A/B test any website in minutes.

0

Most teams don’t lose to bad ideas. They lose to slow tests, messy tracking, and weeks of “can engineering help?” Stellar fixes that by letting you run A/B tests on any website fast, with a tiny script and a no-code editor. You ship experiments in minutes, see results in real time, and stop guessing what works.

Item 1 of 2

Your growth team doesn’t need another dashboard. It needs faster wins.

A/B testing tools love to brag about features. Cool. Meanwhile you’re still stuck waiting on dev cycles, fighting page speed, and arguing over numbers.

Stellar takes a swing at the real problem: speed to experiment.

What Stellar is

Stellar (gostellar.app) is an A/B testing platform built for agencies and growth teams who want to ship experiments without turning every change into a sprint ticket.

You drop in a 5.4KB script. Then you start testing.

No drama.

Why teams switch

Here’s the deal: most “testing stacks” fail at the boring parts.

  • The snippet is heavy, your site slows down, and conversion lifts evaporate.
  • The setup turns into a mini data project.
  • Reporting feels like it came from three different products glued together.

Stellar pushes the opposite direction: small script, fast setup, results you can actually read.

The parts that matter

Launch experiments in minutes

Stellar leans on a no-code visual editor so marketers can change headlines, buttons, layouts, and sections without babysitting HTML releases.

That means more shots on goal.

Real-time analytics (built-in)

You shouldn’t need to wire five tools together to answer one question: “Did Variant B win?” Stellar includes analytics so you can track performance while the test runs.

Fewer tabs. Fewer fights.

AI-powered insights

When you’re running a lot of tests, the hard part isn’t clicking “start”. It’s spotting what changed behavior and what didn’t. Stellar adds AI-driven insights to help teams interpret results and move to the next bet faster.

Who it’s for

  • Agencies running experiments across many client sites
  • Growth teams pushing landing pages and funnels every week
  • Founders who want proof before they rewrite their whole site

Pricing note

Stellar offers a free tier up to 25k tested users. If you’re early, that’s enough runway to find your first real conversion lift without paying tuition.

The takeaway: if your testing program keeps stalling on setup, site speed, or unclear reporting, gostellar.app aims to make A/B testing feel like shipping - fast, repeatable, and ruthless about results.
