brew install concord

Or with the tap for the latest version:

brew install chojs23/tap/concord

npm install -g @chojs23/concord

You can also run Concord without a global install:

npx @chojs23/concord

The npm package installs a prebuilt binary from the GitHub Release artifacts.

Install native dependencies first.

On macOS with Homebrew:

brew install opus pkg-config

On Fedora:

sudo dnf install opus-devel alsa-lib-devel pkgconf-pkg-config

On Debian or Ubuntu:

sudo apt install libopus-dev libasound2-dev pkg-config

cargo install concord --locked

To install without local voice playback and microphone support:

cargo install concord --locked --no-default-features

To install the latest unreleased version directly from the Git repository:

cargo install --locked --git https://github.com/chojs23/concord

Run without installing (requires flakes enabled):

nix run github:chojs23/concord

Install into your profile:

nix profile install github:chojs23/concord

Or add the flake as an input in your own flake.nix:

{
  inputs.concord.url = "github:chojs23/concord";
}

Install the latest release with the cargo-dist shell installer:

curl --proto '=https' --tlsv1.2 -LsSf https://github.com/chojs23/concord/releases/latest/download/concord-installer.sh | sh

On Windows, use the PowerShell installer instead:

powershell -ExecutionPolicy Bypass -c "irm https://github.com/chojs23/concord/releases/latest/download/concord-installer.ps1 | iex"

The installer places concord under $CARGO_HOME/bin, which is usually ~/.cargo/bin on Unix and %USERPROFILE%\.cargo\bin on Windows.

You need the Rust stable toolchain, Cargo, and the native dependencies listed in the Cargo install section.

git clone https://github.com/chojs23/concord.git
cd concord
cargo build --release

The release binary is produced at:

target/release/concord

To build without local voice playback and microphone support, disable default features:

cargo build --release --no-default-features

On WSLg, audio is usually exposed through PulseAudio instead of a real ALSA sound card. If playback does not start, check that PulseAudio and ALSA routing work before debugging Discord voice itself:

pactl info
paplay /usr/share/sounds/alsa/Front_Center.wav
aplay -D pulse /usr/share/sounds/alsa/Front_Center.wav

• Token : paste an existing Discord token.
• Email / Password : login with credentials. MFA (TOTP, SMS) is fully supported.
• QR Code : scan the code from the Discord mobile app.

Email and QR code logins may trigger a CAPTCHA challenge on Discord's side. We cannot solve that, so I strongly recommend using token authentication.

By default, tokens are saved in the system keychain when available. In the default auto mode, Concord falls back to its state directory when keychain storage is unavailable. See the Security section below for details.

• Browse servers with guild folder grouping
• Navigate text channels, threads, and forum channels
• View and filter forum posts (active / archived)
• Load pinned messages per channel
• Open channel actions for pinned messages, thread lists, and mark-as-read
• Join and leave voice channels
• Highlight active voice speakers in voice channel participant rows
• Track unread messages and mention counts per channel
• Mute and unmute channels and servers
• Leave the selected server after confirmation

• Send, edit, and delete messages
• Upload / Download attachments
• Search messages with filters with /
• Use @mention autocomplete
• Use custom emoji from other servers when your account supports it
• Send custom emoji your account cannot use directly as image links when enabled
• View full message history
• Rich content display (embeds, attachments, stickers, and mentions)
• Detect URLs in message bodies and markdown links, then open them in your default browser
• Direct message shortcuts for copy, reply, edit, delete, reactions, URL opening, and image viewing. More message actions are available from the action menu.

Concord renders a practical subset of Discord-style Markdown in message bodies:

• Headings: # H1, ## H2, ### H3
• Quotes: > quoted text
• Bullets: - item and * item
• Inline styles: **bold**, *italic*, and `inline code`
• Fenced code blocks with optional language labels, rendered as compact boxes with syntax highlighting
• Raw URLs and markdown link destinations are underlined and can be opened from message actions

• View, add, and remove emoji reactions (Unicode and custom server emoji)
• Use custom emoji from other servers as reactions when your account supports it
• Browse who reacted with a specific emoji
• View and vote on polls

Image rendering is powered by ratatui-image. On startup, Concord queries the terminal to detect the best available graphics protocol. Supported protocols:

• Kitty Graphics Protocol - Kitty, WezTerm, Ghostty, etc.
• iTerm2 Inline Images - iTerm2, WezTerm, mintty, etc.
• Sixel - foot, mlterm, xterm (if compiled with Sixel support), etc.
• Halfblocks (fallback) - works on any terminal, but uses block characters instead of true pixels.

If your terminal does not support any graphics protocol, images will be rendered as halfblock approximations. For the best experience, use a terminal that supports the Kitty or iTerm2 protocol.

You can toggle image viewing on or off in the configuration file. When image viewing is off, attachments and emojis will be shown as text placeholders.

