After complaining to Grok about his browser, dev built Serein, an agentic browser harness

Dev @Av1dlive kept complaining to his Grok bot about his browser — so it built him one. Together with @ziwenxu he shipped Serein, a free "agentic harness" for the browser: chat with Claude Code or Codex inside it, let them control tabs and do the work, and use tools already on your Mac. The pitch: your browser is their workspace now.
