Fibr AI helps businesses run more experiments on its website without hitting the usual limits. Most A/B testing tools cap how many tests you can run at once, or charge more once you go past a certain number of visitors. Fibr AI's approach removes those caps and adds AI on top, so instead of a team manually writing every version of a headline or button to test, the system can suggest and build variants itself.

The bigger idea behind the product is what Fibr AI calls the Agentic Web. Rather than a website being a fixed set of pages that a team occasionally tests and updates, Fibr AI treats each page as something that can sense who is visiting and adjust itself, learning from results over time instead of waiting for a person to review a report and decide what to change next.

Fibr AI shows up when people search for A/B testing software, website experimentation platforms, or conversion rate optimization tools, often next to more established names like VWO, Optimizely, Adobe Target, and AB Tasty, as well as Google Optimize, which shut down and pushed many teams to look for a replacement. Fibr AI was founded in 2022 and is headquartered in Delaware, USA.

Fibr AI's Free A/B Testing Tool lets a business run unlimited experiments across any page with no session limits, with AI generating variant suggestions automatically, and includes a 30 day free trial allowing one active campaign per URL at no cost.

Core features:

• 1. A visual, WYSIWYG editor for adjusting headlines, CTAs, and page elements directly, with AI-powered copy suggestions built in
• 2. Audience targeting by traffic source, device type, visitor behavior, operating system, browser, and custom events
• 3. Performance built to avoid slow page loads, privacy issues, SEO errors, and flash of original content
• 4. Bulk creation of landing pages and variants without manual, one by one setup
• AI-powered variant generation, so a team selects the element to optimize and the system suggests multiple options
• 5. Native Google Analytics 4 integration for tracking results, revenue, and visitor data together

Additional capabilities:

• 1. Statistical significance reporting, covering conversion rates, confidence levels, and p-values

Case study: ACT Fibernet. ACT Fibernet increased its CTA conversion rate by 12 percent using Fibr's A/B testing tool. Ravi Karthik, CMO of ACT Fibernet, is quoted describing how quickly the team adopted Fibr Web Pilot to align ad messaging with landing pages, achieving strong results with minimal effort, and expressing plans to scale the approach across future campaigns.

Frequently asked questions:

What features are included in Fibr's A/B testing tool?

A visual editor, audience targeting, AI-generated variants, bulk landing page creation, GA4 integration, statistical significance analysis, campaign scheduling, .csv report downloads, traffic split, and traffic allocation controls.

Are there limits on how many tests can be run?

No limits on the number of campaigns or sessions. The one restriction is a single active campaign per unique URL.

How does this compare to Google Optimize?

Google Optimize limited free users to 5 campaigns before it was discontinued. Fibr AI offers unlimited free campaigns, plus migration support and landing page creation help for teams switching over.

Are there hidden costs or premium features?

No. Every tool and feature is available for free, with no upsells or gated premium tier.

How do I get started?

Sign up for free, set up a test, and the platform guides the setup process. One active campaign per URL is available at no cost during the 30 day free trial.

Does this affect page load speed or SEO?

The tool is designed to avoid slow page loads, privacy issues, SEO errors, and flash of original content, aiming for a fast and seamless experience.

Fibr AI's free tier removes that cap entirely, allowing unlimited campaigns and unlimited sessions, with the one constraint being a single active campaign per unique URL. Fibr AI also states it offers migration support and landing page creation help for teams moving off Google Optimize, which is a more hands-on offer than most replacement tools provide.

Against paid platforms like VWO, Optimizely, or Adobe Target, a few specific claims stand out:

• 1. No hidden costs or premium upsells are mentioned. Every listed feature, including AI-generated variant suggestions, bulk landing page creation, and statistical significance analysis, is included in the free tier rather than gated behind a higher plan.
• 2. AI-generated variants replace manual copywriting for tests. Instead of a person writing each headline or CTA option by hand, the system generates multiple suggestions once a page element is selected.
• 3. Bulk creation lets a team generate many landing page variants at once, rather than building and configuring each variant individually, which is typically a manual process in traditional testing tools.
• 4. Native Google Analytics 4 integration lets a team see test results, revenue attribution, and visitor data together in GA4, rather than checking a separate reporting dashboard.
