Optibase vs Convert: A/B Testing platform comparison

Optibase starts at $69/mo with a free tier for getting started. Convert starts at $399/mo with no free plan (only a free trial).

For marketing teams running client-side website experiments, Optibase delivers A/B testing, split URL testing, multivariate testing, personalization, heatmaps, and session recordings at a fraction of Convert's price.

Convert's higher price reflects its full-stack capabilities — server-side SDKs, feature flags, REST APIs, and advanced statistical engines. If your team needs those developer-oriented features, the price premium may be justified. If you're testing website content and layout, you're paying for capabilities you won't use.

Optibase: Native Webflow Designer app. Install from the App Marketplace, create experiments directly in the Webflow Designer, zero friction.

Convert: No native Webflow integration. Requires manual script injection via custom code or Google Tag Manager. Works, but requires more setup and isn't maintained as a first-class integration.

For Webflow teams, this is a decisive difference. Optibase is the only A/B testing tool built around the Webflow workflow.

Optibase includes heatmaps, scroll maps, and session recordings in the platform. See where users click, how far they scroll, and replay full sessions alongside your experiment data. No additional tools needed.

Convert does not include behavioral analytics. You'd need to add Hotjar, Clarity, or a similar tool separately — adding another subscription and fragmenting your optimization data.

This is where Convert stands out. Convert offers full-stack experimentation with server-side SDKs (JavaScript, Python, PHP, and more), feature flags, kill switches, REST APIs, and CI/CD integration. It's built for engineering teams running experiments in code.

Optibase focuses on client-side website testing with server-side conversion tracking. It's built for marketing teams running experiments through a visual editor without needing developer involvement.

Optibase uses a Bayesian engine (P2BB — Probability to Be Best) with auto-stop when a winner is detected. Simple, clear, and designed for marketers who need a reliable answer without configuring stats parameters.

Convert offers both Frequentist and Bayesian engines plus sequential testing (Asymptotic Confidence Sequences). More options for teams with statistical expertise, but more configuration required.
