What Koryla is
Koryla is a paid web testing service for A/B experiments at the edge or inside React, Vue, and Astro components. Its middleware intercepts HTTP requests and rewrites them to a selected variant before HTML is generated. An SDK resolves variants server-side for testing individual components. Koryla says integrations need no client-side JavaScript, script tags, or external CDN. Visitors remain assigned to the same variant for 30 days. Teams can define a conversion URL and track impressions, conversions, and conversion rates per variant in real time. Listed analytics destinations include Google Analytics 4 Measurement Protocol, PostHog, Mixpanel, and webhooks. Integrations include Next.js, Nuxt, Astro, and Netlify. Plans start at $12 a month; Starter allows 2,000 impressions, five experiments, and five team members. There is no free plan, visual editor, or mobile SDK.
