Keyward – API Key Proxy

Keyward is a local proxy for AI APIs in your menu bar. Instead of pasting your real OpenAI, Anthropic or Google API keys into every tool, each app gets its own virtual key. Keyward swaps it for the real key on your Mac and forwards the request to the provider unchanged.

ONE KEY PER TOOL • Virtual keys for Claude Code, Cursor, scripts, automations and any tool with a configurable base URL • Your real keys live only in the Keychain – never in config files or environment variables • Revoke a single key instantly – without rotating the real key at the provider • Choose which providers each key may use • Copy a setup snippet with one click

COSTS AT A GLANCE • Tokens and estimated costs per key, provider and model • Daily chart, list of recent requests, CSV export • Input, output and cache tokens – including streaming • Bundled, editable price table • Estimated remaining balance per provider

BUDGETS AND LIMITS • Monthly budget per key in tokens or US dollars – with a hard stop • Notification at 80 % usage • Optional limit on requests per minute • Optional Touch ID lock after restart, sleep and screen lock

MANY PROVIDERS • Built in: OpenAI, Anthropic, Google Gemini • Templates for xAI Grok, Mistral, DeepSeek, Qwen, Kimi, GLM, MiniMax, OpenRouter, Groq, Together AI, Fireworks, Cerebras and Perplexity • Anthropic-compatible endpoints to use Claude Code with other models • Add your own OpenAI- or Anthropic-compatible providers

ONLY ON YOUR MAC • The proxy listens on 127.0.0.1 only – unreachable from other devices • No account, no cloud, no telemetry • No prompts or responses stored – only time, model, status and token counts • Requests are not modified, no translation between providers

You need your own API key from at least one provider. Keyward is not an AI service and does not sell tokens.

Available in English and German; the app follows your Mac's language.
