What Sematext Experience is
Sematext Experience analyzes real user sessions to reveal front-end performance issues and send anomaly alerts. It collects page-load times, HTTP requests, resources, UI interactions, and Core Web Vitals including Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift. Individual sessions can be reviewed in timeline or table views with page loads, transactions, and requests. Alerts support any performance metric and Apdex, with priorities and notification routing by alert type. Automatic anomaly detection identifies irregular performance spikes without manual rules. Experience combines front-end measurements with backend logs and monitoring data in one view for troubleshooting. URL Groups organize website sections, while custom measurements and thresholds focus collection on selected signals. It supports API and web access, lists React, Vue.js, Angular, and Ember support, and describes integrations with over 100 cloud providers. Team accounts, member roles, audit trails, and scheduled email reports support collaboration. The product offers a 14-day trial without a credit card. Annual Startup pricing is $8.10 a month for 25k views, while regular Startup pricing is $9 a month.
