Stop guessing.
Deploy winning tests faster.
Foretellr is the Intelligence-First experimentation platform for Growth Architects. Run statistically rigorous A/B tests with Bayesian statistics, zero-flicker edge delivery, and smart audience targeting.
Features
Intelligence-First Experimentation
Traditional tools give you a blank canvas and fragile code. Foretellr acts as your Optimization Partner, handling the heavy lifting from hypothesis to execution.
Smart Audience Targeting
Target the right users with precision. Filter by URL pattern, device type, browser, and custom attributes sent from your app — then let Foretellr deliver the right variation to the right audience.
Bayesian Statistics
Go beyond p-values. Foretellr calculates the probability each variation will be the winner, with credible intervals, so you can call experiments early with confidence.
Webhooks & Integrations
Push experiment results to Slack, your data warehouse, or any tool in your stack. Outbound webhooks fire on key events so your whole team stays in the loop.
{ "event": "experiment.completed" }
High-Load Edge Computing
Traditional SDKs cause flicker and harm Core Web Vitals. Foretellr runs on Cloudflare Workers. Decision logic, hashing, and targeting happen at the edge, delivering variations with sub-50ms latency.
Transparent pricing for scale
Usage-based pricing aligned with your Monthly Tracked Users (MTUs).
