The free build of Claude Code. 
 All telemetry stripped. All guardrails removed. All experimental features unlocked. 
 One binary, zero callbacks home.

---

## Quick Install

```bash
curl -fsSL https://raw.githubusercontent.com/paoloanzn/free-code/main/install.sh | bash
```

Checks your system, installs Bun if needed, clones the repo, builds with all experimental features enabled, and symlinks `free-code` on your PATH.

Then run `free-code` and use the `/login` command to authenticate with your preferred model provider.

## What is this

A clean, buildable fork of Anthropic's [Claude Code](https://docs.anthropic.com/en/docs/claude-code) CLI -- the terminal-native AI coding agent. The upstream source became publicly available on March 31, 2026 through a source map exposure in the npm distribution.

This fork applies three categories of changes on top of that snapshot:

### Telemetry removed

The upstream binary phones home through OpenTelemetry/gRPC, GrowthBook analytics, Sentry error reporting, and custom event logging. In this build:

- All outbound telemetry endpoints are dead-code-eliminated or stubbed
- GrowthBook feature flag evaluation still works locally (needed for runtime feature gates) but does not report back
- No crash reports, no usage analytics, no session fingerprinting

### Security-prompt guardrails removed

Anthropic injects system-level instructions into every conversation that constrain Claude's behavior beyond what the model itself enforces. These include hardcoded refusal patterns, injected "cyber risk" instruction blocks, and managed-settings security overlays pushed from Anthropic's servers.

This build strips those injections. The model's own safety training still applies -- this just removes the extra layer of prompt-level restrictions that the CLI wraps around it.

### Experimental features unlocked

Claude Code ships with 88 feature flags gated behind `bun:bundle` compile-time switches. Most are disabled in the public npm release. This build unlocks all 54 flags that compile cleanly. See [Experimental Features](#experimental-features) below, or refer to [FEATURES.md](FEATURES.md) for the full audit.

## Model Providers

free-code supports **five API providers** out of the box. Set the corresponding environment variable to switch providers -- no code changes needed.

### Anthropic (Direct API) -- Default

Use Anthropic's first-party API directly.

| Model | ID |
|---|---|
| Claude Opus 4.6 | `claude-opus-4-6` |
| Claude Sonnet 4.6 | `claude-sonnet-4-6` |
| Claude Haiku 4.5 | `claude-haiku-4-5` |

### OpenAI Codex

Use OpenAI's Codex models for code generation. Requires a Codex subscription.

| Model | ID |
|---|---|
| GPT-5.3 Codex (recommended) | `gpt-5.3-codex` |
| GPT-5.4 | `gpt-5.4` |
| GPT-5.4 Mini | `gpt-5.4-mini` |

```bash
export CLAUDE_CODE_USE_OPENAI=1
free-code
```

### AWS Bedrock

Route requests through your AWS account via Amazon Bedrock.

```bash
export CLAUDE_CODE_USE_BEDROCK=1
export AWS_REGION="us-east-1"   # or AWS_DEFAULT_REGION
free-code
```

Uses your standard AWS credentials (environment variables, `~/.aws/config`, or IAM role). Models are mapped to Bedrock ARN format automatically (e.g., `us.anthropic.claude-opus-4-6-v1`).

| Variable | Purpose |
|---|---|
| `CLAUDE_CODE_USE_BEDROCK` | Enable Bedrock provider |
| `AWS_REGION` / `AWS_DEFAULT_REGION` | AWS region (default: `us-east-1`) |
| `ANTHROPIC_BEDROCK_BASE_URL` | Custom Bedrock endpoint |
| `AWS_BEARER_TOKEN_BEDROCK` | Bearer token auth |
| `CLAUDE_CODE_SKIP_BEDROCK_AUTH` | Skip auth (testing) |

### Google Cloud Vertex AI

Route requests through your GCP project via Vertex AI.

```bash
export CLAUDE_CODE_USE_VERTEX=1
free-code
```

Uses Google Cloud Application Default Credentials (`gcloud auth application-default login`). Models are mapped to Vertex format automatically (e.g., `claude-opus-4-6@latest`).

### Anthropic Foundry

Use Anthropic Foundry for dedicated deployments.

```bash
export CLAUDE_CODE_USE_FOUNDRY=1
export ANTHROPIC_FOUNDRY_API_KEY="..."
free-code
```

Supports custom deployment IDs as model names.

### Provider Selection Summary

| Provider | Env Variable | Auth Method |
|---|---|---|
| Anthropic (default) | -- | `ANTHROPIC_API_KEY` or OAuth |
| OpenAI Codex | `CLAUDE_CODE_USE_OPENAI=1` | OAuth via OpenAI |
| AWS Bedrock | `CLAUDE_CODE_USE_BEDROCK=1` | AWS credentials |
| Google Vertex AI | `CLAUDE_CODE_USE_VERTEX=1` | `gcloud` ADC |
| Anthropic Foundry | `CLAUDE_CODE_USE_FOUNDRY=1` | `ANTHROPIC_FOUNDRY_API_KEY` |

---

## Requirements

- **Runtime**: [Bun](https://bun.sh) >= 1.3.11
- **OS**: macOS or Linux (Windows via WSL)
- **Auth**: An API key or OAuth login for your chosen provider

```bash
# Install Bun if you don't have it
curl -fsSL https://bun.sh/install | bash
```

---

## Build

```bash
git clone https://github.com/paoloanzn/free-code.git
cd free-code
bun build
./cli
```

### Build Variants

| Command | Output | Features | Description |
|---|---|---|---|
| `bun run build` | `./cli` | `VOICE_MODE` only | Production-like binary |
| `bun run build:dev` | `./cli-dev` | `VOICE_MODE` only | Dev version stamp |
| `bun run build:dev:full` | `./cli-dev` | All 54 experimental flags | Full unlock build |
| `bun run compile` | `./dist/cli` | `VOICE_MODE` only | Alternative output path |

### Custom Feature Flags

Enable specific flags without the full bundle:

```bash
# Enable just ultraplan and ultrathink
bun run ./scripts/build.ts --feature=ULTRAPLAN --feature=ULTRATHINK

# Add a flag on top of the dev build
bun run ./scripts/build.ts --dev --feature=BRIDGE_MODE
```

---

## Usage

```bash
# Interactive REPL (default)
./cli

# One-shot mode
./cli -p "what files are in this directory?"

# Specify a model
./cli --model claude-opus-4-6

# Run from source (slower startup)
bun run dev

# OAuth login
./cli /login
```

### Environment Variables Reference

| Variable | Purpose |
|---|---|
| `ANTHROPIC_API_KEY` | Anthropic API key |
| `ANTHROPIC_AUTH_TOKEN` | Auth token (alternative) |
| `ANTHROPIC_MODEL` | Override default model |

## Contributing

Contributions are welcome. If you're working on restoring one of the 34 broken feature flags, check the reconstruction notes in [FEATURES.md](FEATURES.md) first -- many are close to compiling and just need a small wrapper or missing asset.

1. Fork the repository
2. Create a feature branch (`git checkout -b feat/my-feature`)
3. Commit your changes (`git commit -m 'feat: add something'`)
4. Push to the branch (`git push origin feat/my-feature`)
5. Open a Pull Request
