Claude Code vs Cline: Anthropic's agent or the open-source alternative?

Choose Claude Code if you want Anthropic's own agent with Claude usage included in a flat monthly plan, plus a desktop app and a web version for people who don't use a code editor. Choose Cline if you want an open-source agent that runs in your editor or terminal, works with almost any model provider, and charges nothing for the tool itself, so you pay only for the AI you use. Both read a whole website project, edit files and run commands with your approval, so the choice comes down to models, billing and who will run it.

You can also combine them: Cline can use Claude through your own Anthropic API key, or, per its docs, through the Claude Code CLI on your Claude subscription. That second path has terms worth reading first.

Everything here is as of October 2026, from each vendor's own pages.

What each tool is

Claude Code is Anthropic's agentic coding tool. Anthropic says it "reads your codebase, edits files, runs commands, and integrates with your development tools," on the terminal, IDE extensions, a desktop app and the web.

Cline, made by Cline Bot Inc., describes itself as "an AI coding agent that lives in your editor and your terminal. It can read and write files, run terminal commands, use a browser, and help you build features through natural conversation." It comes as a VS Code extension, a JetBrains plugin, a CLI (npm i -g cline), a desktop app, an SDK, and Kanban, a board for running agents in parallel. Through the Agent Client Protocol (ACP) it also works in editors such as Cursor, Antigravity, Zed and Neovim.

The practical difference: Cline is a model-neutral harness you plug your own AI into. Claude Code puts the subscription, models and agent with one vendor. It also runs as an extension inside VS Code; our guide to Claude Code in VS Code covers that setup.

Side-by-side comparison

What you pay

Cline

Cline's pricing page says: "Cline is free for individual developers. Pay only for AI inference on a usage basis - no subscriptions, no vendor lock-in." There are three ways to pay for the AI:

• Bring your own key. "You can bring your own API keys from providers like OpenAI, Anthropic, Google, and others." With an Anthropic key, you pay Anthropic's per-token API prices directly.
• Cline usage billing. Pay-as-you-go credits through Cline, with some free models to try.
• ClinePass. A "Flat $9.99/month subscription that offers 2-5x the usage on popular open coding models compared to standard API rate." Its model list covers open-weight models only, not Claude.

Enterprise is priced on request and adds SSO, role-based access control, centralized billing, limits on inference providers and audit logs.

Claude Code

Claude Code comes with Claude Pro ($20 per month billed monthly, or $17 per month billed annually as $200 up front), Max (from $100 per month for 5x or 20x Pro's usage), every Team seat (Standard $25 per month billed monthly, $20 annually) and Enterprise (US$20 per seat per month billed annually, 20-seat minimum, plus usage at API rates). Usage on Pro, Max and Team draws from limits that reset every five hours and weekly. See our guide to Claude Code pricing.

What this means

Cline's model can cost the least when you use low-cost models or work occasionally, because you pay only for tokens. For heavy daily Claude work, per-token API billing can cost more than a flat plan, which also caps your bill. Price one real task both ways.

Using your Claude subscription inside Cline

Cline's Anthropic setup page offers two paths: an Anthropic API key, or "Claude Code (subscription-based)," which says it lets you "Use your Claude Max/Pro subscription through the Claude CLI." You install and sign in to Claude Code yourself, then point Cline at the claude command. Cline's own notes say this "Uses your Claude subscription limits instead of API token billing," that responses "may not stream token-by-token," and that "Image uploads and prompt caching are limited in this mode."

Before you rely on it, read Anthropic's legal and compliance page, which covers how Claude credentials may be used. About signing in with a Claude account (OAuth), it says: "OAuth authentication is intended exclusively for purchasers of Claude Free, Pro, Max, Team, and Enterprise subscription plans and is designed to support ordinary use of Claude Code and other native Anthropic applications." It also says: "Anthropic does not permit third-party developers to offer Claude.ai login into their own applications, or to route requests through Free, Pro, or Max plan credentials on behalf of their users." And it says this does not "prevent an end user from signing in to the unmodified Claude Code binary with their own Claude subscription." Finally: "Anthropic reserves the right to take measures to enforce these restrictions and may do so without prior notice."

The page doesn't name Cline or any other tool. For "questions about permitted authentication methods for your use case," it says to contact Anthropic's sales team. Read the current page, and ask Anthropic if you are unsure, before running a team's daily work this way. This is not legal advice.

