About API Dash

API Dash is an open-source API client for desktop and mobile, built with Flutter and described as a lightweight alternative to Postman and Insomnia. You can create and customize HTTP and GraphQL requests, visually inspect the responses, and generate code for integrating an API into your application. It is released under the Apache-2.0 license and includes AI-assisted features.

Requests can be built with different HTTP methods, headers, query parameters, and bodies, and the app handles Unicode and emoji content in both requests and previews. Requests are organized into collections and folders that you can rearrange, rename, and duplicate. Collections can be imported from Postman, cURL, Insomnia, OpenAPI, and HAR files, and the topics also mention server-sent events and WebSocket support.

Builds are provided for iOS, macOS, Windows, and Linux in several package formats. It suits developers who want a free, native-feeling alternative for exploring and testing APIs and who may want to contribute, since the project takes part in open-source programs and welcomes contributors.
