API Dash is a beautiful AI-powered open-source cross-platform (Desktop & Mobile) API Client built using Flutter which can help you easily create & customize your HTTP & GraphQL API requests, visually inspect responses and generate API integration code. A lightweight alternative to postman/insomnia.
API Dash is a Flutter-built, cross-platform desktop/mobile API client positioned as an open-source alternative to Postman and Insomnia, covering REST, GraphQL, WebSocket, MQTT, gRPC, and SSE in one app with an AI chat assistant (DashBot) bolted on top. It's aimed at developers who want a native, non-Electron API testing tool and don't mind an app still finding its footing.
Protocol coverage is genuinely wide for a single client — REST, GraphQL, WebSocket, MQTT and gRPC in one tool is more than most Postman alternatives attempt. Code generation spans 15+ language/library combinations (Rust's hyper/reqwest/ureq, Swift's Alamofire, Go's net/http) with a maintained table, not just curl-to-two-languages. Multimedia response previewing (images, PDF, audio, video) directly in the response pane is a real gap in Postman/Insomnia that this fills. It's Flutter rather than Electron, so the desktop builds are lighter and startup is faster than the usual API client competition.
The repo tree is dominated by hundreds of GSoC proposal markdown files committed directly into doc/proposals — that's process cruft mixed into source control, not documentation, and makes the repo harder to navigate for someone just trying to use the tool. DashBot is marketed as a headline feature but the README never says what happens to your request/response data when you point it at a cloud model, which matters if people are testing against anything non-public. The CSV preview is flagged 'Can be improved' in their own docs, and HAR/hurl import is still an open issue rather than shipped. As a GSoC-heavy project with a large rotating contributor base, code consistency and long-term maintenance ownership are worth watching before depending on it for team workflows.
