A/B testing for
smaller teams
We’re building Checkmango to help developers and smaller teams test changes to their applications.
We fund and build Checkmango ourselves.
Checkmango helps solo developers, agencies, and small businesses measure how their changes affect conversions.
Why we built Checkmango
Our experience at an online travel agency showed us the value of A/B testing, but the tools were often expensive and complicated.
We started building Checkmango in 2020 to make A/B testing more approachable for developers and smaller organizations. In 2023, we launched on Product Hunt.
Checkmango lets you manage experiments, feature flags, conversion events, and participant activity in one application. You build the variants in your own code, then compare the results to decide what to release.

Support your existing code
Use Checkmango in your frontend or backend with the PHP SDK, JavaScript SDK, or REST API.
Measure changes before releasing them
Compare variants and their conversion results before deciding which version to release.
Keep testing practical for small teams
We’re building A/B testing tools that small teams can use as part of their regular development work.
