Moment is a free and open-source Matrix powerclient for Linux, so getting started means three things: getting the client onto your machine, connecting it to a Matrix account, and then tuning it to your liking. The official site points to GitLab for installation and lists keybindings, themes, and configuration as first-class features, which tells you the intended path: install, sign in, then customize.

What Moment Is (and What It Is Not)

Moment is a maintained fork of Mirage, built specifically for Linux. It is a Matrix client, not a Matrix server — you still need an account on some homeserver to use it. The site describes it as:

• Secure — complete end-to-end encryption
• Decentralized — you pick who hosts your account, or host your own server
• Compatible — works with many clients and bridges to different protocols
• Keyboard operable — dedicated bindings for every function
• Responsive — adapts to any window size, mobile included
• Customizable — change any binding or functionality
• Multi-account — use several accounts efficiently
• Scalable — unlimited chats without getting lost
• Themed — swap themes to make Moment yours

If you have not used Matrix before, the practical takeaway is that Moment is the front end; your account and message history live on a homeserver you choose.

Step 1: Get the Software

The official site directs you to GitLab for installation. That is the authoritative source for how to obtain and build Moment, so start there rather than at a third-party mirror.

Before you install, confirm two things:

1. You are on Linux. Moment is described as a Linux client; the site does not present it as a Windows or macOS application.
2. You have a Matrix account or are ready to create one. If you do not, decide on a homeserver first — either an existing public one or your own, since the client is decentralized by design.

The site itself does not publish package names, download links, or a step-by-step install command in the material available, so treat GitLab as the place where those specifics live. Do not assume a particular package manager or distribution is supported until you check there.

Step 2: Connect Your Matrix Account

Once Moment is running, you sign in with your Matrix account. Because Moment supports multi-account use, you can add more than one account and switch between them rather than running separate clients.

Two decisions matter here:

• Which homeserver you trust. Moment is decentralized: you choose who hosts your account, or you host your own server. This is a trust decision, not a technical formality.
• Whether you need bridges. The site states Moment is compatible with many clients and bridges to different protocols, so if you want to reach people on other networks, that is handled through Matrix bridging rather than inside Moment itself.

End-to-end encryption is described as complete, so encrypted rooms should work once you are signed in — but encryption depends on your account and room setup, not on the client alone.

Step 3: Make It Yours

This is where Moment differs from a bare-bones client. The site lists keybindings, themes, and configuration as top-level items, and describes the client as keyboard operable with dedicated bindings for every functionality.

Practical starting points:

Because every function has a binding and any binding can be changed, the fastest way to learn Moment is to read the keybindings list once, then remap anything that clashes with habits from your previous client.

Common Sticking Points

• Looking for a download page on the website. The site points to GitLab for installation; that is where the real instructions are.
• Expecting Moment to provide an account. It does not — it is a client. You need a homeserver.
• Assuming cross-platform support. The material describes Moment as a Linux client. Do not plan around Windows or macOS builds without verifying on GitLab.
• Skipping the keybindings. Since the client is designed to be fully keyboard operable, ignoring the bindings means missing much of what makes it different.

Where to Go Next

If you want to understand the project's lineage before committing, the relationship to Mirage is worth reading up on — Moment is a maintained fork, which affects where fixes and features come from. If customization is your priority, go straight to the keybindings and themes documentation after your first sign-in.

Moment is highly customizable for a Matrix client: every function has a dedicated keyboard binding, any binding or function can be changed, themes can be swapped, and the interface adapts to any window size, including mobile. The limits are that these options are described at a feature level on the official site — there is no published list of specific themes or a full default keymap, so you should expect to configure it yourself rather than pick from a documented catalog.

What you can change

Keyboard-first customization

The distinguishing claim is that customization is not just cosmetic. Because every functionality has a dedicated binding and any binding can be changed, you can reshape the client around your own workflow instead of learning a fixed shortcut set. For example, if you want to jump between many rooms without touching the mouse, you would remap room navigation to keys you already use in other tools.

The site does not publish the default keymap, so the first step in practice is to open the keybindings section and read what is currently assigned before changing anything. That also tells you which functions exist to be remapped.

Themes and appearance

Themes are presented as a way to "make Moment yours," which means appearance is intended to be changed rather than fixed. What is not stated is how themes are distributed or whether there is a gallery — so treat theming as something you configure, not something you browse and install from a store.

