TL;DR
Littledata and WeltPixel Conversion Tracking both send Shopify conversions server-side to your ad platforms, and both put every destination in one price, with no per-destination charge. The difference is the pricing model. Littledata meters by order: $0.35 each on Flex, $199 a month on Scale with 1,500 included, $990 on Plus with 10,000 included [1]. WeltPixel is $39 a month flat with unlimited orders [3]. The two prices cross at about 111 orders a month. Below that line, Littledata is genuinely cheaper and you should know it. Above it, every order you add costs you more on Littledata and nothing on WeltPixel. There is also a detail buried in Littledata's own overage rates that matters if you are near the top of their Scale plan: Scale stays cheaper than Plus until roughly 14,900 orders a month, so the $990 plan is rarely the one to buy. We build WeltPixel Conversion Tracking, so read this the way you would read any vendor's comparison: check the sources, all of which are public pricing pages, and run the numbers on your own store.
The Two Pricing Models Sell the Same Thing Differently
Strip away the plan names and both tools do the same job: a browser pixel for on-site events, with the conversion itself delivered server-side from Shopify's own order data, carrying event IDs the ad platforms use to avoid double counting. Littledata has been on the App Store since 2017 and holds a 4.8 rating from 123 reviews [1].
What differs is how you pay. Littledata's Flex plan bills $0.35 per tracked order with no monthly minimum [1]. Scale is $199 a month with 1,500 orders included, then $0.15 per order to 3,000 and $0.06 beyond that. Plus is $990 with 10,000 included, then $0.03 per order to 50,000. WeltPixel Conversion Tracking is $39 a month at any volume.
One caution when you check these numbers yourself: Littledata's pricing page displays annual-billed rates by default, showing Scale at $159 and Plus at $792 [2]. Those are the prices when you prepay a year. The monthly rates, confirmed on their App Store listing where Shopify requires billing disclosure, are $199 and $990 [1]. Neither figure is wrong, but comparing another tool's monthly price against Littledata's annual one is a mistake their own page layout invites.
Every price in this article was checked on July 31, 2026 against the sources listed at the end. Littledata can change its rates at any time, so re-check them before you decide.
Where the Lines Cross: About 111 Orders a Month
Divide $39 by $0.35 and you get about 111 orders.
A store doing 60 orders a month pays Littledata $21 on Flex and would pay WeltPixel $39. At 100 orders it is $35 against $39, still in Littledata's favor. At about 111 orders the two lines meet, and past that they separate fast. Run the arithmetic on an illustrative store growing through the year: at 500 orders a month, Flex costs $175 while the flat plan is still $39. At 1,500 orders, Littledata's cheapest option is now Scale at $199. At 3,000 orders Scale's overage brings it to $424, and at 10,000 orders it reaches $844 [1]. The flat price has not moved.
The per-order model is not a trick. It is the honest shape of Littledata's costs, and at low volume it genuinely favors the merchant. But it means your tracking bill is a function of your success, and the month a campaign finally works is the month the bill jumps. A flat price inverts that: it is slightly too expensive for a very small store and progressively cheaper for a growing one.
Which Littledata Plan Is Cheapest at Your Volume?
Here is the part nobody publishes, including Littledata. Because Scale's overage rates are modest, $0.15 and then $0.06 per order, Scale undercuts Plus far beyond the volumes you would guess from the plan names. At exactly 10,000 orders a month, the volume Plus is sold on, Scale costs $844 while Plus costs $990. Work through the published rates and Scale remains the cheaper plan until roughly 14,900 orders a month [1]. The rates are Littledata's own; the arithmetic is ours.
If you are a Littledata customer reading this, that is a real saving of about $146 a month at the 10,000-order mark, and you should take it regardless of whether you ever install our app. If you are choosing between the two tools, the practical version of the point is simpler: whatever volume you are at, price Littledata on its cheapest applicable plan, not the one whose included-order number matches your store.
Nine Destinations vs Eight Misses the Point
Littledata publishes nine destinations, included on every plan: GA4, Meta, Google Ads, Microsoft Ads, Pinterest, TikTok, Klaviyo, Attentive, and Recharge [2]. WeltPixel covers eight: GA4, Meta, Google Ads, TikTok, Pinterest, Reddit, OpenAI Ads, and Klaviyo. Neither tool charges per destination, a pricing pattern we examined in our Elevar comparison.
