Questions before you start?

Have a question about your integration or plan? Ask us.

What can I test with Checkmango?

Test changes you can implement in code: a signup flow, a checkout step, or backend logic. Create two or more variants, choose a conversion goal, and compare how each version performs.

How do I connect my application?

Use a PHP or JavaScript SDK, or call the REST API from any language that supports HTTP requests. Your code enrolls participants, serves their assigned variant, and records conversions. You’ll need a developer to add the integration.

How do I choose a request allowance?

Estimate how many ingest API requests your application will send each month to record actions such as experiment enrollments and conversions. One visitor can generate several requests, so page views alone won’t tell you which plan to choose. The allowance renews monthly, even when you pay yearly. Contact us if you need help estimating your usage.

Can I try it before subscribing?

All plans include a 14-day free trial. You can cancel your subscription at any time from your organization’s billing dashboard.

Can I use feature flags without an A/B test?

Yes. Feature flags work independently of experiments. Give a flag a key, set it to enabled or disabled, and optionally store a value. Your application reads the flag through the API and decides which functionality to show.

When should I choose a winning variant?

A higher conversion rate alone does not establish a winner. Review the statistical results and allow enough participants and time for a meaningful comparison before making a decision.
