What is agentic coding? - Comparison

Claude Code, GitHub Copilot, and Cursor take three distinct approaches to AI-assisted coding. Claude Code focuses on agentic autonomy in the terminal, Copilot on native VS Code integration, and Cursor on a dedicated AI IDE. Choose according to your profile: maximum autonomy, quick completion, or guided refactoring.

Agentic coding is an approach where an AI agent executes development tasks end-to-end - code reading, file editing, command execution - without manual intervention at each step. Three tools dominate this market: Claude Code (Anthropic), GitHub Copilot (Microsoft/OpenAI), and Cursor (Anysphere).

Understanding their differences lets you choose the assistant that matches your daily workflow. For an in-depth definition, see the article What is agentic coding? published on SFEIR Institute.

Key takeaway: Claude Code excels in terminal autonomy, Copilot in IDE integration, Cursor in interactive refactoring.

What distinguishes agentic coding from traditional autocompletion?

Traditional autocompletion predicts the next line of code. Agentic coding goes further: the AI understands the overall objective, plans the steps, and executes modifications across multiple files.

In practice, an agent like Claude Code can receive the instruction "add a REST endpoint with tests" and create the route file, the controller, the unit tests, and update the documentation - all in a single command.

In practice, a developer saves between 30 and 55% of time on repetitive tasks with an autonomous agent, versus 15 to 25% with autocompletion alone. The agentic coding FAQ answers frequent questions about this approach.

The agentic coding glossary defines each technical term you will encounter in this article.

Key takeaway: agentic coding automates entire flows where autocompletion is limited to the next line.

What are the strengths and weaknesses of Claude Code?

Key takeaway: Copilot remains the default choice for fast autocompletion integrated into the IDE.

How does Cursor position itself against its competitors?

Cursor is a complete IDE based on a fork of VS Code, designed from the ground up for AI-assisted development. it offers an Agent mode capable of editing multiple files simultaneously via its Composer feature.

# Installing Cursor on macOS
brew install --cask cursor

Strengths:

• Dedicated IDE with AI-optimized UX
• Composer mode for multi-file editing
• Automatic codebase indexing for rich context
• Integration of multiple models (GPT-4o, Claude Sonnet)
• Built-in visual diff for validating modifications

Weaknesses:

• Requires leaving VS Code for a fork
• VS Code extensions sometimes incompatible
• No autonomous system command execution
• Same price as Copilot with fewer native integrations

Cursor claims 40,000 enterprise users and adoption growth of 300% between 2024 and 2025. Its Composer mode handles refactorings across an average of 15 files in 90 seconds.

Permissions and security are a major selection criterion: check how each tool manages access to your files.

Key takeaway: Cursor suits developers who want an all-in-one IDE centered on AI.

How much do these tools cost in 2026?

Compare the pricing models to choose according to your budget and usage. The prices below reflect the offers in effect as of February 2026.

In practice, a developer using Claude Code intensively consumes between $150 and $900 in API credits per month according to Anthropic. The Max plan at $200/month offers unlimited usage for intensive users.

Specifically, Copilot remains the most accessible for teams already on GitHub Enterprise. Total cost depends on request volume and chosen model.

To get started without extra cost, follow the installation and first launch guide which details the initial configuration step by step.

Key takeaway: all three tools sit around $20/month for individual use, but Claude Code's API cost varies with intensity.

Which use cases should you prioritize for each tool?

Each tool excels in specific scenarios. Identify your primary use case to make the right choice.

Here is how to choose in 3 questions:

1. Do you work primarily in the terminal? -> Claude Code
2. Do you want to stay in VS Code without changes? -> Copilot
3. Are you looking for a dedicated AI IDE with visual diff? -> Cursor

You can also combine these tools. In practice, 35% of developers use two AI assistants simultaneously according to Stack Overflow (2025). The Claude Code comparison page deepens the technical benchmarks.

Key takeaway: there is no universal best tool - the choice depends on your daily workflow.

How do you configure Claude Code for an optimal agentic workflow?

Launch Claude Code in your project and configure the CLAUDE.md file to customize the agent's behavior:

cd your-project
claude
# In the Claude Code session:
/init

This command generates a CLAUDE.md file at the project root. Edit it to define your conventions:

# CLAUDE.md
- Language: TypeScript strict
- Tests: Vitest, coverage >80%
- Style: ESLint + Prettier
- Commits: conventional commits (feat:, fix:, chore:)

Check permissions with the command:

claude config permissions

The first conversations guide walks you through formulating effective instructions. Claude Code supports Node.js 22 LTS and works on macOS, Linux, and WSL 2.

Here is how to validate your configuration in 60 seconds: run claude "describe this project" and verify that the agent correctly identifies the technical stack, dependencies, and file structure.

Specifically, a well-written CLAUDE.md file reduces the number of iterations needed to get a result that meets your standards by 40%.

If you want to go beyond basic configuration, the AI-Augmented Developer training from SFEIR Institute offers 2 days of hands-on labs covering Claude Code, Copilot, and Cursor with real enterprise use cases. For experienced profiles, the AI-Augmented Developer - Advanced training deepens multi-agent workflows and optimization strategies in 1 intensive day.
