Buy — $997
for Ecommerce

Ad attribution for stores that keeps every sale.

Buy the licence — $997 See what it does

Order webhooks in, revenue per campaign out. A rebill or a refund carries a pointer back to the purchase that started the relationship, so lifetime value credits the ad that found the customer — not the ad that happened to be last.

How it works

How it works

Ad platforms miss a lot

Safari caps third-party cookies at seven days and each platform sees only its own clicks. The sale that started on Meta and closed on Google is claimed by both or by neither.

Open Attrib closes the gap

A first-party tracker on your own subdomain, plus your Stripe or WooCommerce webhook: every sale, tied to every click that led to it.

It sends the sale back

Server-side to Meta CAPI, Google Ads and TikTok Events, hashed, once per platform, retried on failure and never doubled.

You scale what actually sells

Spend and revenue joined per campaign per day. ROAS under five models in the P&L page of your own instance.

Every order joined to the click that earned it

and the ad spend that paid for it.

Spend, revenue and ROAS per campaign, on your own box

Orders

Stripe and WooCommerce webhooks with verified signatures. The upstream event ID dedups replays, so a webhook retry is never a second order.

Repeat customers

A subscription rebill points at its root purchase. Credit is measured from there, so a renewal eight months after the click still credits the click.

Your own numbers

No network data, no modelled revenue. The dashboard shows what your webhooks reported and what your ad accounts spent — nothing else.

Run it in minutes

Yours to run, $997 once.

One command install

Five lines, one of them a text editor. Postgres, migrations, API, worker and TLS come up together — and the install help that comes with the licence is a call, not a document.

curl -O https://openattrib.com/openattrib-src.tar.gz
mkdir openattrib && tar -xzf openattrib-src.tar.gz -C openattrib
cd openattrib
cp env.example .env && $EDITOR .env
docker compose up -d

Nothing to migrate

Keep the pixels you already run. Open Attrib's tracker sits beside them on your own subdomain and records what they miss; the ad platforms get their conversions back server-side.

Recap

Let's recap

  • Stripe and WooCommerce webhooks record the sale and who bought.
  • The identity graph joins the buyer to every click they made.
  • Five models split credit; spend sync turns it into ROAS per campaign.
  • Confirmed sales are sent back to Meta, Google and TikTok server-side.
