KeyKing - The Zero-Trust Free AI API Aggregator to run Free Claude Code and Manage API Keys Locally.
One API Key.
Every
AI Model.
Stop pasting your real API keys into every new project. KeyKing securely stores your keys on your computer and gives you one universal local endpoint. It automatically switches providers if you hit a rate limit.
The Universal AI Catalog
Over 255+ providers and 1,000+ models with zero-trust local routing. From massive free monthly tiers (Mistral, Gemini, Groq, Cerebras) to full aggregator gateways (BazaarLink, OpenRouter) and Claude Code relays (AgentRouter, Lumos). Drop in your keys and code seamlessly.
AI Context Manager &
Codebase Reverse-Engineering
Got a raw codebase with zero documentation? KeyKing scans your files, package manifests, and schemas to synthesize dense, zero-bloat architecture specs. When you drop markdown files or PRDs, AI strips conversational filler and prioritizes core invariants before sending to Claude, Cursor, or Aider.
1. Auto Codebase Derivation
No docs needed. KeyKing indexes directory structures, database schemas (Prisma, SQL), API routes, and core types into 3 dense architecture blueprints: Architecture Overview, Data Models & Schema, and API Surface Map.
2. Zero-Bloat AI Debloating
Drop architecture documents or PRDs. The AI removes conversational preambles, repetitive examples, and formatting fluff, cutting token consumption by up to 80% and sorting by High/Medium/Low priority.
3. Auto-Primed Agent Launch
Run keyking run or keyking claude. KeyKing injects your active sprint goal, git branch context, and distilled high-priority artifacts directly into the agent's priming kick-off prompt.
One Gateway, Five Powerful Capabilities
KeyKing v4.0.0 unites universal multi-provider local routing, AI codebase reverse-engineering, zero-bloat context distillation, and seamless agent interception under one unified local engine.
Desktop Proxy
Ideal for vibe-coding. Run the high-performance Rust proxy binding to localhost:8787. Route Cursor, Claude Code, Aider, OpenCode, and local scripts with automated token telemetry and zero dotfile leaks.
Codebase Reverse-Engineering
Zero documentation? KeyKing scans manifests, routes, and schemas to auto-derive high-density architecture specs. Auto-debloats dropped docs by priority to cut context bloat by up to 80% with zero repo dotfiles.
Zero-Config Agent Wrappers
Run Claude Code, Aider, OpenCode, and Codex with one command: keyking run or keyking-claude. Pre-primed with distilled codebase context and routed through 255+ providers.
Serverless SDK
Deploy to production using @keyking/sdk. Purpose-built for serverless environments (Vercel, AWS Lambda, Cloudflare Workers) to unpack encrypted vaults in memory with zero cloud lock-in.
Hardware Derived Vault
Secure local credential management. Encrypts all your LLM provider API keys using hardware-derived AES-256-GCM + PBKDF2. Keys never touch third-party servers or telemetry collectors.
Priority Fallback Ladders
Automatic failovers across 255+ providers. If Anthropic or OpenAI returns a 429 rate limit, requests instantly cascade to DeepSeek, Mistral, Gemini, or Groq with zero broken connections.
