Monkeytail on the Mac with a collection tree, request editor and JSON response

A drop-in replacement for Postman and Insomnia

Open the collections you already have and run them the same way. No Monkeytail account, no login wall, no cloud workspace and no telemetry.

Import everything

Postman collections, environments, globals and data dumps; Insomnia v4 and v5; Bruno, Hoppscotch, Thunder Client, HAR, .http files, OpenAPI and cURL. Pick a whole folder at once.

Or pull from the cloud

Sign in to Postman, Insomnia or Hoppscotch once to pull your synced workspaces, or point at a GitHub repository. The session is used for that import only and never saved.

Your scripts keep working

A Postman-compatible pm API with pm.test, pm.expect, pm.sendRequest, CryptoJS, lodash and moment. Insomnia and Bruno scripts run too.

The same mental model

Workspaces, collections and nested folders that inherit auth, headers, variables and scripts. Environments, globals and {{variables}}, including {{$guid}}.

Export back any time

Postman v2.1, Insomnia v4 or a full-fidelity Monkeytail JSON file. Your data is never locked in.

Native, not a web view

Built in SwiftUI for each Apple platform, with keyboard shortcuts on the Mac and a thumb-friendly editor on iPhone.

A full API client in your pocket

The same workspace on iPhone, iPad and Mac, synced through your own iCloud Drive.

JSON response on iPhone Response tree on iPhone Request body editor on iPhone OAuth 2.0 settings on iPhone

Everything else you'd expect

And a few things you might not.
