OSRS Wiki Live Prices

01What it does

The OSRS Wiki shows Grand Exchange prices, but those values are cached and can be hours — or days — out of date. This extension quietly replaces them with the live hourly average pulled from the official OSRS Wiki real-time prices API, and shows you how much each price has moved.

Always current

Prices come from the same real-time API the wiki itself uses, refreshed as you browse.

Shows the change

Wherever the wiki had a static value, you also see the delta — how much higher or lower the live price is.

Zero setup

No account, no options to configure. Install it and the prices just appear.

Private & tiny

No tracking, no background tasks. It only ever talks to the wiki and its price API.

02How to use it

Install the extension for Chrome (also Edge, Brave and other Chromium browsers) or Firefox.
Open any supported wiki page (see the list below). The extension recognises the page automatically — there is nothing to switch on.
Read the live prices. A moment after the page loads, prices are rewritten in place and a delta is shown next to each one.
Interact freely. Switching an item's variant, changing a money-making guide's kills/hour, or re-running a calculator re-injects the live prices automatically.

Prices are cached in your browser for about 5 minutes (item data for 1 hour) so repeated visits stay fast and gentle on the API. Nothing is stored anywhere except your own browser.

04Understanding the delta views

Wherever a page already showed a price, the extension keeps the original layout but swaps in the live value and appends the delta — the difference between the live price and the value the wiki had cached. That lets you see at a glance which way a price has moved, and by how much.

On money making lines: 1,284,000 | +96,500

On totals: 4,310,000 (−42,000)

The first number is the live value. The number after the | or in ( ) is the delta versus the wiki's cached price.
Green means the live price is higher than the wiki's value; red means it is lower. On profit figures, green is simply more profit.
Average price is the midpoint of the hourly high (instant-sell) and low (instant-buy) prices — i.e. (high + low) / 2. Items not traded in the last hour fall back to the most recent trade.
For profit calculations the 2% Grand Exchange sell tax (capped at 5M per item) is applied to outputs, so the numbers reflect what you'd actually bank.
A delta of 0 is hidden, so untouched values mean the live price already matched the wiki.

05Known limitations

A few things the extension deliberately doesn't try to price:

Spell & weapon-cast costs — e.g. a Death Charge or Dark Demonbane cast isn't priced.
Containers & grouped items — things with "underlying" items such as caskets, or a Yama Dossier, are left alone.
Custom wiki labels/logic on money making pages may not be recognised and are skipped rather than mis-priced.

06Privacy

The extension uses no browser-account or history APIs. It reads only the wiki page you're on and makes price requests to prices.runescape.wiki — the official OSRS Wiki real-time prices API. There are no analytics, no third-party servers, and no data leaves your machine.