Layout and multi-account

Two forms of customization are structural rather than visual:

• Responsive layout — the interface adapts to any window size, mobile included, so you are not locked to a desktop-shaped window.
• Multi-account — you can run several accounts efficiently, which matters if you separate work and personal Matrix identities.

What is not documented here

The official page describes capabilities, not specifics. It does not list available themes, default keybindings, configuration file formats, or installation steps beyond the presence of an install section. If you need exact syntax or a theme list, that information has to come from the client itself after installation.

Who this suits

Moment fits you if keyboard-driven control and remapping matter more to you than a curated set of built-in looks. If you want a client where appearance and shortcuts are decided for you, the level of configurability here is more than you need. Moment is also described as a maintained fork of Mirage, so its customization model inherits from that lineage rather than starting fresh.

Moment is a maintained fork of Mirage. That single fact answers the core question: Moment is not a from-scratch Matrix client, but a continuation of Mirage's codebase that is kept up to date by its own maintainers. If you are choosing between the two, the practical difference is maintenance status rather than a fundamentally different feature set.

What "fork" means here

A fork is a copy of an existing project that then develops on its own path. In Moment's case, the official site states directly that "Moment is a maintained fork of Mirage." Two things follow from that wording:

• Inherited foundation. Moment starts from Mirage's existing functionality rather than a blank slate. The features listed on its site — end-to-end encryption, decentralization, multi-account support, keyboard bindings, themes, and responsive layout — describe the client as it exists now, built on that inherited base.
• Independent upkeep. The word "maintained" signals that someone is actively keeping the fork current. This is the part that distinguishes it from the original project's status.

Why the distinction matters to a user

For most people evaluating a Matrix client, the fork relationship is only relevant insofar as it affects what they actually use. The relevant question is not "is it a fork?" but "is the version I install being looked after?"

If you were already considering Mirage, Moment is the variant whose maintainers are presenting it as actively kept up. If you were not, the fork detail is mostly background — the feature list is what you would evaluate either way.

What this does not tell you

The site describes Moment as a maintained fork, but it does not publish a comparison against Mirage, a changelog of divergences, or a statement about how far the two have drifted apart. So you cannot conclude from this page alone:

• Which specific features Moment has added beyond Mirage.
• Whether Mirage is still maintained in parallel.
• How frequently Moment receives updates.

Those are the questions to check directly in the project's repository or release history if the fork relationship is decisive for you.

A reasonable way to decide

1. If you want a Linux Matrix client with encryption, multi-account support, and keyboard-driven control, evaluate Moment on its own listed features — the fork origin does not change what it does.
2. If you specifically want the actively maintained line of the Mirage codebase, Moment is the one described that way, and it is the safer default between the two on that criterion alone.
3. If you need to know exactly how the two differ, treat the official site as insufficient and go to the source repository, where commits and releases will show the actual divergence.

In short: Moment is Mirage's codebase under continued maintenance, and that maintenance claim — not the fork label itself — is the reason to prefer it.

Moment is a free and open-source Matrix powerclient for Linux. It is a maintained fork of Mirage, which means it continues development from the Mirage codebase rather than starting from scratch. If you use Matrix for chat and want a Linux desktop client that emphasizes keyboard control, customization, and end-to-end encryption, Moment is aimed at you. If you need a client for Windows, macOS, iOS, or Android as your primary platform, the official description only claims Linux support, so treat other platforms as unconfirmed.

What Moment actually is

Moment is a client for Matrix, an open protocol for decentralized, real-time communication. A Matrix client is the app you use to send and receive messages; the server (homeserver) stores and routes them. Moment is the client layer, not the server itself.

The site describes it as a "powerclient," signaling that it targets users who want more control than a minimal chat app offers.

Core characteristics

The official page lists these features:

• Free and open-source — no license fee is stated, and the source is open.
• Secure — complete end-to-end encryption.
• Decentralized — you pick who you trust as your host, or host your own server.
• Compatible — works with many clients and bridges to different protocols.
• Keyboard operable — dedicated keybindings for every function.
• Responsive — adapts to any window size, including mobile-sized windows.
• Customizable — change any binding or functionality.
• Multi-account — use many accounts efficiently.
• Scalable — unlimited chats without getting lost.
• Themes — change your theme to make Moment yours.

Who it is for

Moment fits Linux users who:

• Already use Matrix or want to try it.
• Prefer keyboard-driven workflows over mouse-heavy interfaces.
• Want to self-host their homeserver or choose their own host.
• Run multiple Matrix accounts and want them in one client.
• Like customizing keybindings and themes.

