All-in-one API platform to design, debug, mock, and test with CI/CD
API Dash
Beautiful cross-platform API client with multimedia response preview
Open-source API client for creating, testing, and inspecting HTTP, GraphQL, and streaming requests with visual multimedia response previews and multi-language code generation.
Overview
Modern API Testing for Every Platform
API Dash is a cross-platform API client built for developers who need more than basic request testing. Available on iOS, macOS, Windows, and Linux, it combines intuitive request creation with advanced response inspection capabilities that go beyond traditional API clients.
Beyond Text Responses
Unlike conventional tools, API Dash natively previews multimedia API responses—images, PDFs, audio, and more—directly in the interface. It supports HTTP methods (GET, POST, PUT, PATCH, DELETE, HEAD), GraphQL queries, server-sent events, and AI endpoints. Organize requests in collections and folders, import from Postman, Insomnia, OpenAPI, cURL, and HAR formats, then export your work for version control.
Code Generation at Your Fingertips
Generate production-ready integration code in 25+ language/library combinations including Dart, JavaScript, Python, Kotlin, Rust, Swift, and more. Full Unicode/emoji support ensures international content displays correctly in both requests and responses. Data persists locally with manual save control, and dark mode adapts to your workflow preferences.
Highlights
Native multimedia response preview for images, PDFs, audio, and 50+ MIME types
Code generation for 25+ languages including Dart, Python, JavaScript, Kotlin, and Rust
Import collections from Postman, Insomnia, OpenAPI, cURL, and HAR formats
Cross-platform support: iOS, macOS, Windows, and Linux (multiple architectures)
Pros
- Unique multimedia response inspection unavailable in competing API clients
- Extensive code generation covering modern languages and popular HTTP libraries
- True cross-platform availability including mobile (iOS/iPad)
- Import/export flexibility with HAR, Postman, Insomnia, and OpenAPI support
Considerations
- WebSocket, MQTT, and gRPC support still in development
- Manual save required; no auto-save for request collections
- Hurl format import not yet supported
- Smaller ecosystem compared to established commercial alternatives

Fit guide
Great for
- Developers testing multimedia APIs (image processing, PDF generation, audio streaming)
- Teams needing multi-language code generation for API integration
- Mobile developers requiring iOS/iPad API testing capabilities
- Projects requiring open-source tooling with import/export portability
Not ideal when
- Teams heavily dependent on WebSocket, gRPC, or MQTT protocols today
- Organizations requiring enterprise SSO or team collaboration features
- Workflows demanding real-time auto-sync across multiple devices
- Users needing extensive plugin ecosystems or third-party integrations
How teams use it
Testing Image Processing APIs
Directly preview generated images, thumbnails, and visual transformations without downloading files or switching tools
Flutter/Dart API Integration
Generate Dart http or dio code snippets instantly, paste into Flutter projects, and run on DartPad for rapid prototyping
Multi-Platform Development
Test APIs on iPad during commute, continue on desktop workstation, and export HAR files for version control and team sharing
Migrating from Postman
Import existing Postman collections, validate endpoints, generate Python or JavaScript integration code, and export to HAR for CI/CD pipelines

Frequently asked questions
What makes API Dash different from Postman or Insomnia?
API Dash natively previews multimedia responses (images, PDFs, audio) in-app and generates code for 25+ language/library combinations. It also runs on iOS/iPad, unlike most desktop-only API clients.
Can I import my existing Postman or Insomnia collections?
Yes. API Dash supports importing collections from Postman, Insomnia, OpenAPI specs, cURL commands, and HAR files. You can also export your work as HAR for portability.
Which programming languages are supported for code generation?
API Dash generates code for Dart, JavaScript, Python, Kotlin, Java, C#, Go, PHP, Ruby, Rust, Swift, C, and Julia using popular libraries like axios, requests, okhttp3, and more.
Does API Dash support WebSocket or gRPC?
Not yet. WebSocket, gRPC, MQTT, and hurl import are planned features currently tracked in the project's GitHub issues.
Where is my API request data stored?
Data is persisted locally on your device. You control when to save by pressing the Save button. No cloud sync or external servers are involved.