Counting to nine and counting to eight tells you nothing, because only six of those destinations overlap. The decision is the difference lists. Littledata carries Microsoft Ads, Attentive, and Recharge. WeltPixel carries Reddit Ads and OpenAI Ads, the channel behind ChatGPT's advertising rollout. If Microsoft Ads drives revenue for you, that alone decides it: Littledata reaches a channel we do not. If you are testing Reddit or OpenAI ads, the same logic points the other way.
On the WeltPixel side, the purchase reaches all six server-side, sent once with a shared event ID so each platform counts the sale exactly once [3]. For the mechanics of why that pairing matters, see why you need both a browser pixel and a conversions API.
Trials, Free Plans, and What You Can Run Forever
Littledata offers a 30-day trial capped at 500 orders, and behind it every plan bills: Flex is free to install, but it charges from the first order [1][2]. A fine model, and worth knowing before you build a test around it.
WeltPixel's Discovery plan is free with no time limit and covers GA4 conversion tracking up to 100 orders a month. It is GA4 only; the ad platform integrations belong to WeltPixel's $39 plan [3]. For a small store that mainly wants trustworthy GA4 data, that is a permanent option. It also means the trial question inverts at low volume: under 100 orders you can run WeltPixel's GA4 tracking free indefinitely, while Littledata's $21 a month on Flex, cheap as it is, is still a bill.
Setup effort is comparable and modest for both. Littledata ships a no-code event editor [1] and adds headless and Hydrogen support on Scale [2]. WeltPixel is a no-code panel inside Shopify admin, with a setup checklist and per-platform status banners so you can confirm events are arriving before you rely on them. Neither requires you to build and maintain a Google Tag Manager container, the path we weighed in the server-side tagging comparison.
Where Littledata Is the Better Choice
Three cases where Littledata is the right pick, from its own published pages:
You are under about 111 orders a month and need ad platforms, not just GA4. Flex has no monthly minimum, so a 60-order store pays $21 for the full destination list. That is less than our $39, and if your volume is staying put, Littledata is the economical pick.
Microsoft Ads, Attentive, or Recharge carry real revenue for you. These are on Littledata's list and not ours. Install the tool that reaches the channels you pay for.
You run headless, or your stack depends on Segment. Littledata lists headless and Hydrogen support and a Segment destination on Scale [2]. We publish no equivalent, and a headless build needs tools that state their support for it.
Outside those three cases, the flat-price argument at growing volume is plain arithmetic, and the crossover sits low enough that most established stores are past it.

FAQ
Is WeltPixel Conversion Tracking cheaper than Littledata?
Above about 111 orders a month, yes. WeltPixel is $39 flat while Littledata's cheapest plan costs $175 at 500 orders and $199 at 1,500, climbing from there. Below the crossover, Littledata's per-order Flex plan is the cheaper of the two, and at very low volume it is meaningfully cheaper [1].
Which Littledata plan should a 10,000-order store choose?
By Littledata's own published rates, Scale at $844 rather than Plus at $990. Scale remains the cheaper plan until roughly 14,900 orders a month. Plus adds features beyond price, such as multi-store rollups, so there can be non-price reasons to upgrade, but on cost alone Scale wins at that volume [1].
Do Littledata and WeltPixel track the same platforms?
Six overlap: GA4, Meta, Google Ads, TikTok, Pinterest, and Klaviyo, all server-side in both tools. Littledata additionally covers Microsoft Ads, Attentive, and Recharge. WeltPixel additionally covers Reddit Ads and OpenAI Ads [2].
Can I switch from Littledata to WeltPixel without losing my data?
Yes. Conversion history lives in your ad platforms and GA4 accounts, not inside the tracking app. The switch is installing one app and removing the other: install WeltPixel, verify events on each platform, then remove Littledata so purchases are not double-counted.
Does WeltPixel have a free plan like Littledata's trial?
WeltPixel's free option is a plan, not a trial: the Discovery plan covers GA4 conversion tracking up to 100 orders a month with no expiry. Littledata offers a 30-day trial capped at 500 orders, after which every plan is paid [2].
If your store is past the crossover and you want conversions delivered server-side to every major ad platform at a price that does not change with volume, install WeltPixel Conversion Tracking.
