brcc is a local proxy that lets you run Claude Code with any LLM model — GPT-5, Claude, Gemini, DeepSeek, Grok, and 40+ more — without rate limits, without an Anthropic account, and without phone verification. You pay per request with USDC via the x402 protocol. Your wallet is your identity. Your private key never leaves your machine.

Why brcc exists

Claude Code users are frustrated. Over 4,350 GitHub issue comments about the same problems:

| | Issue | Comments | |--|-------|----------| | 🔴 | "Instantly hitting usage limits with Max subscription" | 1,252 | | 🔴 | "Phone verification — unable to send code" | 546 | | 🔴 | "Account disabled after payment" | 145 | | 🔴 | "5-hour limit reached in less than 1h30" | 108 | | 🔴 | "Rate limit reached despite Max subscription and only 16% usage" | 89 |

Every one of these people is a potential brcc user.

brcc eliminates all of these problems:

• No rate limits — pay per request, use as much as you want
• No account — a wallet is generated locally, no signup
• No phone verification — USDC is your authentication
• No region restrictions — works everywhere, priced the same
• No billing surprises — transparent per-token pricing

How it compares

| | Claude Max ($200/mo) | OpenRouter | brcc | |--|---------------------|------------|----------| | Rate limits | Constantly hit | Per-model limits | None | | Account required | Yes + phone | Yes + email | No | | Models | Claude only | 200+ (manual select) | 40+ (auto or manual) | | Payment | Credit card, subscription | Credit card, pre-pay | USDC per-request | | Auth | OAuth + API key conflicts | API key | Wallet signature | | Pricing | Opaque | Transparent | Transparent | | Runs locally | N/A | No | Yes (proxy) | | Monthly cost | $100-200 fixed | Varies | $5-50 based on usage |

Quick Start

One-line install (Linux/macOS)

curl -fsSL https://raw.githubusercontent.com/BlockRunAI/brcc/main/install.sh | bash

Installs Node.js (if needed) + Claude Code + brcc + creates wallet.

Manual install

# 1. Install Claude Code
curl -fsSL https://claude.ai/install.sh | bash

# 2. Install brcc (use sudo on Linux)
sudo npm install -g @blockrun/cc  # use sudo on Linux

# 3. Create wallet
brcc setup base      # Base chain (Coinbase L2)
# or
brcc setup solana    # Solana chain

# 4. Fund your wallet with USDC (or use free models without funding)

# 5. Launch
brcc start

That's it. Claude Code opens with access to 40+ models, no rate limits.

Choosing Models

From the command line

brcc start                                # Default (Claude Sonnet 4.6)
brcc start --model nvidia/gpt-oss-120b    # Free — no USDC needed
brcc start --model openai/gpt-5.4         # GPT-5.4
brcc start --model deepseek/deepseek-chat # Budget coding ($0.28/M)
brcc start --model anthropic/claude-opus-4.6  # Most capable

Inside Claude Code

Use /model to switch between Sonnet, Opus, and Haiku. Each maps to the BlockRun model you've configured:

# Customize what each /model option routes to
brcc config set sonnet-model anthropic/claude-sonnet-4.6    # default
brcc config set opus-model anthropic/claude-opus-4.6        # default
brcc config set haiku-model deepseek/deepseek-chat          # cheap alternative

Your private key stays on your machine. Only payment signatures are sent.

Funding Your Wallet

brcc uses USDC — a dollar-pegged stablecoin. No crypto volatility.

Base chain (default):

1. Buy USDC on Coinbase
2. Send to your brcc wallet address (shown in brcc setup)
3. Make sure it's on Base network (not Ethereum mainnet)

Solana chain:

1. Buy USDC on any exchange
2. Send to your brcc Solana address
3. Send on Solana network

Typical cost: $0.001–$0.05 per interaction. $5 lasts most developers a week.

FAQ

Do I need an Anthropic account? No. brcc connects Claude Code to BlockRun instead of Anthropic.

Can I use non-Claude models? Yes. GPT-5, Gemini, DeepSeek, Grok, and 30+ others work through Claude Code via brcc.
