Environments

Switch between sets of variables (dev, staging, production) without editing individual requests.

How It Works

An environment is a named collection of key-value variables. When you send a request, the backend substitutes any {{variable_name}} placeholders in the URL, headers, and body with the values from the active environment.

URL:    {{base_url}}/users/{{user_id}}
Header: Authorization: Bearer {{api_token}}

If the active environment has base_url = https://api.example.com, user_id = 42, and api_token = sk_abc123, the outgoing request becomes:

GET https://api.example.com/users/42
Authorization: Bearer sk_abc123

Managing Environments

Open the Manage Environments dialog from the Environments page (or the environment selector in the header).

Sidebar actions:

• New Environment - creates an empty environment
• Import - load an environment from a JSON file

Per-environment actions (buttons in the environment header):

• Set Active / Deactivate - choose which environment supplies variable values
• Duplicate - copy an environment with all its variables
• Export - download the environment as a JSON file
• Delete - remove the environment (with confirmation)
• Rename - double-click the environment name to edit it

Variables

Each variable has:

Field	Description
Key	The name you reference with {{key}}
Value	The substituted value
Enabled	Toggle - disabled variables are skipped during substitution
Secret	Toggle - masks the value in the UI (eye icon to reveal)

Add variables in the editor table. Click the + row to add a new one, or remove with the trash icon.

Variable Autocomplete

The VariableAwareInput fields throughout the app (URL bar, header values, etc.) show an autocomplete dropdown when you start typing a variable reference. It lists all variables from the active environment so you can pick the right name.

Switching Environments

Use the environment selector dropdown in the header bar. Selecting a different environment changes which variables are substituted - you don't need to edit any requests.

Where Variables Are Substituted

The backend replaces {{variable}} placeholders in:

• Request URL
• Header values
• Request body

Substitution is a single pass - variables cannot reference other variables (no nesting).

Variable names are case-sensitive: {{api_key}} and {{API_KEY}} are different variables.
