Claude Code: programming and automation with AI

Claude Code is Anthropic's agentic coding tool. It works in the terminal, the IDE and on the web, reads your codebase, edits files, runs commands and completes a task step by step. I used it to build this site's code too.

What is Claude Code?

You give Claude Code a task in plain language: "add a form to this page and save it to Supabase". It explores the project, makes a plan, writes the code, runs the tests and submits the change for your approval.

It is very useful for marketing technology: tracking scripts, data pipelines, landing pages and internal tools are ready in days, not weeks. Code review and security rules still matter.

What Claude Code makes possible

  1. Writing and refactoring code

    With the whole project as context.

  2. Debugging

    Reads the logs and shows the cause.

  3. Tests

    Writes and runs tests.

  4. Git workflow

    Preparing commits and pull requests.

  5. Scripts and automation

    Data and reporting scripts.

  6. MCP integrations

    External tools and data sources.

Questions about Claude Code

Can a non-programmer use it?

For simple scripts and prototypes, yes. For production code someone who knows the result should review it.

Is my code safe?

Claude Code makes changes with your permission. Secrets (API keys, passwords) should never go into code or chat.

Which languages does it know?

It works with all major programming languages and frameworks: JavaScript, Python, SQL and others.
