What you get

Keep your AI coding sessions running while you step away.

You can leave a long Claude Code or Codex refactor running overnight without your Mac falling asleep mid-session. BlackFlare keeps it awake while the session is active, even with the lid closed and no external display connected. When the session ends, your Mac can sleep normally again.

You don’t have to keep checking the terminal to know whether work has finished or needs your input. You can receive alerts on your Mac, through Telegram, or in Slack, including for agents running inside VS Code or JetBrains. You can also check per-model usage from the menu bar and set warning thresholds before you reach your plan’s limits.

For your next session, you can choose the model, permission mode, effort level, and thinking mode without remembering command-line flags. BlackFlare backs up the tool’s configuration before applying your choices. You don’t need a BlackFlare account, and the app runs locally without analytics or tracking.

  • Leave long sessions running

    You can close your Mac’s lid during an active session without sleep interrupting the work.

  • Know when you're needed

    You get completion and input alerts on your Mac, Telegram, or Slack instead of repeatedly checking your session.

  • Anticipate usage limits

    You can see per-model Claude and Codex usage and receive warnings at thresholds you choose.

  • Change your next session

    You can select model and execution defaults from the menu bar without looking up command-line flags.

Best for

  • You leave Claude Code or Codex running on overnight refactors
  • You want session alerts while away from your Mac
  • You regularly check AI usage and adjust session defaults

Skip it if

You don’t need it if you don’t use Claude Code or Codex.
