Features

Everything a request needs. Nothing it doesn't.

Private by default

Requests, responses and secrets stay on your machine.

  • No account, no cloud sync
  • Secrets live in the OS keychain, never in your files
  • Zero telemetry
  • Requests go straight to your servers

Plain files, your Git

Collections are folders of YAML that you own.

  • One YAML file per request
  • Diff, review and commit like code
  • Variables and environments per collection
  • Import from curl, Postman, Insomnia and OpenAPI

A complete request client

Compose, send and dig into the response.

  • JSON, form, multipart and file bodies
  • Bearer, Basic, API-key and OAuth2 auth
  • Timing per phase, headers, cookies, SSE and NDJSON streams
  • ⌘K command palette, ⌘↵ to send

Fast, and scriptable

A native core, plus tools to test and automate.

  • Java core compiled with GraalVM, no JRE bundled
  • Declarative assertions on responses
  • Capture values from one response into the next request
  • Run whole collections from the CLI or CI

In the app

Quiet by design.

A dense, focused workspace that gets out of the way.
