Cline vs Cursor: open source agent or AI code editor?

What is the difference between Cline and Cursor?

Cline is an open source coding agent that plugs into the tools you already use; Cursor is an AI code editor you switch to. Cline runs as an extension in VS Code, Cursor, JetBrains IDEs and others, as a CLI, and as a desktop app, and it works with almost any model provider you connect. Cursor is a standalone editor with its own autocomplete, agent, CLI and cloud agents, paid for through Cursor plans.

So the choice is less about which agent is smarter and more about how you want to buy and run AI. If you want to bring your own model and keep your editor, Cline fits. If you want one product that bundles the editor, models and cloud features, Cursor fits. The two also work together, since Cline installs inside Cursor.

All facts below come from the official docs and pricing pages as of 24 October 2026.

How does Cline work?

Cline describes itself as "Your AI-powered agent for complex work." It reads and writes files, runs terminal commands and uses a browser, and the docs say "Every action requires your explicit approval." The Cline repository is licensed under Apache 2.0 and calls it "The open source coding agent in your IDE, terminal, & desktop!"

You can run it in several places (the Cline guide covers setup):

• IDE extension for VS Code, Cursor, Windsurf, VSCodium and Antigravity, plus a JetBrains plugin.
• CLI, installed with npm i -g cline, for interactive sessions or headless scripts.
• Desktop app for macOS and Windows (Windows in beta), aimed at open weight models.
• Cloud Agents in the browser, an SDK, and a Kanban board for running several agents.

The core loop is Plan and Act. In Plan mode, Cline "can read your codebase, run searches, and discuss strategy, but cannot modify any files or execute commands." You then switch to Act mode, and the conversation carries over. You can even set a different model for each mode, such as a stronger model for planning and a faster one for edits.

Cline also saves checkpoints after each tool use in a shadow Git repository, so you can roll back files without touching your real Git history. Auto Approve lets you choose which actions run without asking, such as reading project files or running safe commands.

For scripts and CI, the CLI has a headless mode:

npm i -g cline
cline auth                                   # pick a provider and model
cline "refactor this module to use async/await"
git diff | cline "review these changes"      # piped input runs headless
cline --json "list TODO comments"            # JSON output for scripts

How does Cursor work?

Cursor describes itself as "a coding agent for building ambitious software." It ships as a desktop editor, and Cursor's help center has guides for moving over from VS Code and JetBrains. Its main pieces:

• Tab, "Cursor's AI-powered autocomplete." It suggests code as you type based on recent edits, surrounding code and linter errors, and can jump you to the next place to edit.
• Agent, which "can complete complex coding tasks independently, run terminal commands, and edit code." It saves checkpoints so you can restore files.
• Cursor CLI, installed with curl https://cursor.com/install -fsS | bash, which runs the agent as agent, with Agent, Plan and Ask modes and an agent -p print mode for scripts.
• Cloud Agents, which run in isolated cloud VMs with your repos and dependencies.
• Bugbot for AI code review, on Premium and higher plans.

On models, Cursor's models page lists its own models (Composer 2.5, plus Grok models it describes as "Jointly trained by Cursor and SpaceXAI") and third-party models from Anthropic, OpenAI, Google and others. Third-party models are not included on Free or Plus; on Premium and above you use them "at API list price, paid from prepaid credit."

How do Cline and Cursor compare side by side?

How much do Cline and Cursor cost?

They charge for different things, which matters more than the headline numbers.

Cline (pricing) says: "The Cline open source extension is completely free for individual developers." You pay for model usage in one of three ways:

• Bring your own key from a cloud provider, or run local models through Ollama or LM Studio.
• Cline (usage-billing): sign in, add Cline credits and pay as you go, with limited-time free model promotions.
• ClinePass: $9.99 a month as of October 2026, which Cline says offers "2-5x the usage on popular open coding models compared to standard API rate." It covers open models such as GLM, Kimi, DeepSeek and Qwen.

Enterprise plans with SSO and centralized billing are priced on request.

Cursor (pricing), as of October 2026:

• Free: $0, with limited agent and chat requests.
• Plus: $8 a month. Only Grok models are available on this plan.
• Premium: $30 a month, 4x the usage of Plus, plus cloud agents, AI code review and third-party models billed at API list price.
• Super: $100 a month, 15x Plus usage.
• Ultra: $200 a month, 50x Plus usage.
• Teams: from $30 per user per month, with SSO and usage analytics; Enterprise is custom.

If you want Claude or GPT models specifically, note the split. In Cline you connect that provider directly and pay its rates. In Cursor you need Premium or higher and pay API list price from prepaid credit.

Can Cline and Cursor share rules and skills?

Yes, and this is where a little setup saves a lot of copying.

AGENTS.md is the shared file. Cline's rules docs list AGENTS.md as a supported rule type "for cross-tool compatibility." Cursor's rules docs call it a "Simple alternative to .cursor/rules." One AGENTS.md at the repo root reaches both.

Tool-specific rules stay separate. Cursor's project rules are .mdc files in .cursor/rules/ with description, globs and alwaysApply frontmatter (see the Cursor rules guide). Cline reads its own .clinerules/ folder, where a paths list in the frontmatter makes a rule conditional. Cline also auto-detects a .cursorrules file, but its docs do not mention .mdc rules.

Skills overlap well. Both follow the SKILL.md format with a name and a description. Cline's skills docs say the name "must exactly match the directory name" and the description has a "max 1024 characters." Cline loads project skills from .claude/skills/, among others, and its config docs add .agents/skills/. Cursor loads both of those too. Put a skill in .agents/skills/ and both tools pick it up.

Which should you pick?

Pick based on how you want to pay for models and whether you want to change editors.

Cline tends to fit when:

• You want to keep VS Code, JetBrains or your current editor and add an agent to it.
• You want to choose any provider, use your own API key, or run local models.
• You want an Apache 2.0 codebase you can audit, fork or build on with the SDK.
• You like an explicit Plan then Act flow with an approval on every action by default.

Cursor tends to fit when:

• You write a lot of code yourself and want Tab autocomplete with multi-line and cross-file edits.
• You want one subscription that covers the editor, agent, cloud agents and code review.
• You want to start agents in the cloud and pick them up later.
• Your team wants centralized billing, SSO and shared rules and skills through Cursor's team plan.

You can also use both. Install Cline in Cursor, keep shared instructions in AGENTS.md and shared skills in .agents/skills/, and use whichever agent suits the task. If you are also weighing a terminal agent, see Claude Code vs Cursor and Claude Code vs Cline.

Keep your prompts and skills portable

Agents come and go faster than the instructions you build up for them. Kipt keeps your prompts and Agent Skills as Markdown in a private GitHub repo you own, and installs every skill into Claude Code or Codex with one npx skills add command. If you have a prompt you keep pasting into Cline or Cursor, the free SKILL.md generator turns it into a skill folder you can drop into .agents/skills/.
