A full-stack twin for every agent.
Each run gets its own MicroVM from a pre-warmed pool, so hundreds of agents test in parallel without touching production.
Learn moreEvery agent change, verified as it's written.
Karya gives coding agents an isolated digital twin of your stack and a self-maintaining testing suite. Your team reviews proof.
Works with the coding agents you already use
When people wrote the code, people verified the product.When agents write the code, agents should verify the product.
Karya gives agents what they need to verify their own work.

Common questions.
What kinds of applications do you support?
Karya supports N-tier web applications and standard HTTP and gRPC backends. Bring any infrastructure and our agents can map a digital twin of it.
What is a digital twin?
Think of it as a preview environment: a fully isolated, seeded, ready-to-use sandbox of your full application, including its dependencies, so agents are free to break and build as quickly as possible.
How is this different from an E2E test?
E2E tests typically run against a shared environment, such as staging, that carries state and can be affected by other people or agents in real time. Karya's digital twins are isolated, which allows massive parallelization with no side effects.
Can I try it out?
Yes. We offer a free tier where Karya scans your app and authors some initial test cases for you to try.
