About BYN prices in USD/EUR/RUB
BYN prices in USD/EUR/RUB
Belarusian marketplaces price everything in Belarusian rubles, and comparing an offer on one site with an offer on another means reaching for a converter every time. This extension does it for you: every BYN price gets its equivalent printed right underneath, on every page you already visit.
For comparison only
The converted figures are there to help you weigh one offer against another across different platforms. They are a reference, nothing more: every listing is priced in Belarusian rubles, and every deal, payment and agreement is made in Belarusian rubles. Rates move daily, so treat a converted price as a guide to roughly what a listing is worth, never as the amount anyone is asking.
Where it works
Catalogue items on catalog.onliner.by, and the classified listings on onliner.by and kufar.by.
Property, for sale and to rent, on onliner.by, kufar.by, realt.by and flatby.by — including the price per square metre where a site shows one.
Cars and other vehicles on onliner.by, kufar.by, av.by and abw.by.
Search results, ad pages, cards in a map popup and the totals a booking form works out are all covered. Where a site offers currencies of its own, the prices it writes in Belarusian rubles are the ones converted.
Currencies
Pick any number of the following, in any order, from the extension's button in the toolbar; the order you arrange them in is the order they appear in beside a price. The following currencies are supported: USD, EUR, RUB, BYN, UAH, PLN, CZK, HUF, RON, MDL, GBP, CHF, NOK, SEK, DKK, ISK, RSD, MKD, BAM, ALL, TRY, GEL, AMD, AZN, KZT, UZS, KGS, TJS, TMT, AED, SAR, INR, CNY, JPY, THB, IDR, AUD and CAD.
Exchange rates
Rates come from the Frankfurter API, which publishes the European Central Bank's reference rates. The ECB updates them once per working day at around 16:00 Central European Time, and they do not move again until the next publication — Friday's rates still stand on Sunday.
The extension refreshes shortly after each publication, between 17:15 and 17:30 CET, and keeps the result in your browser. Everything you browse after that reads those stored rates, so ordinary browsing makes no requests at all, and prices still convert if you go offline.
Frankfurter was chosen because it answers from anywhere. The National Bank of Belarus publishes its own rates, but that service is not reachable from every country, so prices would stop converting the moment you travelled or switched on a VPN. Here they keep working wherever you browse from.
Part of the page
Nothing to switch on, click or hover over: open a search page and the conversions are already on the cards, open a listing and they are under its price. Each one borrows the look of the price it belongs to — the site's own font, weight and colour, a little smaller and quieter so the original price stays the one you see first — and takes whatever room is going, on one line or stacked. Only the asking price is converted; monthly payments, loan ranges and "from N per month" offers are left exactly as they are.
Privacy
The extension talks to one address, the rates API, and asks it only for exchange rates. It sends nothing about you, the pages you open or the prices you look at. Your settings and the latest rates are stored in your own browser, and nowhere else.
