deepclaude running Claude Code's agent loop on DeepSeek on Windows

deepclaude is a small open-source tool with a focused job: run Claude Code’s autonomous agent loop against DeepSeek V4 Pro, OpenRouter, or any Anthropic-compatible backend — the same experience, far cheaper. It packages the setup so you’re not assembling environment variables by hand, and it adds routing options on top.

This is the Windows walkthrough and an honest take on when it’s worth it versus the plain manual method. For the manual approach, see run DeepSeek V4 with Claude Code.

What deepclaude does

At heart, deepclaude points Claude Code’s loop at a cheaper backend, the same idea as setting ANTHROPIC_BASE_URL yourself. What it adds is convenience and flexibility: a packaged setup, support for DeepSeek, OpenRouter, and other Anthropic-compatible endpoints, and the routing to make switching easy. The project advertises the same UX as native Claude Code at a fraction of the cost.

Step 1: Get a DeepSeek key

Create a DeepSeek account, add a little credit, and generate an API key. (deepclaude also supports OpenRouter and other backends if you prefer.)

Step 2: Install deepclaude

Follow the install steps in the deepclaude GitHub repository for your platform. It’s a quick install. On Windows, WSL is the smoother environment — see the WSL install guide.

Step 3: Configure and run

Add your DeepSeek API key as the README directs (an environment variable or config entry), pick your backend model, and launch. The tool wires Claude Code’s loop to DeepSeek for you. A typical flow:

# illustrative — follow the repo's exact commands
export DEEPSEEK_API_KEY="sk-your-key"
deepclaude

deepclaude vs the manual method

deepclaude vs manual env vars

deepclaude Packaged setup; multi-backend (DeepSeek, OpenRouter); convenience
Manual ANTHROPIC_BASE_URL No extra tool; two env vars; DeepSeek's native endpoint

If you only want plain DeepSeek with Claude Code, the manual env-var method is two variables and needs no extra software. deepclaude earns its place when you want the packaged convenience, OpenRouter routing, or to switch backends easily. Both get you the same cheap agent loop.

Verify

Start it and run a small task — list files, summarize the README. If Claude Code’s loop runs normally against DeepSeek, you’re set. Watch the DeepSeek dashboard to confirm requests are landing there.

Troubleshooting

  • Auth errors — the API key isn’t set where the tool expects it; recheck the README.
  • Still hitting Anthropic — a leftover ANTHROPIC_BASE_URL may conflict; clear stray variables.
  • Install issues on Windows — try WSL, which most of these tools assume.
  • Unexpected behavior — check the repo’s issues; community tools move fast.

deepclaude checklist

  • DeepSeek (or OpenRouter) API key created
  • deepclaude installed per its GitHub README
  • Backend key configured as directed
  • Launched and tested on a small task
  • Requests confirmed on the provider dashboard

Wrapping up

deepclaude is a quick, packaged way to run Claude Code’s agent loop on DeepSeek or other Anthropic-compatible backends — convenient and flexible, especially if you want OpenRouter routing or easy backend switching. For a single DeepSeek backend, the manual two-variable method is just as effective with nothing extra to maintain. Either way, you get the Claude Code experience at a fraction of the cost.

Frequently asked questions

What is deepclaude?

deepclaude is an open-source tool that runs Claude Code's autonomous agent loop against DeepSeek V4 Pro, OpenRouter, or any Anthropic-compatible backend — the same UX at a fraction of the cost. It packages the configuration so you don't wire up environment variables by hand.

How is it different from just setting ANTHROPIC_BASE_URL?

Functionally it's similar — both point Claude Code's loop at a cheaper backend. deepclaude wraps and simplifies that, and supports routing through OpenRouter and other backends. If you only want plain DeepSeek, the manual env-var method also works; deepclaude adds convenience.

Is it really 5 minutes to set up?

Roughly, yes — install the tool from its GitHub repo, add your DeepSeek (or other) API key, and run. The README has the exact steps. Most of the time is creating the API key and a quick test.

Is it free?

deepclaude is open source and free; you pay only for the backend model (DeepSeek pay-per-token, for example). It's a community project, so check the repo for current status and requirements.

Does it run on Windows?

Yes, though like most of these tools it's smoother in WSL. Follow the repo's instructions for the platform you're on; the concepts are identical.
