Show HN: Modafinil — macOS Menu Bar App Keeps AI Agents Running with Laptop Lid Closed — 14 Points, 24 Comments

GitHub / Hacker News·low signal

A new macOS menu bar app prevents MacBook sleep when the lid is closed while letting the display turn off normally, purpose-built for the agentic coding workflow where work continues after you stop typing. Solves the specific problem that Codex, Claude Code, Cursor agents, and local browser agents may still be reading files, running tests, or calling tools when the user walks away. At 14 points but 24 comments (nearly 2x the engagement ratio), it's hitting a nerve with practitioners running long agent sessions.
