Everything you're used to from Slack
mssgs gives your group channels, DMs, voice calls, eight built-in games, file sharing, custom bots, webhooks and smart search. Work accounts add workflow automations.
What makes mssgs unique
Features you won't find in Slack, Teams or Discord
Access policy for your whole group
Restrict who can join your group. Only people with an email address on your domain? Invite-only? You have full control, without managing invite codes.
- Domain restriction (@company.com)
- From invite-only to public
- No invite code hassle
- Handy for work groups too
User Groups
Server-wide permissionsUser groups for your whole group
No more hassle with per-channel permissions. Create groups, assign rights, and manage everything centrally. Add someone to "Developers" and they automatically get access to all relevant channels.
- Permissions for the whole group
- Automatic channel access
- Easier than Discord roles
Owners
Shared ownership
Add multiple owners to your group. The primary owner cannot be removed, but other owners have the same rights. Perfect when you run the group together.
- Multiple owners possible
- Primary owner protected
- Not possible in Discord/Slack
Deploy completed
Custom triggers with webhooks
Type /command in any channel and automatically trigger a webhook. No bot needed, no code: just set it up visually and it's available across your whole group.
- Available across the whole group
- No bot or code needed
- Visual webhook configuration
- Not possible in Discord/Slack
Incoming DM request

DM Requests off by default
No unwanted DMs or spam. By default, others cannot message you. Anyone new sends a DM request first, and you accept or decline it.
- Privacy on by default
- You approve every new chat
- No spam or unwanted DMs
- Not possible in Discord/Slack
Community Moderation
In communities, we don't decide what is and isn't allowed: the community does. Volunteer moderators vote independently on reports. Work accounts manage their own moderation.
- Democratic decisions
- No corporate censorship
- Transparent process
- Only in communities
Ghost messages
Toggle the ghost icon and your messages disappear from everyone's chat right after they're read. No traces in the history, blurred when the window loses focus.
- Auto-delete after viewing
- Marked clearly with START / END markers
- Blurred when the window is unfocused
Voice recording in any chat
Tap the mic in any channel or DM. Preview your recording, redo it if you flubbed it, or send it instantly. Built right into the chat: no third-party tools needed.
- Live waveform while recording
- Preview before sending
- Cancel, restart or pause anytime
Share your location with friends
See where your friends are on a live map. Discover who's nearby, what they're up to and meet up faster. You decide who can see you and for how long.
- Per-friend privacy
- Auto-expires after the time you pick
- Activity status (walking, cycling, on the train...)
Met you in the noise.
Stayed for the quiet.
See what your friends are up to
A blue ring around an avatar means a new story is waiting. Tap to watch: friends only, no algorithm, no strangers.
- Friends-only, no public stories
- Auto-expires after 24 hours
- Blue ring while unviewed

- Filters, text and stickers
- Auto-expires in 24 hours

One-view photos
Send a photo that can only be seen once. After it's opened it's gone: for everyone, on every device. No screenshots, no second look.
- Disappears after first view
- Sender sees when (and on which device) it opened
- Works in any DM
Set Reminder
Reminders on any message

- Presets from 1 hour to 1 week
- Custom times
- Works across all your devices
Follow channels with push notifications
Right-click any channel and enable push notifications to get alerts on every new message, even when mssgs isn't open. No more missing important updates.
- Per-channel control
- Works on desktop and mobile
- Disable just as easily
Always know what's happening
Each DM shows what's new at a glance: Sent, Opened, Viewed. Streaks count up when you and a friend stay in touch every day.
- Sent / Opened / Viewed status
- Daily streak counter with a fire badge
- No more guessing if they saw it
Festival
Photo filters for your city
Anyone can design a photo filter and pin it to a spot: a festival, a campus, your neighborhood. Community moderators approve it, and everyone there can shoot with it.
- Pin it to any spot with a 1-10 km radius
- Community-reviewed before it goes live
- Use filters wherever you are
A whiteboard in every chat
Open the whiteboard, sketch your idea with brushes, colors and undo, and send it straight into the conversation as an image.
- Colors, brush sizes and an eraser
- Undo when it goes wrong
- Friends see you're drawing while you draw
Jump anywhere with ⌘K
One shortcut opens the quick switcher. Type a few letters and jump to any server, channel or DM. Your hands never leave the keyboard.
- Searches servers, channels and DMs at once
- Ctrl+K on Windows, ⌘K on Mac
- Ctrl/⌘ 1-9 hops between servers
Lock a chat behind your fingerprint
Give any DM its own passcode. Open it with Touch ID and it stays out of sight for anyone who borrows your screen.
- A separate passcode per conversation
- Touch ID unlock on Mac
- The code lives in your device keychain, not on our servers
A photo library, as a channel
Flip a channel into a photo channel and every shot lands in a date-grouped grid: a shared camera roll for your group.
- Grouped by date, like your camera roll
- Everyone can add photos
- Full-screen viewer built in
