Optibase: Beyond A/B Testing - Run A/B, split, and multivariate tests directly in Webflow

Optibase is now more than an A/B testing tool. With this launch, teams can run experiments, personalize content, and see how users behave using heatmaps and recordings. All in one platform, built to be fast and easy to use. Learn what works, fix what doesn’t, and make confident decisions without complex or expensive tools.

Hey Hunters, it's Luka from Optibase. Optibase started as a simple way to run A/B tests. Over time, we noticed something important. Teams were running tests, but they still struggled to understand user behavior and act on results with confidence. So we expanded the product. This launch is about turning Optibase into a complete experimentation platform, not just a testing tool. Here is what is now possible with Optibase that was not before. 👨🏻‍🔬 Experiments: You can run A/B tests, split URL tests, and multivariate tests at different levels of complexity. From small copy changes to full page experiments, all in one workflow. 🎯 Personalization: You can now personalize content and experiences based on audience rules like location, device, traffic source, or behavior. This lets teams show the right message to the right users, not just test one version for everyone. 📊 Analytics: We improved how results are tracked and viewed. Teams can follow conversions, compare variants, and understand performance without digging through complex reports. 🔥 Heatmaps: You can see where users click, scroll, and focus. This adds visual context to your test results and helps explain why one variant wins. 📹 User recordings: You can watch real sessions to understand friction, confusion, or drop-offs. This helps teams move from guessing to knowing. The idea was not to add features for the sake of it. The goal was to cover the full loop, from experiment setup to understanding behavior to deciding what to ship next. If you have feedback or questions, I’m happy to dig into details.

@luka_mlakar Congrats on the launch! How opinionated is Optibase about experimental design?

Congrats on the launch! Optibase is a super clean way to bring serious, flicker-free experimentation and behavior insights to Webflow teams without the usual enterprise bloat.

Does this only work with Webflow? Can you push audiences to GA4 or other tools for deeper analysis? How many goals can you set up in a test?
Luka Mlakar

Great questions @kylepetz. Optibase works with any platform as long as you install the script. We started with Webflow and built a native integration there first, and now we’re expanding with native integrations for other platforms as well.

You can’t push audiences to other tools yet, but you can send test data to GA4, Mixpanel, HubSpot, and other tools. We also have an open API if you want to send results anywhere custom.

You can set up as many goals as you need within a test.

Congrats on the launch! Expanding from testing into the full experimentation loop makes a lot of sense, especially when teams struggle to act on results. How does Optibase help teams reconcile quantitative test outcomes with qualitative signals like heatmaps and session recordings when those insights point in different directions?

Luka Mlakar
@vik_sh Great question. We usually encourage teams to treat quant results as the “what” and heatmaps/recordings as the “why.” If a test wins but recordings show friction, that’s often a signal to iterate rather than ship blindly. Having both in one place makes those tradeoffs much easier to spot and discuss.

Wow, Optibase looks amazing! Love that it includes heatmaps and recordings right in the platform. How does the heatmap accuracy hold up with more complex single-page applications?
