Azure Key Vault, without the portal: KeyVault Studio is the native client for Mac, iPhone and iPad. Your secrets, keys and certificates are well protected in Azure. Managing them just takes too many clicks in the portal. KeyVault Studio turns that into a real Apple app: fast, focused and secured with Face ID / Touch ID. Want to look around first? Demo mode opens the complete app with sample data, no Azure account needed. SECRETS āø Create, view, update and delete, every value behind Face ID / Touch ID āø Full version history with side-by-side comparison āø Content types for JSON, XML, connection strings and API keys āø The app warns before anything expires, with thresholds you choose āø Copied values clear themselves from the clipboard KEYS āø Create RSA, EC and HSM-backed keys āø Crypto Playground: encrypt, decrypt, sign, verify, wrap, unwrap āø Rotation policies and one-tap rotation āø Import from JSON Web Key CERTIFICATES āø Issue self-signed and CA-signed certificates āø Import PFX/P12 and PEM, export the public certificate or the private key āø Manage policies, issuers, contacts and pending operations NETWORKING āø Configure the vault firewall, VNet rules and private endpoints āø Manage private DNS zones, record sets and VNet links āø Approve or reject private endpoint connections VAULTS āø Find vaults across all your Subscriptions in seconds āø Create a new vault with a guided wizard āø Backup and restore, AES-GCM encrypted if you want āø Recover or purge soft-deleted vaults and items AI ASSISTANT āø Ask questions about your own infrastructure: what expires soon, what is disabled āø Runs fully on device if you want: Apple Intelligence or Gemma, no cloud required āø Or bring your own key: Claude, OpenAI, Gemini, plus Ollama on your own network āø Naming suggestions per Cloud Adoption Framework, subnet and address space planning āø The assistant sees names and metadata, never secret values āø A visible token budget keeps API costs under control BUILT FOR APPLE PLATFORMS āø Mac, iPhone and iPad with the same feature set, tuned per size class āø Lightning-fast search across every vault and item, right on the device āø Several accounts side by side: Azure Commercial, US Government and China clouds āø No middleman servers: the app talks directly to Azure with your Microsoft Entra ID sign-in Bring your own app registration or use the built-in one.

Murmur BLE Shell

murmur turns your phone into a remote control for a Raspberry Pi ā no Wi-Fi, no network setup, no port forwarding. Just Bluetooth Low Energy (BLE), directly between your phone and the Pi. HOW IT WORKS Install the open-source murmur daemon on any Raspberry Pi running Linux, pair your phone with it over Bluetooth, and you get: ⢠Shell mode ā a real interactive terminal on the Pi, right from your phone. ⢠Agent mode ā describe what you want in plain English ("what's eating my disk space?", "set up a static IP") and an AI agent plans and runs the shell commands for you, showing every command and its output as it goes. BRING YOUR OWN API KEY Agent mode is powered by your own Anthropic Claude, OpenAI, or Google Gemini API key ā entered once in Settings, stored only in your phone's secure keychain. murmur has no backend server and no account system. The only network calls it makes are the LLM requests you trigger yourself, using your own key. WORKS OFFLINE ON THE PI SIDE The Raspberry Pi never needs an internet connection. It just needs Bluetooth and the murmur daemon running. Good for headless boxes, home labs, and devices you'd rather not put on a network at all. PRIVACY BY DESIGN Everything murmur stores ā the Bluetooth pairing key, your API key, an optional per-device sudo password, and saved agent conversations ā stays on your phone in the OS-level secure store. One tap in Settings wipes it all. OPEN SOURCE Both the daemon and the app are open source: github.com/nekonihq/murmur
