Flagship turns a spare computer into your own cloud. Your phone holds the keys. Your apps, files and backups live on a server you own: an old PC, a mini PC, or a virtual machine on a computer you already use. Each server gets its own web address with a real green padlock, and the encryption ends on your server, not on ours. Flagship can't read what your apps send. WHAT YOU CAN DO • Set up a server in about ten minutes with Flagship Studio on your computer. • Approve your server's start with Face ID, or let it start on its own if you choose. • Build apps by describing them, or install them from a git repository. • Invite family and friends to one app at a time. They get that app, never your keys. • Back up your servers to your phone or to your other servers. Only your account can open the backups. • Run AI models on your own server. Your prompts and data stay there. • See your servers on Apple Watch, and approve a start from your wrist. NEW IN 0.3 • The first time you approve a new server, your phone keeps that server's own key and checks it every time after. It shows a six-digit code to compare with the server's screen. • Your own page at voi.ci/your-name: a photo, a short bio, your links and posts. People with a Flagship account can send you messages from it, end-to-end encrypted. They appear as visitors, never by name. • Local AI: download a model to your server and use it in your apps and builds. Nothing is sent anywhere. • Apps get their own database, can be made of several parts, and can be small WebAssembly programs. • An app that needs a graphics card waits for your approval. • Choose for each app whether updates wait for you, wait a week, or install at once. • Server updates prove they are healthy, or step back on their own. • The server software was rebuilt for security: it no longer runs as root, keeps its keys in a separate service, and installs only signed packages. • If flagshipserver.com can't be reached, your phone can still find your server on your home Wi-Fi, show its status, start and stop apps, and make a backup. • Choose how long each server keeps serving its apps if no admin opens Flagship: 7 days, 30 days or no time limit. • Check that your server runs the official Node.js from nodejs.org, against a list Flagship signs. • English, Spanish, French, German, Brazilian Portuguese, Japanese and Simplified Chinese. PRIVACY, PLAINLY • Encryption ends on your server. Our relay passes the encrypted traffic along and sees connection metadata: which server, when, and how much. • No email, no password, no phone number. Your account is a set of keys on your devices. • An AI model never learns who or where you are. • The code is public at github.com/ibisllc/flagship. Flagship is free. There is nothing to buy. You need a server: a spare computer, or a computer that runs Flagship Studio (macOS and Windows; Linux is experimental).
