SOLAS

Built by people who
work on boats.

Built by a team of maritime professionals and engineers who understand what captains, engineers, and crew actually need — because we've been there.

Software that works at sea.

Most vessel management software assumes you have reliable internet. We don't. VesselOS runs entirely on the vessel's onboard network — no cloud dependency, no subscription gatekeeping, no data leaving the boat unless you want it to.

VesselOS started as a replacement for a legacy onboard system that couldn't keep up. It grew into a platform that handles everything from GMDSS radio logs to tank sounding records — all from a single interface designed for bridge watchkeeping conditions.

Your data stays onboard.

Scheduled backups to network storage. SQLite database with full attachment archiving. No third-party servers between you and your compliance records.
