Hover any price on any page and read it in your own currency. Chrome and Firefox, MV3, built with WXT and Svelte 5.
A price in a currency you do not think in costs a tab, a search box and your place in the page. PriceHover reads it where it sits. No account, no paste, one request a day for the rates.
- Hover or select a price. Your own currency comes first and is never converted away from.
$means what the site means.$49on a.cashop is Canadian,1 099 kron a.noshop is Norwegian,¥on a.cnshop is yuan.- Prose stays prose.
try 100 timesanderror code 500 KDare not prices. Every ambiguous token has a rejection test behind it. - Ranges.
€10 – €20,€10-20and10-20 krconvert as one range. - Click a row to copy the amount.
- Inline mode. Write your currency beside every price instead of waiting for a hover. It only ever appends.
- Two switches. A master one and a per-site pause, both in the popup.
- Rounding.
≈€1,235where€1,234.56would pretend to a precision a conversion does not have. - Sub-cent prices stay prices. A yen is
€0.0061, not€0.01, and never€0. Per-unit and prorated prices ($0.0075) are read too. - Crypto, if you want it. 24 assets including BTC, ETH, XMR, USDT, USDC and DOGE. Off by default, one extra host, granted by you and given back when you switch it off.
- 44 currencies, eight languages. Flags are bundled, nothing is fetched from a third party.
Note
2.0.0 changed how $ is read. On a country domain it now converts as that
country's dollar, not as USD. Settings → Behaviour → Read $, kr and
¥ from the site's country puts the old reading back.
The country comes from the domain, or from the region in <html lang> when the
domain says nothing. Vanity endings (.co, .io, .ai, .me, .tv, .to)
are ignored, because the country in them means nothing.

Off by default. The site's own text is never rewritten, only appended to, and
text fields, editable areas, code and pre are left alone.
Type 250 chf, 20 usd jpy, or a bare number to convert from your own
currency. The footer says how old the rates are and refreshes them on demand.
Your own currency, the list to convert into and its order, hover delay, rounding, inline mode and paused sites.
PriceHover contacts exactly one host, open.er-api.com, and asks it one
question: today's exchange rates. That request carries nothing about you or the
page you are on. Prices are detected on your machine, flags are bundled in the
extension, and there is no analytics, no telemetry and no identifier. Three
permissions: storage, activeTab and access to open.er-api.com.
Turning on crypto conversion adds a second host, api.coingecko.com, and
nothing else. It is off by default, your browser asks before granting it, and
switching it back off hands the permission back.

bun run typecheck # tsc --noEmit, kept clean and enforced in CIbun run icons, bun run flags and bun run locales regenerate committed
files and never run at build time. A release is cut by pushing a vX.Y.Z tag:
CI refuses a tag that disagrees with package.json, builds both targets and
attaches the zips.
Issues and pull requests are welcome. Keep bun test and bun run typecheck
clean, and never add a runtime request to a second host. Detection is the part
that breaks quietly: a token accepted one position too freely turns error code 500 KD into a price, so every new one arrives with the case that must stay
silent.
