Glass Power Tools

The machines you work on, in one list.

Terminals, databases, remote desktops and an editor, for Apple Vision Pro, Mac, iPad and iPhone. You add a machine once. Each machine lists its services, and Connect opens the one you want.

Apple Vision Pro, in the simulator's living room: a terminal on alpha running btop. Its CPU graph rises at the right beside sixteen cores; below are memory, the network and the shop's processes, with shop-web selected. The room shows through the window's glass. — A terminal on Apple Vision Pro, running btop, with the room behind its glass. Every machine in these pictures is made up.

Vision Pro first

It started as an SSH client for Apple Vision Pro, and the headset still leads the design. Each session is a normal window you place around you. A server's terminal, its database and its desktop can sit side by side in the room. A window you aren't using can shrink into a small glass orb, with its session live inside it, until you pinch it back.

Every window is glass. Opacity sets how much of the theme's colour is painted, Glass how much the room is frosted behind it; the pictures here use 78% and 50%.

The Mac, iPad and iPhone apps are the same app, adapted to each device. The Mac adds a local shell and menus. The iPhone gives each session the whole screen.

An honest note on testing. The current build is used every day on a Mac and an iPhone, and the headset runs it too: on 2026-10-18 all three had 0.4.476. Not every newer change has been checked on the headset yet.

A database window on Vision Pro: the shop database's tables in the sidebar, and the orders table open with its SELECT statement and a grid of orders, the room showing through. — **Databases.** The shop's orders: the query above, the rows below.

A remote desktop window on Vision Pro, connected to bravo: a made-up remote screen with a monitoring window charting CPU and a window listing the files in ~/shop. — **Remote desktops.** A machine's own screen, as large as you make the window.

The editor on Vision Pro: the shop project's files on the left, and ShippingAddress.swift open in a tab beside compose.yaml and README.md. — **Editor.** A project's files, and the one you're changing.

Pick up where you left off

Turn on Keep Sessions Running with tmux for a machine, and each terminal you open there runs in its own tmux session on the machine. A dropped connection, a closed window or a quit app leaves the work running. The machine needs tmux.

Active on Vision Pro: tmux sessions running on alpha (shop, open elsewhere; jobs, detached), on build (release, open elsewhere) and on nas (backups, detached), each with its repository and branch or folder, and when it was last used. — **Move a session between devices.** Active lists what runs in tmux on each machine, open on another device or detached. Choose one to join it here, or take it over. Start a build on the Mac and watch it from the headset.

Workgroups on Vision Pro: the Shop workgroup's startup plan, four terminals on three machines: web and jobs on alpha, release on build and backups on nas, each with its address and startup command. — **Workgroups that come back.** A saved set of terminals, each keeping its own tmux session. After a quit, a crash or an update, the windows come back on the same sessions with everything still running, and a startup command never runs into a session that is still going.

On the Mac

A terminal window on a Mac with its sidebar open, listing the terminal on alpha, which is running btop: the CPU's graph and cores, memory, the network and the shop's processes. — **Terminal.** SSH with host keys you confirm, tabs in a sidebar, tmux sessions you pick up on any device, and the server’s files a click away.

The same window in the light appearance. — **Terminal.** SSH with host keys you confirm, tabs in a sidebar, tmux sessions you pick up on any device, and the server’s files a click away.

A database window on a Mac: the shop database's twelve tables in the sidebar with orders selected, its SELECT statement, and a grid of orders with their customer, date, status and total. — **Databases.** MySQL, PostgreSQL and SQLite: browse, filter and edit rows, follow foreign keys, write and explain queries.

A remote desktop window on a Mac, connected to bravo at 1920 × 1080: a made-up remote screen with a monitoring window charting CPU over the last hour and a window listing the files in ~/shop. — **Remote desktops.** RDP and VNC, with the remote resolution following your window.

The editor on a Mac: the shop project's files in the sidebar, three tabs (compose.yaml, README.md and ShippingAddress.swift), and ShippingAddress.swift open with its Swift highlighted. — **Editor.** Files on this device or on a server, with highlighting, previews, and viewers for pictures, PDFs and 3D models.

What it does

Four tools share one library. You add a machine once, with its address. Then you add the ways in: a terminal, a database, a desktop. The address, keys and trust you set up once are used by every tool that needs them.

Terminal

SSH with host-key pinning, password and key sign-in, tabs, workgroups, port forwarding and an SFTP file browser. Sessions kept in tmux that you pick up on any device. A local shell on the Mac.

Databases

MySQL, PostgreSQL and SQLite. Browse, filter and edit rows, follow foreign keys, write and explain queries. Reach a server directly with TLS, or through the machine's own SSH connection.

