    From the README

    Insomnia is an open-source, cross-platform API client for GraphQL, REST, WebSockets, Server-Sent Events (SSE), gRPC and any other HTTP compatible protocol.

    You can use Insomnia without an account with the local Scratch Pad, or you can create an account for free to get access to the full capabilities of the product.

    Even with an account, Insomnia only stores your projects and files accordingly to the storage backend that you have selected, which can be Local Vault, Cloud Sync, Git Sync or any combination of them. As such - for example - you have the freedom to choose to store sensitive projects 100% locally or in a Git repository, while still being able to collaborate on others in the cloud. It's the best of both worlds.

    For added security, Insomnia also offers a Private Environments feature, where your environments configuration is always stored locally and never in the cloud, independently from the storage option that you have chosen for your project.
