OpenCLI

Turn websites, browser sessions, Electron apps, and local tools into deterministic interfaces for humans and AI agents.
Reuse your logged-in browser, automate live workflows, and crystallize repeated actions into reusable CLI commands.

OpenCLI gives you one surface for three different kinds of automation:

• Use built-in adapters for sites like Bilibili, Zhihu, Xiaohongshu, Reddit, HackerNews, Twitter/X, and many more.
• Drive a live browser directly with opencli browser when an AI agent needs to click, type, extract, or inspect a page in real time.
• Generate new adapters from real browser behavior with explore, synthesize, generate, and cascade.

It also works as a CLI hub for local tools such as gh, docker, and other binaries you register yourself, plus desktop app adapters for Electron apps like Cursor, Codex, Antigravity, ChatGPT, and Notion.

Highlights

• Desktop App Control — Drive Electron apps (Cursor, Codex, ChatGPT, Notion, etc.) directly from the terminal via CDP.
• Browser Automation — browser gives AI agents direct browser control: click, type, extract, screenshot — fully scriptable.
• Website → CLI — Turn any website into a deterministic CLI: 87+ pre-built adapters, or generate your own with opencli generate.
• Account-safe — Reuses Chrome/Chromium logged-in state; your credentials never leave the browser.
• AI Agent ready — explore discovers APIs, synthesize generates adapters, cascade finds auth strategies, browser controls the browser directly.
• CLI Hub — Discover, auto-install, and passthrough commands to any external CLI (gh, docker, obsidian, etc).
• Zero LLM cost — No tokens consumed at runtime. Run 10,000 times and pay nothing.
• Deterministic — Same command, same output schema, every time. Pipeable, scriptable, CI-friendly.

Quick Start

1. Install OpenCLI

npm install -g @jackwener/opencli

2. Install the Browser Bridge Extension

OpenCLI connects to Chrome/Chromium through a lightweight Browser Bridge extension plus a small local daemon. The daemon auto-starts when needed.

1. Download the latest opencli-extension-v{version}.zip from the GitHub Releases page.
2. Unzip it, open chrome://extensions, and enable Developer mode.
3. Click Load unpacked and select the unzipped folder.

3. Verify the setup

opencli doctor

4. Run your first commands

opencli list
opencli hackernews top --limit 5
opencli bilibili hot --limit 5

For Humans

Use OpenCLI directly when you want a reliable command instead of a live browser session:

• opencli list shows every registered command.
• opencli <site> <command> runs a built-in or generated adapter.
• opencli register mycli exposes a local CLI through the same discovery surface.
• opencli doctor helps diagnose browser connectivity.

For AI Agents

Use two different entry points depending on the task:

• skills/opencli-explorer/SKILL.md: the entry point for creating new adapters — supports both fully automated generation (opencli generate <url>) and manual exploration workflows.
• skills/opencli-browser/SKILL.md: the low-level control surface for live browsing, debugging, and manual intervention.

Install the packaged skills with:

npx skills add jackwener/opencli

Or install only what you need:

npx skills add jackwener/opencli --skill opencli-usage
npx skills add jackwener/opencli --skill opencli-browser
npx skills add jackwener/opencli --skill opencli-explorer
npx skills add jackwener/opencli --skill opencli-oneshot

In practice:

• start with opencli-explorer when the agent needs a reusable command for a site (it covers both automated and manual flows)
• use opencli-browser when the agent needs to inspect or steer the page directly

Available browser commands include open, state, click, type, select, keys, wait, get, screenshot, scroll, back, eval, network, init, verify, and close.

Core Concepts

browser: live control

Use opencli browser when the task is inherently interactive and the agent needs to operate the page directly.

Built-in adapters: stable commands

Use site-specific commands such as opencli hackernews top or opencli reddit hot when the capability already exists and you want deterministic output.

explore / synthesize / generate: create new CLIs

Use these commands when the site you need is not covered yet:

• explore inspects the page, network activity, and capability surface.
• synthesize turns exploration artifacts into evaluate-based JS adapters.
• generate runs the verified generation path and returns either a usable command or a structured explanation of why completion was blocked or needs human review.

cascade: auth strategy discovery

Use cascade to probe fallback auth paths such as public endpoints, cookies, and custom headers before you commit to an adapter design.

