A lightweight native API client, a Postman alternative

A native API client written entirely in Rust: no Electron, no account, first frame in about 40 ms. HTTP, GraphQL, gRPC, WebSocket, Socket.IO, MQTT, SOAP, MCP and AI requests in one app. Postman collections, environments and pm.* scripts import and run unchanged. Git-friendly workspaces with secrets in the keychain, a collection runner and a newman-compatible CLI for CI, visual Flows, Spec Hub for OpenAPI, plus a local mock server. Free and open source.

Hi Product Hunt! 👋
I built TernaryWire because I wanted Postman's power without the Electron weight, the forced account and the cloud sync.
One native Rust binary — first frame in ~40 ms, under 90 MB of memory; a 100 MB response streams to disk
HTTP, GraphQL, gRPC, WebSocket, Socket.IO, MQTT, SOAP, MCP and AI model requests in one app
Postman compatible: collections, environments and pm.* scripts run unchanged (50/50 on a corpus of real Postman scripts)
Git-friendly workspaces: one file per request, secrets kept in the keychain, never in the repo
ternarywire run is newman-compatible, so it can replace newman in CI
Flows (visual request chaining), Spec Hub for OpenAPI/AsyncAPI/Protobuf, mock server, webhook listener and capture proxy
No account, no telemetry. Free and open source for macOS, Windows and Linux. I'd love to know what would make you switch from your current API client!
