What Our Customers Say
Real feedback from engineering teams using Stage every day
"Stage has completely transformed how we develop and test our APIs. What used to take days of manual setup now happens automatically. We've cut our API development time by 60%."
"The ability to create scenarios without touching production data is a game-changer. Our QA team can now test edge cases that were previously impossible to replicate."
"We were spending hours setting up mock servers for each sprint. Stage eliminated that entirely. Now our developers can focus on building features instead of infrastructure."
"Stage's scenario management lets us simulate any API state. We've caught bugs in staging that would have been disasters in production. It's now a critical part of our CI/CD pipeline."
"Integration testing used to be our biggest bottleneck. With Stage, we can spin up realistic API environments in seconds. Our release velocity has never been higher."
"The developer experience is phenomenal. Stage fits seamlessly into our workflow, and the documentation is top-notch. Onboarding new engineers takes half the time now."
