Comparison
ProveLift vs Optimizely
Optimizely practically invented mainstream A/B testing and now sells a broad enterprise digital-experience platform, typically bought through a sales process with annual contracts. ProveLift is the opposite end of the spectrum: self-serve, priced for small and mid-size businesses, focused purely on experimentation — and it tests real product prices, which web experimentation tools can't.

Why teams pick ProveLift over Optimizely
No enterprise contract
Optimizely is typically an annual, quote-based purchase. ProveLift is a credit card and a snippet — running the same core web experiments the same afternoon.
Price testing built in
Optimizely's feature-experimentation SDKs could technically drive price changes, but it's a custom engineering project. ProveLift ships it as a product: pick a product, enter challenger prices, press start.
Statistics you can read
Guardrails hold a winner until runtime and sample thresholds are met, and SRM alerts flag broken tests — no statistician required.
The test Optimizely can't run: your price
Client-side testing tools change what a page looks like. ProveLift's store plugins change the real price a shopper is charged — applied server-side through WooCommerce, PrestaShop or Magento, consistent from product page to checkout, and judged on revenue per visitor. Pricing is usually the highest-leverage lever a store has, and almost nobody tests it.
How price testing worksWhere Optimizely is the better fit
A fair comparison cuts both ways — Optimizely is a strong product, and for some teams it's the right call:
- •Deep enterprise feature-flagging and experimentation SDKs for large engineering teams.
- •A full DXP: CMS, commerce and personalization products under one vendor.
- •Enterprise governance: roles, approvals, audit trails at big-company scale.
Frequently asked questions
Is ProveLift a full Optimizely replacement?
For web A/B testing, split-URL tests and e-commerce experiments — yes, at a fraction of the cost. It does not replace Optimizely's CMS, commerce platform or large-scale feature-flag SDKs.
Can developers still use an API?
Yes — ProveLift has a REST API, webhooks, and a server-side assignment endpoint for backend-controlled experiments.
What does ProveLift cost?
Plans are public and self-serve, with a free tier and paid tiers priced for SMBs — see the pricing page. No quote process.
