Every time you ask an AI to read information from an external website, the reply is always "Sorry, I can't directly access those sites". OpenCLI is an open-source command-line tool built to solve exactly this problem; it has already accumulated 20k+ stars on GitHub.

Its core idea is simple: turn everything you normally do in a browser into one-line commands in the terminal. What's more, the commands execute directly in your local browser without going through LLM inference, so you can run them as many times as you like without spending a single token.

What Is OpenCLI

OpenCLI is an open-source command-line toolkit with 100+ built-in site adapters, covering mainstream platforms such as Xiaohongshu, Bilibili, Zhihu, Douban, Hupu, Reddit, HackerNews, and Google Scholar. Beyond web data, it can also tap private chat and office data from WeChat, Telegram, Discord, Feishu, WeCom, DingTalk, and more.

Core Features

Scrape the Whole Web with One Command

No need to manually copy cookies or assemble request headers — OpenCLI directly reuses your Chrome login state:

# Search Zhihu
opencli zhihu search "AI Agent"

# Download a Zhihu article
opencli zhihu download --url "article URL" --output ./zhihu

# See what Reddit is discussing
opencli reddit search "AI"

# See Bilibili trending
opencli bilibili trending

Output formats include JSON, CSV, and Markdown, making it easy to feed results straight into a knowledge base or a data-analysis pipeline.

Unified Access to Private Chat Logs

OpenCLI unifies chat logs from WeChat, Telegram, and Discord under command-line access:

# Search WeChat chat logs
opencli wx search "keyword"

# Search Telegram messages
opencli tg search "keyword"

# Check recent Discord messages
opencli discord recent

WeChat uses the separate wx-cli tool; the install command:

npm install -g @jackwener/wx-cli

First use requires wx init to initialize (sudo wx init on macOS); it automatically detects the WeChat data directory and scans the database key from memory. After that, wx session pulls the conversation list and wx history searches past messages.

Chat log output supports JSON and CSV and can plug into knowledge-management tools like Obsidian, turning fragments scattered across apps into a continuously updated personal information stream.

The Full Office Suite

• opencli lark-cli covers 200+ Feishu commands (messages, docs, calendar, tasks)
• opencli wecom-cli manages WeCom
• opencli dws manages DingTalk

Desktop App Automation

Via the CDP protocol, OpenCLI can directly drive Electron desktop apps: Cursor, the ChatGPT macOS app, Notion, the Discord desktop client, and more — no manual mouse clicking needed.

Quick Start

Installation

Requires Node.js 21+; one command does it:

npm install -g @jackwener/opencli

After installing, run opencli list to see every available command.

Install the Chrome Extension

Download the OpenCLI extension from the Chrome Web Store and enable developer mode. No manual cookie configuration needed — OpenCLI reuses your Chrome login state directly.

Your Site Isn't Supported?

With the opencli-adapter-author skill, an agent can write adapters for you automatically:

npx skills add jackwener/opencli --skill opencli-adapter-author

There is also a community plugin system: opencli plugin install installs adapters others have written with a single command.

The Secret to Zero Token Consumption

The biggest difference between OpenCLI and "letting an LLM operate the browser itself" is that CLI commands execute directly in your local browser without passing through LLM inference. The same command yields consistently structured results — pipeable, scriptable, and CI/CD-friendly.

Essentially, it pulls browser automation back from AI inference to system calls.

Who It's For

• Content creators: batch-download assets, scrape comment data, analyze audience profiles
• E-commerce practitioners: export customer-service chat logs in one click, archive user feedback in bulk
• Developers: wire website data into automation pipelines, CI/CD-script friendly
• Data analysts: unified multi-platform data collection, structured output straight into your database

Note: OpenCLI as an open-source project provides tools and ideas; actually accessing and deploying private data is a personal matter — assess compliance risks and privacy boundaries before use.
