## Key takeaways

- The Wayback Machine can show what a public pricing page said on past dates, with gaps for pages blocked by robots.txt, behind passwords or built with JavaScript.
- Keepa and The Camelizer show price history for Amazon listings, and Chrome's Shopping Insights shows history and range for some products in five countries.
- AyeWatch watches any public store or pricing page you paste and sends a short summary when the price changes; paid plans start at $9 a month as of November 2026.

The right price history website depends on what you are about to pay for. For a gadget on Amazon, open Keepa or The Camelizer. For a SaaS pricing page that changed without a changelog entry, open the Wayback Machine. And for the next change on any page, a brand's drop or a plan table, set up [AyeWatch](https://ayewatch.ai) so the alert reaches you before the screenshot thread does.

## The cheat sheet

| You want to know | Open this |
| --- | --- |
| When the next price change lands on any public page | AyeWatch |
| What a pricing page said last spring | Wayback Machine |
| Whether an Amazon gadget deal is real | Keepa or The Camelizer |
| A product's price range across stores | Chrome Shopping Insights |

## 1. AyeWatch, for the next change on any page

Tech people buy from places marketplace trackers ignore: a keyboard maker's own store, a GPU from a specialist retailer, a dev tool's pricing table you are about to expense. AyeWatch reads a public page you paste and sends a short summary when the price, a tier or anything else you named changes. You write the rule like a sentence, for example "tell me if the Team plan price changes or a seat minimum appears", and AyeWatch checks the page against that rule.

Push and the in-app feed come with every plan. Paid plans add email, Slack, Discord and webhooks, plus a REST API and an MCP server if you would rather have your agent set up the watches. There is a free preview with no card, and paid plans start at $9 a month as of November 2026, billed in monitoring credits.

What it will not do: draw a chart of last year, read a price that only shows after login, or buy the thing for you. Your feed becomes the record from the day you add the page.

## 2. Wayback Machine, for what the page used to say

This is the closest thing to a price history website for pages nobody else tracks. Paste the pricing URL, press Browse History and pick a date from the calendar of captures. The number in the middle of an archive link is the capture time, written as year, month, day, hour, minute and second.

Gaps are normal. Pages blocked by robots.txt or behind a password are not archived, and prices rendered with JavaScript often break. Before a renewal, use Save Page Now to pin today's version: it stores one copy you can link to later, even after the vendor edits the page, but it does not schedule future captures.

## 3. Keepa, for Amazon gadget charts

Keepa's browser extension puts a price history chart on the Amazon product page and lets you set watches for a target price or a restock. Its listing covers ten Amazon storefronts, from .com and .co.uk to .co.jp and .in. If half your hardware budget goes through Amazon, this is the tab to keep.

## 4. camelcamelcamel's Camelizer, the lighter Amazon check

The Camelizer sits in the toolbar. Click the camel on an Amazon listing to see its past prices, or set a watch and get an email when it drops. It lists Amazon in the US, Canada, Europe and Australia.

## 5. Chrome Shopping Insights, already in your browser

On desktop Chrome, a Shopping Insights button in the address bar opens a side panel with a product's price history and range across the web, variants included. The fine print: be signed in, sync your history, and live in Australia, Canada, India, Japan or the US.

## What to bookmark

Keep the Wayback Machine for looking back and Keepa if you shop Amazon a lot. For the store pages and plan tables that change next, run [AyeWatch on any store page](https://ayewatch.ai/blog/any-website-price-tracker). If you never buy outside Amazon, Keepa on its own may be enough, and that is a fine answer.

## Frequently asked questions

### How can I see the old price of a SaaS plan?

Paste the pricing page URL into the Wayback Machine and press Browse History to pick an archived date. To hear about the next change, watch the page with AyeWatch.

### Is there one price history website for every store?

No. Keepa and The Camelizer cover Amazon, Chrome covers some products and the Wayback Machine has some pages. AyeWatch fills the rest by recording changes on any public page from the day you add it.
