ItemPin vs Keepa vs CamelCamelCamel — Which Price Tracker Should You Use?
Ask "how do I check a product's price history" and you'll get the same two answers everywhere: CamelCamelCamel and Keepa. Both are excellent — if you shop on Amazon. The moment your cart lives on eBay, a regional marketplace, or a small independent shop, both go silent.
VKT ItemPin takes the opposite approach: instead of a cloud database of Amazon prices, it keeps a private, local price log for any product page you visit. This isn't a "which one is best" question — they solve different problems. Here's an honest comparison so you can pick (or combine) the right one.
Three Tools, Three Philosophies
- CamelCamelCamel is a website: paste an Amazon URL (or search a product name) and see the price history Amazon prices have passed through — sometimes years of it. The data lives on their servers and covers Amazon only;
- Keepa is both a website and a browser extension. It embeds rich price-history charts (price, used, third-party new, and more) directly into Amazon product pages, with alerting and deep analytics. Again: Amazon marketplaces only, data on their servers;
- ItemPin is a browser extension with no backend at all. You click "pin" on any product page — Amazon, eBay, a boutique store, whatever — and it records the price you see, with the date and currency, into a local chart. Your data never leaves your machine.
Think of it this way: CamelCamelCamel and Keepa answer "what has this product cost on Amazon?" ItemPin answers "what has this exact page cost me, over the weeks I've been watching it?"

When CamelCamelCamel Wins
- "Was this Amazon product cheaper last month?" — its years of accumulated Amazon history are unmatched. No local tool can tell you what happened before you started watching;
- "I want zero setup" — it's a website. Paste a URL, get a chart. Nothing to install;
- "I only shop Amazon, occasionally" — for a quick sanity check on a deal, it's the fastest tool around.
When Keepa Wins
- "I'm a heavy Amazon shopper" — the embedded charts on every product page, plus third-party-new and used-price tracks, give the deepest Amazon analytics;
- "I want to be told when the price drops" — Keepa's tracking and alerts run in the background, on their infrastructure. You don't have to remember to visit;
- "I hunt for the lowest third-party offer" — seller-level history is something no local log can replicate.
When ItemPin Wins
- "I shop outside Amazon" — eBay, regional marketplaces, designer outlets, small shops: pin any product page and the chart builds itself;
- "I don't want another account, and I don't want my shopping tracked" — ItemPin keeps everything in your browser's local storage. No sign-up, no sync, no server;
- "I compare across stores" — pin the same model at two or three shops, and the Premium comparison view overlays up to six products in one chart. Amazon-only tools can't even see those pages;
- "I want a log I control" — export to JSON, keep a backup, delete it whenever you like. Your history is a file, not a profile on someone's server;
- "I'm verifying a 'was' price" — during the weeks before a big sale, your own captures are evidence of what the store actually charged. That works on any shop, not just Amazon.
The Hybrid Approach (What Savvy Shoppers Do)
Here's the thing: these tools don't compete. A pattern that works well:
- Check CamelCamelCamel or Keepa for the long-run Amazon history — did this product ever actually cost more?;
- Pin the item with ItemPin everywhere you're watching it — including non-Amazon stores — and let the local chart accumulate;
- Before checkout, look at both: the server-side Amazon trend, and your own captured log.
One tells you the product's past; the other tells you what your stores have been charging you. Together they cover almost everything.

FAQ
Does ItemPin show prices from before I pinned an item?
No. A local price log only contains the points you captured yourself, so the chart starts the day you pinned the item. Keepa and CamelCamelCamel keep years of Amazon history on their servers — that depth is exactly what you trade away for privacy and store coverage.
Is Keepa free to use?
Keepa's core Amazon price-history charts are free to view, with some features reserved for a paid subscription. CamelCamelCamel is free and ad-supported. ItemPin is free for up to 50 locally stored products.
Which price tracker works outside Amazon?
ItemPin works on any website you can open in Chrome or Edge. Keepa covers Amazon marketplaces and CamelCamelCamel is Amazon-only, so neither can track a product page on a store they don't support.
Does ItemPin send my browsing or price data anywhere?
No. Captured prices live in the extension's local storage on your machine — no account, no sync, no server. Clearing browsing data deletes the log, so export a JSON backup from time to time.
