Software under its own name

Hyperion Labs makes and sells its own software, and whoever buys it owns it: it runs on the buyer's own machines and keeps working without the company. One product is coming soon, and more are in development.

Sigil

Instant messaging, as it should have stayed.

Coming soon

The Sigil client: a group conversation with three members, the server list, conversations and contacts beside it
A group conversation in the Sigil client on Windows, in its dark theme.

Sigil is a messenger for people who would rather not hand their conversations to a service. It runs on a server its owner controls, from a spare machine at home to a rented one in a data center, and every message is sealed end to end before it leaves the sender's device.

Hyperion Labs operates no messaging service and holds no accounts. The company keeps license records, and nothing about who uses a server.
