zeridion-flare

https://github.com/zeridion/zeridion

Synchronous Ruby client for the Zeridion Flare API (background jobs, recurring schedules, workers, webhook verification) plus an opt-in background-worker runtime (require "zeridion_flare/worker") that polls, dispatches to your job classes, heartbeats with progress, honors server cancellation, and drains gracefully on shutdown. Zero runtime dependencies — uses Ruby stdlib Net::HTTP only.
