OpenCLI

Overview

OpenCLI is an open-source framework that transforms any website into a command-line interface through browser automation and AI agents. With over 26,700 GitHub stars, it enables developers to control web applications via terminal commands, bridging the gap between browser-based SaaS tools and CLI workflows.

Developed by jackwener, OpenCLI uses a headless browser combined with an AI agent to interpret natural language commands and execute corresponding browser actions. This eliminates the need for per-site API integrations—any website becomes automatable.

Features

• Natural Language to Browser Actions: Describe what you want; OpenCLI navigates, clicks, fills forms, and extracts data
• Session Persistence: Maintain browser sessions across commands with cookies and auth state
• Scaffolded CLI Interface: Each site gets a generated CLI with discoverable subcommands
• Data Extraction: Query web content and return structured data (JSON, CSV, tables)
• Automation Recipes: Share and reuse command sequences for common workflows
• Multi-Site Support: Connect to multiple websites simultaneously
• JavaScript/TypeScript Core: Built for Node.js environments

Installation

npm install -g opencli
# or
npx opencli connect https://example.com

Quick Start

# Connect to a website
opencli connect https://github.com

# Execute a natural language command
opencli run "Find repos with over 100k stars in TypeScript"

# Extract structured data
opencli extract "List all trending Python repos" --format json

Core Concepts

Browser Session

OpenCLI maintains a persistent browser instance with auth state, enabling authenticated interactions.

AI Interpreter

A language model parses natural language commands into browser actions (navigate, click, type, wait, extract).

Recipe

Reusable command sequences saved as recipes for team sharing.

Advanced Features

Custom Command Definitions

const command = {
  name: 'create-issue',
  description: 'Create a GitHub issue',
  args: ['title', 'body'],
  action: ({ title, body }) => `Create an issue with title "${title}"`,
};

Data Pipeline Integration

opencli extract "Get all open PRs" | jq '.[] | .title' | xargs opencli run "Review PR"

Examples

• GitHub CLI: Create issues, review PRs, manage repos from the terminal
• Jira Automation: Create tickets, update statuses, query boards
• E-commerce Research: Extract product prices, reviews, and specs from any store
• Sales Pipeline Management: Query and update Salesforce or HubSpot from CLI

Pros

• ✅ Any website becomes automatable—no API required
• ✅ Natural language interface reduces learning curve
• ✅ Session persistence for authenticated workflows
• ✅ Recipe sharing enables team collaboration

Cons

• ❌ Browser automation is slower than direct API calls
• ❌ Site UI changes can break automation recipes
• ❌ Requires active network and browser resources
• ❌ Not suitable for high-frequency automated operations

When to Use

Use OpenCLI when you need to automate websites that lack public APIs, or when building CLI wrappers around SaaS tools. Ideal for data extraction, administrative task automation, and prototyping browser-based workflows.
