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

a+Terminal is a privacy-first SSH terminal for working on your own machines from your iPhone — built around tmux and CLI AI coding agents. It's agent-agnostic: run any CLI coding agent, with plug-and-play profiles you can extend yourself. SCROLLING THAT ACTUALLY WORKS Swipes become real mouse-wheel events, so tmux and your agent's output scroll natively, with momentum — no more fighting copy-mode. SPEAK YOUR PROMPTS Push-to-talk dictation inserts straight into the terminal. Recognition runs entirely on your iPhone; audio never leaves the device. NEVER LOSE YOUR SESSION Live Activities and the Dynamic Island show your active sessions at a glance. Tap to jump back in — a+Terminal reconnects and re-attaches your session multiplexer (tmux, zellij, and more) automatically. PREVIEW YOUR DEV SERVER Start a dev server on the machine you're connected to and a+Terminal spots the port — from the URL your framework prints, or from the machine's own listener table. Tap it and the page opens over the SSH connection you already have. It renders in a viewer built for exactly one thing: the single port you forwarded. Every other address is refused, nothing it loads is kept, and it is not a web browser. Reload with a tap, and switch between the mobile and desktop layout to check both. MONITOR YOUR MAC Add a Monitor (VNC) session to watch your own computer's screen sharing right from your phone. Sign in with your macOS account and you land straight on the desktop; pinch to zoom and pan. Pop the screen out into a floating Picture-in-Picture window to keep an eye on it while you use other apps. Turn on Control to tap, drag, and type — enough to unlock a locked Mac and take over. It stays view-only until you do, and it connects only to the machine you enter. (Beta.) ZERO DATA COLLECTION No analytics, no accounts, no crash SDKs, no servers of ours. The App Privacy label says "Data Not Collected" because there is nothing to collect it with. The only network traffic is your own connections to machines you configure. SUPPORT THE APP An optional tip jar lets you support a+Terminal's development. Tips are one-time and unlock nothing — every feature is always available. • ed25519 keys generated on-device and kept in this device's Keychain, never in backups; they leave it only if you reveal, copy or export them • Password authentication option, stored in the Keychain only • Trust-on-first-use host key pinning with hard mismatch failures • Sticky Ctrl and C-b (tmux prefix) keys, Esc/Tab/arrows accessory bar • Attach an image or file from your phone over the existing SSH connection • Plug-and-play agent & multiplexer profiles — any CLI agent, tmux, zellij, screen — or define your own, no update required • Multiple simultaneous sessions with server groups • Preview a dev server running on the far end, over the SSH connection you already have — port detection and a single-port viewer • Monitor (VNC): view-only screen sharing for your own Mac, with a floating Picture-in-Picture window and optional touch & keyboard control (beta) • Light, dark, and follow-system themes Privacy Policy: https://aaroncx.github.io/a-plus-terminal/privacy
