Simple on the outside
It feels like messaging.
It works almost anywhere.
You should not need to understand networks or encryption. Komms handles the complicated part in the background.
Connect with someone
Share a link, scan a code, or meet in person. No phone number or email address required.
Message like normal
Send private messages and share with groups in an app made to feel familiar from day one.
Komms finds a way
Online or off, Komms chooses an available route. Your conversation stays the same.
The alpha today
A real messenger.
Not a protocol demo.
The core product now works across desktop, Android, and iOS, with public desktop and Android test packages. “Shipped alpha” means implemented and tested—not audited, stable, or ready for high-risk use.
Shipped alpha Release qualification remains
Shipped alpha
Rich private conversations
Text, safe formatting, authenticated edits, voice notes, scheduled messages, and honest queued, sent, and delivered states.
Shipped alpha
Photos, files, and voice notes
Share bounded attachments, edit still images locally, and send view-once media. Bulk data waits for a faster link instead of flooding a radio mesh.
Shipped alpha
Private groups
Sender-key group chats with encrypted mentions, convergent polls, owner/admin/member roles, membership controls, and per-person delivery truth.
Audio alpha
Private live audio calls
Authenticated, encrypted audio over a fresh direct QUIC connection. Calls stay unavailable on relays, TCP, mailboxes, files, and radio; video remains gated on physical audio qualification.
Shipped alpha
Your chats, on your devices
Up to eight independently keyed devices, mutually confirmed nearby linking, encrypted sync, exact-device revocation, and mnemonic-protected local backups.
Shipped alpha
Privacy controls you choose
Disappearing messages, view-once media, screen protection, incognito-keyboard hints, safety-number verification, and key-change warnings.

Different on purpose
No public feed, no cloud account, and no pretending a 1,000-person video group can work over LoRa. Komms keeps the familiar messenger experience and changes the parts that require a central service.
Made for real life
Stay in touch when life gets patchy.
Most days, the internet works. Sometimes it does not. Komms is being designed for both.
Bad signal
Keep a group chat moving at a festival, on a train, or anywhere the network is crowded.
Internet outage
Reach family and neighbours through local connections when home internet goes down.
Far off-grid
Pair Komms with affordable radios to send messages over long distances without cell service.
One conversation, many routes
You keep talking.
Komms keeps trying.
A regular messenger usually needs its company's servers. Komms is designed to move the same sealed message through whatever is available.
Go under the hood⌁ Same sealed message
Private by design
Your conversations belong to the people in them.
Komms is designed without an account provider sitting in the middle. That means less information to collect, scan, sell, leak, or switch off.
What Komms can and cannot protect- ✓Messages are locked on your device
Only the intended people hold the keys to read them.
- ✓Your history stays with you
It is stored locally, encrypted, exportable, and truly deletable.
- ✓Anyone can inspect the code
Komms is open source and designed to stay that way.
An honest status update
Ready for testers. Not ready for trust without limits.
Komms 0.1 Alpha now has unsigned desktop installers and a debug-signed Android APK. Hands-on device and radio qualification, production signing, app-store distribution, hardening, and an independent security audit are still ahead.
Read the Alpha testing guideGood questions
The short, honest answers.
What exactly is Komms?
Komms is a private, open-source messaging app in development. It is designed to let devices communicate directly, so your conversations do not depend on one company or one central server.
Can I download it today?
Yes. Komms 0.1 Alpha has public test packages for Windows, macOS, Linux, and Android. Desktop packages are unsigned, the Android APK is debug-signed, and iOS remains source and Simulator only. Verify the published SHA256 checksums before installing.
Does it really work without the internet?
That is one of the main goals. The same private message is designed to travel over the internet, a nearby connection, an affordable radio, or even an encrypted file carried by a person.
Is it safe for high-risk situations?
Not today. Komms is still in development and has not completed an independent security audit. It should not yet be relied on by people in high-risk situations.
Who owns Komms?
Komms is an open-source project. Its public license means anyone can inspect it, improve it, or build on it, and public versions must keep their source open too.
Will it have the features I already use?
Much of that product surface now works in the alpha: rich text, editing, groups, files, voice notes, disappearing and view-once content, polls, roles, linked devices, backups, and direct audio calls. Stable release qualification and polish remain, and bandwidth-heavy features wait for a suitable connection.
