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:

https://insomnia.rest

 Account & Subscriptions

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.

 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 feature, the ability to create organizations for your projects, using a 3rd party IDP for logins (SAML, OIDC) and many other features, then you can explore the other subscription plans.

You can compare all subscription plans and get started for free.

 Why does Insomnia require an account?

Insomnia does not require an account if you decide to use the local Scratch Pad, but to access most capabilities of the product we require an account. Your account data is securely stored in compliance with ISO27001, SOC 2 Type II, ISO27018, Gold CSA STAR regulations and in accordance with our terms of service and privacy policy.
