4. Claude Code
Category: IDE-agents
Pricing: Free tier (limited)
- Natural-language prompt → plan → code generation & editing.
- Available as a web app (claude.ai/code) with GitHub integration and as a desktop app with local file access, visual diffs, and Cowork background agents.
Use case: Users preferring Anthropic’s model and a seamless web-to-desktop workflow.
5. Claude Code CLI
Category: IDE-agents (terminal)
Pricing: Requires Claude Pro/Max/Team subscription
