Convert Experiences vs GrowthBook

Convert Experiences compared with GrowthBook

Both take statistics seriously and both publish methodology, but they serve different sides of the building. GrowthBook is developer-side, warehouse-native, and $40 per seat, testing what happens inside an application. Convert is marketing-side with a visual editor, 40-plus targeting filters, and a QA layer, at $299 a month. A marketer testing landing pages should take Convert; a product team testing features against warehouse data should take GrowthBook. Companies with both problems often run both.

GrowthBook compared with Convert Experiences

Convert Experiences is a marketing-side CRO platform with a visual editor, priced from $299 a month billed annually for 100,000 tested users. GrowthBook is a developer-side experimentation platform priced per seat with a far deeper statistics engine. A marketing team testing landing pages without engineering should use Convert; a product team testing in-app changes with warehouse data should use GrowthBook.

Convert Experiences

Subscription metered on tested users per month, meaning visitors actually entered into an experiment, with tiers differing on test types, active projects, domains, and support.

Convert is expensive next to the testing bundled into heatmap tools and cheap next to enterprise experimentation platforms, which is exactly the gap it is built for. Working out the bill is easier than usual because the meter counts only visitors entered into an experiment. A site with 10,000 monthly users running one test at 50 percent traffic allocation consumes around 5,000 tested users a month, so it sits inside the 100,000 allowance many times over and pays $299 for capacity it will not use. A site with 100,000 monthly users running several concurrent tests across most of its traffic will approach or exceed the allowance and should price the Enterprise band. That shape means Convert is poor value for occasional testing and good value for a busy programme, and the break-even point is roughly whether you run more than one test at a time, every month, all year. What you get above cheaper alternatives is statistical machinery that holds up under scrutiny, sequential testing, sample ratio mismatch detection, named bandit algorithms, outlier handling, plus a QA layer and a privacy posture that survive a compliance review. If nobody in your organisation will ever question a test result, you do not need any of it.

GrowthBook

Per-seat subscription on cloud with a free tier, plus a free unlimited-user open source self-hosted edition and quoted Enterprise plans on both. Usage charges apply only to CDN delivery and the optional Managed Warehouse.

Judged on statistics per dollar, GrowthBook is the best value in this category by a wide margin: sequential testing, CUPED, proper Bayesian inference with configurable priors, multiple testing corrections, and six automatic data quality checks are all present on a free tier. Judged on total bill, it depends entirely on headcount. Because the meter is seats rather than events, traffic volume barely matters: a product with 10,000 monthly users and one with 100,000 monthly users both cost the same, which is either a bargain or an irrelevance depending on your shape. A five-person team on Pro pays $200 a month; a twenty-person team pays $800, which is where the free self-hosted build with unlimited users starts to look attractive if you have the operational capacity. Against Statsig, whose free tier is enormous and whose statistics are comparably sophisticated, GrowthBook wins on warehouse-native architecture and auditability and loses on out-of-the-box analytics. Against Flagsmith or Unleash it costs more and does far more.
