Loved by thousands of developers
Don't just take our word for it. Here's what some of our users have to say.
“We migrated away from Postman due to privacy concerns, as we do not want to store confidential data on external servers. Kreya was the perfect solution for our needs. With its local-first approach, we know our data stays within our network and under our control.”
“We chose Kreya for its powerful gRPC support and we particularly like the privacy-first approach. All data is stored locally, nothing leaves our network. Thanks to the Kreya Enterprise Offline license, the app works completely locally without an account. The intuitive and uncluttered interface of Kreya allows our team to execute and troubleshoot testing activities with great productivity and focus.”
