OpenCLI
Turn websites into CLI commands while reusing an existing Chrome login session when needed.
When to Use
- You need data from a website that already works in the browser but does not expose a clean public API.
- You want browser-backed extraction without exporting credentials out of Chrome.
- You want structured output from a website in
table, json, md, or csv.
- You want to explore a site, generate an adapter, probe auth strategy, or smoke-test a generated workflow.
Install
npm install -g @jackwener/opencli
opencli list
Prerequisites
Browser-backed commands require:
- Chrome running and already logged into the target site
- Playwright MCP Bridge installed
PLAYWRIGHT_MCP_EXTENSION_TOKEN configured for the Playwright MCP server
Public API commands such as hackernews, v2ex, and some github search flows do not need the browser setup.
Core Usage
opencli <site> <command> [flags]
opencli list
opencli list --json
opencli hackernews top --limit 5 -f json
opencli bilibili hot --limit 10
opencli github search --keyword "cli"
AI-Native Workflows
opencli explore <url> --site <name>
opencli synthesize <site>
opencli generate <url> --goal "hot"
opencli cascade <api-url>
opencli verify <site/name> --smoke
explore: inspect a site and capture artifacts for later generationsynthesize: generate adapters from existing explore artifactsgenerate: run the end-to-end explore to register flow in one stepcascade: auto-probe auth strategy from public to cookie to headerverify: smoke-test a generated adapter
If you need to build new adapters, read references/cli-creator.md.
Output And Debugging
opencli <site> <command> -f table
opencli <site> <command> -f json
opencli <site> <command> -f md
opencli <site> <command> -f csv
opencli <site> <command> -v
Common Targets
- Browser-backed:
bilibili, zhihu, xiaohongshu, twitter, reddit, weibo, youtube, boss, yahoo-finance, reuters, smzdm, ctrip
- Public or mixed:
hackernews, v2ex, github, bbc
Notes
- Tabs opened during execution are usually auto-closed afterwards.
- If a browser command returns empty data, first verify the site is reachable in Chrome and the session is logged in.
