↗️ Create & Customize API Requests

• Create different types of HTTP requests (GET, HEAD, POST, PATCH, PUT and DELETE).
• Easily manipulate and play around with request inputs like headers, query parameters and body.
• Full support to send text content with 🥳 Unicode/Emoji and preview any API response containing Unicode/Emoji.
• Create GraphQL requests with headers and query.

💼 Organize Requests in Collections & Folders

• Create collections and folders to organize your requests.
• Press and Drag to Re-arrange requests.
• Click and open popup menu to rename, duplicate and delete a request.

🔎 Visually Preview and Download Data & Multimedia API Responses

• Inspect the API Response (HTTP status code, error message, headers, body, time taken).
• View formatted code previews for responses of various content types like JSON, XML, YAML, HTML, SQL, etc.
• API Dash helps explore, test & preview Multimedia API responses which is not supported by any other API client. You can directly test APIs that return images, PDF, audio & more. Check out the full list of supported MIME types/formats here.
• Save 💾 response body of any mimetype (image, text, etc.) directly in the Downloads folder of your system by clicking on the Download button.

👩🏻‍💻 Code Generation

• We started out as the only open source API client which supported advanced Dart code generation to easily integrate APIs in Dart/Flutter projects or to directly run it on DartPad. With time we have added more code-gens and currently API Dash supports generation of well-tested integration codes for JavaScript, Python, Kotlin & various other languages. You can check out the full list of supported languages/libraries.

🌙 Full Dark Mode Support

• Easily switch between light mode and dark mode.

💾 Data

• Data is persisted locally on the disk. To save the current snapshot, just press the Save button in the collection pane.
• Click and open the collection/folder popup menu to export it as HAR. This can be version controlled & can be directly imported in other API Clients like Postman, Paw, etc.
• Export your entire data into a HAR (HTTP Archive) file. To access this option goto Settings > Export Data.

⚙️ Settings & Other Options

• Customize various options using a dedicated Settings screen.
• Window Configuration (Size & Position) is persisted and restored on app start. (Only macOS & Windows)

AI Requests

API Dash lets you test AI APIs of various providers (or your own).

DashBot

Dashbot is the AI assistant available in API Dash (powered by local or cloud LLM) so that you can interact with your requests to debug it, generate code, generate doc, and many more.
