AgentNotch
Watch Claude Code and Codex burn tokens in real time from your Mac's notch.
AgentNotch is a thoughtfully scoped, free utility that nails the niche of at-a-glance AI cost monitoring on macOS. If you're all-in on Claude Code and Codex, it's a smart install—no screen space, no setup hassle, just live token and cost visibility. It's early-stage and macOS-only, so Linux users or teams needing deep traces should look elsewhere, but for the price (zero), it's a win.

About AgentNotch
AgentNotch is a free, MIT-licensed macOS menu bar app that turns your Mac's notch into a live observability feed for AI coding assistants. Built for developers who live in Claude Code or OpenAI Codex, it sits discreetly in the notch (or menu bar on non-notch Macs) and streams telemetry from your local sessions, showing every tool call—file reads, code edits, shell commands—as it happens. No more tabbing out to a terminal to see if the agent is stuck or just slow; a glance tells you what the assistant is doing and how much it's costing you. The app ingests OTLP/HTTP telemetry on port 4318, decoding logs and metrics from your assistants. It tracks input and output tokens with real-time cost estimates, so you can spot runaway spend before it shows up on the API bill. Color-coded indicators—orange for Claude, blue for Codex, light blue for unknown sources—let you identify which assistant is active at a glance, and completion notifications fire when a task wraps up, so you're not left wondering if it's still thinking. Setup is direct: for Claude Code, you export an OTEL endpoint pointing to localhost:4318; for Codex CLI v0.79+, you add an [otel] section to ~/.codex/config.toml and set trace_exporter to "none" because AgentNotch doesn't decode traces. Installation is a single Homebrew cask command or a manual download from Releases. It requires macOS 14.0 (Sonoma) or later and runs 100% locally—no data ever leaves your machine. Where AgentNotch shines is passive, glanceable observability. It's not a full log viewer or trace analyzer; it's a focused cost and activity guardrail for your existing workflow. If you use both Claude Code and Codex on a modern Mac, it's a zero-cost add-on. If you're on Windows or Linux, need deep trace-level analytics, or work with other assistants, you'll want a more general tool like Langfuse or an OpenTelemetry dashboard.
Behind the Verdict
AgentNotch earns its place by doing one thing well: giving you real-time visibility into what Claude Code and Codex are doing without forcing you to leave your editor. Its notch placement is a clever use of otherwise dead screen space on modern MacBook Pros, and the color-coded indicators let you know at a glance which assistant is active. The token and cost tracking is a genuine value—there's nothing worse than a runaway agent racking up API charges while you think it's making progress. Completion notifications are the cherry on top. On the downside, it's macOS-only, so Linux and Windows developers are out of luck. It only supports Claude Code and OpenAI Codex, and it decodes OTLP logs and metrics but not traces, so you won't get detailed step-by-step execution paths. The app is also early-stage, so you might hit bugs, and documentation is thin—you'll be reading the README and figuring things out. There's no team support, no SSO, no SLAs; it's a solo, local tool. Where AgentNotch fits best: you're a solo developer or small team on macOS who uses Claude Code or Codex regularly and wants to keep an eye on spend and activity. It's especially useful if you juggle multiple agents and need to know which one is chewing through tokens. If you need cross-platform support or deep tracing, Langfuse or an OpenTelemetry dashboard is a better fit. But as a free, zero-effort add-on, it's hard to beat.

Real-world workflow fit
Concrete scenarios for the personas AgentNotch actually fits — and what changes day-one when you adopt it.
You're running a long Claude Code session to refactor a module. You want to know if it's making progress and how many tokens it's burning.
Outcome: AgentNotch shows each tool call in the notch — you see file reads and edits as they happen, and the token counter updates in real time. The cost estimate rises steadily, but you're prepared for it. When the task completes, you get a notification without tabbing back to the terminal.
You alternate between Claude Code for one repo and Codex for another, and you lose track of which agent is active and how much it's spending.
Outcome: The color-coded indicators — orange for Claude, blue for Codex — tell you at a glance which assistant is running. You can filter by source, so you see only Claude's activity when you're working on that project. The cost tracking helps you allocate spend per agent.
You run Claude Code occasionally but worry about unexpected API charges when you leave a task running unattended.
Outcome: AgentNotch's real-time cost estimates let you spot a runaway spend before it hits your bill. You can glance at the notch to see if the agent is stuck in a loop, and you can interrupt it early. The completion notification tells you when it's done, so you're not leaving it running longer than needed.
