  • Vite
  • Hono
  • Storybook
  • Bun
  • Deno
  • Astro

Know what every
agent is doing.

Every Claude Code, Codex and Cursor session, named by its task. Catch the one waiting on you before it sits idle, and see your limits before you hit them.

  • Named by the task

    Not by a process id or a terminal tab.

  • Waiting on you comes first

    A session that needs an answer jumps to the top.

  • Limits before you hit them

    Five-hour and weekly usage, next to the work.

When a session ends, clear it in one click.

Agents leave servers running, ports taken and gigabytes of worktrees and caches behind. Mizu finds what a finished session left and gives the space back.

  • Only what that session started

    Your own servers and files stay put.

  • See it before it goes

    Every item is listed, so nothing goes by surprise.

  • Uncommitted work is kept

    A worktree with changes is never removed.

Build the panel
you actually need.

Servers, agents, workspaces and Claude limits, as widgets in three sizes. Keep what you check every day, drop the rest.

Drop widgets side by side to group them.

The little things, done right.

  • Every project, one shortcut away.

    Press ⌥ Space to open, restart or stop anything you’re running. Your hands never leave the keyboard.

  • Every server gets a real name.

    landing.localhost instead of :3000. No more guessing which port is which, or which tab is which app.

  • Catches what you’d miss.

    A server left running, a usage limit almost spent. You hear about it once, quietly, while there’s still time to act.

  • Private by design.

    No account, no analytics, nothing synced. Mizu only checks your licence and looks for updates, and reads claude.ai if you connect it.

Early bird: $10 off every licence

Pay once. Keep it.

No subscription. Every licence has every feature and a year of updates, and Mizu keeps working for good after that.

Does macOS let Mizu open?
Yes. Mizu is sold directly, not through the App Store, but it’s signed with an Apple Developer ID and notarized by Apple. The first time you open it, macOS asks whether to open an app downloaded from the internet: click Open, and that’s it.
What happens after the year of updates?
Mizu keeps working, for good, and you keep every version released in your year. Mizu stops updating itself then; renew at half price whenever you want the newer ones.
Can I move Mizu to a new Mac?
Yes. Free the old Mac in Settings › Licence, then activate on the new one. If the old Mac is gone, free it from the Licence page with your key and email.
Does Mizu send anything about me?
Only what a licence needs: your key, a hashed id for the Mac and its kind, like “MacBook Pro”, when you activate and about once a week after. Every few hours Mizu also asks usemizu.com for updates, sending nothing but its version. If you connect Claude, Mizu reads your usage limits from claude.ai, never your chats. No analytics, no crash reports, nothing about your projects.
What if Mizu isn’t for me?
Ask for a full refund within 14 days, no reason needed. Write to volkan@uikielle.com.
