httptui

Interactive terminal UI for .http files.

httptui is a fast, keyboard-driven REST client that lives in your terminal. It parses .http and .rest files, allowing you to browse and execute requests without leaving your workflow.

Features

• Multi-Format Support: Parse .http, .rest, Postman collections, and OpenAPI specs (JSON/YAML).
• Keyboard-Driven TUI: Vim keys, split-panel layout, details panel (d), fullscreen (f), help overlay (?).
• Environment Management: Load environment files, register named environments, switch at runtime (E).
• mTLS & Client Certificates: Per-host client certificates (PEM/PFX) with wildcard matching.
• Export as .http: Save requests to .http format with variables preserved (S).

Requirements

• Node.js 24 or newer. httptui declares engines.node: ">=24"; installing on older Node versions will trigger an EBADENGINE warning from npm and is not supported.

Installation

npm install -g httptui

Or

# npm config get prefix
# npm config set prefix "$HOME/.local"
# npm config delete prefix

cd <project-folder>
npm install
npm run build
npm link

# npm unlink httptui

Usage

httptui path/to/api.http
httptui postman-collection.json
httptui openapi.yaml
httptui openapi.json

You can also open a different .http file from within the running TUI by pressing o and typing the file path. This is useful when working across multiple API definition files without restarting httptui.

Options
