Convert Experiences vs Optimizely (2026): which should you pick?

Pick Convert Experiences if

• Fits if you run A/B tests on a site with a team that can set them up
• Works for stores that test on Shopify

Look elsewhere if

• Pricey if you're small, at $299 to $399 a month with no free plan
• Watch out: overuse costs $399 per extra 100K tested users on Growth
• Tight if you test a lot, with 5 projects and 5 active experiences each
• Watch out: multivariate, full-stack and flags need Pro at $420
• Not for you if you want development help, as no plan includes it

Pick Optimizely if

• Fits if you run many tests a month and have a team to run them
• Works for a large company that wants experiments, flags and content in one vendor

Look elsewhere if

• Skip it if you want a price to look at, as nothing is published
• Not for you if you need a free plan or trial, because neither is listed
• Skip it if you are a small site that just wants simple page tests, as this is a platform
• Watch out: it's several products, so what a quote includes varies by which you choose

Convert Experiences

• There is no free plan; the entry price is $399 a month, or $299 billed annually.
• Overuse is billed: $399 per extra 100K tested users on Growth and $699 per 250K on Pro.
• Growth caps projects at 5 and active experiences at 5 per project; multivariate and full-stack testing need Pro.
• The pricing page says none of the plans include development support.

Optimizely

• No prices are published: every plan is individually packaged and quoted after the buyer describes their needs.
• Optimizely is a multi-product platform, so what a quote includes depends on which products are chosen.
• No free plan or free trial is listed on the plans page.
