Storyblok native Experiments vs the Croct Optimize app, what's the real difference?
I saw Storyblok Labs announce native A/B testing and now I have two options on the table before committing budget: native Experiments or the Croct Optimize app we were already evaluating. I would like a feature-by-feature comparison, not vibes. What does each one actually do for experiment setup, variant assignment, stats, and targeting? We are a small team and dev time is the scarce resource

Here is the factual feature-by-feature breakdown (native Experiments / Optimize app):
- Experiment configuration: yes / yes
- Variant content authoring: yes / yes
- Variant assignment and bucketing: no / yes
- No-code implementation: no / yes
- Autonomy from developers: no / yes
- Built-in analytics and statistical engine: no / yes
- Audience segmentation and profiles: no / yes
- Data enrichment integrations: no / yes
- Real-time personalization: no / yes
- Available on all Storyblok plans: no / yes
The practical difference behind the "no" rows: native Experiments lets you configure experiments and author variants, but it relies on custom code for variant assignment and on external analytics for measurement, so your developers build the bucketing logic and wire up the stats. The Optimize app includes a built-in Bayesian statistical engine, handles assignment and bucketing itself, and adds audience segmentation and profiles.
Given that dev time is your constraint, the assignment and analytics rows are the ones to weigh. A fuller writeup of this comparison is in the Storyblok native A/B testing vs Optimize app post.
Can confirm the assignment gap from experience. We trialed native Experiments when it appeared in Labs, and the part nobody budgets for is that "variant picking is your frontend code" means a real engineering project: cookie logic, sticky assignment, exposure events into your analytics tool, then building the significance math or a dashboard on top. Fine if you have an experimentation-minded eng team, a real cost if the whole point was letting marketing run tests. Ask whoever owns your frontend how many sprint days that is before comparing prices.
