A no-code tool for running A/B tests on websites to improve conversions.

GoStellar is a lightweight A/B testing platform founded by Juan Chaher, designed to help marketing teams and agencies run experiments without engineering dependencies. The company differentiates itself through a minimal 5.4KB JavaScript snippet that claims to be 25x smaller than competitors like VWO or Optimizely, reducing page load impact while offering GDPR-compliant, cookieless tracking. Its visual editor allows non-technical users to create variants directly on live sites, with features like AI-assisted copy generation and dynamic keyword insertion.

While the company does not disclose revenue or funding, its blog content and G2 reviews (4.8 rating) suggest traction among SMBs and digital agencies. Recent focus areas include server-side testing architectures for privacy compliance and Bayesian statistical methods for faster results. The platform integrates with common CMS and e-commerce systems like Shopify, Webflow, and WordPress, positioning itself as a tool for rapid iteration rather than enterprise-scale experimentation.