• Member list with grouping
• Search members in server
• Presence indicators (Online, Idle, DND, Offline)
• Configure user profile and custom activity status

• Live "user is typing..." indicators
• Unread message tracking with mention counts
• Mark server, channel as read

• Desktop notifications for Discord messages that pass your Discord notification settings
• Active channel notifications are suppressed so Concord does not notify for the conversation you are already viewing
• Voice join and leave notification sounds while you are connected to voice. You can keep the built-in tones or configure custom WAV files.

⚠️ Keymap action names and default bindings may have breaking changes between releases.

All default key settings in this section can be customized. See Keymap options for the config format and supported actions.

Concord has a four-pane. Guilds (1), Channels (2), Messages (3), Members (4)

With default vim-style navigation:

Ctrl+n and Ctrl+p are fixed row movement keys. The default j and k row movement keys are SelectNext and SelectPrevious and can be changed in keymap.toml.

Press Space to open the leader shortcut window.

Focus a pane, then press Space, a to open actions for that pane. Action shortcuts are shown inside the leader popup and only run when the action is enabled. In the Messages pane, the selected message also supports these direct shortcuts:

Message shortcuts:

Message action menu shortcuts:

When the attachment viewer is open, press d to download the current attachment directly.

Server actions:

Channel actions:

Voice commands:

You can paste copied files into the composer to attach them. Pending uploads are shown above the input before sending.

When the @mention picker is open, use Up / Down, Ctrl+p / Ctrl+n, Tab, or Enter to choose a mention.

Type : plus at least two letters, such as :he, to pick Unicode, server, or cross-server custom emoji while writing a message.

When emojis_as_links is enabled, custom emoji your account cannot send directly are inserted as Discord image links instead.

To react from the composer, select a message, enter insert mode, then type +:. The reaction picker opens for that message. Press / to search, Enter to lock the filter, then Enter again or use a shown shortcut to react.

When the composer input starts with a slash /, the command suggestion popup

Concord options are stored under Concord's config directory. If XDG_CONFIG_HOME is set, Concord uses config.toml for app options and keymap.toml for key settings. Otherwise it uses the platform config directory.

Local UI state and plaintext fallback credentials are stored under Concord's state directory instead. If XDG_STATE_HOME is set, Concord uses $XDG_STATE_HOME/concord/state.toml and $XDG_STATE_HOME/concord/credentials.toml. Otherwise it uses ~/.local/state/concord/state.toml and ~/.local/state/concord/credentials.toml.

You can change some configuration from the in-app Options menu, and Concord saves them back to config.toml. Key settings are read from keymap.toml.

image_preview_quality supports these values:

• efficient: smaller preview requests to reduce bandwidth and memory use.
• balanced: default quality with bounded resource use.
• high: sharper resized previews using lossless quality.
• original: request the original source image for previews when possible.

This setting only applies to attachment, embed, and attachment viewer previews. Avatars and custom emoji keep their separate small-image behavior.

credentials.store supports these values:

• auto: try the system keychain first, then fall back to the state-file credential store.
• keychain: use only the system keychain. If keychain storage is unavailable, the token is not saved.
• plain: use only the plain-text state-file credential store.

Concord is designed to stay lightweight in normal terminal use. In observed typical use, it usually uses about 20-40 MB of memory.

Image-heavy screens can temporarily use more memory because compressed image bytes need to be decoded before they can be rendered in the terminal. When many images are loaded, memory can briefly rise to around 100-200 MB while decoding and then drop again as work completes and caches are pruned.

To keep resource usage bounded, Concord limits media work in several places:

• Attachment previews are downloaded with an 8 MiB per-preview cap.
• Attachment downloads are capped at 64 MiB.
• Up to 4 attachment previews are fetched at once.
• Up to 2 inline image previews are decoded at once.
• Inline image previews, avatars, and custom emoji use small LRU caches.
• Image preview requests prefer resized Discord proxy URLs sized for the terminal instead of original full-size media when possible.
• The preview quality preset can lower preview source dimensions or opt into original source images. It does not change avatar or custom emoji sizing.

Message history is also cached with a per-channel limit, so long-running sessions do not keep every message in memory forever.

Honestly, no.

There are some path that did trigger a account block:

• Trying to create a new DM channel and send a message to an unknown user(meaning there was no pre-existing DM created through the Discord client) can immediately block your account temporarily.
• Some features that requires a hCapcha challenge on Discord's side.

Other features have not caused blocks in my testing.

That said, Concord is not an official Discord client. Using unofficial clients, automated user accounts, or self-bots can violate Discord's TOS, so there is always some risk. Use it at your own discretion.

No. If Discord requires a CAPTCHA during login, use token login instead.

• By default, tokens are stored in the system keychain when available.
• On Linux, keychain storage uses Secret Service when a compatible service is available.
• In credentials.store = "auto", Concord falls back to plain text credentials under Concord's state directory when keychain storage is unavailable. In keychain mode, Concord does not fall back to plain storage. Keep fallback credential files secure and do not share them. You can use a token from that file to log in to the official Discord client, so treat it like a password.
• On Unix, the fallback credential's parent directory is created with 0700 and the credential file with 0600 permissions.
