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

About

Promptoll

Features
Read full description

Promptoll is the AI gateway for developers who use more than one model. Connect once and reach every major LLM — GPT-5.5, Claude, Gemini, DeepSeek and more — through a single OpenAI-compatible API. No new SDKs, no rewrites: point your existing OpenAI client at Promptoll and switch models with a single line. WHY PROMPTOLL • One API, every model. Drop-in OpenAI compatibility means your existing code just works. • One key for everything. Generate an API key and call any model — no separate accounts, no scattered billing. • Pay as you go. Top up a balance and pay only for what you use. No subscriptions, no minimums. • Full cost transparency. Every request is logged with model, token count, latency and exact spend. • Smart routing. Optionally let the gateway auto-route to the cheapest equivalent model and cut your bill. IN THE APP • Dashboard — your balance, request volume, token usage and spend at a glance. • Chat — talk to any model from your phone and switch instantly with the model picker. • API Keys — create, name and revoke keys in seconds. • Logs — inspect every request with a full model, latency and cost breakdown. • Settings — manage your account, language and routing preferences. BUILT FOR DEVELOPERS Promptoll speaks the OpenAI Chat Completions format, so it works out of the box with the OpenAI SDK, the Vercel AI SDK, LangChain and any OpenAI-compatible client. Use the same base URL and key across web, mobile and server. Start free, add credit when you need it, and keep every token accounted for.
