Adrafinil

Adrafinil keeps a Mac awake through a closed lid while a coding agent works, then releases the hold when the turn ends. Hooks track active work across agents; a thermal cutout and automatic release of abandoned holds limit unattended runs.

Highlights

• Keep a closed-lid Mac running for the duration of agent work.
• Track overlapping agents independently; sleep resumes after the last hold ends.
• Limit unattended holds with a thermal cutout and abandoned-session cleanup.

Full feature list

• Hooks for Claude Code, Codex, Cursor, Gemini CLI, Devin, Aider, Hermes, OpenCode, Cline, and Pi.
• Per-session acquire/release, timed holds, and manual Let it sleep control.
