As answered by people managing Mockaroo and FeedRobin.
FeedRobin's answer:
Two things. Feeds are rebuilt when a channel fetches them rather than on a schedule, so Google, Meta and the comparators read today's prices and stock rather than the last export — and if the store is unreachable, the last valid snapshot keeps serving instead of an empty file. And every channel and format is included on every plan at one flat price, so adding a comparator or a market is a decision about your catalogue, not about your bill.
FeedRobin's answer:
Three choices we made, which you can check before paying anything. The full feed check at feedrobin.com/audit is free, complete and needs no account or email — paste a URL and read the whole report. Pricing does not change when you add a channel. And no rule can rewrite a price: whatever the store says is what every channel receives, which removes the most common cause of a disapproval. If those matter to you, try the check first and decide from what it tells you about your own feed.
FeedRobin's answer:
Feed failures are silent. Products get disapproved, a cache serves an empty file, a price changes and the channel keeps showing the old one — and nothing alerts you until sales drop and you go looking. FeedRobin started as the tool to find that out early, which is why the check is free and needs no account: you should be able to see what is wrong with your feed before deciding whether you want anything from us.
FeedRobin's answer:
Small and mid-sized online retailers who advertise their catalogue, and the agencies that run shopping campaigns for them. It fits any store that can produce a public export — Shopify and WooCommerce natively, plus Magento, PrestaShop, BigCommerce, Ecwid or any CSV or XML — and it is aimed at merchants selling into several channels or countries at once, where a stale feed costs the most.
FeedRobin's answer:
Next.js and TypeScript, with Prisma over PostgreSQL. Feed syncing runs in a separate worker on BullMQ and Redis, so a slow store never holds up the app. Billing is Stripe; hosting is Railway.
