Watching one price,
or finding every price.
A price tracker watches one listing and tells you when it drops. Vesim looks across sellers for the same product and shows the cheapest one now. They answer different questions, and work well together.

About price trackers
What they do well.
Price trackers are browser extensions and websites that record the price of a product on a store over time, typically on one large marketplace or a set of supported stores. They draw a price-history chart, and send an alert when the price falls below a level you choose. Some also offer coupons or cashback, which can be how they are paid for.
01 02 Drop alerts
Set a target price once and get told when it is reached, without checking.
03 On the page you are on
As an extension, the chart appears right next to the product while you shop.
04 Deep on one store
Coverage of a single big marketplace can be very thorough.
Where Vesim differs
Four things on every answer.
What Vesim does that a tool built for a different job typically does not.
01 It looks across sellers, not across time
A tracker tells you whether this listing is cheaper than it was. Vesim tells you whether another seller has the same product for less, right now.
02 It matches the photo, not the title
Sellers rename the same product many ways but rarely change the supplier's photo. Vesim reduces each photo to a 64-bit fingerprint and treats listings within 10 bits as the same object, so renamed copies line up.
03 It shows the cheapest that fits
Your budget and where it ships from are gates, not hints. Anything that fails one is removed before sorting, and the cheapest of what is left is the answer. If a cheaper one failed, it says which requirement it failed.
04 It sells nothing
Vesim holds no stock, takes no checkout and sells no placements. Some outbound links may earn an affiliate commission, which is disclosed and never changes the order.
Try it
One listing, or every seller.
A real product from the index with more than one seller. Watch it the tracker way, one listing at a time, or the Vesim way, every seller of the same photo at once.

A tracker watches this one listing and alerts you when it drops. It is a good question, and Vesim cannot answer it yet: no price history has been recorded.
Real listings from the index, built from one catalogue of 376 products. Nothing in this demo is simulated.
Where Vesim is not yet better
The honest part.
What you give up by using Vesim today. Each of these is being worked on, and none of them is hidden elsewhere on the site.
01 No price history yet
Price history cannot be backfilled, and Vesim's first daily price check has not run. Charts and drop alerts come with Plus, which opens as a waitlist.
02 No alerts yet
Watching a price needs a daily price check, which has not started. When it does, free Vesim includes three alerts, and Plus makes them unlimited for $4.99 a month or $39 a year. Plus opens as a waitlist.
03 One catalogue today
Vesim is built to search millions of products. Today it searches one connected catalogue; the networks that bring thousands of stores each are on the way. Until they connect, its coverage is a small fraction of what large shopping tools cover.

When to use which
If you have already chosen where to buy and want to wait for a better price there, a price tracker is the right tool, and it has history Vesim does not have yet. If you want to know whether someone else sells the same thing for less today, use Vesim. Many people will use both.
Questions
What people ask.
Is Vesim a price tracker?
Not today. Vesim compares sellers of the same product right now. Price history and drop alerts arrive with the daily price check, as part of Plus, which opens as a waitlist.
Can I use Vesim with a price tracker?
Yes. They answer different questions: a tracker watches one listing over time, and Vesim finds other sellers of the same product. The Vesim extension checks the page you are on for other sellers.
Why can't Vesim show price history now?
Because history cannot be invented after the fact. It has to be recorded day by day, and Vesim's first daily price snapshot has not run yet. Vesim will not show a chart it did not record.
How much is Vesim Plus?
$4.99 a month or $39 a year. It opens as a waitlist, and nobody is billed until the daily price check is running.
