DeepClaude - Cutting Claude Code Agent Loop Costs 17x Using DeepSeek V4 Pro

DeepClaude is an open-source project that keeps Claude Code CLI's tool loop, file editing, Bash, and Git flow intact while allowing you to swap out just the API call target to DeepSeek V4 Pro, OpenRouter, Fireworks AI, and more.

While Anthropic's Claude Code has a $200/month fee and usage limits, using DeepSeek V4 Pro through DeepClaude lowers output token costs to around $0.87/M, cutting agent loop costs by up to 17x.

Key Features and Capabilities:

• Support for Multiple Backends: Supports DeepSeek (default), OpenRouter, Fireworks AI, and Anthropic, enabling latency and cost optimization by model.
• Preserved Agent Workflow: Supports file read/write, Bash/PowerShell execution, Glob/Grep search, multi-step autonomous tool loops, subagent creation, and Git operations.
• Live Switching: Instantly switch backends mid-session using commands like /deepseek and /anthropic without restarting.
• Cost Tracking and Proxy: A local proxy calculates token usage and savings compared to Anthropic in real time.
• IDE and Remote Support: Can be run as a VS Code/Cursor terminal profile, and the --remote option lets you open sessions in a browser as well.
