Your product
has a pulse.
Webhooks from Stripe, GitHub, your waitlist, your cron jobs — turned into native Mac notifications you can actually feel. No Slack workspace of one. No fifth dashboard.

The problem
You don't need another inbox.
You need a heartbeat.
Every tool wants its own dashboard. Every notification wants its own Slack channel. Solo founders end up with a graveyard of tabs and a Slack workspace of one.
Without Blood Rush
The graveyard.

That's it. One pulse. You feel it. You move on.
How it works
Three steps. Then you feel it.
◐
01
Add a Source
One per tool. Each gets its own webhook URL — no accounts, no Slack, no auth dance.
↘
02
Wire it up
IFTTT, Zapier, n8n, raw curl, your own script. Anything that can POST JSON can fire a pulse.
✦
03
Feel the pings
Native macOS notifications. A heartbeat in your menu bar. Last 50 events kept on your Mac.
Webhooks in. Mac pings out.
One curl is all
it takes.
Send any JSON to your secret webhook URL. Blood Rush normalizes the payload,
picks a sound, and pings your Mac. No SDK. No client library. Templating is
built in — write
{{email}}
and we'll wire it up.
~/projects/fond
$ curl https://api.bloodrush.app/hook/wl_8f3K… \
-H "content-type: application/json" \
-d '{ "title": "New signup",
"body": "marie@example.com",
"urgency": "rush" }'
{ "ok": true, "id": "evt_a04xQ" }

What's inside
Tiny app. Sharp edges.
Per-source rules
Every pulse gets a personality.
Sounds, colors, urgency, quiet hours, grouping. Stripe sounds like money. A renewal sounds like routine.

Quiet Mode
One-click 1h, today, until tomorrow. Or a schedule that breathes.

Templates
Per-event title, body, sound. Use
{dot.path} to pull any field from the webhook payload — or ship raw {title, body} via the custom hook.
Vitals history
Last 50 events, locally cached.
Searchable. Replayable for testing. Filter by source, urgency, or "the one with that email I half-remember."
Native, not Electron

Your event log lives on your machine.
Our backend is a thin relay. We see envelopes, not contents. Events expire from our servers within minutes.
Sources
The 5 we ship.
Stripe, Polar.sh, Lemon Squeezy, Dodo Payments, and Creem — each with native presets, sensible default copy, and a sound that fits. Anything else? POST JSON to the custom webhook and it works.

FAQ
Which payment processors work today?
Stripe, Polar, Lemon Squeezy, Dodo Payments, and Creem all ship as native presets — paste your webhook URL, drop in the signing secret, done. Anything else? POST JSON to the generic webhook and it works.
Is this just IFTTT for my menu bar?
Kind of. IFTTT and Zapier are great at piping events. Blood Rush is the surface they pipe into. We don't replace your automations — we give them a home.
Why not just a Slack channel?
Slack is a workspace. It wants threads, mentions, channels, "okay thanks." Blood Rush is a heartbeat. It pings, you feel it, you move on.
What about Windows or Linux?
Mac first. The bar is high — native Swift, real notification permissions, menu bar polish. We'll consider other platforms when v1 ships.
Where does my event data live?
On your Mac. Our backend is a thin relay; events expire from our servers within minutes of delivery. The full history sits in a local file you own.
Can I send my own custom events?
Yes. The generic webhook takes any JSON with title (required), plus optional body, urgency, and a click-through url. The source is whichever webhook URL you POST to.
What if my Mac is asleep?
Events queue on the relay. When your Mac wakes and reconnects, you get a quick burst of what you missed. No "you have 1,247 unread" drama.
When your product moves,
you'll feel it.
Free for one source, forever. €5/month unlocks unlimited sources.
