ShieldNode

Read full description

ShieldNode is the secure vault and live control panel for every API key your AI agents touch. THE PROBLEM AI agents are powerful, and you give them your API keys to get real work done. But a misfired prompt, a bad tool call, or a runaway loop can drain your Stripe credits, hit your OpenAI rate limits, or post the wrong thing to your Slack. Once an agent has the key, you are trusting it with everything that key can do. THE FIX Your real upstream keys live in our encrypted vault, never in a prompt, never in a config file, never in your agent's context. Your agents only ever see virtual keys that route through our proxy. The proxy decrypts the real credential in memory at the exact moment the request needs to go out, and the value never gets returned to any caller. Every sensitive call can ask you first. DROP-IN AGENT SKILL The piece that makes the whole thing work for anyone using an AI assistant: a free, open-source ShieldNode skill that plugs straight into Claude, ChatGPT, Cursor, Codex, and any agent that can load instructions. One install and the agent learns to use virtual keys correctly, request the right approval duration, identify itself by name in your notifications, and back off cleanly when you decline. You do not have to teach your agent anything. The skill does it. PUSH APPROVAL The killer feature. When your AI agent tries to use a protected key, you get a time-sensitive push notification. Approve from the lockscreen, set a duration (5 minutes, 30 minutes, 2 hours, or custom), and the agent gets through for exactly that window. Decline, and the request dies on the spot. No app switch. No dashboard hunting. UNIVERSAL VAULT One app, every API. Stripe, GitHub, OpenAI, Anthropic, SendGrid, Slack, Notion, anything that takes a key. Add a new service in seconds with the in-app AI Configurator: point it at the docs, it auto-fills the auth scheme and base URL for you. FULL CONTROL Pause a key. Disable a service. Delete a virtual credential. Watch every call land in your live audit log with the method, path, status, latency, plus the agent name and decision when a request was gated by approval. EMERGENCY STOP One tap. Every key locks. Every agent freezes. No confirmation, no delay. The big red button you always wished you had. WHO IT IS FOR - Developers shipping autonomous agents and tired of waking up to surprise bills - Builders letting AI access production credentials and needing a human in the loop - Anyone who hands an API key to an AI agent securely SUBSCRIPTIONS Free plan: 2 services and 500 requests per month, no credit card required.

Privacy Policy: https://shieldnode.app/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Real keys stay encrypted in our vault. Virtual ones do the work. The skill teaches your agent. You stay in control.

Doom Coder sends a notification to your iPhone and iPad the moment your AI coding agents finish, fail, or stop to ask for approval — so you can start a long run, walk away, and trust your phone to call you back. It pairs with the free Doom Coder app for Mac, which watches your agents and keeps your Mac awake while they work. When an agent needs you, the alert reaches your phone in seconds. WORKS WITH YOUR AGENTS Doom Coder understands the events from Claude Code, Cursor, VS Code Copilot, Copilot CLI, Windsurf, Codex CLI, and opencode. You choose exactly which events alert you — completed, failed, waiting for approval, waiting for input — and mute the rest. USEFUL THE SECOND YOU OPEN IT No account. No sign-in. No Mac required to get started. • Prompts — A prompt refiner, not a chatbot. Type a rough request and get back a clean, structured prompt you can paste straight into your agent. Keep refining over follow-up turns, and pull from a built-in library of developer prompts grouped by Refactor, Tests, Debug, Review, Explain, Git, Docs, and Scaffold. • Notes — On-device notes with checklists, reminders, pinning, and search. Turn any note into a prompt with one tap. • Dashboard — Once you pair a Mac, see every agent's live status and drive the Mac's keep-awake controls from your phone. PRIVATE BY DESIGN No servers. No analytics. No tracking. Everything you write stays on your device. When you pair a Mac, sync happens only through your own private iCloud account using Apple CloudKit — your data is never visible to us or anyone else. ON-DEVICE OR BRING YOUR OWN KEY The prompt refiner runs on Apple Intelligence entirely on your device, so nothing leaves your phone. Prefer your own model? Add an OpenAI or Anthropic API key — it is stored only in your device's Keychain, and only the text you choose to enhance is ever sent. Enhancing is always optional. BUILT FOR iOS 26 AND iPadOS 26 A native interface with the system Liquid Glass design, a macOS-style sidebar on iPad, and time-sensitive notifications that reach you even through Focus. Doom Coder is open source. Source, documentation, and support: github.com/katipally/Doom-Coder
