Is there a free trial?

Yes. Every organization starts on the Free plan, no payment method required, with all features enabled. If you go over the quota, your visitors notice nothing and every analytics event is still recorded. Test results stop updating and your changes stop going live until the next month or a bigger plan. We email you at 80% and 100% so you can upgrade in time.

Can we use this in Shopify?

There is a no-code plugin in beta, however the API can be used to implement an integration in your theme.

How long do you store the data?

The only user data stored is form the analytics. This data sticks around while the corresponding test is in active or finished state. The moment a test is archived the results remain but the analytics get wiped, archiving a test is a one time operation. Test results will be kept around for as the organization exits.

Improve by the numbers.

A/B tests and feature flags for your site. Try an idea the same day, read the result at a glance and release without the stress.

Why Obelism Improve

Decide on numbers, not on hunches.

A/B tests give you hard data on what works for your customers. Feature flags let you ship big features in small, safe steps.

01 · Testing

Test your way.

Set up a test in the dashboard, ask the AI chat you already use, or give a Content block a second variant. Start measuring the same day.

02 · Feature flags

Release without the stress.

Ship big features in batches, hidden behind a flag. Turn them on per environment or for one audience, without preview links that run on other data.

03 · Results

See what’s happening.

Track page views, clicks and purchases, or send your own events. Every test shows the conversion per variant, the uplift and how sure it is.

04 · Audiences

Test on the right people.

Scope a test or a flag to a group of visitors: mobile users on Chrome, everyone on Windows, or one country.

But wait, there is more.

EnvironmentsDevelop, staging, production.Every organization gets all three, each with its own tests, flags and API tokens.
EventsYour own events.Send custom events to measure a test, or as a step in between to see where visitors drop off.
Server sideNo flicker.Pick the variant in Next.js middleware, so it is in the first HTML response.
API validationRequests that come from you.Domain checks for the browser and keys for the server, so every request is really yours.

How is Improve different?

It does one thing: giving you the tools to make your site better, with clear summaries and charts you can share.

const hero = useTestValue('warmer-hero')

return hero === 'b'
  ? <WarmHero roastDate />
  : <Hero />

// 2.1kb, minified and compressed

02Lightweight.The browser SDK is as small as we could make it: 2.1kb minified and compressed.
03Documentation.Get up and running with a getting started guide for Next.js, React, Hono and plain HTML.
