Lantern is now open by invite
A quieter place to keep your photographs.
OMSR Tech builds small, fast tools and gives them away. Everything here runs in your browser or on one machine you can point at — never in someone else's advertising pipeline.
Everything orbits Lantern. Tap a dot to visit it.
The main thing
Lantern
A small, warm, private-by-default photo network. New accounts start closed, messages are sealed on your device before they are sent, and there are no follower counts, no recommendation engine and no streaks to keep.
It runs on a single computer on a shelf rather than in a data centre — which is why every photo stays on that machine, and why it is sometimes asleep.
