Core API designing, debugging and collaboration. Unlimited collaborators for accounts with 1 project. Unlimited collection runs. Optional Addons. 1,000 free mock requests, then $10/25,000 reqs. 100 free AI Runner requests, then $20/10,000 reqs.
API Design Editor. Enable a design-first approach to API development with Insomnia's built-in specification editor. Instant Design Preview. Preview API designs instantly as you make changes without having to switch applications, or views. Automatic Validation.
Insomnia provides a way to test your APIs, all within the Test tab in Documents. Organize multiple tests under test suites and run them all at once. Unit tests in Insomnia rely on the Mocha framework, and Chai for assertions.
Insomnia is an API client that enables you to send API requests outside of your terminal, and without writing any code. This means you don’t have to write any finicky cURL requests or backend code to quickly retrieve information, push content to a database, and do anything else a given API enables you to do.
The Insomnia desktop application and related software packages are open source software under the Apache License 2.0 and the source code is available at github.com/kong/insomnia. The server-side software that backs the paid sync service is closed source.
Insomnia provides a number of authentication helpers to make it trivial to interface with the most common authentication standards. Choose your standard, fill in the prompted fields, and Insomnia will take care of the rest.
Create customized API test flows that provide deep validation of REST, SOAP, GraphQL, and GRPC APIs through custom Insomnia Test Suite scripts. Whether you are testing basic functionality or complex authentication flows involving OAuth 2.0 or OIDC, Insomnia has you covered.
