About AgentNotch
AgentNotch is a lightweight macOS menu bar app that lives in your Mac's notch, offering real-time visibility into your AI coding assistants. It hooks into telemetry from Claude Code and OpenAI Codex, displaying tool calls, token usage, and cost estimates in a compact, always-visible interface — no more switching windows to check what your agent is doing. Designed for developers who use AI assistants intensively, it supports real-time tool tracking, source-aware colored indicators (orange for Claude, blue for Codex), completion notifications, and configurable display options. The app runs 100% locally, is open-source under MIT, and installs easily via Homebrew. AgentNotch stands apart by making agent observability glanceable and non-intrusive, whereas alternatives like full-screen log viewers or terminal-based monitors require more attention and screen space.
Behind the Verdict
AgentNotch fills a niche that's surprisingly underserved: real-time, glanceable AI assistant telemetry without leaving your editor. If you're a heavy Claude Code or Codex user on a modern Mac, this app feels like a missing piece of your workflow — it turns abstract API calls into a live dashboard that sits unobtrusively in your notch. We'd reach for this when debugging runaway agent loops or watching costs tick up mid-session. The MIT open-source license and 100% local processing are reassuring for privacy-conscious developers, and the Homebrew cask makes setup trivial. However, it's macOS-only (Sonoma+), so Linux and Windows devs are out of luck. It also only supports Claude Code and Codex — if you use other assistants like continues.dev or aider, it won't show anything. The notch-based UI is clever but less effective on non-notch Macs (falls back to menu bar). Compared to alternatives like terminal-based monitors or full-screen dashboards, AgentNotch is far less distracting but also less data-rich — it shows the headline numbers and recent calls, not a deep history. For most daily use, that's enough. Where it bites: if you're on an older macOS or don't have a notch, the experience is merely okay. Also, there's no official roadmap for supporting more assistants, so future-proofing is uncertain. Still, at $0, it's hard to argue against trying it for a day.
