Nibi
Arcade version Download

For Windows 11 and 10

Once upon a desktop, there lived a squishy little blob called Nibi.

A small friend on your desktop that watches your AI agents.

Nibi shows what Claude Code, Codex, Antigravity, VS Code and ChatGPT are doing, right now, in one soft blob. When an agent needs you, Nibi rings the bell. Everything stays on your PC.

Download for Windows See what it does

Version 1.5.0 · Per-user install, no admin · No account, no telemetry

The real Nibi playing: it waves, juggles three balls, sends a heart, blows bubbles and spins. The real Nibi juggling three balls.
The real thing. Drawn by Nibi's own renderer: a wave, a juggle, a heart, bubbles and a spin, while your agents are quiet.

Working three agents at work

Click Nibi to tickle it. Poke the little ones in its Flock, too.

How it works

Three steps, then Nibi does the watching.

  1. Install it

    Run the per-user installer. No admin prompt, no account. Nibi lives in %LOCALAPPDATA%\Nibi.

  2. Connect your agents

    In Settings → Agents, click Install hooks for Claude Code, Codex, Antigravity or Copilot. Each settings file is backed up first. Then switch on the services you use.

  3. Nibi watches

    It stands on the title bar of the window you are using, hatches a sprite for every live session, and rings the bell when one needs you.

Chapter one · What Nibi watches

Every agent, every build, one glance.

Each running session hatches a small sprite that floats around Nibi: the Flock. Three sprites means three agents at work. A sprite with a ring of amber is waiting for you.

Agents and editors

  • Claude CodeCLI and the desktop Code tab, through its official hooks. Thinking, working, needs you, done, error.
  • CodexCLI and app hooks, including permission requests.
  • AntigravityWorking and quiet, inferred from its conversation files.inferred
  • VS CodeCopilot agent hooks plus a small extension for tasks, tests and debug runs.
  • ChatGPTIn use and reply ready, from its window and notifications.inferred

Services

  • GitHub CIWorkflow runs passing or failing, and reviews waiting on you.
  • VercelDeploys building, ready or failed. Your token lives in Windows Credential Manager.
  • DevPulseYour sites up or down. Only critical incidents turn Nibi red.
  • CalendarA heads-up before your next meeting, from an iCal link.
  • MusicWhat is playing, so Nibi can sway along.

A solid sprite means a verified event from a hook. A dashed one means Nibi is inferring. Silence never means done: a session that goes quiet becomes “unknown”, not “finished”.

The Connections page of the Nibi panel, grouping agents and editors, services, and keys, each with a status dot and when it last sent an event.
Connections: what is set up, verified or inferred, and when each one last spoke.

Chapter two · Meet the moods

One look tells you how things are going.

The most urgent session sets Nibi's mood. Hover or tap a sticker to wake it up.

Nibi also puts on headphones when music is playing, and a little hat before your next meeting.

Chapter three · The Approval Bell

Never leave an agent waiting.

Agents stop and wait for permission all the time, often in a window you are not looking at. Nibi notices within a second.

  1. It hears the request. A permission prompt from Claude, Codex or Copilot turns Nibi amber.
  2. It walks over and taps. Nibi hops to the edge of that terminal or editor and knocks on it.
  3. One click takes you there. Click Nibi and the exact window comes to the front. You answer in the agent, as usual.

Nibi never answers an agent's permission prompt for you. That decision is always yours.

All quiet. Press the button to make an agent ask.

The Now page of the Nibi panel. At the top, an amber card says Claude is waiting in shop, with an Open button. Below, sessions are grouped by Claude, Codex, Antigravity and VS Code with state chips.
Now: who needs you first, then every live session by tool.

Chapter four · Rules and approvals

Small helpful rules. You stay in charge.

Rules are simple “when this happens, do that” cards, stored as data, never as code. What a rule may do is fixed by Nibi, not by the rule.

Runs on its own

Safe actions

Say something, react, focus an agent's window, open a link from a trusted service. Once you switch the rule on, it just happens.

Asks you first

Anything else

Re-running a failed CI job and anything that changes the outside world waits for your Yes, every time. No answer in 15 minutes means no.

Never

Off limits

Shell commands, deleting files, reading passwords, or anything built from the text of an event. Nibi cannot do these at all.

The Rules and activity page of the Nibi panel, listing rule switches and an activity log with entries marked Queued, Blocked, Done and Failed, each with its reason.
Rules and activity: every attempt, with its outcome and reason.

Everything is audited

  • Every action Nibi tries is written to an append-only log: done, blocked, queued, approved, denied or failed, and why.
  • The same event twice never runs an action twice.
  • One Pause switch, in the tray and on right-click, stops every action.
  • Focus mode keeps Nibi quiet except for approvals and errors.

Chapter five · A day in Nibi's life

From the first prompt to lights out.

An example day. Pick a moment, or let the day play.

08:55

Coffee time. Nothing is running yet, so Nibi just breathes.

Chapter six · Your day

A recap at the end of the day.

How many prompts you ran, what finished, how often an agent waited for you, which builds and CI runs passed. Ask Nibi for the recap and it says it in a bubble.

Talk level is yours: Quiet (only approvals, failures and the recap), or Playful.

The Today page of the Nibi panel with tiles for prompts, finished, approvals and errors, pass and fail bars for builds and CI runs, a bar of events by source, and a timeline.
Today: the numbers, by source, and a timeline.

Chapter seven · Privacy

Everything stays on your PC.

Nibi has no servers, no accounts and no telemetry. It listens only on your own computer (127.0.0.1), behind a random token. Once a day it asks GitHub whether a newer version exists (you can switch that off in Settings); nothing about you is sent.