Approvals, auto-approve and safety

Cline's default is cautious: "Every action requires your explicit approval." You can loosen that with auto-approve settings for specific kinds of action. Cline also has a YOLO mode that "auto-approves everything: file changes, terminal commands, browser actions, MCP tools, and mode transitions," and its own docs warn: "This is dangerous. YOLO mode disables all safety checks."

Claude Code has permission modes from manual approval to auto mode, where a separate classifier reviews actions, plus a bypass mode Anthropic says is for "Isolated containers and VMs only." From version 2.1.283, interactive terminal and VS Code sessions start in auto mode, and deny rules block actions in every mode. Our guide to permission modes explains which to pick.

The advice is the same for both tools: on a real website, never turn off approvals entirely. Keep the agent on a branch in git, and have a person review the diff before anything deploys. Our guide to using Claude Code safely on a live website goes deeper.

Cloud agents compared

Cline Cloud Agents run in a browser with "no IDE, CLI, or app to install." "Each task works on its own cline/ branch in your repository, and never commits directly to your default branch." You can run "up to 10 Cloud Agent sessions running at once and start up to 50 new sessions per day." Two limits matter: cloud agents use only Cline's own model options (ClineFree, ClinePass and Cline usage billing), and "Rules, skills, MCP servers, and connectors are not loaded in cloud sessions" yet.

Claude Code's cloud sessions run at claude.ai/code and in the Claude mobile app, on Anthropic-managed machines, and they "share rate limits with all other Claude and Claude Code usage within your account." They clone your GitHub repository, so a CLAUDE.md committed there comes with them. Our guide to Claude Code on the web has more.

Data and privacy

Cline's enterprise docs say "Prompts and code context go to the model provider you configure," that Cline "doesn't index or embed the contents of your repositories," and that its telemetry "doesn't include your code, file contents or prompts, except for requests to the Cline and ClinePass providers." Its privacy notice (last updated September 24, 2025) says that if you use your own API keys, "you provide this information directly to the third-party provider, and we do not collect it," and that "Some AI model providers may use content for training unless you have explicitly opted out." With Cline, your data terms are mostly your model provider's.

For Claude Code, Anthropic trains on Free, Pro and Max data only when the model-training setting is on, and you can turn it off. Under commercial terms (Team, Enterprise and the API), Anthropic "does not train generative models using code or prompts sent to Claude Code" unless the customer opts in. An Anthropic API key used in Cline falls under Anthropic's Commercial Terms. If your site holds client or regulated data, review the terms with your own advisers; this is not legal advice.

Where each fits website work

Claude Code suits you if:

• You want Claude on a predictable monthly plan rather than per-token bills.
• Non-developers on your team need to review changes in the desktop app, without a terminal or code editor.
• You want one vendor for the agent, the models and support.

Cline suits you if:

• You want an open-source agent you can inspect, extend or build on with its SDK.
• You want to mix models, including cheap open-weight models for routine edits and Claude for harder work.
• You want several model vendors billed through existing cloud contracts such as Bedrock, Vertex or Azure OpenAI. (Claude Code also runs through Bedrock, Google Cloud and Microsoft Foundry, with Claude models only.)

Running agents in parallel needs care whichever tool you use. When we rebuilt eseospace.com (see our rebuild case study), one session regenerated pages that another had just edited, and those edits disappeared. The fix: check git history for changes you didn't make before any deploy. For another comparison, see Claude Code vs Kiro.

How to decide

1. Decide on models. Claude only, on a flat plan, points to Claude Code. A mix of providers points to Cline.
2. Check the terms for your setup, especially if you plan to run a Claude subscription through another tool.
3. Pilot on a copy of the site, in git, with one real task and approvals on.
4. Write down the rules: what the agent may touch, who reviews, who deploys.

Conclusion

Claude Code and Cline are both serious agents for website work. Claude Code is Anthropic's integrated package, with Claude usage in a flat plan and surfaces for non-developers. Cline is a free, open-source harness that works with nearly any model, so your costs and data terms follow the provider you pick. Choose by models, billing and who will use it, test it on a copy of your site, and keep a person reviewing every change. If you want help choosing tools and setting up a safe review process for your team, our Claude Code consulting covers that. More guides are in our Claude Code Guide.
