DynoWeb vs Convert
Convert is a testing tool with an unusually clear stance: first-party cookies, no personal data stored, GDPR and German privacy compliance, servers in Frankfurt. It also ships Shopify A/B testing specifically — so unlike most of this list, it overlaps with the storefront on purpose. The difference is still the same one: Convert runs the experiment, DynoWeb decides what is worth running.
What each product is actually for
DynoWeb
DynoWeb is conversion rate optimization built for one platform. It reads your storefront as a store — products, variants, cart, checkout, order value — and every insight it surfaces comes attached to a change you can preview and apply, with the revenue delta measured afterwards.
Convert
Convert bills itself as a 'proven A/B testing tool' that is 'reliable and affordable', reporting 40,000 sites optimized over 15 years. It covers A/B and multivariate testing, full-stack experimentation, personalization, feature flags and rollouts, a headless API, and Shopify A/B testing specifically. Its privacy position is a stated differentiator: first-party cookies, no personal data storage, GDPR/TTDSG/BDSG compliance and carbon-neutral servers in Frankfurt. It is popular with CRO agencies.

Who each tool is genuinely best for
Convert is the better choice for a real set of teams. If you are one of them, we would rather you knew now than after a trial.
Choose DynoWeb if
- Stores without the traffic for a properly powered page test
- Merchants who want the change made rather than a variation to build
- Teams with no CRO specialist to design and read experiments
- Anyone whose questions are about carts, variants and checkout
Choose Convert if
- Teams that genuinely need page-level A/B testing — DynoWeb does not do this and Convert does it on Shopify
- Anyone with strict GDPR or German privacy requirements, where the no-personal-data architecture matters
- CRO agencies running experiments across many clients
- Engineering teams that want feature flags and a headless testing API
- Stores with the traffic to reach significance in a sensible timeframe
Choosing between them — or running both
This is the clearest 'both' on the list. Convert has no behaviour analytics and DynoWeb has no page-level testing, so neither can replace the other. The sequencing question is which half you are missing: most stores have neither, and diagnosis usually pays first because it tells you what to test.
- Check your traffic. If a page test would take months to conclude, testing is not the constraint yet.
- Install DynoWeb and let it surface where the storefront leaks.
- Apply the changes that need no test — the plainly broken ones.
- When you reach genuine judgement calls, bring in Convert to settle them properly.
- If privacy compliance is a hard requirement, evaluate Convert on that basis specifically; it is a stated part of their design.
DynoWeb vs Convert, answered
Does DynoWeb do A/B testing like Convert?
No, not at page level. Convert runs A/B, multivariate and full-stack experiments including Shopify tests; DynoWeb has A/B testing only for SmartNudge variants. If you need to test two versions of a product page properly, Convert does that and DynoWeb does not.
Can I use Convert and DynoWeb together?
Yes, and this is the clearest 'both' of any comparison here. Convert has no behaviour analytics and DynoWeb has no page-level testing, so neither can replace the other. DynoWeb tells you what is worth testing; Convert settles it.
Which is better for GDPR compliance?
Convert makes privacy a stated design position: first-party cookies, no personal data stored, GDPR/TTDSG/BDSG compliance and servers in Frankfurt. If privacy architecture is a hard procurement requirement, evaluate them on that specifically — it is a real differentiator, not marketing.
Do I have enough traffic for Convert?
Check before you buy. Convert prices per monthly tested user starting at 100,000 a month, and experiments need statistical power to conclude. On a low-traffic store a page test can run for months without a verdict, which is the case for starting with diagnosis instead.

Stop guessing. Fix it and see the money.
Install DynoWeb, run it alongside whatever you have now, and compare the two on your own storefront rather than on a table.
