Insomnia prevents Windows from sleeping — automatically when AI coding tools are working, when specific apps are running, or manually on demand. No more broken sessions.
You're running Claude Code or Aider on a long task. You step away.
Your PC falls asleep, kills the process, and you come back to a broken session and lost work.
Setting your sleep timeout to "Never" works — but then your PC never sleeps when you actually want it to.
Insomnia fixes this. It stays awake only while something needs it, then gets out of the way.
For Claude Code, Insomnia hooks directly into the event system — awake while Claude is working, asleep the moment it stops. Precise to the second.
Add any app as a trigger. Insomnia auto-discovers every installed app on your system. When it's running, you stay awake. When it closes, you don't.
Need to stay awake right now? One switch. No timers, no fuss. Toggle it off when you're done.
A purple owl means awake. A grey owl means inactive. The hover tooltip tells you exactly why. Close the window — it keeps running.
Plain HTML, CSS, and JS. No React. No bundler. Zero external runtime dependencies. Installs in seconds and uses almost no resources.
Nothing leaves your machine. No telemetry, no accounts, no cloud. Settings are stored locally and that's it.
| Tool | Type | How it works |
|---|---|---|
| ✨ Claude Code | Smart | Hook-based — awake only while Claude is actively running tools. Idle = asleep. |
| ✏️ Cursor | Process | Awake while Cursor is open. |
| 🤖 Aider | Process | Awake while Aider is running. |
| 💻 OpenAI Codex CLI | Process | Awake while Codex CLI is running. |
| 🧠 Ollama | Process | Awake during local model inference. |
