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.
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.
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.
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.
When teams consider API Dash, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
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
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.
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.
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.
Not yet. WebSocket, gRPC, MQTT, and hurl import are planned features currently tracked in the project's GitHub issues.
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.
