code?
No. Cline is its own project, originally created by Saoud Rizwan and now developed by Cline Inc. It predates Claude Code's general availability and was built as an open-source alternative.
Can Cline use Claude models?
Yes. You add your Anthropic API key and Cline routes requests through Claude Sonnet, Opus, or Haiku. Many devs use Cline specifically to access Claude with full transparency.
Does Cline have something like vibecodestats.dev?
Not natively. You can track Cline usage by inspecting your Anthropic API dashboard, but the per-session leaderboard model that vibecodestats.dev provides is specific to Claude Code's stop-hook architecture.
Why pick Claude Code if Cline is free and open source?
Polish and pace. Anthropic ships Claude-Code-specific features first (skills, extended thinking, certain MCP behaviors). For most users, the time saved outweighs the cost of being inside the Anthropic ecosystem.
