⚡ Quick Verdict
Choose Cline for autonomous multi-step tasks, browser automation, terminal execution, and custom MCP tools. Choose Continue for inline code assistance, JetBrains support, and seamless chat-based Q&A in your IDE.
Bottom line: Cline is the "do it for me" agent. Continue is the "help me do it" assistant. Both are free with BYOK pricing—you can even use both together for different tasks.
📊 At a Glance
🧠 Different Philosophies
These tools solve AI-assisted coding in fundamentally different ways:
🔵 Cline: The Autonomous Agent
Cline takes over. Give it a task like "refactor the auth system" and watch it plan, execute terminal commands, modify files, even launch a browser to test. You approve each step (human-in-the-loop), but Cline drives. Think of it as a junior developer you're supervising.
🟣 Continue: The IDE Autopilot
Continue assists. Highlight code, ask a question, get an answer. Use slash commands for common tasks. It integrates into your natural editing flow rather than taking over. Think of it as a knowledgeable coworker sitting next to you.

⚙️ Workflow Comparison
See how each tool handles a typical coding task:
🔵 Cline: "Add user authentication"
- Type task in Cline panel
- Cline plans: "I'll create auth routes, middleware, and user model"
- Shows diff for auth/routes.js → Approve
- Shows diff for middleware/auth.js → Approve
- Runs:
npm install jsonwebtoken bcrypt→ Approve - Launches browser to test login flow
- Reports: "Auth system implemented and tested"
🟣 Continue: "Add user authentication"
- Open chat, type question
- Continue explains auth approach with code samples
- Use /edit to generate route file
- Ask follow-up: "How do I hash passwords?"
- Get bcrypt code snippet, paste it
- Use @codebase to find related files
- Manually run npm install and test
Key difference: Cline executes autonomously with your approval at each step. Continue guides you through doing it yourself.

→ Continue🔄 Complex Refactoring
Rename patterns across codebase, update APIs, migrate frameworks.
→ Cline💡 Can You Use Both Together?
Yes! Many developers run both Cline and Continue in VS Code simultaneously:
- Continue for quick questions, inline chat, and tab autocomplete
- Cline for complex tasks, browser testing, and MCP tools
- Both use BYOK, so you can share the same API keys
- No conflicts—they use different UI elements
This combo gives you the best of both worlds: seamless assistance AND autonomous execution.
❓ Frequently Asked Questions
Is Cline or Continue better for coding?
Cline is better for autonomous multi-step tasks, browser automation, and creating custom tools via MCP. Continue is better for inline code assistance, chat-based Q&A, and developers using JetBrains IDEs. Both are free and open-source with BYOK pricing.
Does Continue support JetBrains like IntelliJ?
Yes! Continue supports both VS Code and JetBrains IDEs (IntelliJ, PyCharm, WebStorm, etc.). This is a key advantage over Cline, which only works with VS Code. If you're a JetBrains user, Continue is your main open-source BYOK option.
Can Cline use a browser for debugging?
Yes! Cline has full browser automation—it can launch a headless browser, click elements, fill forms, scroll, and capture screenshots plus console logs. Continue does not have browser automation capabilities. This makes Cline better for E2E testing and visual debugging.
Which is more autonomous - Cline or Continue?
Cline is significantly more autonomous. It can execute multi-step tasks, run terminal commands, create/modify files, and use the browser—all with human-in-the-loop approval. Continue is more of an assistant that helps with specific tasks rather than executing complex workflows independently.
Which has better tab autocomplete?
Continue wins here—it has native tab autocomplete built in, similar to GitHub Copilot. Cline doesn't include autocomplete; it's focused on task execution rather than inline suggestions. If autocomplete is important, pair Cline with Continue or use a separate autocomplete tool.
Are Cline and Continue both free?
Yes, both are 100% free and open-source under Apache 2.0 license. Both use BYOK (bring your own key) so you pay only for API costs from your chosen provider (Anthropic, OpenAI, etc.) or use free local models via Ollama.
🔄 Alternatives to Consider
Cursor
AI-first IDE with Agent mode. $20/mo subscription vs BYOK. More polished but proprietary.
Aider
CLI-based AI coding. Git-aware with automatic commits. Terminal lovers prefer this.
Windsurf
Another AI IDE with "Cascade" agent mode. Free tier available. VS Code fork.
GitHub Copilot
The original AI autocomplete. $10-19/mo. Best-in-class tab completion.
🏆 Final Verdict
Cline if you want an autonomous agent that executes complex tasks with browser automation and custom tools.
Continue if you want seamless inline assistance, JetBrains support, and tab autocomplete.
