Claude Code running via NVIDIA NIM — completely free

Features

Feature	Description
Zero Cost	40 req/min free on NVIDIA NIM. Free models on OpenRouter. Fully local with LM Studio
Drop-in Replacement	Set 2 env vars — no modifications to Claude Code CLI or VSCode extension needed
3 Providers	NVIDIA NIM, OpenRouter (hundreds of models), LM Studio (local & offline)
Thinking Token Support	Parses `<think>` tags and `reasoning_content` into native Claude thinking blocks
Heuristic Tool Parser	Models outputting tool calls as text are auto-parsed into structured tool use
Request Optimization	5 categories of trivial API calls intercepted locally — saves quota and latency
Discord Bot	Remote autonomous coding with tree-based threading, session persistence, and live progress (Telegram also supported)
Smart Rate Limiting	Proactive rolling-window throttle + reactive 429 exponential backoff across all providers
Subagent Control	Task tool interception forces `run_in_background=False` — no runaway subagents
Extensible	Clean `BaseProvider` and `MessagingPlatform` ABCs — add new providers or platforms easily

Quick Start

Prerequisites

Get an API key (or use LM Studio locally):
- NVIDIA NIM: build.nvidia.com/settings/api-keys
- OpenRouter: openrouter.ai/keys
- LM Studio: No API key needed — run locally with LM Studio
Install Claude Code
Install uv

Clone & Configure

git clone https://github.com/Alishahryar1/free-claude-code.git
cd free-claude-code
cp .env.example .env

Choose your provider and edit .env:

NVIDIA NIM (recommended — 40 req/min free)

PROVIDER_TYPE=nvidia_nim
NVIDIA_NIM_API_KEY=nvapi-your-key-here
MODEL=stepfun-ai/step-3.5-flash

OpenRouter (hundreds of models)

PROVIDER_TYPE=open_router
OPENROUTER_API_KEY=sk-or-your-key-here
MODEL=stepfun/step-3.5-flash:free

LM Studio (fully local, no API key)

PROVIDER_TYPE=lmstudio
MODEL=lmstudio-community/qwen2.5-7b-instruct

Run It

Terminal 1 — Start the proxy server:

uv run uvicorn server:app --host 0.0.0.0 --port 8082

Terminal 2 — Run Claude Code:

ANTHROPIC_AUTH_TOKEN=freecc ANTHROPIC_BASE_URL=http://localhost:8082 claude

That's it! Claude Code now uses your configured provider for free.

VSCode Extension Setup

Start the proxy server (same as above).
Open Settings (Ctrl + ,) and search for claude-code.environmentVariables.
Click Edit in settings.json and add:

"claude-code.environmentVariables": [
  { "name": "ANTHROPIC_BASE_URL", "value": "http://localhost:8082" },
  { "name": "ANTHROPIC_AUTH_TOKEN", "value": "freecc" }
]

Reload extensions.
If you see the login screen ("How do you want to log in?"): Click Anthropic Console, then authorize. The extension will start working. You may be redirected to buy credits in the browser — ignore that; the extension already works.

To switch back to Anthropic models, comment out the added block and reload extensions.

Transparent proxy — Claude Code sends standard Anthropic API requests to the proxy server
Request optimization — 5 categories of trivial requests (quota probes, title generation, prefix detection, suggestions, filepath extraction) are intercepted and responded to instantly without using API quota
Format translation — Real requests are translated from Anthropic format to the provider's OpenAI-compatible format and streamed back
Thinking tokens — <think> tags and reasoning_content fields are converted into native Claude thinking blocks so Claude Code renders them correctly

Providers

Provider	Cost	Rate Limit	Models	Best For
NVIDIA NIM	Free	40 req/min	Kimi K2, GLM5, Devstral, MiniMax	Daily driver — generous free tier
OpenRouter	Free / Pay	Varies	200+ (GPT-4o, Claude, Step, etc.)	Model variety, fallback options
LM Studio	Free (local)	Unlimited	Any GGUF model	Privacy, offline use, no rate limits

Switch providers by changing PROVIDER_TYPE in .env:

Provider	`PROVIDER_TYPE`	API Key Variable	Base URL
NVIDIA NIM	`nvidia_nim`	`NVIDIA_NIM_API_KEY`	`integrate.api.nvidia.com/v1`
OpenRouter	`open_router`	`OPENROUTER_API_KEY`	`openrouter.ai/api/v1`
LM Studio	`lmstudio`	(none)	`localhost:1234/v1`

OpenRouter gives access to hundreds of models (StepFun, OpenAI, Anthropic, etc.) through a single API. Set MODEL to any OpenRouter model ID.

LM Studio runs locally — start the server in LM Studio's Developer tab or via lms server start, load a model, and set MODEL to the model identifier.

Discord Bot

Control Claude Code remotely from Discord. Send tasks, watch live progress, and manage multiple concurrent sessions. Discord is the default messaging platform; Telegram is also supported.

Capabilities:

Tree-based message threading — reply to messages to fork conversations
Session persistence across server restarts
Live streaming of thinking tokens, tool calls, and results
Up to 10 concurrent Claude CLI sessions
Commands: /stop (cancel tasks), /clear (reset all sessions), /stats

Setup

Create a Discord Bot — Go to Discord Developer Portal, create an application, add a bot, and copy the token. Enable Message Content Intent under Bot settings.
Edit .env:

MESSAGING_PLATFORM=discord
DISCORD_BOT_TOKEN=your_discord_bot_token
ALLOWED_DISCORD_CHANNELS=123456789,987654321

Enable Developer Mode in Discord (Settings → Advanced), then right-click a channel and "Copy ID" to get channel IDs. Comma-separate multiple channels. If empty, no channels are allowed.

Configure the workspace (where Claude will operate):

CLAUDE_WORKSPACE=./agent_workspace
ALLOWED_DIR=C:/Users/yourname/projects

Start the server:

uv run uvicorn server:app --host 0.0.0.0 --port 8082

Invite the bot to your server (OAuth2 → URL Generator, scopes: bot, permissions: Read Messages, Send Messages, Manage Messages, Read Message History). Send a message in an allowed channel with a task. Claude responds with thinking tokens, tool calls as they execute, and the final result. Reply /stop to a running task to cancel it.

Telegram (Alternative)

To use Telegram instead, set MESSAGING_PLATFORM=telegram and configure:

TELEGRAM_BOT_TOKEN=123456789:ABCdefGHIjklMNOpqrSTUvwxYZ
ALLOWED_TELEGRAM_USER_ID=your_telegram_user_id

Get a token from @BotFather; find your user ID via @userinfobot.

Extending

Adding a Provider

Extend BaseProvider in providers/ to add support for other APIs:

from providers.base import BaseProvider, ProviderConfig

class MyProvider(BaseProvider):

        # Yield Anthropic SSE format events
        ...

Adding a Messaging Platform

Extend MessagingPlatform in messaging/ to add Slack or other platforms:

from messaging.base import MessagingPlatform

class MyPlatform(MessagingPlatform):
    async def start(self):
        # Initialize connection
        ...

    async def stop(self):
        # Cleanup
        ...

    async def send_message(self, chat_id, text, reply_to=None, parse_mode=None):
        # Send a message
        ...

    async def edit_message(self, chat_id, message_id, text, parse_mode=None):
        # Edit an existing message
        ...

    def on_message(self, handler):
        # Register callback for incoming messages
        ...
