What Obzr does

Mac monitoring

CPU and GPU load, memory, disk, network and temperatures, each as its own menu bar item if you like. Click for charts, the busiest processes and explanations like “Spotlight is indexing your disk”.

Claude and Codex limits

How much of your five-hour and weekly limits you've used and when they reset. For Claude also per-model limits and your plan. What you use in the desktop app counts too.

Your AI agents

A widget with your Claude Code and Codex sessions: what's running, what's waiting for your answer and what's done. Click to open that exact session.

Website monitoring

Availability, response time, SSL certificate expiry and, if you want, a text that must be on the page. Our server does the checking, so it keeps going while your Mac sleeps, and outages reach you on the Mac and in Telegram.

Desktop widgets

AI limits, sessions and system status as desktop widgets, in light and dark mode.

Help from AI

When your Mac is slow, Obzr writes down what it sees and hands it to Claude Code or Codex. They look for the cause first and ask before changing anything.

What Obzr knows about you

  • Without an account, nothing. Mac monitoring, limits and widgets run only on your Mac. No analytics, no ads.
  • It stays away from your Claude sign-in. Claude Code reports its own limits; Obzr reads no tokens.
  • An account only for websites. You create it with Apple, no password is ever stored and you can hide your email. The server runs in the EU.
  • Updates you can trust. Every version is signed, notarized by Apple and checked again by Obzr before it installs.

What it costs

Everything that runs on your Mac is free and will stay free. You'll only pay for server-side website monitoring, and only if you want more sites or more frequent checks.

    Obzr is now signed and notarized by Apple, so it opens on any Mac without warnings.

Questions

What do I need for Claude limits?

Claude Code (the CLI), installed and signed in once. You don't have to use it; Obzr asks it for your usage on its own. What you use in the Claude desktop app counts too.

Does Obzr run on an Intel Mac?

Not yet. It reads temperatures and frequencies from Apple silicon sensors, so it needs a Mac with M1 or later and macOS 15.

Do I need an account?

Only if you want your websites monitored, because our server does that. Sign in with Apple is all it takes, no new password. Everything else works without an account and without talking to our server.

How does Obzr update?

By itself. Once an hour it looks for a new version, shows you what's new and, once you confirm, installs it and restarts.

Will there be a Windows or iPhone version?

An iPhone app with website outage alerts is on the way; Windows is under consideration. If you'd use them, let me know.

Why Obzr exists

It started as one widget for limits

I started writing Obzr for myself. I code with Claude Code and Codex every day, and every so often a limit ran out in the middle of a task without any warning. So I built a small widget that showed how much was left.

Then I wanted to see what was slowing my Mac down, so system metrics came next. Then an overview of agents, once I had several running at once. I watched my websites (and still do) in Better Stack, but I wanted them in the same place as everything else. That's how the widget turned into a horizon: one place I look when I want to know everything's fine.