It is less suited to you if you want a client that runs natively on non-Linux systems, or if you prefer a simple, zero-configuration chat app.

How it relates to Mirage

Moment is a maintained fork of Mirage. A fork copies an existing project and develops it independently. "Maintained" means the fork is actively kept up rather than abandoned. In practice, this tells you Moment inherits Mirage's design and adds ongoing development on top. If you were evaluating Mirage, Moment is the version the project itself points to as maintained.

What to check before committing

• Platform: confirm Linux is your target, since that is the only platform named.
• Homeserver: decide whether you will use an existing Matrix host or run your own server.
• Encryption: end-to-end encryption is stated, but verify it works with the rooms and bridges you rely on.
• Bridges: the page says it bridges to different protocols; check that the specific networks you need are covered.
• Pricing and login: the source material does not state pricing terms or login requirements, so do not assume it is free of account requirements or restrictions beyond "free and open-source."

For the current install steps, keybindings, and configuration options, use the official site's GitLab, Install, Keybindings, and Configure sections, which the page itself references.

Moment (mx-moment.xyz) is a free and open-source Matrix "powerclient" for Linux, built as a maintained fork of Mirage. It supports end-to-end encryption, decentralized homeserver choice, multi-account use, unlimited chats, and bridging to other protocols through Matrix bridges. It is keyboard-operable, themeable, and responsive down to mobile-sized windows. If you already use Matrix and want a Linux desktop client that exposes every function through keybindings and deep customization, Moment is aimed at you; if you need a client on Windows, macOS, iOS, or Android, or you want a hosted service rather than software you install, it is not.

Matrix client compatibility

Moment is described as "compatible with many clients." In Matrix terms, that means it speaks the standard Matrix protocol, so it can exchange messages with users on other Matrix clients and other homeservers. Compatibility here is about the protocol, not about importing another client's settings or UI — you sign in to your existing Matrix account and your rooms and contacts remain reachable.

Practical implications:

• You can keep using your current Matrix account and homeserver; Moment is a client, not a server.
• Other people in your rooms do not need Moment. They can stay on Element, Cinny, or any other Matrix client.
• Because it is a fork of Mirage, its behavior and feature set follow that lineage rather than being built from scratch.

Protocol bridging

Moment's page lists "bridges to different protocols" as a compatibility feature. This is a Matrix-level capability: bridges run on the homeserver side and translate between Matrix and networks such as IRC, XMPP, Discord, Slack, Telegram, or WhatsApp. Moment displays the resulting rooms like any other Matrix room.

What this means for you:

• The bridge is not configured inside Moment. You (or your homeserver admin) set it up on the server, then the bridged rooms appear in your room list.
• Whether a specific network is available depends on which bridges your homeserver runs, not on Moment itself.
• If you self-host, you control which bridges exist; if you use someone else's homeserver, ask them what is bridged.

Encryption and hosting

Two properties are stated directly:

The decentralization point is a choice, not a requirement. You can point Moment at an existing homeserver you already trust, or host your own. Moment does not host anything for you — it is the client on your machine.

Accounts, chats, and customization

• Multi-account: use several Matrix accounts efficiently, for example a personal account and a work account, without switching applications.
• Scalable: unlimited chats without getting lost, which matters if you join many rooms or run many bridges.
• Keyboard operable: dedicated bindings for every function, so you can drive the whole client without a mouse.
• Customizable: change any binding or functionality.
• Themes: change the theme to make Moment yours.
• Responsive: adapts to any window size, including mobile-sized layouts.

How to decide

Choose Moment if all of these hold:

1. You are on Linux.
2. You already have a Matrix account or are willing to create one on a homeserver you trust.
3. You want keyboard-first operation and per-function rebinding.
4. You want to theme the client and run multiple accounts in one window.

Look elsewhere if any of these hold:

• You need a client for Windows, macOS, iOS, or Android.
• You want a browser-based client with nothing to install.
• You expect bridges to be configured inside the client rather than on the homeserver.

Getting started

1. Install Moment on Linux from its official site (mx-moment.xyz).
2. Sign in with your existing Matrix account, or register on a homeserver you trust — or your own.
3. Configure keybindings and themes to match how you work.
4. Add additional accounts if you need them.
5. For other protocols, confirm with your homeserver admin which bridges are running, then join the bridged rooms.

The main friction point is bridging: it lives on the server, so a client-side setting will not create a bridge that does not exist. Everything else — encryption, multi-account, keybindings, themes — is available from the client once you are signed in.
