Run flicker-free A/B tests that don't impact page speed — test pricing, algorithms, recommendations, and backend logic alongside frontend UX.
Client-side testing has limitations — page flicker, performance impact, and inability to test backend logic. Server-side testing solves all three, enabling experiments on pricing algorithms, product recommendations, search results, and application logic without any impact on user experience or page speed.
Step 1 of 2

Best fit for teams that need server side testing tied to revenue outcomes, cleaner reporting, and faster iteration across the funnel.
Built for companies that need server side testing executed consistently across content, technical work, launches, or campaign momentum.
Ideal for founders and marketing leads who want a sharper plan, cleaner deliverables, and straightforward accountability around server side testing.

These are the cro challenges we solve every day for businesses like yours.
Client-side testing causes visible page flicker — the original content flashes before the variation loads, degrading UX and biasing results.
Adding client-side testing scripts increases page load time — hurting Core Web Vitals and potentially decreasing conversion.
Pricing algorithms, search ranking, recommendation engines, and feature flags can't be tested with client-side tools.
Client-side tests expose variation logic in the browser — competitors can see your experiments and pricing tests.
Advanced front-end variations with dynamic content, conditional logic, and API calls are fragile in client-side editors.
Server-side testing requires engineering integration — without proper SDK setup, experiments are blocked by dev capacity.