Never stored

  • Your prompts or the agent's replies
  • Tool inputs: commands, file contents, code, diffs
  • Window titles
  • Secrets. A token you add (for example Vercel) is kept in Windows Credential Manager, never in a file.

What is stored, and for how long

  • Event historyWhich tool, project folder name, state, tool name and time. Kept 14 days (you can change it), then deleted.
  • Audit logRule, action, outcome and reason. Kept 90 days.
  • Debug logThe same minimal events, capped at about 5 MB.
  • Settings and rulesUntil you change or remove them.

All of it lives in %APPDATA%\Nibi. Delete the folder and it is gone.

This website has no analytics, no cookies and no third-party scripts. The full privacy page covers what optional features send and how to delete your data.

Chapter eight · For your agents

Let Claude ask Nibi how things are going.

Nibi includes a read-only MCP server. Agents can ask who is waiting for you, how today went, and which approvals are pending. They cannot change anything, and they can never answer an approval.

claude mcp add nibi -- "%LOCALAPPDATA%\Nibi\bin\nibi-hook.exe" mcp

For Codex, add the same command to config.toml under [mcp_servers.nibi]. Tools: list_sessions, get_day_summary, get_pending_approvals.

Want agents to make Nibi speak? Switch on Let agents make Nibi speak and react in Settings → MCP. It is off by default, allows at most one line every 10 seconds (up to 120 characters), and each one is logged without the words.

Chapter ten · Install and uninstall

Easy to add. Clean to remove.

Nibi installs like any small Windows app and leaves nothing behind when you remove it.

Installing

  • Installs for you only, in %LOCALAPPDATA%\Nibi. No admin prompt.
  • Does not start with Windows unless you switch that on.
  • Agent hooks are only added when you click Install hooks. Each settings file is backed up first, and other tools' hooks are left alone.

This build is not code-signed yet. Windows SmartScreen may say it protected your PC. Choose More info, then Run anyway.

Uninstalling

  • Remove Nibi from Settings → Apps, like any other app.
  • The uninstaller removes every agent hook Nibi added (Claude Code, Codex, Antigravity, Copilot) before it deletes any files.
  • Your history is kept unless you tick Delete the application data, so a reinstall picks up where you left off.

What you need

  • Windows 11 or 10, 64-bit (x64).
  • Microsoft Edge WebView2 for the panel. It comes with Windows 11 and most up-to-date Windows 10 PCs.
  • Your agents, any of: Claude Code, Codex, Antigravity, VS Code with Copilot, ChatGPT.
  • Optional: the GitHub CLI (gh) for CI and reviews, a Vercel token, a DevPulse site, an iCal link.

Questions

Things people ask.

Is it free?

Yes. You can download it and use it on your own computers for personal or work use, free of charge. It is not open source; see the licence.

Does Nibi send my data anywhere?

No. Nibi has no servers, no accounts and no telemetry, and it never stores your prompts, the agents' replies or tool inputs. The only network calls are the services you switch on talking to their own servers (GitHub through gh, Vercel, your DevPulse, your calendar feed), AI talk if you turn it on, and a daily check of GitHub for a newer version, which you can turn off. The privacy page has the details.

Why does Windows warn me when I run the installer?

This build is not code-signed yet, so SmartScreen does not know it. Choose More info, then Run anyway. Updates are still safe: each one is signed with Nibi's own key and checked before it is installed.

Which agents work with it?

Claude Code and Codex through their hooks, VS Code with Copilot agent hooks and a small extension, and Antigravity and ChatGPT, which Nibi infers and draws dashed. It also follows GitHub CI and reviews, Vercel, DevPulse, your calendar and music.

Will it slow my PC down?

Measured on the developer's PC: asleep with the panel closed, Nibi uses about 1% of one CPU core; busy and animating at 60 frames a second, about 3 to 5%. The panel only exists while it is open.

Can Nibi talk with AI, using my own key or a local model?

Yes, if you want it to. AI talk is optional and off by default. Switch it on in Settings and pick a provider with your own API key, or a local model on your PC. Your key is kept in Windows Credential Manager, never in a file. Nibi sends only short event summaries to the provider you picked, never your prompts, code or the agents' replies.

Give Nibi a free brain

Nibi can think with a small model that runs on your own PC: free, offline, no account and no key, and nothing leaves your computer. In Settings → Give life to Nibi, press Set up in one click: Nibi checks your PC and suggests the best free option, downloads its brain if needed (about 490 MB, or 390 MB on PCs with less than 4 GB of memory) and says hello. Downloads are checked against pinned checksums and resume if they stop. The brain wakes up when Nibi has something to say and naps after 5 minutes. From a terminal: nibi-hook brain download qwen2.5-0.5b, then nibi-hook brain use qwen2.5-0.5b.

How do I uninstall it?

Settings → Apps → Nibi → Uninstall, or irm https://niranjand.in/nibi/uninstall.ps1 | iex, or scoop uninstall nibi if you used Scoop. The uninstaller removes every agent hook Nibi added before it deletes any files. Your history is kept unless you tick Delete the application data (or delete %APPDATA%\Nibi).

How do I report a bug?

Use Send report in Nibi: it opens a GitHub issue in your browser with the details filled in, and nothing is posted until you have read it and pressed Submit. You can also open an issue yourself at github.com/Niranjan266/nibi-releases.

Does it need admin rights?

No. It installs for you only, in %LOCALAPPDATA%\Nibi, without an admin prompt. The one-command install and Scoop do the same.

How does it update?

Once a day Nibi asks GitHub whether a newer version exists. It installs one only when you press Install, and every update is signature-checked. You can switch the check off in Settings.

The end. Or rather, the beginning.
