What our clients say
Real feedback from e-commerce owners, buyers, analysts and agencies who trust JsonEngine with their data needs.
We had no idea how our prices stacked up until JsonEngine set up daily competitor monitoring across six retailers. The data drops into our Google Sheet every morning, and we adjust pricing before we open. Margins are up and we stopped guessing — exactly on schedule, every time.
Fast, accurate, and exactly the format we asked for. Couldn’t ask for more.
We sell across three marketplaces and were drowning trying to track competitor listings by hand. JsonEngine now pulls assortment, prices and stock status for our whole category every night and pushes it to a Google Sheet the team actually uses. Within the first month we caught two competitors quietly dropping prices on our bestsellers and matched them before losing the buy box. When one of the target sites changed its layout, they fixed the parser within a day without us even noticing a gap in the data.
We needed full supplier catalogs exported to compare assortment and stock levels before negotiating volumes. The CSV files came in clean and well-structured, and it saved my team close to a week of manual copy-pasting. Delivery took a day longer than I’d hoped, but the quality made up for it.
Needed a one-time export of ~40,000 SKUs to clean up our catalog. Delivered in Excel, deduplicated, ready to use. Painless.
Building our pricing policy used to be a spreadsheet nightmare. Now we get a weekly assortment-and-price feed from our three main competitors straight into our database via API. We spot their promotions the day they launch and react instead of finding out a week later. Genuinely changed how our category team works.
Solid competitor price tracking on a weekly schedule. The data is reliable; I just wish the dashboard view was a bit more polished. The raw exports are perfect though.
As an agency, reliability is everything — we resell this data to clients, so it can’t break. We’ve run competitor price monitoring and promotion tracking through JsonEngine for four of our retail clients over the past half year. The API integration was straightforward, the documentation made sense, and the few times a source site changed structure, the team patched it faster than we could escalate. Having a scraping partner we don’t have to babysit lets us focus on the analysis our clients actually pay us for.
They scrape competitor pricing across the EU and UK for us daily. Clean JSON, straight into our pricing engine via API. Set and forget.
Good value and good communication. We use them for monthly assortment monitoring across competitors. Results are consistent — nothing flashy, just dependable data that lands when they say it will.
Honestly the smoothest vendor experience I’ve had this year. Quote, test scrape, delivery — all quick.
We asked for review and rating data on a product category to understand customer sentiment before launching our own line. The dataset was comprehensive and well-organized. Took a couple of rounds to get the exact fields we wanted, but the team was patient and got us there.
Our buyers used to spend Monday mornings manually checking supplier sites for new arrivals and price changes. Now JsonEngine sends a structured stock-and-availability feed for all our key suppliers twice a week, flagging what’s new and what went out of stock. It’s freed up a genuine half-day per buyer, and the data has been accurate enough that we trust it for reorder decisions without double-checking. Would recommend to any procurement team buried in tabs.
Used them for lead collection from a few public industry directories. Got a clean, deduplicated list in CSV. Did exactly what we needed for an outbound campaign.
What sold me was the compliance side — they were upfront about only collecting publicly available data, which my legal team appreciated. Beyond that, the competitor price monitoring has been spot-on. We feed it directly into our weekly pricing review and it’s become the backbone of how we set our pricing policy now.
Quick turnaround on a full marketplace assortment export. Great quality, fair scope, no surprises.
Reliable monthly price monitoring across our top competitors. The data’s accurate and on time. Onboarding was a little slow at the start, but once it was running it’s been smooth ever since.
We needed to understand a new market before entering it — assortment breadth, price ranges, and which brands dominated each category. JsonEngine put together a one-off dataset pulling products and prices from the leading regional players, delivered in both Excel and a Google Sheet so different people on the team could work the way they preferred. It gave our strategy team exactly the lay of the land we needed, and it cost a fraction of commissioning a traditional market research report. We’ve since put them on a recurring monitoring plan.
