Everything a test needs, in one tab

Someone has to pick what to test, build it, put it live, and read the numbers honestly. That is usually four people and a month. Variant is one agent in your browser, and it starts on the site you already have.

01
Explore
Type in your site. Variant opens it beside the chat and reads its way through: home, pricing, product, checkout.
02
Propose
It hands you a set of tests at once. Each one says what to change, why it should move a number, and what counts as a win.
03
Preview
Click a variant and your real page changes. Click again and it is back. Nothing reaches a visitor.
04
Ship and measure
One script tag puts the test live. Variant calls the winner by a rule it cannot bend: a full week, enough traffic on both sides, odds that have settled.

Why it is different

Other testing tools live on their website and wait for yours to call them. Variant lives in your browser.

Nothing to install first

Every other tool needs its snippet on your site before you see a thing. Variant explores, proposes and previews on the site you have today. The snippet comes at the end, when there is a test worth running.

It sees what you see

Staging, localhost, the page behind your login: in your browser they are all just tabs. Variant asks before it opens anything private, and what it reads is summarised on your machine first.

What you previewed is what ships

The same code makes the change in the preview and on your live site. There is nothing to drift and nothing to rebuild by hand.

Pay for tested visitors, nothing else

Exploring and previewing are free, however long you spend. You pay for visitors who enter a live test, and you add a card when you get there, not when you sign up.

Questions

Do I need a developer?: Not to explore or preview. Putting a test live takes one script tag, once. The panel can send it to whoever deploys your site.
Can it break my live site?: No. A preview only changes the page in your browser and disappears when you reload. Nothing reaches a visitor until you start the test, and a test that goes over your limit pauses rather than breaking anything.
Which sites does it work on?: Any site you can open in Chrome: Shopify, Webflow, WordPress, a React app, a static page. Variant works from the rendered page, not the code behind it.
What happens to my data?: Pages are summarised in your browser first. Passwords, payment fields and customer details never leave it. Summaries are kept 90 days and never used to train models.
When is a test finished?: After a full week, enough traffic on both sides, and odds that have settled. The readout says which one you are still waiting on.
