Your local AI agent shouldn't start from scratch. Agent tools like Playwright and Browser MCP cold-start a headless browser, losing your logins, tabs, and context. OpenSider flips the setup: the browser you already use hands the live page to your local agent. Drive Claude Code, Copilot CLI, OpenCode CLI, Cursor CLI, and other local agents from the browser for web gathering and automation, sessions intact. Fully local, open source, and works across Chromium browsers.
