An open-source, self-hosted system for timing cross-country meets with live results, RFID readers, rosters, and starting-gun hardware.

Landing page captured for the 2026-09-20 issue.
For
Cross-country meet operators and race-timing volunteers
Worth noticing
The stack supports concurrent races, LLRP RFID readers, starting-gun triggers, and public results.

Field notes

The documented deployment combines FastAPI, SvelteKit, PostgreSQL, and an nginx reverse proxy in a five-container Docker Compose stack. A demo meet is seeded during setup, and the homepage supplies a default operator passcode for local use. Hardware support is separated into optional modules: one watches a host trigger file for starting-gun events, while another connects to LLRP-compatible RFID readers and exposes per-antenna status.
