pingrb

pingrb is a tiny push notification app. Webhooks, monitoring alerts, and CLI pings from any agent or shell script turn into clean push notifications. No code to write. No services to host.

If it can POST, pingrb can push.

Built-in sources:
- Stripe (payments, refunds, disputes, subscription events)
- Cal.com (bookings, reschedules, cancellations)
- Hatchbox (failed deploys)
- StatusCake (site down, site up)
- Custom curl endpoint (anything that can POST JSON)
- pingrb CLI (Claude, agents, shell scripts, cron jobs)

How it works:
1. Sign in at pingrb.com (free).
2. Pick a source. Copy the webhook URL or curl command.
3. Pushes arrive on your phone instantly. Tap any push to jump to the source.

CLI install (free, Homebrew):
$ brew install ruby-native/tap/pingrb
$ pingrb "deploy finished"

One price, no subscription. Pay $9.99 once for unlimited pushes. No monthly fee, no per-notification cost, nothing to self-host.
