End-to-end encrypted messenger for organisations · self-hosted
Anthill
Not even the server
can read your messages.
Locked on the sender’s device, opened only on the recipient’s.
Own engine in Rust · MLS (RFC 9420)
Not just the text โ threads, mentions and pins live inside the ciphertext. The server does not even know the shape of the conversation.
The keys live only on the devices.
The relay server’s code contains no decryption module. Not “we don’t look” โ “we can’t.”
If it is awkward, people go elsewhere.
Everything a work messenger needs, kept inside the ciphertext.
Direct · group · broadcast
Keys roll automatically when members change
Threads · mentions · pins
Even the structure stays encrypted
Encrypted attachments
Files are locked on the device before upload
Voice · video calls
Signalling is end-to-end encrypted too
Web · iOS · Android
One Rust engine drives all three
Multi-device
One QR scan registers a new device
Account takeover defence
Registration lock and a recovery key
Key transparency
A public log exposes any silent key swap
Verifiable reporting
Unreadable to the server, still provable
We do not ask you to trust us.
Standards, structure and verification instead.
Standard cryptography
Built on openmls, a reviewed implementation of the IETF MLS standard. We write no cryptography of our own.
A structurally blind server
The relay is a separate codebase and ships without any decryption module.
Key transparency
Every key change lands in a public log. Monitors compare signed checkpoints and catch any substitution.
Testing and audit
245 automated tests and repeated adversarial review. A third-party cryptographic audit runs before you go live.
Built to fit your infrastructure.
Requirements
We scope it around your size and your authentication policy.
Deploy and verify
The server goes up; web and mobile clients are configured.
Handover
Backups and monitoring in place, then operations pass to you.
