Show HN: Browsentic Open-source Claude for Chrome alternative for any agent CLI

Developer imshaikot released Browsentic v0.8.0, an Apache 2.0 open-source agentic browser harness, its first public stable launch, per the project's GitHub repository. 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.

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. A free, opensource Apache 2.0 with rich capabilities alternative to Comet, BrowserOS, Browser-use, Claude for Chrome or nanobrowser. The 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. Browsentic 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. Capabilities: 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 It is opensource, no API key, no telemetry & local first and actively maintained and yesterday was the first public stable launch v0.8.0 Currently I'm the only author but every & any contribution or suggestion will be more than welcome : Source: https://github.com/imshaikot/browsentic https://github.com/imshaikot/browsentic Install guide: https://browsentic.com/install https://browsentic.com/install Docs: https://browsentic.com/docs https://browsentic.com/docs Install video: https://www.youtube.com/watch?v=o8t4l9Q9BkE https://www.youtube.com/watch?v=o8t4l9Q9BkE Comments URL: https://news.ycombinator.com/item?id=49964361 https://news.ycombinator.com/item?id=49964361 Points: 1 Comments: 0
