Deepclaude

deepclaude

Use Claude Code's autonomous agent loop with **DeepSeek V4 Pro**, **OpenRouter**, or any Anthropic-compatible backend. Same UX, 17x cheaper.


What this does

Claude Code is the best autonomous coding agent — but it costs $200/month with usage caps. DeepSeek V4 Pro scores 96.4% on LiveCodeBench and costs $0.87/M output tokens.

**deepclaude** swaps the brain while keeping the body:

Your terminal
  +-- Claude Code CLI (tool loop, file editing, bash, git - unchanged)
        +-- API calls -> DeepSeek V4 Pro ($0.87/M) instead of Anthropic ($15/M)

Everything works: file reading, editing, bash execution, subagent spawning, autonomous multi-step coding loops. The only difference is which model thinks.

Quick start (2 minutes)

1. Get a DeepSeek API key

Sign up at [platform.deepseek.com](https://platform.deepseek.com), add $5 credit, copy your API key.

2. Set environment variables

**Windows (PowerShell):**

setx DEEPSEEK_API_KEY "sk-your-key-here"

**macOS/Linux:**

echo 'export DEEPSEEK_API_KEY="sk-your-key-here"' >> ~/.bashrc
source ~/.bashrc

3. Install

**Windows:**

# Copy the script to a directory in your PATH
Copy-Item deepclaude.ps1 "$env:USERPROFILE\.local\bin\deepclaude.ps1"

# Or add the repo directory to PATH
setx PATH "$env:PATH;C:\path\to\deepclaude"

**macOS/Linux:**

chmod +x deepclaude.sh
sudo ln -s "$(pwd)/deepclaude.sh" /usr/local/bin/deepclaude

4. Use it

deepclaude                  # Launch Claude Code with DeepSeek V4 Pro
deepclaude --status         # Show available backends and keys
deepclaude --backend or     # Use OpenRouter (cheapest, $0.44/M input)
deepclaude --backend fw     # Use Fireworks AI (fastest, US servers)
deepclaude --backend anthropic  # Normal Claude Code (when you need Opus)
deepclaude --cost           # Show pricing compari
