AdScale and Ralph are the two tools on our comparison table that are genuinely Shopify-native and genuinely read the store. That makes this the fairest fight on the site, and the difference is a philosophy, not a feature list.
Direct answer: AdScale is done-for-you: it builds Google and Meta campaigns from your store data and lets AI manage bids and budgets around the clock, from $169 a month with a 14-day trial. Ralph is show-then-ask: it puts variant-level stock next to spend, proposes dayparting, exclusions, product sets and titles, and writes only after you approve, from Free. If you want ads handled without looking, AdScale is the closer fit. If your losses come from ads paying for sizes you cannot ship and you want to stay in control, Ralph is.
Side by side
| AdScale | Ralph | |
|---|---|---|
| What it is | Shopify app that creates and runs Google and Meta campaigns with AI bid and budget management | Shopify operator desk: stock, Meta and Google in one morning list, actions staged for approval |
| Store data | Products, inventory, collections, orders (per its App Store listing) | Variants, inventory per location, orders, costs, catalogue identity |
| Inventory in decisions | Not documented beyond Merchant Center availability | Days of cover, core-size health, buffers, staged exclusions |
| Dayparting | None found | Meta: native schedule or stepped throttle. Google: recommend only |
| Automation model | AI acts continuously | Propose, approve, apply. Writers off by default |
| Creative | Agentic creative generation | Ad drafts in review, creative testing pushed paused |
| Pricing (seen September 2026) | $169 / $249 / $329 a month for $1K / $2K / $3K monthly spend caps; 14-day trial | Free £0; £99; £249; £599 a month; private beta |
| Reviews | App Store 4.7 across several hundred reviews | Not on the App Store; private beta |
The case for AdScale
You do not want to run ads. You want them run. AdScale has years of Shopify merchants, a high App Store rating, campaign creation on both big networks, and creative generation on top. For a small brand with steady stock and no appetite for Ads Manager, "install it and let it work" is a real proposition, and the spend caps on the public tiers suggest exactly that customer.
The case for Ralph
Your losses are not in bidding. They are in the ad that kept running after the size 12 sold out, the evening that looked weak because the shelf was empty, and the Monday you found out. Ralph exists for that join. It reads the variant, maps it to the catalogue item, computes cover and core-run health, finds the campaigns still paying, and stages the fix with the evidence. You approve. Free shows all of it; paid applies it. The mechanics are on how Ralph handles out-of-stock sizes and SKUs.
Where the two disagree
On who decides. AdScale's model is that AI should run the account. Ralph's model is that a human should say yes to anything that moves money, and that the writers should be off until that human turns them on. Both are legitimate. If you have been burned by autopilot, you already know which one you are.
On coverage. AdScale creates campaigns; Ralph does not build your prospecting structure for you. AdScale has creative generation as a headline; Ralph drafts copy for review and pushes tests paused. AdScale has no dayparting we could find; Ralph has it on Meta and recommends it on Google.
One tool runs the ads. The other stops the ads from running into an empty shelf. Most brands need one of those more than the other.
Honest caveats
AdScale's own site blocked automated reading when we researched this page, so its feature claims here come from its Shopify App Store listing and help centre snippets; check the current listing. Ralph is in private beta with a waitlist, not a trial you can start this minute. Neither fact should be hidden in a comparison.
Questions people actually ask
What does AdScale actually do?
AdScale is a Shopify app that connects your store and builds and runs Google Search, Performance Max, Facebook and Instagram campaigns with AI managing bids and budgets around the clock, plus creative generation. Its App Store listing asks for product inventory, collections and order history. Pricing seen September 2026: $169, $249 and $329 a month by ad spend cap, 14-day trial.
Does AdScale use inventory in its decisions?
Its listing requests inventory and variant data and its help centre talks about availability for Merchant Center, but we could not find documentation of stock levels or size runs changing an ad decision. Treat that as unknown rather than absent, and ask them directly.
Does AdScale daypart?
We found no dayparting feature. Its own blog says Advantage+ and Performance Max daypart implicitly and recommends Google's ad schedule bid adjustments for the rest.
Which is cheaper?
Ralph's Free plan is £0 and paid starts at £99 a month. AdScale starts at $169 a month for up to $1,000 of monthly ad spend. They are not buying the same thing: AdScale includes campaign creation and management; Ralph includes a Free tier that sees the leaks and a paid tier that writes after you approve.
Can I use both?
In principle. AdScale would run the campaigns and Ralph would flag where stock and spend conflict. In practice two tools writing to the same ad account is asking for confusion, so pick the one whose model you want and use the other's ideas.
If you want stock, ads and the morning list in one place: that is what we built Ralph for. A growth operator for Shopify, with review before anything ships. Not magic. Fewer tabs. See Ralph · Docs
