One platform replaces the five-tool landing page stack. Pages, tests, translations, and analytics - connected, not stitched together.

FIG 01

Pages, tests, and locales in one list

Folder campaigns and see test visits, conversion rate, and translation flags in one table.

FIG 02

Bayesian readouts you can act on

Probability to win, expected lift, and risk of loss - publish when the readout is conclusive.

FIG 03

Translations flagged when source changes

Staleness detection marks locales that drifted after English updates, before they go live.

Build pages without a rebuild

Generate from templates or upload HTML. Ship campaign pages without a dev queue.

Staleness detection for translated pages

Source page changes now flag downstream translations before they go stale in production.

Setup, stats, and timeline sit in a full-height rail next to the conversion chart.

Frequentist readout alongside Bayesian

Compare both statistical models side by side when a test reaches decision threshold.

Ads from winning page variants

Generate display ad units in IAB sizes directly from live landing page content.

Common questions

No. Upload HTML or generate from a template. Tests run in the interface. Developers are optional for custom tracking only.
