Features

Echo is a desktop HTTP client: organize requests, reuse environments and variables, and inspect responses in a focused dark UI.

Collections tree

Keep folders and requests in a sidebar. Select a request to edit and send it; the response opens below.

Request bar

Choose the method, edit the URL, and send. Query parameters and headers are first-class.

Environments and variables

Define variables per environment and use {{variableName}} in the URL, headers, query, body, and auth fields. Each request picks an environment; add, rename, duplicate, or delete shared definitions.

Secrets (desktop)

On the packaged app, store sensitive values in the OS credential manager and reference them with {{secret:NAME}}. They are not written into exported workspace JSON.

Authentication

None, Bearer token, Basic, or API key—sent as a header or query parameter depending on your choice.

Query and headers

Key/value editors for query string and request headers.

Body

Send JSON, raw text, or form bodies alongside your request.

Response

Inspect status, timing, and body. Switch views such as raw and pretty for structured content.

Completion scripts

Run an optional script after a successful response: pm.response.status(), pm.response.text(), pm.response.json(), and pm.console.log(...).

Import and export

Right-click a folder to export the full workspace as JSON or import a file to replace the current workspace—handy for backup and sharing.
