Browsentic runs a loopback MCP server that spawns Claude Code, Codex, OpenCode or Cursor CLI harnesses in a detached process, supports Firefox as well as Chromium, and needs no CDP for core agentic browsing. The project claims 50+ core accessibility tools versus nanobrowser's 20, plus custom skills, record-replay, scheduled monitoring notifications, autonomous captcha resolution, memory, a voice orb over the Web Speech API, and custom tool sideloading, with no API key or telemetry.", "body_md": "A personal agent harness lives in your existing browser, connects to your claude-code (or any other major harness codex or cursor-cli...) NOT the SDK API, exposes web-optimized tools to the harness - that's Browsentic.\n\nA free, opensource (Apache 2.0) with rich capabilities alternative to Comet, BrowserOS, Browser-use, Claude for Chrome or nanobrowser.\n\nThe unique architecture of Browsentic makes it different from all other alternatives. It uses a loopback MCP server that spawns claude/codex/OpenCode/Cursor harness in a detached process. You can already guess, it is a bi-directional MCP, you can browse agentic through the browser harness or through any MCP client.\n\nBrowsentic doesn't require any new browser to install and not limited to chromium, it supports Firefox as well. By default you don't even need CDP to perform core agentic browsing.\n\nCapabilities: core accessibilities (50+ compare to nanobrowser only had 20), custom skill, record-replay, schedule-monitoring-notification, resolves captcha autonomously, has it's own memory, voice orb over web-speech API, can sideload custom tools, platform + browser + agent agnostic\n\nIt is opensource, no API key, no telemetry & local first and actively maintained and yesterday was the first public stable launch (v0.8.0)\n\nCurrently I'm the only author but every & any contribution or suggestion will be more than welcome :)\n\nSource: [https://github.com/imshaikot/browsentic](https://github.com/imshaikot/browsentic)\n\nInstall guide: [https://browsentic.com/install](https://browsentic.com/install)\n\nDocs: [https://browsentic.com/docs](https://browsentic.com/docs)\n\nInstall video: [https://www.youtube.com/watch?v=o8t4l9Q9BkE](https://www.youtube.com/watch?v=o8t4l9Q9BkE)\n\nComments URL: [https://news.ycombinator.com/item?id=49964361](https://news.ycombinator.com/item?id=49964361)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-browsentic-open-source-claude-for-chrome-alternative-for-any-agent-cli", "canonical_source": "https://github.com/imshaikot/browsentic", "published_at": "2026-10-05 13:08:05+00:00", "updated_at": "2026-10-05 13:20:52.701362+00:00", "lang": "en", "topics": ["ai-agents", "agent-protocols", "ai-tools", "developer-tools", "ai-products"], "entities": ["Browsentic", "imshaikot", "Claude Code", "Codex", "OpenCode", "Cursor", "Firefox", "nanobrowser"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-browsentic-open-source-claude-for-chrome-alternative-for-any-agent-cli", "markdown": "https://wpnews.pro/news/show-hn-browsentic-open-source-claude-for-chrome-alternative-for-any-agent-cli.md", "text": "https://wpnews.pro/news/show-hn-browsentic-open-source-claude-for-chrome-alternative-for-any-agent-cli.txt", "jsonld": "https://wpnews.pro/news/show-hn-browsentic-open-source-claude-for-chrome-alternative-for-any-agent-cli.jsonld"}}
