Sweepline is a gesture-based dispatch tool for people, spaces, and systems. Connect to a server you run at home — or one shared by friends or family — then send signal events with directional sweeps or taps. These simple gesture can acknowledge a request, unlock a workflow, hand off responsibility, or trigger a physical system connected to the saved endpoint. Sweepline is intentionally small — like a Unix utility for your fingers. There is no feed, profile system, or social network. The app enables team communication, but does not offer direct messages or require logging into a centralized service. Sweepline does its best remembering ed25519 private keys, speaking http, and getting out of the way. Endpoint servers (anyone can make these) define their own meaning: • a swipe might open a door • dispense candy from a gumball machine • turn on the lights • acknowledge a request • dispatch assistance • mark a work zone active • start workflows in systems you already use Messages are signed by default using per-service cryptographic keys so endpoint operators can verify where events came from. If you're developing your own service, you can ignore these signatures while prototyping and later lock it down by recognizing signatures from trusted devices only. This is how you make sure only you or people you authorize are allowed to operate your service. Sweepline works well with: • self-hosted servers • Raspberry Pi projects • volunteer shift tracking and informal help requests • pickup sports availability and score tracking • formal or informal clock-in/clock-out • maker-space infrastructure • studio and workshop lighting and controls • interactive art installations The protocol is intentionally small and open. The goal is deliberate, low-friction signaling across independent systems. Sweepline carries the gesture. Endpoints make the move.
