KlowCode

The AI coding agent that works for you — not Anthropic.
No telemetry. No guardrails. No phone-home. All 54 experimental features unlocked.
One command. Full power.

Install Stars Issues Feature Flags IPFS Platform

KlowCode is a fully unlocked, privacy-first build of the Claude Code CLI. It speaks to Claude (and 4 other model providers) directly — with zero surveillance, zero artificial restrictions, and every experimental feature Anthropic ships but doesn't let you use.

What makes KlowCode different

Official Claude Code KlowCode
Telemetry / analytics ✅ always on ❌ stripped
Session fingerprinting ✅ ❌
Prompt-level guardrails ✅ injected ❌ removed
Experimental features 0 of 54 54 of 54
Voice input locked ✅
UltraThink / UltraPlan locked ✅
Multi-agent orchestration locked ✅
IDE bridge (VS Code / JetBrains) locked ✅
Works without Claude subscription ❌ ✅ (5 providers)

⚡ Quick Install

Recommended — All Platforms (macOS / Linux / Windows)

Requires Bun >= 1.3.11. Install it first if you don't have it:

  • macOS / Linux: curl -fsSL https://bun.sh/install | bash
  • Windows: powershell -c "irm bun.sh/install.ps1 | iex"
git clone https://github.com/Ahilan-1/klowcode.git
cd klowcode
bun install
bun run build:dev:full
./cli-dev        # macOS / Linux
./cli-dev.exe   # Windows

This builds with all 54 experimental features unlocked.

macOS / Linux — One-liner

curl -fsSL https://raw.githubusercontent.com/Ahilan-1/klowcode/main/install.sh | bash

Automatically installs Bun if needed, clones, builds, and puts klowcode on your PATH.

Then:

klowcode          # launch the interactive REPL
klowcode /login   # authenticate with your provider

🔌 Model Providers

KlowCode works with five providers out of the box. Switch with an environment variable — no code changes needed.

Provider Env Variable Auth
Anthropic (default) — ANTHROPIC_API_KEY or /login OAuth
OpenAI Codex CLAUDE_CODE_USE_OPENAI=1 OpenAI OAuth
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

Anthropic (default)

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 
export ANTHROPIC_API_KEY="sk-ant-..."
