The Claude Code setup that replaced my IDE
I stopped opening IDE's The setup Two windows: 1. Claude Desktop App (for research, planning, long conversations) 2. Mac terminal running Claude Code (for all execution) Why this works better than running Claude Code inside an IDE When Claude Code runs inside an IDE terminal, every file operation passes through the editor's plugin layer: file watchers, extensions, lock conflicts. In a standalone terminal, Claude Code talks directly to your filesystem. No interception, no translation. The practical difference: - File writes are instant. No "file changed externally, reload?" dialogs. - Git operations run clean. No source control extension competing for the same lock. - Shell access is unfiltered. Package installs, curl, deployment scripts, SSH tunnels. All native. - No extension memory overhead. My terminal session uses a fraction of what VSCode was consuming. - MCP servers (GitHub, databases, APIs) wire in directly without fighting IDE plugin architecture. What a real session looks like Last week I built a Cloudflare Worker with KV bindings. One terminal window: - Claude Code scaffolded the project structure - Wrote the Worker handler, wrangler config, and KV namespace bindings - Ran wrangler deploy - Tested the endpoint with curl - Fixed a routing issue based on the error response - Committed and pushed Total time: under 20 minutes. I never typed a line of code. I described what I needed, reviewed the output, approved the operations. You're not coding in a terminal. You're directing an agent that codes for you. How to set this up (10 minutes) If you have a Mac and Claude Pro or Max: (On a PC? Your setup instructions are in the attached file.) 1. Install Claude Code: open terminal, run the install command from Anthropic's docs. 2. Run "claude" in any project directory. You're in an agentic session. 3. Open Claude Desktop App alongside for planning, research, and longer thinking conversations. Optional but useful: - Set up a .claude directory in your project with a CLAUDE.md file. Same idea as onboarding docs, but for your coding agent. Persistent instructions about your project, coding standards, and preferences.
