Studio, engine and report.
Three parts, one goal: learn faster what works on your site, without making your site slower.
Studio
No-code and low-code in one editor.
You work on your real page. A new variant is a draft: visitors only see it once you click Publish.
Code tab
- Edit the HTML, CSS and JavaScript of your variant
- See the result right next to your code
- Handy if you like to fine-tune yourself
Each experiment has at most 4 variants live at the same time, and each page runs at most 5 experiments. That way every version gets enough visitors to tell you something.
Engine
A small script that stays out of your way.
One line of code
In the <head> of your site, or through Shopify, WordPress, Webflow or Google Tag Manager.
No flicker
Your visitor sees their version right away. Also works on sites that change pages without reloading.
Works with your cookie banner
Your banner passes on the choice. Without consent: show variants and only count anonymously, without a visitor ID. With consent: full measurement.
Report
A winner once the evidence is there. Not before.
Tessera compares every variant with your current page. A variant only wins when:
- every version has at least 50 visitors and 10 conversions;
- the test ran for at least 7 days, so every weekday counts;
- the chance that the variant does better is at least 99%.
Testing more variants at once raises the bar: 99.5% with two variants, 99.75% with 4. A variant that clearly does worse is flagged with the same rigour. Until then, the report simply says there is not enough data yet.
