Doom Coder vs AssertKit

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

AssertKit puts three developer tools behind one account. MAIL SHIELD — Shielded inboxes & aliases Pick any name @assertkit.com and a disposable inbox appears the moment the first message lands. One-time passcodes and magic links are detected and surfaced for a single tap to copy, then cleared. Star the mail you want to keep, search across addresses, and export when you need to. ASK AEGIS — Chat your code review Ask plain-language questions about your pull-request security scans: what got flagged, how severe it is, and how to fix it. Aegis answers from your real findings — no dashboards to dig through. ASK AUDIT — Ask about your project Get answers about project status, blockers, and signals across your sources and timelines, with charts when a picture says it faster. WHY ASSERTKIT • Sign in with Apple or Google — no password to manage • Mail Shield is free • Honest, private by design: your inboxes and conversations are yours • One workspace on web and mobile Mail Shield is free to use. AI features (Ask Aegis and Ask Audit) run on credits — new accounts start with free credits, and you can top up any time. Privacy: https://assertkit.com/privacy Terms: https://assertkit.com/terms
