README

Start Claude Code

Run Claude Code `v2.1.88` from leaked source — one command setup. Both interactive TUI and non-interactive modes work.

**GitHub**: https://github.com/JiaranI/start-claude-code

![Open source vs Official](screenshot.png)

Quick Start

git clone https://github.com/JiaranI/start-claude-code.git
cd start-claude-code

# Set API key (or use existing OAuth login from official Claude Code)
export ANTHROPIC_API_KEY="sk-ant-xxx"

# Run!
./start.sh

First run will automatically install Bun, dependencies, and configure everything.

Usage

Interactive TUI (full terminal UI)

# With API key
export ANTHROPIC_API_KEY="sk-ant-xxx"
./start.sh --dangerously-skip-permissions

# Or with existing OAuth login (if you've used official Claude Code before)
./start.sh --dangerously-skip-permissions

Non-interactive mode (scripts/pipes)

export ANTHROPIC_API_KEY="sk-ant-xxx"
./start.sh -p "explain this code" --dangerously-skip-permissions < /dev/null

Use a third-party proxy

export ANTHROPIC_BASE_URL="https://your-proxy.com"   # Don't include /v1
export ANTHROPIC_API_KEY="your-key"
export DISABLE_PROMPT_CACHING=1
export DISABLE_INTERLEAVED_THINKING=1
export CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1

# Non-interactive (recommended for proxies)
./start.sh -p "hello" --model claude-sonnet-4-20250514 \
  --dangerously-skip-permissions --no-session-persistence < /dev/null

# Interactive TUI with proxy
./start.sh --model claude-sonnet-4-20250514 --dangerously-skip-permissions --bare

Specify model

./start.sh --model claude-sonnet-4-20250514
./start.sh --model claude-opus-4-20250514
./start.sh --model claude-haiku-4-5-20241022
