How it works
1
Paste a URL
Drop in any Shopify product or collection URL. Rivlr expands it, dedupes it, and starts watching.
2
We check on schedule
Price, stock, and variants polled daily, six-hourly, or hourly depending on your plan.
3
You get told
An email lands when a price moves or stock changes. Nothing else. Your inbox stays quiet.
Every price change, on the record
Rivlr keeps the full price history for every product you watch. See when a rival dropped, by how much, and whether they put it back up. Export the lot to a spreadsheet, decide your new prices, and update your shop.

How many they actually sold
Shopify shops do not publish sales figures. Rivlr works them out. Where a shop exposes its stock count we read it, and every drop is a sale, so you get numbers like 87 sold in the last 7 days rather than a guess. You also see the moment a rival runs out.

Find the products you should be stocking
Rivlr reads your rival's whole catalogue, not just the products you already share. Sort it by how many units are moving and you are looking at a shortlist of what to stock next, built from what is actually selling rather than what looks popular.

Common questions
How does it work, and is it legal?›
Yes. Rivlr reads the same public product data that Shopify stores publish for browsers, apps, and search engines every day. We respect rate limits, identify our crawler honestly, and stop tracking any store that asks us to.
Which stores can I track?›
Any Shopify store, anywhere in the world. That covers a huge share of direct-to-consumer ecommerce. Support for other platforms is on the roadmap.
Do I need to install anything?›
No. Rivlr runs entirely in your browser. There is no Shopify app to install, no code snippet, and the stores you track need nothing from you at all.
How fresh is the data?›
Daily on Free and Starter, and every 6 hours on Growth and Scale. Any product can also be refreshed on demand from its detail page.
Can I cancel anytime?›
Yes. Billing is monthly through Stripe and you can cancel in the app whenever you like. Access continues until the end of the period you have paid for, and your account drops to the free plan rather than disappearing.
What if I need to track hundreds of products?›
Scale starts at £49 for 250 products and you add as many 100-product packs as you need at £10 a month each, up to 2,500 in total. Past that, email us and we will build you a custom plan.
