Read full descriptionHide full description
Byoky is a wallet for your AI API keys. Keep your OpenAI, Anthropic, Gemini and other AI keys in one encrypted wallet on your iPhone or iPad. Apps connect to the wallet, you approve, and Byoky makes the API calls for them. The app never sees your key. WORKS IN SAFARI The Byoky Safari extension brings the wallet to Safari. Add keys in its popup, and websites that support Byoky can use them, just like the desktop extension. BUILT-IN BROWSER Open any web app inside Byoky by its address. It connects to your wallet automatically, with no extension needed. ONE WALLET, EVERY PROVIDER Anthropic (API keys and Claude setup tokens), OpenAI, Google Gemini, Mistral, Cohere, xAI, DeepSeek, Perplexity, Groq, Together AI, Fireworks, OpenRouter, Azure OpenAI and custom endpoints. YOU STAY IN CONTROL • Approve every app before it connects. • See every request and token count. • Set allowances, and revoke access any time. • Groups and cross-provider routing: move an app from Claude to GPT without the app changing a line. NO SERVERS No account. No cloud. No tracking. Keys are encrypted and stored in the iOS Keychain. Requests go straight from your phone to the provider. Move keys between devices with password-protected .byoky backup files. OPEN SOURCE MIT-licensed on GitHub: github.com/MichaelLod/byoky