CLI Hub and desktop adapters

OpenCLI is not only for websites. It can also:

• expose local binaries like gh, docker, obsidian, or custom tools through opencli <tool> ...
• control Electron desktop apps through dedicated adapters and CDP-backed integrations

Prerequisites

• Node.js: >= 21.0.0 (or Bun >= 1.0)
• Chrome or Chromium running and logged into the target site for browser-backed commands

Important: Browser-backed commands reuse your Chrome/Chromium login session. If you get empty data or permission-like failures, first confirm the site is already open and authenticated in Chrome/Chromium.

CLI Hub

OpenCLI acts as a universal hub for your existing command-line tools — unified discovery, pure passthrough execution, and auto-install (if a tool isn't installed, OpenCLI runs brew install <tool> automatically before re-running the command).

External CLI	Description	Example
gh	GitHub CLI	opencli gh pr list --limit 5
obsidian	Obsidian vault management	opencli obsidian search query="AI"
docker	Docker	opencli docker ps
lark-cli	Lark/Feishu — messages, docs, calendar, tasks, 200+ commands	opencli lark-cli calendar +agenda
dingtalk	DingTalk — cross-platform CLI for DingTalk's full suite, designed for humans and AI agents	opencli dingtalk msg send --to user "hello"
wecom	WeCom/企业微信 — CLI for WeCom open platform, for humans and AI agents	opencli wecom msg send --to user "hello"
vercel	Vercel — deploy projects, manage domains, env vars, logs	opencli vercel deploy --prod

Register your own — add any local CLI so AI agents can discover it via opencli list:

opencli register mycli

Desktop App Adapters

Control Electron desktop apps directly from the terminal. Each adapter has its own detailed documentation:

App	Description	Doc
Cursor	Control Cursor IDE — Composer, chat, code extraction	Doc
Codex	Drive OpenAI Codex CLI agent headlessly	Doc

0	Success	Command completed normally
1	Generic error	Unexpected / unclassified failure
2	Usage error	Bad arguments or unknown command
66	Empty result	No data returned (EX_NOINPUT)
69	Service unavailable	Browser Bridge not connected (EX_UNAVAILABLE)
75	Temporary failure	Command timed out — retry (EX_TEMPFAIL)
77	Auth required	Not logged in to target site (EX_NOPERM)
78	Config error	Missing credentials or bad config (EX_CONFIG)
130	Interrupted	Ctrl-C / SIGINT

For AI Agents (Developer Guide)

Quick mode: To generate a single command for a specific page URL, see opencli-oneshot skill — just a URL + one-line goal, 4 steps done.

Full mode: Before writing any adapter code, read opencli-explorer skill. It contains the complete browser exploration workflow, the 5-tier authentication strategy decision tree, and debugging guide.

opencli explore https://example.com --site mysite   # Discover APIs + capabilities
opencli synthesize mysite                            # Generate JS adapters
opencli generate https://example.com --goal "hot"   # One-shot: explore → synthesize → register
opencli cascade https://api.example.com/data         # Auto-probe: PUBLIC → COOKIE → HEADER

Testing

See TESTING.md for how to run and write tests.

Troubleshooting

• "Extension not connected" — Ensure the Browser Bridge extension is installed and enabled in chrome://extensions in Chrome or Chromium.
• "attach failed: Cannot access a chrome-extension:// URL" — Another extension may be interfering. Try disabling other extensions temporarily.
• Empty data or 'Unauthorized' error — Your Chrome/Chromium login session may have expired. Navigate to the target site and log in again.
• Node API errors — Ensure Node.js >= 21. Some features require node:util styleText (stable in Node 21+).
• Daemon issues — Check status: curl localhost:19825/status · View logs: curl localhost:19825/logs
