| Gemini CLI | Growing | Yes | Gemini 2.0 | Free tier available | Google ecosystem, large context needs |
Claude Code
Claude Code is Anthropic's terminal-based AI coding tool. It's deliberately text-first — no GUI, no IDE integration, just a powerful command-line agent.
Strengths:
- The most capable agent mode of any tool on this list. Claude Code can autonomously plan and execute multi-step coding tasks, run tests, fix failures, and iterate until the work is done.
- Native MCP support with the cleanest integration. Adding servers is one command (
claude mcp add), and the tool handles server lifecycle automatically. - Full filesystem access by default. You don't need to configure anything to have the agent read and write files.
- Works in any editor — because it's terminal-based, it pairs with VS Code, Neovim, JetBrains, or whatever you prefer.
Weaknesses:
- No inline completion or autocomplete. It's an agent tool, not an autocomplete tool — if you want suggestions as you type, you need something else.
- The terminal interface isn't for everyone. Developers who prefer GUI tools will find it uncomfortable.
- Costs can add up quickly for heavy users. With the most capable models, long agentic sessions get expensive.
MCP integration: Full support. The most seamless MCP experience of any tool.
Pricing: Pay-per-token via API. Roughly $3-15/hour for active agentic sessions depending on model and task complexity.
Best for: Developers who want the most capable AI agent and are comfortable in the terminal. Excellent for complex, multi-session projects with MCP servers like Planu for spec management.
Cursor
Cursor is a VS Code fork with deep AI integration. It's the most polished IDE-first AI tool available.
Strengths:
- Inline code completion that's genuinely better than Copilot for most tasks.
- Agent mode (formerly Composer) handles multi-file changes well.
- Model flexibility — you can use Claude, GPT-4o, or Gemini in the same tool.
- The codebase indexing is thorough. Cursor actually understands your project structure, not just the current file.
Weaknesses:
- It's a VS Code fork, which means it drifts from VS Code features over time and occasionally breaks extensions.
- Agent mode is good but not as autonomous as Claude Code. It often pauses to ask for confirmation on things a more capable agent would handle.
- MCP support exists but is less mature than Claude Code's.
MCP integration: Full support via ~/.cursor/mcp.json. Works in Agent mode only.
Pricing: Free tier (limited), $20/month Pro (2000 fast requests), Team plans available.
Best for: Developers who want to stay in an IDE, want inline autocomplete plus agent mode, and are comfortable with VS Code's extension ecosystem.
Windsurf
Windsurf by Codeium takes a hybrid approach — it excels at fast tab completion while also offering Cascade, a capable agent mode.
Strengths:
- The tab completion (called Supercomplete) is the fastest and most context-aware of any tool here. It predicts not just the next line but the next logical code block.
- Cascade agent mode is solid for mid-complexity tasks.
- Strong performance on large codebases — Codeium has invested heavily in efficient indexing.
- More affordable than Cursor for similar features.
Weaknesses:
- Agent mode is less capable than Cursor's or Claude Code's for genuinely complex multi-step tasks.
- MCP support is newer and occasionally has compatibility issues.
- Smaller model ecosystem — primarily Claude and GPT-4o.
MCP integration: Partial support via ~/.windsurf/mcp_config.json. Growing rapidly.
Pricing: Free tier, $15/month Pro. Good value.
Best for: Developers who want the best tab completion experience and want agent capabilities as a secondary feature.
GitHub Copilot
GitHub Copilot has evolved significantly from its early autocomplete-only days. It now includes an agent mode that can handle multi-file changes.
Strengths:
- Native VS Code integration — if you're already using VS Code and GitHub, the friction to get started is near zero.
- The Enterprise tier includes codebase-aware features and private model fine-tuning.
- GitHub-specific features (PR reviews, issue summarization) are genuinely useful for teams.
- Cheapest entry price for individual developers.
Weaknesses:
- Agent mode lags behind Claude Code and Cursor in capability.
- MCP support is limited compared to other tools.
- The underlying models (primarily GPT-4o) are strong but not always the best for coding tasks.
- Less flexible for power users who want to configure things deeply.
MCP integration: Limited. Basic MCP support added in 2025, but not fully mature.
Pricing: $10/month Individual, $19/month Business, Enterprise custom pricing.
Best for: Teams already on GitHub who want integrated PR reviews and code suggestions without changing editors. Good starting point for developers new to AI coding tools.
Cline
Cline is an open-source VS Code extension that acts as a full AI coding agent. The key differentiator: you bring your own API key and choose any model.
Strengths:
- Full MCP support — Cline has one of the best MCP implementations of any tool.
- Complete model flexibility. Use Claude, GPT-4o, Gemini, local models via Ollama, or any OpenAI-compatible API.
- Open source — you can inspect the code, fork it, or contribute.
- No subscription cost. You pay only for model usage (API costs).
Weaknesses:
- Requires more configuration than commercial tools.
- No tab completion — it's agent-only.
- UX is rougher than Cursor or Windsurf.
- Support is community-driven, not a commercial team.
MCP integration: Excellent. Full MCP support, easy server management through the VS Code UI.
Pricing: Free (you pay API costs directly). Very cost-effective for moderate usage with efficient prompting.
Best for: Power users who want full control over models and configuration, value open source, and are comfortable with more DIY setup.
Gemini CLI
Google's Gemini CLI is a terminal-based AI coding tool similar in concept to Claude Code but built on the Gemini model family.
Strengths:
- Gemini 2.0's context window is extremely large (up to 1M tokens), which helps with very large codebases.
- The free tier is generous — useful for exploration and lighter workflows without API costs.
- Strong integration with Google services (Drive, Docs, etc.).
- Improving rapidly — Google has been shipping updates frequently.
Weaknesses:
- Agent capabilities are behind Claude Code for complex multi-step tasks.
- MCP support is newer and still growing.
- Gemini models, while strong, are not consistently the best for code in head-to-head comparisons.
- Less community tooling and ecosystem than Claude Code.
MCP integration: Growing. Basic MCP support, expanding.
Pricing: Free tier available, pay-per-token for heavier usage via Google AI Studio or Vertex AI.
Best for: Google ecosystem users, developers who need very large context windows, and anyone who wants a capable free-tier option.
How to Choose
There's no single best tool — it depends on what you actually do.
Choose Claude Code if: You want the most capable agentic AI, work heavily with MCP servers, and are comfortable in the terminal.
Choose Cursor if: You want an IDE-first experience with great inline completion and solid agent capabilities.
Choose Windsurf if: Fast, context-aware tab completion is your priority and you want agent mode as a bonus.
Choose GitHub Copilot if: You're a VS Code + GitHub user who wants smooth integration without setup complexity.
Choose Cline if: You want full control over models, value open source, and use MCP servers heavily.
Choose Gemini CLI if: You work in the Google ecosystem, need massive context windows, or want a capable free-tier option.
They're not mutually exclusive
Many developers use multiple tools. A common setup: Cursor for daily coding (inline completion + refactoring), Claude Code for complex multi-session projects, Cline for tasks that need a specific model.
The MCP Advantage
Whichever tool you choose, MCP servers significantly extend what's possible. A tool like Planu, which gives your AI agent a full spec management system, works with all of these tools — though the setup varies.
The tools with the best MCP support (Claude Code, Cline, Cursor) get the most value from the growing ecosystem of servers.
