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.
Hey Product Hunt! We built OpenSider because local agents like Claude Code and Cursor CLI kept starting a fresh browser: no logins, no tabs, no context. So we flipped the setup — the browser you already use hands the live page to your local agent.
Drive Claude Code CLI, Codex CLI, OpenCode CLI, Cursor CLI and other local CLIs straight from your browser: real sessions, real cookies, real pages. Fully local, fully open source — star it and tell us what you'd automate first!
