Session-aware notifications
BlackFlare watches Claude Code and Codex sessions in the terminal, VS Code, and JetBrains, and sends a notification when a turn finishes or waits for input.
BlackFlare
ПодтвердитьBlackFlare is a macOS menu bar app for Claude Code and Codex that keeps sessions awake, sends finish or input-needed alerts, shows usage, and forwards notifications to Telegram or Slack.
What BlackFlare does
BlackFlare is a macOS menu bar app for Claude Code and Codex that helps long-running agent sessions finish without interruption. It keeps your Mac awake while a session is active, then restores normal sleep behavior when the work is done.
It also notifies you when a session finishes or needs input, whether you are using the CLI, VS Code, or JetBrains. From the menu bar, you can adjust default model and permission settings, track usage, and forward alerts to Telegram or Slack if you want updates away from your desk.
Features
Keep-awake during active runs
The app can hold a power assertion while a session is running, which keeps the Mac from idling to sleep during long tasks. Sleep returns to normal automatically when the session ends.
Telegram and Slack forwarding
Notifications can stay on the Mac or be forwarded to Telegram or Slack. An "only when away" mode reduces duplicate alerts when you are already at your desk.
Default switching from the menu bar
From the menu bar, you can set your default model, permission mode, effort level, and thinking mode for the next session. BlackFlare applies those settings by editing each tool's own config file.
Usage tracking and thresholds
Usage tracking shows Claude and Codex plan usage in the menu and menu bar icon, with separate bars per model and alerts when a threshold is crossed.
Private, local operation
The app runs on-device and asks for read-only Keychain access to your Claude token so it can display exact usage.
Common ways people use BlackFlare
Running long CLI sessions
Start a long refactor, test run, or other agent task and let BlackFlare keep the Mac awake so the session does not stall midway through sleep.
IDE-based agent workflows
Work in VS Code or JetBrains and get a banner when Claude Code or Codex finishes or needs input, so you can step back in at the right time.
Remote and team notifications
Forward alerts to Telegram or Slack when you are away from your desk, and use the away-only mode to avoid duplicate notifications while you are nearby.
Fast session setup
Set model, permission, effort, and thinking defaults from the menu bar before starting a session, instead of editing config files or remembering flags.
Usage monitoring
Watch Claude and Codex usage side by side in the menu bar and set a threshold alert before you cross your plan limits.
