Our SDKs provide Swift experimentationSecured experimentationScalable experimentation
Build, test, and ship with confidence using our lightweight SDKs
PageSense SDKs give you the flexibility to define experiments and measure results—all without client-side scripts, without exposing test logic in the browser.
Built for flexibility
Whether you're testing a recommendation engine, tweaking a checkout API, or exploring the performance of features in your new app, our SDKs provide the structure you need to control all of the logic, traffic, and goal tracking.
Private by design
All experiment logic stays on your server. No client-side scripts, no exposed test variations, and complete control over user data and privacy compliance.
Fast to onboard
Get started in minutes with our intuitive SDK integration. Simple APIs, comprehensive documentation, and ready-to-use code samples for all major languages.

- Provide streamline configurations for testing environments, and maintain clean, independent setups
- Ensure consistency and control at every stage of rollout
Unlimited variations of your backend logic
- Create and manage unlimited variations across both frontend and backend layer
- Easily edit variation names and descriptions anytime
- Gain the flexibility to test and optimize every layer from experimenting with new UI layouts to refining backend functionality
Flexible traffic allocation & audience targeting
Define precise traffic proportions, target specific audience segments, and manage experiment distribution effortlessly
- Control traffic distribution between variations to fine-tune exposure and optimize testing accuracy
- Target specific user segments using your own custom-defined audience parameters
- Ensure consistent variation allocation for all users using MurmurHash-based assignment
Goal tracking & analytics
Measure performance accurately and make data-driven decisions with real-time insights.
- Define multiple goals for each experiment and set a primary goal to focus your optimization
- Track conversions directly from your server for reliable and precise data collection
- Access real-time analytics to evaluate variation performance and measure progress instantly
Real-time updates & instant reporting
Stay in sync and make faster decisions with seamless, real-time data flow between your SDK and PageSense.
- Get SDK updated instantly through webhook polling when settings or statuses change
- Maintain consistent, cookie-free variations for both new and returning users.
- Access real-time reports and analytics where user actions and conversions instantly reflect
Experimentation that fits your workflow
Run cohesive experiments across your stack. Whether conversions happen on your website, mobile, or backend services - track visitors and conversions across systems. Thus, making your releases test-safe and audit-friendly.
- Consolidate experiment data in one place, and access unified reports and analytics
- Coordinate testing across services without disrupting existing workflows
Stateless customizable SDK
Our SDKs don't rely on local storage or sessions, making them ideal for containerized and serverless architectures.
- Flexible options for custom logging, verbosity, and storage
- Enhance visibility, and ensure seamless integration within your application architecture.
A/B test experimentation, simplified
Deliver a seamless user experience without the complexity of client-side testing - absolutely no UI-layer bloat, performance hits, or enforced workflows.
- Prevent flicker and performance delays caused by client-side rendering
- Maintain complete authority over experiment logic, deployment, and performance
Experiment across teams. Deploy with control.

What type of tests are you planning to run?Backend Algorithms
Backend Algorithms
Test different recommendation engines, sorting algorithms, and business logic variations on the server side. Optimize your backend processes without any client-side exposure.
Pricing Tests
Compare different pricing strategies to maximize conversion and revenue without exposing test logic in the client. Run secure backend experiments on pricing models, discounts, and subscription tiers.
Layout Logic
Experiment with different page layouts, component arrangements, and UI structures controlled from the backend. Deliver personalized layouts based on user segments.
Content Personalization
Serve different content variations to different user segments. Test headlines, descriptions, and messaging to find what resonates best with your audience.
API Response Variations
Test different API response structures, data formats, and payload configurations. Optimize your API performance and user experience through controlled experiments.
Build what you want. Test what matters.
Experimentation should work like your stack does: fast, flexible, and fully in your control.
