About

Are bugs slipping through your QA process and frustrating your customers? Catching issues early shouldn’t mean overwhelming your team with time-consuming tests. With MuukTest’s AI-driven platform, growing engineering teams reach 95% end-to-end test coverage in just 3 months, delivering quality at speed. By leveraging AI, our QA experts rapidly design, manage, and maintain comprehensive E2E tests for web, mobile, and API applications on the MuukTest platform. Within 8 weeks, we deliver full regression coverage, followed by exploratory and negative testing to uncover hidden bugs and expand test scenarios. We also proactively identify and address flaky tests and false results to ensure the reliability of your tests. Testing early and often allows you to detect bugs in the early stages of your development lifecycle, reducing the burden of technical debt down the line.

About

Twinbay is a hosted API simulation platform for developers testing AI agents and applications that call third-party services. Its stateful API twins can return configurable responses and model conditions such as payment declines, rate limits, expired credentials, email bounces, and paginated results. Teams direct compatible SDK requests to a twin, create isolated environments for test runs, inspect request logs, and use the environments in development or CI. The catalog includes twins for services such as GitHub, HubSpot, Plaid, Resend, Klaviyo, Linear, NetSuite, and QuickBooks. Twinbay offers a free plan with limits on twin usage and environment duration, pay-as-you-go twin-hour billing, and an Enterprise option. It is designed for engineers who need repeatable tests of agent behavior without relying on live production accounts or shared provider sandboxes.

Pros from Real Users

Pros

  • The service has been working well. It is effective, the support staff are helpful, and we have definitely cut down on the manual testing required before a release.
  • We have outsourced all of our testing to Muuk now. They handle all of our manual and automated testing. As a small software company, this enables us to focus on our primary skill of development and partner with Muuk to do the testing
