01
A native shell, not a bundled browser
ReqTone is a Tauri v2 application. It renders in the webview your operating system already provides and does its networking in Rust with reqwest, on a real thread, rather than shipping a browser engine and a JavaScript runtime alongside the app. The trade is that the UI inherits whatever webview your OS gives it — which is why both themes are tested on all three platforms rather than assumed.
02
Your data is a file you own
Collections, project trees, environments, auth profiles and history are rows in an ordinary SQLite database in your OS application directory. You can copy it, diff it, back it up, keep it on an encrypted volume, point the app at a different one, or open it in any SQLite browser without asking us. Export to JSON or Postman format is there too, so leaving is a file operation rather than a support ticket.
03
Nothing waits on the network to start
There is no account, no licence check and no auto-updater, and it is a standing rule in the project that nothing on the startup path may block on a network call. The app opens with the cable out. What it contacts is covered in full on the privacy page — the short version is the endpoint in your request, an OAuth token URL you configured, and your own sync server if you turn one on.
04
Streaming is the default path, not a mode
Every request goes down the same streaming code path, so a response renders as it is written and the window stays usable while the stream is open. There is no separate event-stream request type to switch into and no second implementation that behaves differently — which also means a POST with a JSON body streams, which is what most LLM endpoints need.
05
Scopes resolve one way
A variable is resolved request first, then project, then global. A staging token and a sandbox token can both be called {{token}} without either surprising you, and the manager shows which values are unused and whether a value lands in params, body or headers.
06
Getting work in and out is a file operation
Postman Collection v2.1, OpenAPI and Swagger 3.0 in JSON or YAML, raw cURL commands and .reqtone archives all import, bringing folder trees, headers, query params, auth profiles and bodies with them. Export runs the same way, to clean JSON or Postman format. And when a service has no collection to import at all, a ready-made prompt has a coding agent read the backend and write the import file — a folder per controller, a request per route, example bodies built from your own DTOs.