Remote desktops

RDP and VNC. The remote resolution can follow your window. Audio and a shared clipboard, with formatting and images over RDP, when you turn them on.

Editor

Files on this device or on a server. Projects with a file tree, highlighting for fifteen languages, previews for Markdown, HTML, SVG and CSV, and viewers for pictures, PDFs, video, audio and 3D models.

The library

One list of hosts, with favorites, collections and search. It syncs through iCloud. Credentials sync through iCloud Keychain. Widgets show your machines and what's open, and Show All Windows shows every open session as a live picture.

Why one app

A machine usually offers several ways in. The common setup is one app per protocol. Each app keeps its own list of the same machines and its own settings. Glass Power Tools keeps one list instead. Whether that fits how you work is for you to judge.

The library on a Mac, in Dark Mode. All Connections lists six machines (This Mac, alpha, bravo, build, nas and win) with an icon for each service. Beside it, Your Library counts 6 machines and 8 services, a bar chart shows 181 connections over the last 30 days on 3 devices, and Most used lists alpha, bravo and build. — The one list, on a Mac, with a month of connections from three devices.

iPad and iPhone

The same library and the same machines. The iPhone gives each session the whole screen.

An iPad in Dark Mode showing the library: the machines on the left; on the right, Your Library's counts, a month of connections as a bar chart (189 on 3 devices) and the machines used most. — **iPad.** The library, with a month of connections.

An iPhone showing the terminal on alpha across the whole screen, running btop: the CPU's graph and cores, memory and the shop's processes. — **iPhone.** btop on alpha, across the whole screen.

What leaves your devices

Today the app connects to three kinds of place, and no others. When the Mac app ships it will also check an update feed; it asks on its second launch whether to do that automatically.

The servers you add. Only when you connect to them.
iCloud. Your host library syncs through your private iCloud database. Passwords, keys and host-key pins sync through iCloud Keychain, except a password you protect with Face ID or Touch ID, which stays on its device. Keys made in the Secure Enclave never leave the device they were made on.
Tailscale's API, only if you connect a Tailscale account to find your devices.

There are no analytics and no telemetry. Secrets live in the Keychain, apart from your settings. The database assistant runs on your device through Apple Intelligence, and the help lists exactly what it is given.

What it asks of you

Today

It is not released. It is in daily use and being prepared for release. If you want it now, you build it from source. You need a Mac with Apple silicon and Xcode 27, and you sign it under your own Apple Developer team.

It runs on macOS 26, iOS and iPadOS 26, and visionOS 26 or later.

When it ships

The Mac app will be signed with a Developer ID, notarized by Apple, and updated through Sparkle. It will not be in the Mac App Store, because a terminal cannot work inside App Sandbox. It has to start your shell and reach your files, tools and SSH agent.

The iPhone, iPad and Vision Pro apps will come through TestFlight, then the App Store.

Leaving

You should be able to stop using a tool without losing what you put into it. Here is what that looks like.

The code is MIT licensed. You can read it, change it and build it yourself.
It speaks standard protocols: SSH, SFTP, the MySQL and PostgreSQL protocols, RDP and VNC. Your servers need nothing from this app. Any other client can reach them the same way.
Imported SSH keys are ordinary OpenSSH keys, the same format other SSH clients use.
A SQLite file is opened as a private copy. Your original is never changed.
Your editor files stay where they are, on your device or your server. Removing a project from the list does not touch its folder.

What you cannot take with you yet: the list of hosts and services itself has no export. If you leave, you enter it again in the next app.

And one cost that is permanent: a key made in the Secure Enclave cannot be exported. That is what makes it safe. If you leave, add a different key to the servers that use it first.

Who made it

One developer, Michael Sitarzewski, whose name is on the licence. Nothing is sold today, because nothing is released. The app's About page has a Sponsor link.

If people use it, the author gains standing from it. That is a real interest, so it is written down here.

Check it yourself

You should not have to take this page's word for any of it.

The source. It will be public at github.com/msitarzewski/GlassPowerTools. It is MIT licensed.
What is verified, and how. The repository's memory-bank/progress.md says what was tested on real hardware and servers, and what was not.
Third-party code. THIRD-PARTY-NOTICES.md lists every component, its licence and the exact revision. Every local change to carried code is written down beside it.
The help. It was written from the app's code, including what the app does not support. Read the help.
Security. How it protects credentials, what it does not protect, and how to report a problem.

That is what it is, what it is not yet, and how to check. Whether one library of machines suits the way you work is yours to decide.
