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

With Insomnia you can:

- **Debug APIs** using the most popular protocols and formats.
- **Design APIs** using the native OpenAPI editor and visual preview.
- **Test APIs** using native test suites and collection runner.
- **Mock APIs** using a cloud or self-hosted mocking server.
- **Build CI/CD pipelines** using the native Insomnia CLI for linting and testing.
- **Collaborate with others** using the many collaboration features.
- **And more** including the ability to use 3rd party plugins.

The following storage options are supported for your Insomnia projects, collections, design specs and all other resources:

- **Local Vault**: for 100% local storage of collections, design specs and every other resource.
- **Git Sync**: for Git storage using any 3rd party Git repository, without going through the cloud.
- **Cloud Sync**: for cloud collaboration, optionally end-to-end encrypted (E2EE) in the cloud.

## Get started for free

Insomnia is available for Mac, Windows, and Linux and can be downloaded from the website:

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.

## Premium features and support

Insomnia has a very generous free plan that will be satisfactory for most users, but if you need to get access to premium capabilities like unlimited collaboration, the Git Sync fe
