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

Install Stars Issues Feature Flags IPFS

--- ## 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. --- ## Table of Contents - [What is this](#what-is-this) - [Model Providers](#model-providers) - [Quick Install](#quick-install) - [Requirements](#requirements) - [Build](#build) - [Usage](#usage) - [Experimental Features](#experimental-features) - [Project Structure](#project-structure) - [Tech Stack](#tech-stack) - [IPFS Mirror](#ipfs-mirror) - [Contributing](#contributing) - [License](#license) --- ## 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 build:icon` | `./assets/logo.ico` | n/a | Generates a multi-size Windows icon from `assets/logo.svg` | | `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 # Windows: compile first, then patch the exe icon with rcedit bun run ./scripts/build.ts --compile --outfile=dist/freeCode.exe --windows-icon=assets/logo.ico ``` --- ## 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 | | `ANTHROPIC_BASE_URL` | Custom API endpoint | | `ANTHROPIC_DEFAULT_OPUS_MODEL` | Custom Opus model ID | | `ANTHROPIC_DEFAULT_SONNET_MODEL` | Custom Sonnet model ID | | `ANTHROPIC_DEFAULT_HAIKU_MODEL` | Custom Haiku model ID | | `CLAUDE_CODE_OAUTH_TOKEN` | OAuth token via env | | `CLAUDE_CODE_API_KEY_HELPER_TTL_MS` | API key helper cache TTL | --- ## Experimental Features The `bun run build:dev:full` build enables all 54 working feature flags.

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 --- ## License The original Claude Code source is the property of Anthropic.
