Servers & authentication

Mon, 01 Jan 0001 00:00:00 +0000

Each API server carries a name, a base URL and an auth provider, so switching from localhost to staging is a dropdown — not a find-and-replace across your requests. Auth providers cover no-auth, a static bearer token, and OIDC with .well-known autodiscovery.

User login with PKCE

Mon, 01 Jan 0001 00:00:00 +0000

The interactive OIDC leg: the app opens your identity provider in a real browser, catches the redirect on a locally-run server, and exchanges the code for tokens using PKCE. Triggered lazily, cancellable mid-flow.

The request builder

Mon, 01 Jan 0001 00:00:00 +0000

Method, path, headers and body — with the resolved URL previewed live as you type, headers you can switch off without deleting, and a JSON body editor that validates and formats.

Variables & placeholders

Mon, 01 Jan 0001 00:00:00 +0000

Write {userId} in the path or query and {{userName}} in the body. Placeholders are detected automatically, collected into a Variables tab, URL-encoded where they belong, and stored in history as a template — so replaying only needs new values.

Timing & replayable history

Mon, 01 Jan 0001 00:00:00 +0000

Every request is measured end-to-end and every attempt is recorded, grouped by server + path. Click an entry to load it back into the editor and send it again.

Collections

Mon, 01 Jan 0001 00:00:00 +0000

Bookmark the current request into a named collection, with an optional description. A sidebar toggle flips between History and Collections; one collection is shown at a time, and the filter box tells you when a match lives in another one.

Import, backup & restore

Mon, 01 Jan 0001 00:00:00 +0000

Bring requests in from OpenAPI or Postman, and write every collection out to a versioned JSON file — with a restore that previews the file first and asks whether to merge or replace.

The session console

Mon, 01 Jan 0001 00:00:00 +0000

A session-only log of everything that went over the wire, each row expandable to the full detail — and that includes the OIDC token grant and discovery calls, recorded exactly as sent.

Execution & sync

Mon, 01 Jan 0001 00:00:00 +0000

Run requests on device or delegate them to a proxy server to get past CORS and into private networks. Store config and history locally or sync them to a cloud endpoint. Both are switchable at runtime.

One app, every screen

Mon, 01 Jan 0001 00:00:00 +0000

A multi-pane layout on desktop and web, and a bottom-tab layout on phones — Request · Response · Library · Servers. The same app in both; only the arrangement changes.
