A free Triple Whale alternative

Most people searching for a Triple Whale alternative want one of three things: a lower bill, something that isn't built around Shopify, or attribution numbers they can audit line by line. neo covers all three — by doing much less.

Narrower on purpose

neo is not a business-intelligence dashboard. There is no cohort analysis, no LTV modelling, no creative-fatigue scoring, no Slack digest of forty metrics. It answers one question: which ad produced this order, and can we prove it?

• ▸Any store, not just Shopify.Shopify has a dedicated HMAC-verified webhook, ClickFunnels has its own, and there's a documented generic webhook for anything else that can POST JSON. If your checkout can fire a webhook, neo can count it.
• ▸First-party tracking on your own subdomain, registered and SSL-issued automatically when you add it.
• ▸Observed and inferred are never mixed. Cookie match, hashed-email match, then a strict single-candidate time window. Probable matches show separately — 96 (+9), not 105 — and orders we can't place stay visibly unattributed.
• ▸Front-end vs upsell split, derived rather than configured: an order from an email that already bought in the previous 24 hours is treated as an upsell, and never collapsed into the original order.
• ▸aROAS — revenue after payment-processor fees, so the figure reflects what lands in the bank.
• ▸Server-side CAPI, deduped by order id.

Price

Free, every feature, no card. Fair use is 25,000 tracked events a month with a visible meter and early warnings; there's a hard 50,000/day safety cap so a runaway script can't bankrupt a free product. Both are on the pricing page rather than in a footnote, and if you cross them legitimately the fix is an email.

Reasons to stay with what you have

• ▸You want one dashboard for every channel. neo does Meta and email, full stop.
• ▸You need spend, blended ROAS and MER computed for you. neo doesn't ingest spend — that stays in Meta, and the comparison happens in Ads Manager via the Chrome extension.
• ▸You rely on forecasting, LTV or inventory features. None of that exists here and none of it is planned.
• ▸You need team seats and roles, or a vendor with an SLA.
• ▸You'd rather have a bigger attributed numberthan a smaller certain one. No fingerprinting means neo's matched count will be lower than tools that stitch identities probabilistically. That's the trade, made on purpose.

Running both

You don't have to choose to find out. The same order webhook can feed two tools, and CAPI events deduped by order id won't double-count against your pixel. After two weeks, compare the counted order totals and — the interesting part — ask each tool which of its conversions were observed versus inferred. If only one can answer, you've learned something about the number you've been scaling on.
