Seafarer Index is a free, login-optional reference portal for the world's roughly 1.9 million seafarers. Ports, ships, companies, flag states, STCW certificates, maritime terminology, wage scales, seafarer welfare centres, and crisis helplines — each entry gets its own permanent URL you can bookmark, link, or share in a group chat.
Working seafarers spend most of their careers away from reliable internet. When they do have signal, the information they need — the number of a seafarer centre in the next port, whether a flag state is ITF-listed, what the STCW Advanced Fire Fighting refresher costs in Manila — is fragmented across a dozen subscription databases, industry PDFs, and outdated forum threads.
Seafarer Index is the opposite: one URL-addressable page per thing, built from public sources, designed to load over bad satellite links, and indexable on Google so you can find it with a phone search in the messroom.
Open-source stack: Next.js 16 (React Server Components), Tailwind CSS v4, Supabase (Postgres + Auth), hosted on Netlify. All text, database schema, and build scripts are in the GitHub repo. Send corrections via pull request or the forum.
Seafarer Index is self-funded. There are no ads, no paywalls, no data sales. If you work in maritime welfare and want to underwrite the hosting so this stays free, get in touch.
